What is a Bungee Cord?

A bungee cord or occy strap is a stretchy rope made from one or more elastic strands forming a core, usually covered in a woven cotton, polypropylene or nylon sheath. These cords are renowned for their ability to absorb shock, thanks to the elasticity of the material.

Bungee cords are commonly used to secure objects without tying knots and to absorb shock. With hooks on each end, they can be looped around items and hooked onto themselves for a firm grip. They’re particularly useful for securing loads on vehicles, like utes, trucks, or trailers, where the load may move due to road vibration or wind resistance.

One of the main advantages of bungee cords is that they can be adjusted to suit the size and shape of the load. This makes them a handy tool for various applications, from everyday household use to professional trades and outdoor adventures.

How Bungee Cords Work

Explanation of How a Bungee Cord Works

Bungee cords work based on the principles of potential and kinetic energy. 

  1. When a bungee cord is stretched, it stores potential energy. Similar to when you pull back on a slingshot – you’re putting energy into the system. In the case of the bungee cord, the energy comes from the effort you put into stretching it. This energy is then stored in the cord, waiting to be released.
  2. When the tension on the bungee cord is released, the stored potential energy converts into kinetic energy, which is the energy of motion. The cord reverts back to its original length, releasing the stored energy.

This ability to store and release energy is what makes bungee cords so effective at securing loads. When you stretch a bungee cord around an object and hook it in place, the cord’s tension creates a firm hold on the object, preventing it from moving. The elasticity of the cord also allows it to absorb shocks and vibrations, ensuring the load remains secure under changing conditions.

In the case of Spider Tarp’s bungee cords, Spider Cords, they have an additional feature – the patented Spider-Lock™ hook, which allows the length of the cord to be quickly and easily adjusted and locked in place. This feature enhances the versatility of the bungee cord, allowing a single Spider Cord to securely hold loads of different shapes and sizes.

Materials that make bungee cords work

At the core of a bungee cord, you’ll find strands of elastic material, usually rubber, which give the cord its stretchiness. This elasticity allows the cord to absorb shocks and firmly hold items in place. The rubber strands are capable of being stretched and then returning to their original shape, thanks to the molecular structure of rubber.

Covering these rubber strands is a woven sheath, typically made from polypropylene, cotton or a tough, wear-resistant material like nylon that is used on all Spider-Cords™. This outer layer protects the inner rubber strands from damage and wear, while also providing a grip for users.

Bungee cords usually have metal or plastic hooks attached at each end, which are used to secure the cord once it’s stretched around an object. These hooks can come in various shapes and sizes, depending on the specific use of the bungee cord.

Size and strength of bungee cords

Bungee cords come in various lengths and thicknesses, and the right size depends on what you’re using it for. Shorter bungee cords can be perfect for bundling small items, while longer cords can wrap around larger objects or span bigger distances. 

As for thickness, thicker cords can be ideal for heavier-duty tasks however the elasticity and density of the bungee cord core material and the properties of the outer sheath are the primary determinants of strength and durability.   A thinner, high-density core bungee cord can be far stronger than a thicker cord.

A bungee cord that works for you should be chosen so that it is capable of holding the weight of the load. Overstretching a bungee cord can lead to the cord breaking which can be dangerous. Generally, a safe working load is achieved at ⅔ or less of the fully extended cord.  It is worth noting that you should always ensure that you never stand in in the direct rebound path of a tensioned bungee cord.

Ways to Take Advantage of How Bungee Cords Work

Because of the adaptable nature of how bungee cords work, they’re able to be used in a wide range of situations. 

Securing Loads on Vehicles

This is one of the most common uses of bungee cords. They can be used to secure loads on the back of a ute, truck, or trailer, ensuring that items don’t move or fall off during transport. If you’re moving large items like mattresses or furniture, bungee cords can help secure these items to your vehicle.

Bungee cords are very useful in boating to secure equipment and prevent it from being lost overboard.

Camping and Outdoor Activities

Bungee cords are a camper’s best friend. They can be used to secure a tent to its pegs, attach camping gear to a backpack, or tie down items on a roof rack.

Bungee cords can be used in various DIY projects, such as creating a custom car roof rack or building a bike storage solution.

