PET/frozen PE,
the material structure is more common in quick-frozen food product packaging, moisture-proof, cold resistance, and it has a good low-temperature heat-sealing performance. Besides,the production cost is relatively low for food grade material.
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 it is more economical. It is worth mentioning that the material of BOPP/PE is better than that of PET/ PE feels good and is good for product marketing.
PET/VMPET/CPE, BOPP/VMPET/CPE,
three-layer packaging bag, double layer is more firm and stable, high barrier performance, and the existence of aluminum plating makes it have more outstanding advantages in printing performance, However, compared with the above materials, the low temperature heat sealing performance is slightly worse and the cost is higher.
PA/PE, PET/PA/LLDPE, PET/PA/AL/PE
these three types of material structures are more resistant to freezing and impact, thanks to the good puncture resistance of the PA layer. The defect is the production cost Higher, generally used for angular or heavy food product packaging. However, this material structure is also the most common and popular material.
