The uses of OPP aluminized film are: the material used for vacuum food packaging bags, the vacuum aluminized film, and the food vacuum packaging bag can only be used if the plastic film with good barrier properties is compounded or aluminized.
BOPP (biaxially oriented polypropylene) vacuum aluminized film
Because BOPP film is divided into single-sided corona treatment film, double-sided corona treatment film and heat-sealable film, the performance and use after aluminum plating are different. Due to their poor oxygen barrier properties, they cannot Vacuum or steam packaging.
CPP (casting polypropylene) vacuum aluminized film
Vacuum aluminized CPP film can only be used as inner film material of composite packaging, not vacuum or cooking packaging. The shelf life of CPP vacuum aluminum plating film is 3~6 months. The corona treatment of over-preservation will subside and the adhesion of the aluminum layer will also be weakened. Special attention should be paid to moisture-proof during storage.
CPE (Casting Polyethylene) Vacuum Aluminized Film
Vacuum aluminized CPE film can be combined with glass fiber cloth to make ordinary sunshade 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. Be careful that the film stretching causes the aluminum layer to fall off.
CPVC (Unidirectional Stretch Polyvinyl Chloride) Vacuum Aluminized Film
Vacuum aluminized CPVC film can be printed on the aluminum layer, laser holographic printing or painted, and then used as candy twisted wrapping paper.