Gardening and Around Home

Bungee cords can be used to secure tarps over areas that need protection from weather or pests. Similar to when you want to cover a trailer with a tarp. They can also help bundle and carry branches or other yard waste.

Organising and Storing Items

In homes or workshops, bungee cords can be used to secure items in place, such as tools on a pegboard or sports equipment in a garage.

Figuring out how to clean a tarp first starts with determining what material your tarp is made of, then following a short set of steps to clean it. Tarps, short for tarpaulins, are versatile and durable covers used to protect a range of items from outdoor elements such as rain, sun, and wind. But, even though they’re used to keep your belongings clean and safe from the elements, sometimes they need a good clean too.

Regardless of the material of the tarp you have, it’s important to keep it clean and well-maintained. This will help it last as long as possible and perform its best.

Cleaning different materials of tarps

Tarps are made from a wide variety of materials. Each of which has a different purpose. Some of the most common materials of tarps include canvas, polyethylene, vinyl, and mesh. 

Spider Tarp offers a range of tarps in trailer covers, ute covers, and truck covers, made from different materials, each with its own unique benefits. Our tarps are made from tough, rip-resistant materials such as waterproof polyethylene (PE) coated fabrics for general domestic use, and heavyweight 600gsm (18oz) waterproof vinyl (PVC) coated fabrics featuring 50mm (2”) edge webbing for trade and industrial applications.

Will the type of material affect how to clean a tarp?

The type of material used in a tarp can change the cleaning process. For example, vinyl tarps are more durable and resistant to water, but they can be more challenging to clean than polyethylene tarps. Meanwhile, mesh tarps are breathable, making them great for airflow, but they can also collect debris more easily. 

Depending on the type of material you use, you may want to supply different equipment or use different cleaning methods. The below method on how to clean a tarp is an outline, that will be applicable to most common materials tarps are made of

The material tarps are made of can depend on their use and origin. Most commonly, tarps can be made from a variety of materials, including polyethylene, canvas and vinyl. Each tarp material has its own advantages and disadvantages, and it’s important to understand the properties of each before making a decision.

Tarps have been around for centuries and have been used for a variety of purposes, from protecting outdoor equipment to providing temporary shelter. With so many different types of tarps available on the market, it can be tough to figure out which one is best for your needs and why.

The backstory of tarps and what materials they're made of

Blue Pvc Tarp

The first material tarps may have been made of

The use of tarps can be traced back to ancient times when nomadic people used animal hides to cover their shelters and protect their belongings from the elements. Tarps as we know them today likely evolved from these early forms of shelter and protection.

More recently, in the late 19th and early 20th centuries, tarps were primarily made from canvas, a heavy-duty and durable material that was ideal as the use of tarps grew with industries such as construction, agriculture, and transportation expanded and needed reliable, low-cost solutions for protecting their equipment and materials

How the material tarps are made of changed

Then, in the mid-20th century, the advent of new synthetic materials such as polyethylene (PE) and polyvinyl chloride (PVC) led to the development of lighter and more affordable tarps. These new materials offered improved resistance to water, UV light, and other elements, making them ideal for a wide range of outdoor uses.

Today, because they’re more versatile and affordable than ever, tarps continue to be an essential tool in a variety of households and industries. And, with new advances in materials and manufacturing techniques leading to ever-more specialised tarps for specific uses and applications, such as ute tray covers, tarps are going to be a staple for a long time to come.

What material are tarps made of? Common materials used in tarps

Polyethylene material of tarp

Polyethylene (PE)

Polyethylene (PE) is a thermoplastic polymer made from the monomer ethylene . It is a versatile and widely used material that is commonly found in many consumer and industrial products such as:

  • Plastic bags, films, and packaging materials
  • Food storage containers
  • Water bottles
  • Automotive parts
  • Wires and cables

PE tarps are made from High-Density Polyethylene (HDPE) which is applied as lamination to each side of a fabric scrim.  PE tarp edges are typically heat-sealed or “welded” and often contain a synthetic cord in the hem to improve edge stiffness.

