Many customers who are customizing plastic packaging bags for the first time do not understand the material of plastic packaging bags. What are the advantages of these plastic packaging bag materials? Below is an analysis of biaxially oriented polypropylene BOPP: high transparency, tensile resistance, cold resistance, heat resistance, -40 ° C-120 ° C; Biaxially oriented polypropylene extinction film: a thin film with low reflectivity, semi transparent shape, and extinction effect.
Cast polypropylene CPP: with good gloss, transparency, and heat sealing properties, cast high-temperature film is suitable for steaming and cooking packaging; Polyethylene PE: transparent, good gloss, heat sealable, cold resistant; Polyester film PET. It has tensile strength, heat resistance of 60-150 degrees, good air tightness, suitable for boiling, and no heat sealing,
Nylon PA or NY: colorless, high transparency, cold resistant, heat-resistant, oil resistant, and can be steamed. Easy to absorb moisture, without heat sealing properties. When customizing plastic packaging bags, it should be noted that plastic packaging bags are all composed of the above individual materials, such as OPP composite CPP. This combination is very suitable for packaging some small foods. Its main characteristics are high brightness, good transparency, exquisite printing, moisture resistance, and oxygen barrier.
