  1. BOPP:ย Itย hasย goodย printingย performance,ย highย transparency,ย tensileย resistance,ย coldย resistance,ย heatย resistance,ย –ย 40ย โ„ƒย –ย 120ย โ„ƒ;
  2. PET:ย withย goodย printabilityย andย tensileย resistance,ย heatย resistanceย ofย 60-150ย degrees,ย goodย airย tightness,ย suitableย forย cooking,ย noย heatย sealing;
  3. CPP: It has good luster, good transparency, good heat sealing, and is widely used. However, CPP is not cold-resistant and will become brittle under low-temperature environments. In addition, CPP cast high-temperature film is suitable for cooking and packaging;
  4. PE: transparent, good luster, heat sealing, cold resistance. It can also be processed into various functional films as required, with many functions.
  5. Nylon PA: colorless, transparent, and soft than BOPP, cold resistant, heat resistant, oil resistant, and can be cooked. It is easy to absorb moisture and has no heat sealing property;
  6. Aluminum foil: It has the advantages of being moisture-proof, airtight, shading, abrasion resistant, fragrance protection, non-toxic and tasteless. After the aluminum foil is compounded with plastic and paper, the shielding property of aluminum foil is integrated with the strength of paper and the thermal sealing property of plastic, which further improves the shielding property of water vapor, air, ultraviolet light, and bacteria necessary for packaging materials. The use of aluminum foil packaging materials can ensure that food will not deteriorate for at least one year.
