This is a 50-220L chemical barrel filling machine that can produce three-layer products. LLDPE stands for linear low-density polyethylene, and its application range in chemical plastic barrels is relatively wide. Compared with HDPE, LLDPE has a lower density and stronger ductility, so it can better withstand impact and has higher shock resistance. Common uses include: storage and transportation of liquid chemicals, and packaging of materials in the fields of food, medicine and cosmetics. PP stands for polypropylene, which has excellent chemical corrosion resistance and permeability resistance, low water absorption, and can be used for packaging of chemicals such as acids and alkalis. However, it should be noted that it has low rigidity and is easy to deform, so it needs to be protected during transportation and stacking. In summary, the choice of material for chemical plastic barrels should be based on the actual use scenario. Different materials have different characterist…
