Here is a comprehensive guide to polyethylene tarpaulin, also known as a poly tarp, including its types and applications.
A type of tarpaulin called polyethylene tarpaulin, also known as a poly tarp, is made of sheets of the same material that are laminated and bonded with woven polyethylene plastic strips to create a strong and resilient material.
In this blog, we’ll explore Poly tarpaulins. Please keep reading.
What is Poly Tarpaulin?
Instead of being a traditional fabric, polyethylene tarpaulin (Polycarp) is a laminate made of woven and sheet materials. Polyethylene plastic strips are loosely woven into the center, and sheets of the same material adhere to the top. This produces a material that resembles fabric and is waterproof as well as having good stretching resistance in all directions.
Low-density polyethylene (LDPE) and high-density polyethylene (HDPE) are both acceptable materials for sheets. These tarpaulins can withstand the elements for years if treated against ultraviolet light, but non-UV-treated material will quickly deteriorate and lose its strength and water resistance if exposed to sunlight.
Types of Poly Tarpaulin
There are different types of poly tarps in the market. Here are just a few.
Blue Poly Tarps
- The most common type of polyethylene tarp is blue.
- The edges are reinforced with polypropylene rope and heat-sealed, making them waterproof.
- Aluminum grommets every six feet are installed in these blue plastic tarps, allowing for precise tie-downs.
- Our Blue poly tarps can cover boats and outdoor equipment
- Not just this but poly tarps are protecting the farm as well.
- Hay tarps are made specifically to cover and shield hay fields.
- These hay tarps can be used to cover bales or stacks of hay and other grass crops, shielding them from pests, moisture damage, and weather damage.
- Hay tarps are silver on top to deflect harmful UV rays.
- Shade tarps are used to provide shadings, such as in outdoor tents and other structures, as their name suggests.
Clear Poly Tarp and White Poly Tarps
- These poly tarp types are heavy-duty and used in many industrial needs.
Here are the other types of tarpaulins:
How is Polyethylene Tarpaulin Made?
Polyethylene pellets are the most common starting point for tarpaulin manufacturers. HDPE pellets are fed into an extruding line, which melts the pellets to create polyethylene film, then cuts and stretches the film to create polyethylene yarn.
The yarn is then cross-woven on a weaving loom to create a fabric that is resistant to stretching and tearing. Low-density polyethylene (LDPE) is then applied to both sides of this fabric to give it a protective shiny finish. At this stage, masterbatches are used to choose the tarpaulin’s color.
When finished, the rolls of tarpaulin produced in this manner would be cut to size, their edges reinforced with rope and welded, and their grommets (the rings evenly spaced along a tarp’s edges) added.
Guide to Using Poly Tarps
Light-duty, medium-duty, and heavy-duty tarps are available; each grade is appropriate for a variety of uses. Since Tarpaulin is a highly versatile fabric, there are many uses of the product in everyday life:
- to cover outdoor machinery and vehicles in order to keep them dry and free of debris such as snow, rain, and sand.
- As a groundsheet or rainproof cover when camping
- In scaffolding to protect work areas from weather damage
- To store lumber or a protective liner for rail cars and trucks
- As a picnic mat or sheet for hauling yard debris such as leaves or trimmings
- In emergency situations such as to cover a broken window or damaged roof
- As a makeshift shelter for disaster relief
Qualities of a Poly Tarp
Polyethylene sheets and woven polyethylene strips that have been adhered to the surface make up poly tarps. A poly tarp won’t stretch or rip easily with this mixture. Additionally treated to block ultraviolet rays are poly tarps. The tarp can endure the sun for longer thanks to UV treatment.
Remember that even with UV. treatment, the service life of a tarp will depend on the area where it is used. The lifespan of the tarp will decrease with increasing temperature. The northern regions of the USA and Canada are where poly tarps can last longer. The life expectancy is a little bit shorter in hotter places like Arizona, Florida, Southern California, and Texas.
Polyethylene tarps are arctic flexible. When exposed to freezing conditions, these covers can still bend and do their jobs well. Due to the waterproof nature of poly tarps, the object they cover will remain dry in both rain and snow.
Conclusion: Poly Tarpaulins
Up until a better material is discovered, polyethylene tarpaulin has proven to be the most effective in many areas.
Folding and storing the poly tarps is simple. They can be kept with ease in garages, storage bins, supply closets, cars, boats, and any other location that has room for them. They are portable and very durable. It’s a great feature because it lets you use them repeatedly without worrying about ruining them or having them torn or ripped.
Which is Better Vinyl Or Poly Tarp?
Vinyl tarps are of much higher quality than poly tarps. They are strong enough for industry because they are designed to withstand harsh outdoor environments. This enables a high level of protection by providing resistance to environmental factors like water, oil, grease, acid, and mildew.
Is a Poly Tarp Waterproof?
Most poly tarps are waterproof. Waterproofing comes naturally to the polyethylene laminated film layers. Some poly screen tarps, however, are not waterproof and are only intended to be used as truck bed covers and sunscreens.
