The reason why food blister packaging products sell well is what is set

Blister introduction


          Blister: A plastic processing technology. The main principle is to heat and soften the flat plastic sheet. It is vacuum-adsorbed on the surface of the mold and cooled to form. It is widely used in plastic packaging, lighting, advertising, decoration and other industries.


          Food blister packaging: a general term for the production of plastic products by blistering process and packaging of the products with corresponding equipment. Blister packaging products mainly include: blister, tray, plastic box, synonym: vacuum cover, blister and so on. Blister packaging equipment mainly includes: plastic molding machine, punching machine, sealing machine, high frequency machine, folding machine. The packaged products formed by the package can be divided into: card, suction card, double bubble shell, half bulb shell, double folded bulb shell, three fold bulb shell and the like.


          Bubble shell: The transparent plastic hard sheet is made into a transparent plastic with a specific convex shape by a blister process, and covers the surface of the product to protect and beautify the product. Also known as blister, vacuum cover


          Tray: Also called plastic inner support, plastic plastic sheet is made into plastic with specific groove by blister process, and the product is placed in the groove to protect and beautify the product.


          Flocking inner support: It is a blister tray with special materials. The surface of the ordinary plastic hard sheet is glued with a layer of velvet material, so that the surface of the tray has a velvety feel, which is used to improve the grade of the package.


          Antistatic tray: It is a plastic tray with special material. The surface resistance of this material is less than 10 11 ohms. Mainly used for plastic trays for electronic and IT products.


          Food blister packaging boxes are generally produced from PP materials, but according to customer requirements and product characteristics. The choice of PP materials is also diverse, because PP materials are also divided into PP color, PP color transparent, PP high transparent material, and PP color material. The characteristics of the products produced by each type of PP material are different and the uses are different. The following is a brief explanation of the characteristics and uses of the blister packaging boxes for the production of each PP material.



          The general characteristics of the natural PP material can only be resistant to low temperature, so the product can be refrigerated, generally used in supermarket meat, cooked food packaging, the color can be PP white, or PP other colors green, red can be.



          PP color transparent material, we also call translucent PP material, the characteristics of this material have high temperature and low temperature resistance, but low temperature and high temperature resistance are not very good. Therefore, we can only do some products that are not very strict with low temperature and high temperature resistance. They are generally used for factory dumplings, dumplings, and dumplings. This product can not be placed in the high temperature processing of micro boilers.



          PP high transparent material, this PP material is best for low temperature and high temperature resistance, and can also be sealed, and the price of this material is also the highest. Therefore, some products need high temperature resistance and low temperature resistance. We generally use high transparent PP materials to produce products. The products produced by this PP material are not problematic in high temperature processing.




          PP material actually has a lower density, so the product is thinner than other materials such as PVC and PET after blister molding, so we need to use thicker materials than other materials when designing PP products.
