1. High transparent low temperature heat sealing CPP
Typical structure: BOPP (printing) / CPP
Features: good transparency, low heat sealing temperature and fast bag making speed.
Main uses: Xizhilang, Robust and other famous brand jelly pudding packaging bags.
2. Aluminum grade CPP
The CPP can be plated with aluminum on one side and has good heat-sealability on the other side. It can be used as an aluminum-plastic composite packaging to save a layer of base material, reduce one-time compounding, and greatly reduce costs.
Typical structure: BOPP (printing) / CPP aluminized film Features: beautiful metallic luster and good heat sealability, suitable for automatic packaging.
Main uses: puffed food bags, cereal bags, etc.
3. The CPP cooking bag is made of a special PP material, which is not deformed under high temperature and high pressure and has elasticity.
Typical structure: PET / AL / 70μmCPP
PA / AL / 70μmCPP
Features: Large tensile strength, good heat resistance, and puncture resistance.
Main uses: Roast duck bags, roast chicken bags and other meat products, which require high temperature sterilization.
4. Cover material type CPP
Typical structure: PET (printing) / AL / CPP
PET (printing) CPP
Features: It has good thermal viscosity (especially initial viscosity) with PP matrix bottle (cup) and is easy to cut.
Main use: Add AL for yogurt bottle cap or oil bottle cap. The transparent type is mainly used for cup beverages and space water lids.
5. Refrigerated CPP
CPP is generally brittle at low temperature, and it is not suitable for refrigerated packaging. Recently, soft CPP has been developed and can be used at -18 ℃ refrigerated conditions.
Typical structure: BOPP / CPP
Features: CPP is not brittle at low temperature, and still maintains good sealing strength.
Main use: rice dumplings, dumplings, etc., which need to be refrigerated and must show transparency.