Advantages of this material of tarp

Polyethylene is one of the most commonly used materials for tarps because it is affordable, lightweight, and durable. This makes PE tarps ideal for a variety of outdoor applications, from covering outdoor equipment to providing temporary shelter. 

Disadvantages of this material of tarp

One of the disadvantages of polyethylene tarps is that they are not very breathable, which means that moisture can build up underneath the tarp. Additionally, polyethylene tarps tend to be lighter in weight and are more prone to tearing, which makes them less suitable for repetitive heavy-duty applications.

Green canvas material of tarp


Canvas is a durable and heavy-duty material that is commonly used in the manufacture of tarps. It is made from cotton or synthetic fibres that are woven into a tightly woven fabric. The tight weave of canvas makes it naturally water-resistant, while its breathable nature allows it to prevent condensation buildup. Canvas is commonly used in products like:

  • Tents and camping gear
  • Backpacks and duffel bags
  • Sail covers, boat covers, and boat tarps

Advantages of this material of tarp

Canvas tarps are known for their durability, breathability, and water resistance. This makes them ideal for outdoor applications where protection from the elements is important. Additionally, canvas tarps are known for their long-lasting qualities, which makes them a good investment for those who use tarps frequently.

Disadvantages of this material of tarp

One of the main disadvantages of canvas tarps is their weight. Canvas tarps are much heavier than PE and PVC  tarps, which makes them less suitable for applications where portability is important. Additionally, canvas tarps are more expensive than PE and PVC  tarps, which can make them less accessible to some consumers and can be prone to mould if not dried correctly.

Black tarp made from a vinyl material


Vinyl is a synthetic polymer made from polyvinyl chloride (PVC) resin. It is a versatile and durable material that is often used in making tarps, but it’s also used in the making of rainwear, pool covers, and even home flooring.

PVC tarps are made by spreading a thin layer of PVC on each side of a synthetic scrim.  The strength of the tarp is dependent on the thickness of the PVC layer and the density of the scrim. PVC tarp edges can be heat sealed in similar manner to PE tarps, but can also be sewn directly or with webbing for additional strength and durability.

Advantages of this material of tarp

Vinyl tarps are known for their waterproof qualities, making them ideal for applications where protection from the elements is essential. Additionally, vinyl tarps are durable and easy to clean, making them a good choice for those who use tarps frequently.

Disadvantages of this material of tarp

Like PE tarps,  solid vinyl tarps are not breathable, which can lead to moisture buildup underneath the tarp. Additionally, vinyl tarps can become brittle over time if not properly treated with UV protection, especially in extreme weather conditions.

Other materials and construction (e.g. mesh, cotton, etc.)

There are many other materials used in tarps such as cotton and synthetic fabrics. Each material has its own advantages and disadvantages, and it’s important to consider these when choosing a tarp. 

Mesh tarps are made from similar materials to solid tarps however they differ in being constructed from woven threads.  These tarps are relatively lightweight, flexible and breathable, making them ideal for outdoor applications, particularly involving light diffusion and where wind may be an issue. On the other hand, cotton tarps are durable and water-resistant, but they can be heavy and expensive. It’s important to consider your specific needs and the type of application you will be using the tarp for when making your decision.

Choosing material tarps for you

Choosing the best material for a tarp depends on the specific needs and requirements of the user. While canvas is known for its heavy-duty and durable nature, polyethylene is a versatile and widely used material that offers relatively low cost, durability and weather resistance. For repetitive heavier-use trade and industrial applications, vinyl may be more appropriate.

Transporting goods and materials in trailers can be tricky, but trailer covers make it a lot easier. Hook straps for trailer covers help to secure both the cover and the load, ensuring your trailer is safe.

What are hook straps for trailer covers?

Hook straps are a type of tie-down or fastening strap that feature hooks on either end. 

Hook straps, also known as tarp straps, are commonly used in combination with tarp trailer covers to protect the load from the elements and keep it secure during transit, serving a big part in the backbone of trailer cover security. 

A simple but effective design, these straps provide an effective mechanism for attaching the cover to a trailer by creating an adjustable fastening system that keeps it firmly in place. By doing so, they help trailer covers stay in place, preventing flapping and tearing while travelling.

