The material of giant bags is usually polyethylene (PE) or polypropylene (PP).
Polyethylene (PE) is a common plastic material with good flexibility and wear resistance, suitable for making giant bags. Polyethylene can be divided into low-density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE), each of which has different physical and chemical properties and is suitable for different application scenarios.
Polypropylene (PP) is a relatively new plastic material with a weak chemical structure and easy molecular chain breakage, so it can be effectively degraded and is suitable for packaging materials that need to be degraded quickly. Non-woven bags are made of polypropylene and can be completely decomposed within 90 days, which is environmentally friendly.
