Blister: A plastic processing technology. The main principle is to heat and soften the flat plastic sheet, vacuum-adsorb it on the surface of the mold, and cool it to form. Blister packaging: a general term for the production of plastic products by the blister process and packaging of the products with the corresponding equipment. Blister packaging products include: blister, tray, plastic box, synonym: vacuum cover, blister and so on.
The main advantages of blister packaging are that it saves raw and auxiliary materials, is light in weight, convenient in transportation, good in sealing performance, and meets the requirements of environmentally friendly green packaging; it can package any shaped products, no additional buffering material is required for packing; the packaged products are transparent and visible. Beautiful appearance, easy to sell, and suitable for mechanization, automated packaging, easy modern management, saving manpower.
Blow molding: Also known as hollow blow molding, a rapidly developing method of plastic processing. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is heated (or heated to a softened state), placed in a split mold, and compressed air is introduced into the parison immediately after closing the mold to blow the plastic parison It is inflated and adhered to the inner wall of the mold, and is cooled and released to obtain various hollow products. With the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used.