As well as preventing any damage to the trailer cover itself, by holding everything in place, the load is also more secure, helping to prevent trailer loads from shifting, falling off, or getting damaged.

How do hook straps work?

Hook straps need to be a balance of both flexibility and durability. A little bit of give is necessary to prevent them from snapping, but strength is needed to hold a trailer cover and everything else in place.

Because of this, hook straps for trailer covers are typically made of durable and flexible materials, such as rubber, polypropylene, or nylon, and come in various lengths and widths to accommodate different load sizes and types of vehicles. 

The hooks on either end of the strap can be attached to the vehicle frame or other secure points, while the strap itself is tightened to secure the load. 

How to use hook straps

While simple in design, hook straps are efficiently and securely fastening your loads. Here’s a basic guide on how to use them:

  1. Inspect the Strap: Before using any hook strap, always inspect it for signs of wear, damage, or fraying. It’s essential to ensure the strap is in good condition to maintain optimal safety.

  2. Position the Load: Make sure the item or cover you’re securing is positioned correctly. This ensures a snug fit once the strap is tightened.

  3. Hook One End: Start by attaching one end of the strap to a secure point on your vehicle, trailer, or item. This could be a designated loop, an eyelet, or any sturdy anchor point.

  4. Stretch and Secure: Pull the strap across the item or cover you’re securing. Ensure it’s taut, but not over-stretched, to avoid damaging the strap or the item.

  5. Hook the Other End: Attach the other end of the hook strap to another secure point, ensuring it maintains tension across the load.

  6. Check Tension: Press down slightly on the secured item or cover. There should be minimal movement, indicating that the hook strap is doing its job. If there’s too much slack, you might need to readjust the strap for a tighter fit.

  7. Safety First: Never overload or overstretch the strap beyond its capacity. Always refer to the manufacturer’s guidelines regarding weight limits and optimal usage conditions.

Types of hook straps for trailer covers

Ratchet Straps

Ratchet Hook Strap

These are one of the most commonly used types of straps in Australia, especially when used to secure heavy loads. They feature a ratchet mechanism that allows users to tighten the strap to the desired tension, ensuring a secure hold.

Cam buckle straps

Cam Strap

Cam buckle straps are another popular option, featuring a cam-style buckle that allows you to easily adjust the tension of the strap. 

S-hook straps

Improved safety

Tarp straps make it easier to secure the cover or tarp to the trailer, allowing you to load and unload faster and more efficiently.

Improved safety

By keeping the load secure during transit, tarp straps can help to prevent accidents and spills that could result in damage or injury.

How to choose the right hook straps for trailer covers

Load weight and size

The weight and size of both the trailer and the load will determine the type and size of the tarp strap that you need. Make sure to choose straps that are rated for the weight of your load to ensure that they can handle the load safely.

Type of trailer

Consider the type of trailer you will be using the tarp straps on. Some trailers have specific attachment points, so make sure to choose straps that are compatible with your trailer.

Material quality

Look for tarp straps that are made of high-quality, durable materials, such as heavy-duty rubber or polypropylene, to ensure that they can handle the weight of the load and withstand the elements during transit.

Length and width

Consider the length and width of the straps you need. Choose straps that are long enough to reach from one attachment point to another, but not so long that they will get tangled or become a tripping hazard.

Breaking strength

Breaking strength refers to the amount of weight the strap can hold before breaking. Make sure to choose straps with a breaking strength that is greater than the weight of the load to ensure maximum safety.

Not sure how to choose the hook straps and trailer covers?

Hook straps for trailer covers are essential for securing loads to trailers and preventing them from shifting, falling off, or getting damaged during transit. To figure out the right hook straps for trailer covers, consider the weight and size of the load, as well as your trailer, and then decide which material and size are most suitable for it.

Do I need to Cover My Trailer Load?

According to the National Transport Commission and the Load Restraint Guide for Light Vehicles, 2018 edition, all loads that are hauled by truck, ute, or trailer must be adequately restrained. In all cases but the lightest loads, a tarp is normally not enough of a restraint to be relied upon by itself. 

However, in conjunction with other lashings, a strong trailer cover fastened with appropriate attachment cords is a great way to help not only keep the load secure and constrained but also to protect it from wind and inclement weather.

