Low-melt copolymerized polypropylene products are polypropylene products with excellent impact resistance and good processing fluidity. Due to their good surface stiffness and anti-scratch properties, they are not easy to crack due to environmental stress, thus widely used in crates, trays, paint buckets, and other fields.
1. High impact resistance, good surface stiffness, and anti-scratch characteristics;
2. No cracking problems caused by environmental stress.
Heavy packaging, crates, trays, trash cans, and other fields.
