Blister: A plastic processing technology, the primary principle of which is to heat and soften a flat plastic hard sheet, and then use vacuum adsorption to attach it to the surface of the mold. After cooling, it is formed. Blister packaging: a general term for the production of plastic products using vacuum forming technology and the packaging of the products with corresponding equipment. Blister packaging products include: blister, tray, blister box, synonymous with: vacuum hood, blister, etc.

The primary advantages of vacuum packaging are saving raw materials, being lightweight, easy to transport, having good sealing performance, and meeting the requirements of environmentally friendly green packaging; Can package any shaped product without the need for additional cushioning materials during packaging; The packaged product is transparent and visible, with a beautiful appearance, easy to sell, and suitable for mechanized and automated packaging, which facilitates modern management and saves manpower.

Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The tubular plastic preform obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while it is hot (or heated to a softened state). After closing the mold, compressed air is immediately introduced into the preform to inflate it and tightly adhere to the inner wall of the mold. After cooling and demolding, various hollow products are obtained. With the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely applied.
