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 brand-name jelly pudding bags.
2. Aluminized CPP
The CPP can be plated on one side and has good heat sealability on the other side. As an aluminum-plastic composite package, it can save a layer of substrate, reduce the compounding once, and greatly reduce the cost.
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 and elastic under high temperature and high pressure.
Typical structure: PET/AL/70μm CPP
PA/AL/70μmCPP
Features: high tensile strength, good heat resistance, puncture resistance.
Main use: packaging of meat products such as roast duck bags and roast chicken bags, requiring high temperature sterilization.
4. Cover type CPP
Typical structure: PET (printing) / AL / CPP
PET (printing) CPP
Features: Good thermal adhesion (especially initial tack) to PP base bottles (cups) and easy to cut.
Main use: Add AL for yogurt bottle cap or oil bottle cap. The transparent type is mainly used for cup drinks and space cup lids.
5. Refrigerated CPP
CPP is generally low-temperature brittle and should not be used in refrigerated packaging. Recently, soft CPP has been developed and can be used in -18 ° C refrigeration conditions.
Typical structure: BOPP/CPP
Features: CPP is not brittle at low temperatures and still maintains good sealing strength.
Main uses: dumplings, dumplings, etc., which need to be refrigerated and show transparency.
