Al:aluminum Foil aluminum foil, which we often call pure aluminum

Aluminum Foil Vacuum BagDivided into pure aluminum and aluminum plating, in the absence of printing, pure aluminum and aluminum plating is easy to distinguish, look at the sample office.

Generally speaking, aluminum foil bag, you have to according to what he said bag requirements to judge whether he said aluminum foil refers to pure aluminum or aluminum plating.

The thickness of pure aluminum is generally 0.007MM and 0.009MM, the most used is 0.007MM, if the guest said AL007 or AL7, then we know is pure aluminum

The thickness of PET aluminum plating is 0.012MM=12UM

The thickness of the CPP aluminum plating is 0.025MM=25UM

Aluminum plating is divided into PET aluminum plating and CPP aluminized. PET aluminized can only be placed in the middle of the bag, such as the bag is three layers of composite, that PET aluminum plating is placed on the second floor.

CPP Aluminum plating is placed in the innermost layer, because the CPP aluminized is as hot seal as the CPP, placed in the innermost layer, can be made into bags.

CPP aluminum plating is generally used to make toy bags, material combination: OPP+CPP aluminum plating or PET+CPP aluminum plating

Aluminum Foil Vacuum BagThe main printing materials are: OPP and PET, generally speaking, if the aluminum foil bag is printed, then this layer of printing material is either OPP, or PET.

Nylon, CPP and PE,PE milk White can also be printed, but not very good printing, printing effect is not very good.

The main composites are: CPP,CPP aluminized, PE,PE milk White-These are placed in the aluminum foil bag at the innermost layer of the

Generally placed in the aluminum foil bag middle layer of materials are: AL (pure aluminum), PET aluminum plating, PET, nylon
