Blister is a plastic processing technology, the main principle is to flat plastic sheeting softened heat, the vacuum adsorption on the mold surface, after cooling forming, widely used in plastic packaging, lighting, advertising, decoration and other industries.


Blister packaging with the film called the hard film or film, commonly used PET (polyethylene terephthalate) film, PVC (polyvinyl chloride) film, PS (polystyrene) film.

 

PS rigid film low density, poor toughness, easy to burn, combustion will produce styrene gas (which is a harmful gas), it is generally used to produce a variety of industrial plastic tray.

 

PVC hard film moderate toughness, easy to burn, combustion will produce chlorine, causing some impact on the environment, PVC easy to heat, sealing machine and high frequency machine can be used to seal the edge, is the main raw material for the production of transparent plastic products.


PET hard film toughness, high transparency, easy combustion, combustion does not produce harmful gases, are environmentally friendly materials, but the high price, suitable for high-grade plastic products, plastic blisters in Europe and the United States generally require the use of PET hard film, but It is not easy to heat, to bring great difficulties to the package, in order to solve this problem, people in the PET surface composite layer of PVC film, named PETG hard film, but the price is higher.

Blister process a wide range of applications, mainly in the packaging, shade production, acrylic light boxes, industrial plastic shell and plastic parts production. The company's current business scope only relates to the packaging industry and the thickness of less than 1.5mm, an area of less than 660X1100mm the area of plastic products. Packaging products from the function is divided into two categories: one is to display, protect, beautify the product for the purpose of the transparent series, packaging products are mostly small commodities, placed or hanging in the supermarket shelves, the choice of materials are mostly transparent Better PET and PVC products include: mask, card blister shell, card blister shell, double blister heat seal, double blister pack and transparent folding box; the other is to protect, separate, shockproof, foil The purpose of the tray, plastic box series, packaging products are mostly electronic, IT, industrial parts and cosmetics, the choice of materials mostly PS (color, antistatic and flocking, etc.), products include: tray, the care, plastic Boxes, flocking Blister, anti-static plastic, conductive plastic tray, turnover tray.
