The blister packaging of the automatic blister packaging machine is a general term for the plastic products produced by the blister process and packaged with the corresponding equipment. Blister products mainly use high-quality flocking, PVC, PET, PP, PS, GAG and other plastic materials to produce high-grade and various specifications of blister packaging for electronics, stationery, toys, hardware, food, daily Packaging for gifts, handicrafts, etc.

　　1. Basic concept of plastic packaging

　　Products mainly include: blisters, trays, blister boxes, synonyms are: vacuum cover, blister, etc.

　　Blister packaging equipment mainly includes: Blister packaging machine, Blister forming machine, punching machine, sealing machine, high frequency machine, folding machine.

　　The packaging products formed by encapsulation can be divided into: insert card, suction card, double blister, half blister, half-fold blister, three-fold blister, etc.

　　The raw materials of blister packaging mainly include: PVC, PS, PP, PET, PETG and flocking, antistatic, conductive and other materials.

　　2. Blister packaging machine production process

　　Mold making and processing

　　According to the requirements or sample specifications, first make the blister mold. Under normal conditions, plaster is used to make blister packaging molds, but wood carving and metal carving products are also used as molds. After the gypsum mold is made, let it dry naturally or completely, and then use 1-2mm drills to drill many small holes in the depressions that do not affect the appearance of the product packaging according to the specific situation of the product surface.

　　If it is a product such as a packaging box, it is necessary to drill some small holes around the periphery so that the air can be drawn out during plastic production. After the mold is drilled, the plaster mold must be hardened. Hardening treatment method It is soaked in concentrated alum saturated solution and then dried.

　　After the mold treatment is completely dried, put the mold into the upper iron plate of the vacuum chamber, then load the plastic sheet into the applicable specification according to the size of the mold, and then put the sheet into the heating wooden cabinet to make it completely fixed, and then Put the wooden cabinet together with the plastic sheet on the constant temperature furnace for softening treatment.

　　Put the softened plastic sheet together with the wooden cabinet in the vacuum chamber, turn on the suction switch to suck the air in the vacuum chamber, and after the plastic sheet is cooled, you can get the same concave packaging or craft mold as the mold.

　　Blister packaging and finishing: Trimming and sorting the produced products is the finished product, which can be sold after packaging.
