1. BOPET (polyester) vacuum aluminized film
BOPET (polyester) film has high transparency and is a polar film with a stable surface tension above 45~50dyn, so the Aluminum mylar of BOPET aluminized film has good firmness. After aluminized, the brightness is higher than other aluminized films, and it will not be dealuminized after long-term storage (if it is not damp, the storage period can reach more than one year). It can be used as the surface layer or the middle layer of the substrate film of the composite flexible packaging, and it is the best aluminum-coated material for the middle layer of the composite flexible packaging. The electrical insulation performance of BOPET film is very good. After vacuum aluminum plating, it can be used as capacitance film of coiled capacitors. BOPET film has good gas barrier properties, not only gas barrier, but also good oxygen barrier and water vapor barrier. It can be used as a barrier layer for vacuum packaging or inflatable packaging bags. However, because the aluminum layer of the vacuum aluminized film will fall off after being damp, it is not suitable for use as a retort packaging bag.

2. BOPP (biaxially oriented polypropylene) vacuum aluminized film
Because BOPP films are divided into three types: single-sided corona-treated films, double-sided corona-treated films and heat-sealable films, the properties and uses after aluminum plating are different. Due to their poor oxygen barrier properties, they cannot be used. Do vacuum or retort packs.
3. CPP (cast polypropylene) vacuum aluminized film
Vacuum aluminized CPP film can only be used as the inner film material of composite packaging, and cannot be used for vacuum or retort packaging. The storage period of CPP vacuum aluminized film is 3 to 6 months, and the corona treatment will fade after extended storage, and the adhesion of the aluminum layer will also be weakened, so special attention should be paid to moisture-proof when storing.
4. CPE (cast polyethylene) vacuum aluminized film
Vacuum aluminized CPE film can be combined with glass fiber cloth to make ordinary sunshade tarpaulin packaging. The brightness and adhesion of the aluminum layer of the CPE vacuum aluminized film itself are poor, and the storage time is also short. Pay more attention to tension control when rewinding, and be careful that the aluminum layer will fall off due to film stretching.
5. CPVC (Uniaxially stretched polyvinyl chloride) vacuum aluminized film
Vacuum aluminized CPVC film can be printed on the aluminum layer, laser holographic printed or painted, and can be used as twist wrapping paper for candies.
