Frozen food is an essential type of food for fast -paced life. Therefore, how to use food vacuum bags to keep fresh food in low temperatures need to do more in -depth research. The following food vacuum bag manufacturers will introduce the characteristics of several materials of food vacuum bag products:
1. BOPP/PE and BOPP/CPP. These two structured frozen food packaging bags are moisture -proof, have excellent cold resistance, low -temperature thermal sealing tensile strength, and good economy. It is worth mentioning that the BOPP/PE material is better than PET/PE, which is conducive to product marketing.
2. PA/PE, PET/PA/LLDPE, PET/PA/AL/PE, PA/PE. These four types of materials are more resistant to frozen and impact. In addition, the PA layer ensures good puncture resistance. The defect is that the production cost is high, and it is generally used for the packaging of edges or more food products.
3. PET/VMpet/CPE, Bopp/VMpet/CPE. The packaging bags of the three -layer structure are more firm and stable than a single layer and double -layer, with high blocking performance, and the presence of the aluminum -plated layer makes the printing performance more prominent. However, compared to the above materials, low temperature and heat The sealing performance is slightly worse, the cost is high
4. PET/PE. This material structure is more common in the packaging of quick -frozen food products. It has good moisture, cold resistance, and low temperature heat sealing performance, and the production cost is relatively low.
