PP sheets are primarily made from polypropylene resin, with various process color masterbatches, impact modifiers, and light stabilizers added. They are manufactured through processes such as mixing, plasticizing extrusion, three-roll calendering, cooling, traction, and winding. PP sheets are characterized by being non-toxic, odorless, hygienic, having high mechanical strength, and excellent barrier properties. They are suitable for packaging in industries such as industrial, agricultural, and fruit sectors. PP anti-slip sheets processed into trays have smooth and aesthetically pleasing surfaces, which are well-received by users. PP sheets are also suitable for packaging high-cold-resistant frozen foods, such as ice cream boxes, dumpling boxes, and tangyuan boxes. Additionally, due to their excellent physical properties and environmental characteristics, PP sheets are widely used in medical supplies and electronic product packaging fields. Polypropylene resin, as a thermoplastic plastic, has good chemical stability and can resist various acids and alkalis, making PP sheets perform excellently in environments requiring long-term storage and transportation. Moreover, the recyclability of PP sheets meets modern environmental requirements, helping to reduce environmental pollution.
