Pets Food Bag

At present, the frozen food packaging bags on the market can be mainly divided into single-layer packaging bags, composite packaging bags, and multi-layer co-extruded packaging bags. Composite soft plastic is widely used in frozen food packaging bags, and this type of frozen food packaging bags also has many combinations in material structure.

According to the material, there are several types that can be used for frozen food packaging. One, PET/PE. This material structure is more common in the packaging of quick-frozen food products. It has good moisture resistance, cold resistance, and low-temperature heat sealing performance, and the production cost is relatively low.

Second, BOPP/PE and BOPP/CPP. The frozen food packaging bags of these two structures have excellent moisture resistance and cold resistance, high low-temperature heat-sealing tensile strength, and good economy. It is worth mentioning that BOPP/PE material feels better than PET/PE, which is good for product marketing.

Third, PET/VMPET/CPE, BOPP/VMPET/CPE. Compared with single-layer and double-layer packaging bags, the three-layer structure is more firm and stable, and has high barrier performance. In addition, the existence of the aluminized layer also has a more prominent advantage in printing performance. However, compared with the above materials, low-temperature thermal Poor sealing performance and high cost Fourth, PA/PE, PET/PA/LLDPE, PET/PA/AL/PE, PA/PE. The structure of these four types of materials is more resistant to freezing and impact, and the PA layer ensures good puncture resistance. The disadvantage is that the production cost is high, and it is generally used for angular or heavy food product packaging.
