What are the materials of vacuum packaging bags for frozen food? What are the characteristics of each?

At present, the main frozen food packaging bags on the market can be divided into single-layer, composite, and multi-layer co extrusion. Among them, composite soft plastic is a widely used type in frozen food packaging bags. And there are also various types of materials and structures for this vacuum packaging bag. What are the materials for frozen food vacuum packaging bags? What are the characteristics of each?

1 PET/PE， It is more common in frozen food products, with good moisture resistance, cold resistance, low-temperature heat sealing and other properties, and a lower price.

2. BOPP/PE and BOPP/CPP have high tensile strength for moisture-proof, cold resistant, and low-temperature heat sealing, high economy, and good hand feel.

3 PET/VMPET/CPE、BOPP/VMPET/CPE， Compared to single-layer and double-layer materials, this type of material is sturdy, stable, and has high barrier performance. Coupled with an aluminum plating layer, it also has a prominent advantage in printing performance. However, the low-temperature heat sealing performance of this type of product is slightly inferior and the cost is higher.

4 PA/PE、PET/PA/LLDPE、PET/PA/AL/PE、PA/PE， These four types of material structures are more resistant to freezing and impact, and with the addition of a PA layer, they have good puncture resistance. However, they have a higher cost and are suitable for packaging food products with sharp edges or heavier weight.
