PVDC (polyvinylidene chloride) has high barrier properties, is not easily affected by ambient temperature, and has stable performance, and is not easily corroded by acids, alkalis and common organic solvents. 2.PE (polyethylene) has excellent gas barrier, oil barrier and aroma retention, which is helpful for the moisture retention of food. Moreover, PE has good plasticity and is not easily deformed and damaged as a packaging material. 3. PP (polypropylene) material is transparent and has good gloss. It is easy to process, has high tear resistance, high impact strength, water resistance, moisture resistance and high temperature resistance. 4.PA (Nylon) is tough, wear-resistant, oil-resistant, has good mechanical properties and toughness! It has good puncture resistance and certain anti-mildew and antibacterial effects, which can safely and effectively guarantee the shelf life of products. Vacuum packaging bags 5. EVOH (ethylene/vinyl alcohol copolymer) has good transparency and gloss, and can be used as high-quality transparent packaging.