Some light loads might include garden waste, such as grass clippings, small branches, garden and household rubbish, or similar, that you are taking to the tip. The sides of your ute or trailer are typically enough to constrain the waste as long as it’s covered by a tarp. Another light load might be light building materials, which could include:

  • drywall
  • plasterboard
  • plastic pipes
  • other items that could be dislodged by the wind

A heavy-duty tarp will usually be enough to hold these materials in place. The same holds true for recreational items like camping gear, climbing gear, or equipment for the beach.

Remember, a tarp by itself will normally only suffice if the load is below the sides of the trailer. For items that protrude above the sides, additional lashings will be necessary, like Spider-Cords. Heavy and bulky items, such as refrigerators, desks and beds may need to be restrained by load-rated straps and lashings. 

How to Cover a Trailer with a Tarp

When tarping a trailer for transporting goods or camping, the first decision is to decide whether you want to use a fitted tarp or a flat tarp. Of course, fitted tarps must be chosen to match your utility trailer whereas a regular flat tarp needs to be must be adjusted to fit.

For a fitted tarp, you will need to determine the normal loading configuration of the trailer as the tarp is typically fastened to the trailer with multiple short fixed-length cords.  If your load is going to extend beyond the trailer side walls, then you need to account for that extra space when choosing a tarp of the correct size.

Flat tarps provide a flexible way to cover a large variety of loads.  They must be folded to fit the trailer, but they will work just as well as long as you’re careful about selecting an appropriate-sized tarp and its folding. 

Having a tarp that is the wrong size or that is incorrectly folded and secured could create dangerous results.  The tarp could foul in the wheels of the trailer if it’s too big, or part of the load could be dislodged from the trailer if it’s too small resulting in penalties under the Load Restraint Guide for Light Vehicles. When folding the tarp, it’s important to ensure that the folds face towards the rear of the trailer so that the wind flows smoothly over the tarp rather than catching in the fold and potentially causing billowing. 

Adjustable trailer covers with tightening straps and cords like Spider Tarp’s range can help in ensuring your load is safely secure with minimal effort and reliable results.

Grommets, D-ings and eyelets


When it comes to how to cover a trailer, the tying technique you will use depends on whether or not your tarp has dedicated connections like D-Ringsor eyelets. With these connections, it’s a simple matter of threading rope or using some other connection to secure the tarp to the trailer tie bars or securing points.

Most of the time, you will find heavy-duty tarp clips to be a workable alternative when you’re trying to figure out how to put a tarp on a trailer without these connections. But, it’s better to only use this method for lighter loads because the temporary option, no matter how strong, won’t be as secure as eyelets or D-Rings on a purpose-built trailer cover

In an emergency, such as when a tarp tears, it’s possible to place something nonabrasive and round into the folds of the tarp and close the tarp around it with rope or bungee cord. Such jury-rigging is unreliable and should only be used when there is no other alternative. If you’re transporting goods in a trailer and your cover has become damaged, your safest course of action is to pull over, assess the damage and readjust and secure the cover where possible.

Correct Loading Procedure When Covering a Trailer

The question of, “How to Cover a Trailer With a Tarp”, is only part of the equation. How you load the trailer is equally as important. Always put the heavy items on the bottom and the lighter items on top.

Be sure to spread the load evenly across the flat surface of the trailer. Load the heaviest of items over the wheels and axles and balance the load evenly across the flat space. Fasten the heaviest items with a separate set of straps or cords before attaching the tarp.

Finally, avoid overloading your trailer or allowing too much to overhang any side of the vehicle. If something doesn’t fit, then you’re going to need a bigger vehicle. If you have to, make multiple trips rather than trying to cram the load together for one trip. Your safety and the safety of those you share the road with are paramount in all cases.

Miscellaneous considerations when transporting in trailers

Don’t transport loose tools. Put them in toolboxes, and fasten them properly. When it comes to bigger tools like rakes and shovels, which won’t fit into a toolbox, you can use a heavy-duty tarp or cargo net instead. It’s often easier to transport garden refuse if you bag it than if you simply toss it into the trailer.
