The difference between PVC tarpaulin and TPU fabric

How to choose the suitable fabric for waterproof bags

When it comes to choosing the right material for waterproof dry bags, PVC tarpaulin and TPU fabric are two common options. While they may look similar, there are some key differences between the two.

PVC (polyvinyl chloride) tarpaulin is a heavy-duty material that is widely used in the production of  dry bags, outdoor covers, tents, and tarps. Its strong vinyl coating makes it resistant to water, UV rays, and abrasions, making it ideal for long-term outdoor use. PVC tarpaulin is also easy to clean and maintain, making it a cost-effective option for many businesses.

TPU (thermoplastic polyurethane) fabric, on the other hand, is a newer material that has become increasingly popular in recent years. This fabric is made by laminating a layer of TPU to a polyester base material. TPU fabric is known for its high tensile strength, tear resistance, and flexibility. It's also very suitable for waterproof bags.

In terms of durability, both materials are very strong and can withstand harsh weather conditions. However, PVC tarpaulin is more susceptible to cracking and fading over time, especially when exposed to intense sunlight. TPU fabric, on the other hand, maintains its color and flexibility much better and is often used in applications where long-term performance is critical.

Another difference between PVC tarpaulin and TPU fabric is their environmental impact. PVC is a type of plastic that can release toxic chemicals during the manufacturing process and when it is burned. In contrast, TPU fabric is considered to be a more environmentally friendly alternative since it is made from non-toxic materials and can be recycled.

Overall, the choice between PVC tarpaulin and TPU fabric depends on the specific needs of your application. If you need a cost-effective option for short-term outdoor use, PVC tarpaulin may be the way to go. However, if you require a more durable and flexible material that can stand up to harsh environmental conditions, TPU fabric may be the better choice.
