Blister is a plastic processing technology, the main principle is the spread of plastic hard sheet heating softened, the use of vacuum adsorption on the mold surface, cooling after forming, widely used in plastic packaging, lighting, advertising, decoration and other industries.
Blister Packaging: The use of blister technology to produce plastic products, and the corresponding equipment to the product packaging collectively. Blister packaging products mainly include: blister, pallet, blister box, synonyms also: vacuum cover, bubble cover and so on. Blister packaging equipment mainly include: blister molding machine, punch, sealing machine, high-frequency machine, Folding machine. Packaging products can be divided into: card, suction card, double bubble shell, half bubble shell, folded bubble shell, 30 percent bubble shell and so on.
Bubble Shell: The use of blister technology will be transparent plastic hard sheet made of a specific convex shape of transparent plastic, covering the surface of the product, to protect and beautify the role of products. Also known as Bubble hood, vacuum cover, plastic mask. According to the form of shell different, but also can be divided into: Single bubble shell, double bubble shell, card shell and blister shell
Blister box: is a kind of cap and bottom of the blister products, the bottom and the lid connected together are called fold blister box, the bottom and the lid is called the sky Bottom cover blister box.
Blister pallet: Also called plastic Neto, the use of blister technology will be made of plastic hard pieces into a specific groove of plastic, the product in the groove, to protect and beautify the role of products.
Flocking Neto: is a special material of the blister pallet, will be ordinary plastic hard piece of the surface of a layer of velvet material, so that the surface of the pallet has a velvet feel, used to improve the quality of packaging.
Antistatic Pallet: is a special material of the blister pallet, the surface of the material resistance value of less than 10 of the 11-square ohms. Mainly used in electronics, it products blister pallet.
Blister Mold: Blister molding production with the mold, the lowest cost is gypsum mold, followed by electroplating copper, the most expensive is aluminum mold. Mold Drilling has a small hole, used for vacuum adsorption heating of the hard film, forming a blister products.
Blister forming: We often talk about blister, the use of blister molding machine will be heated and softened plastic hard plate adsorbed on the mold surface, cooling, forming a concave-convex shape of plastic.
Blister cutting: Plastic products after blister molding, after punching machine, will be large sheet of pieces of cutting knife into a single product. Also called blanking, cutting, die-cutting and so on.
Folding Edge: Blister packaging has a kind of call card packaging, you need to bubble shell three sides with folding machine folded to the back, so that in the next package process, the paper card into the folded edge, forming a card package.
Pull lines: Some of the unwanted line bumps (not on the mold) that are produced during the blister forming process need to be modified (to reduce the height and increase the slide degree) and to add additional pressure molds (which we call the upper mold) to solve. When the pull line is too large, is regarded as defective, can not be used for high-grade blister packaging, but in the field of parts turnover pallet, as long as the line line neat, does not affect the use of functions, should be considered as qualified products. Pull line also called: La Chu, cramps and so on.
Scratches: Blister finished products, especially transparent foam shell with scratches on the traces, if the traces too long, too large, bubble shell has become defective, can not be used for high-end packaging.
Crystal Point: In the process of blister sheet production, because of the fine dust in the air, dropped on the heating of plastic materials, resulting in a transparent flaw, especially in the transparent blister sheet production process, this defect is too large, too much, as defective.
Bubble: In the process of blister sheet production, because of the heating of the plastic material contains air, so that the production of finished sheet with bubbles, especially in the transparent blister sheet production process, this bubble too large, too much, as a defective.
Water Ripple: In the blister sheet production process, because of materials and processing technology, so that the production of finished sheet metal surface ripple, especially in the transparent blister sheet production process, this water ripple too large, too much, as a defective. Under normal circumstances, the thicker the sheet, the more obvious the water ripple. Qualified pet materials rarely have water ripple, but most PVC has water ripple phenomenon exists.
Heat sealing: is a blister packaging process, with the sealing machine will be coated with blister oil on the surface of the paper card and bubble shell heat together, forming a suction card packaging.
High-frequency sealing: is a blister packaging process, with high-frequency machine to produce high-frequency, the bubble shell and shell bonded between, forming a double bubble shell packaging.
Ultrasonic sealing: is a blister packaging process, the use of ultrasonic machines to produce ultrasonic, the bubble shell and shell bonding together, forming a double bubble shell packaging, and high-frequency sealing is different, ultrasonic not only can be sealed PVC, PETG materials, but also sealing pet materials, and packaging products do not have electromagnetic damage, particularly suitable for electronic packaging; The disadvantage is that the ultrasonic sealing edge can only be the point of the interval, and is usually only cover at a time straight edge.
