A: Product identification can be performed using three visual methods, and on-site demonstrations are highly credible: 1. Visual inspection: Ordinary PP tarps have a distinct woven mesh pattern on their surface; our engineering-grade PP tarps have a smooth, dense surface with no woven pores. 2. Installation Performance: Standard PP tarps cannot withstand the high temperatures of hot-air welding and are prone to melting and tearing when heated; our products can be fused into a single piece at high temperatures, resulting in strong, watertight seams that prevent leakage. 3. Recycling Value: Standard woven tarps contain mixed materials and cannot be effectively recycled; our products are made entirely of homogeneous PP material, which can be directly shredded, pelletized, and recycled, offering high recycling value and outstanding environmental benefits.
