Q32: Are the PP tarps currently available on the market the same as our products? What are the key differences between them and our products?

A: What is commonly referred to as “PP tarps” on the market falls into two categories, which have fundamental differences in manufacturing processes, product performance, and application scenarios—differences that customers often confuse: The first category—ordinary PP woven laminated tarps (color-striped tarps), which account for 90% of the market—uses a PP flat-yarn woven base fabric with a simple single- or double-sided lamination process. These tarps feature a distinct grid pattern on the surface, feel thin and somewhat stiff to the touch, and are prone to developing permanent creases when folded. Most products in this category contain recycled waste materials. After 1–2 years of outdoor use, they develop issues such as powdering, flaking, and brittleness. They are suitable only for simple applications such as short-term dust control at construction sites or temporary cargo covering. They cannot be hot-air welded, lack impermeability, and do not feature a long-term weather-resistant modification system; therefore, they are unsuitable for medium- to long-term outdoor projects or specialized operating conditions. The second category consists of Zhijie’s all-PP homogeneous, monolithic, modified engineering tarpaulins, which are high-end engineering-grade products. Manufactured using an extrusion-thermal lamination monolithic molding process, they feature a smooth, dense surface without any woven texture. Both the base fabric and the coating are made of homogeneous PP material, resulting in a compact fabric surface with excellent elasticity. The product supports integrated hot-air welding at 260–280°C and offers excellent impermeability and sealing performance. Its weather resistance, flame retardancy, and low-temperature protection properties can all be customized. It also features outstanding corrosion resistance and recyclability, making it widely suitable for medium- to long-term high-end engineering applications such as freight transport, animal husbandry, marine engineering, chemical containment, and large-scale membrane structures.
