Food Blister Packaging For plastic packaging Blister is a plastic processing technology, the main principle is to flatten the plastic hard sheet softened, the use of vacuum adsorption on the mold surface, after cooling molding, widely used in plastic packaging, lighting, advertising, decoration and other industries. Food blister packaging: the use of plastic technology to produce plastic products, and the corresponding equipment to the product of the general name of the package. Food blister packaging products include: blister, tray, plastic box, synonyms are: vacuum hood, blister and so on. The main advantage of food blister packaging is to save raw and auxiliary materials, light weight, easy to transport, good sealing performance, in line with the requirements of environmentally friendly green packaging; can be packaged any shaped products, packing without additional cushioning material; , Beautiful appearance, easy to sell, and suitable for mechanization, automated packaging, easy to modern management, saving manpower, improve efficiency Food blister packaging equipment mainly include: plastic molding machine, punch, sealing machine, high frequency machine, folding machine. Packaging the formation of packaging products can be divided into: card, suction card, double bubble shell, half bubble, folding bubble shell, three fold blister and so on. 1: mold making and processing: according to the requirements or sample specifications, the first to make a good plastic mold, under normal conditions, are the use of gypsum production of food blister packaging mold, but also useful wood carving and metal products for mold, plaster mold Well, let the natural dry completely dry or dry, and then according to the specific surface of the product convex and concave, with 1-2 mm drilling in the product does not affect the appearance of the package looks like a small hole in the hole, if it is a box Products, have to drill some holes in the surrounding, so that when the plastic production, the air can be drawn out, the mold drill hole, the gypsum mold must also be hardened, plus hardening method is concentrated alum saturated liquid Soak after drying. 2: mold processing After drying, the mold into the vacuum chamber on the upper iron plate, and then according to the size of the mold, the plastic sheet into the applicable size, and then the sheet into the heated cabinet, so that it is completely fixed , And then the cabinet with a plastic sheet on the thermostat furnace for softening treatment. 3: the softened plastic sheet together with the wooden cabinet, placed in the vacuum chamber, start the suction switch, the vacuum indoor air suction clean, until the plastic sheet cooling, that is, with the mold of the same concave packaging or process mold. 4: food blister packaging finishing; will produce the product trimming finishing is finished products, and then after packaging can be sold. First, PVC sheet toughness is high, not easy to burn, burning will produce chlorine, the environment caused a certain impact, PVC easy heat, can be used sealing machine and high frequency edge, is the production of transparent plastic products, the main raw material. PVC sheet is a widely used and popular materials, PVC film can be divided into two kinds of environmentally friendly and environmentally friendly, can be made transparent, color, anti-static, gold-plated, flocking and other blister packaging products, its It is widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and so on. It is widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery, etc. Product packaging. Second, PS hard chip low density, poor toughness, easy to burn, burning will produce styrene gas (a harmful gas), it is generally used to produce a variety of industrial plastic tray. PS sheet is now developed several years of new environmentally friendly plastic packaging materials, with its excellent thermoforming performance, good environmental performance and health performance, widely used in medicine, food, toys, electronics.
