How to choose PU coated Fabric for Backpack?

pu coated fabric
PU coated fabric for backpacks refers to a type of fabric that has been treated with a polyurethane (PU) coating on one or both sides. This coating provides enhanced properties such as increased durability, water resistance, and weatherproofing. The PU coating forms a protective layer over the base fabric, creating a barrier that prevents water from penetrating the material and reaching the contents of the backpack. PU coated fabrics are commonly used in backpack manufacturing due to their ability to withstand rugged conditions, making them suitable for outdoor activities, travel, and everyday use. The PU coating also adds strength to the fabric, increasing its resistance to abrasion and tearing. Overall, PU coated fabric for backpacks offers a combination of durability, water resistance, and performance, making it a popular choice in the production of high-quality backpacks.

PU coated Oxford fabric is a type of textile material commonly used in the manufacturing of backpacks. It is made by applying a layer of polyurethane (PU) coating to Oxford fabric. The PU coating enhances the fabric’s performance by adding desirable properties such as water resistance, durability, and flexibility. This makes PU coated Oxford fabric an ideal choice for backpacks designed to withstand various environmental conditions.


The base fabric used in PU coated Oxford fabrics is often made from a polyester or nylon material. Oxford fabric is known for its strength, durability, and abrasion resistance, making it suitable for backpacks and characterized by its unique basket weave structure, which consists of a plain weave pattern with a heavier, coarser yarn in one direction and a finer yarn in the other direction. This weave structure contributes to the fabric’s strength and adds a distinctive texture.The PU coating is applied to the surface of the Oxford fabric to provide additional properties and performance enhancements. It is a thin layer of polyurethane material that adheres to the fabric and enhances the fabric’s resistance to abrasion, tearing, and general wear and tear, increasing the longevity and durability of the backpack.

Factors to Consider When Choosing PU coated Fabric for Backpack

Durability and Strength

One of the key factors to consider when selecting PU coated fabric for backpacks is its durability and strength. Look for fabrics that are known for their robustness and ability to withstand daily use, rough handling, and potential wear and tear. The fabric should be able to endure the weight of the contents and any external impacts without easily tearing or showing signs of damage.

Water Resistance and Weatherproofing

Another crucial aspect to consider is the water resistance and weatherproofing capabilities of the PU coated fabric. Backpacks are often exposed to various weather conditions, including rain, snow, and humidity. Ensure that the fabric has a reliable PU coating that effectively repels water, keeping the contents dry and protected. Look for fabrics that have undergone proper testing and have a high level of water resistance.


Breathability and Comfort

While water resistance is important, it is equally crucial to consider the breathability and comfort of the PU coated fabric. Backpacks are worn for extended periods, and a fabric that allows moisture and heat to escape will help prevent discomfort and sweating. Look for fabrics that strike a balance between water resistance and breathability, ensuring a comfortable carrying experience.
