|The processing of polyethylene blow molding, extrusion, injection molding available methods, widely used in the manufacture of thin film, hollow fiber and other products, daily-use sundry goods.
Process method: the transfer method. The aluminum coating is formed by transferring the metal aluminum layer to the surface of the substrate by the carrier film (vacuum aluminum plating film). The transfer process is a new technology developed on the basis of direct evaporation method. It overcomes the limitation of direct evaporation method for substrate, especially for aluminum and paper coating on plastic and all kinds of paper and paperboard. The transfer method has been applied to the aluminized products of cloth, fiber, leather and other substrates. Our country mainly uses the transfer method to produce aluminum plating paper. 
The process flow of aluminum plating film production:
Coiling of substrate, vacuum pumping, heating evaporation boat, aluminum wire feeding, evaporation, cooling, thickness measurement, flatting and rewinding
|Metallic bubble mailers
Metallic bubble mailers is made of low density polyethylene (LDPE). The features of low cost, large volume, good waterproof performance. Usually we receive the courier package, the package outside the black or gray bag is the courier bag. LDPE film flexibility, are not easy to be torn, comparison of bright color printing, many logistics companies in order to achieve the effect of publicity will custom printed graphic courier bags. Express bag also has anti theft special self-adhesive tape, the self-adhesive posts with a one-time, non recovery characteristics and prevent the parcel before delivery to the recipient is opened without authorization, using a very simple and convenient.
Metallic bubble mailers has self-adhesive tape, using a special glue, as long as mouth closed, then open it will damage opening or a mark was opened, which is prevention in parcel transport process is stolen. At the same time the bag is closed, the sealing property is good, effectively waterproof, sunscreen.
The 1 layer is made of pure low density polyethylene film.
Metallic bubble mailers use high quality low density polyethylene material by blow molding equipment to produce Poly film, then composite with self-adhesive tapes. Finally, making equipment produce finished bag.
The blow molding process, composite process, bag making process
Thickness of 11 wire size can be customized
1 light weight, large volume.
2 strong flexibility, not easy to be torn
