After 6 years of R&D and production experience in the blister packaging industry, Shanghai Zhanshi Machinery Equipment Co., Ltd. describes the characteristics, types and functional uses of the blister machine as follows:

Definition of plastic machine:
 The blister machine (also known as the thermoforming machine) is a machine that sucks thermoplastic plasticized PVC, PE, PP, PET, HIPS and other thermoplastic plastic coils into high-grade packaging boxes and frames of various shapes. The vacuum softened vacuum is used to blister the softened plastic into various shapes of vacuum covers, blister trays, bulbs, and the like. Special recommendation: The blister machine produced by Zhanshi Machinery Co., Ltd. has the advantages of stable heating, strong vacuum, stable molding and good cooling effect.


The principle of plastic forming machine:
Plastic molding is also called thermoforming. This molding process mainly uses the vacuum suction generated by the vacuum pump to soften the heat.
The sheet plastic machine, the thermoplastic plastic sheet of PVC, PET, PETG, APTT, PP, PE, PS, etc. after the sheet blister machine is molded into various shapes of vacuum hoods by die, or attached to various shapes of products. s surface. Blister is divided into sheet blister and slab blister according to the thickness of the sheet.
The main structure of the machine is composed of feeding, pulling, upper and lower electric heating furnace, lower brake, multi-function adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, laying and vacuum device. And the common products of thick film blister are: household appliance liner, luggage, display rack accessories, decoration, car interior, bumper, fender, beauty equipment, light box shell, toy car shell, industrial panel, advertising light box , plastic LOGO, bathroom products, refrigerator liners and so on.

Blister forming Main features

▪ Thermoforming commonly used plastics and properties

▪ Thermoforming commonly used plastics

▪ Basic methods of thermoforming


Zhanshi Machinery is divided into the following categories for blister machines:

The types of plastic machine are divided into blister packaging series, sheet blister machine series, thick plate blister machine series, color aligning blister machine series, cutting machine series, blister matching equipment, mold series
Can be divided into: a single male molding, single negative molding, three-die molding, composite molding, clamping equipment, heating equipment, vacuum equipment, compressed air equipment, cooling equipment, demoulding equipment, control equipment


Which industries are the main applications of blister machines:
Plastic packaging industry (blister packaging, plastics, batteries, toys, gifts, hardware, home appliances, electronics, stationery, decoration)
Food packaging industry (fast food box, fruit tray, biscuit box)
Pharmaceutical industry (pill packaging, tablet packaging)
Industrial cooling tower cooling water deflector, etc.
Decorative three-dimensional relief pattern, plastic ceiling, siding, automotive materials, sanitary equipment and other manufacturing industries.
Suitable for the production of various color sheets: polyethylene PS, polyvinyl chloride PVC, plexiglass, ABS, polymethyl methacrylate; flocking sheet; environmentally friendly sheet APET, PET, PP, etc.; photodegradable materials; biodegradation Plastic products such as materials.

The main features of the blister:
(1) Adaptability of product specifications Strongly, the plastic molding method can be used to manufacture extra large, extra small, extra thick and extremely thin products. The sheet can be as thin as 1~2MM, even thinner, and the product area can be as large as 10m2. As small as a few square millimeters, the wall thickness can be as large as 20mm and as small as 0.1mm.
(2) Application range of products, daily blister packaging, small plastic blister packaging, automotive blister packaging, electronic product blister packaging, food blister packaging, cosmetic blister packaging, computer peripheral equipment blister packaging, toy blister packaging, sports Blister packaging, stationery, blister packaging, etc.
(3) less equipment investment
(4) Easy mold manufacturing, (with plaster mold, copper mold, aluminum mold ~~~~)
(5) High production efficiency.


Plastics can be divided into thermoplastics and thermosets according to their heating behavior. The materials used for thermoforming are mostly thermoplastic materials.
The single or multi-layer composite plastic sheet (board) used for thermoforming must have the following process properties.
1: plastic memory
2: hot stretching
3: thermal strength
4: molding temperature
Thermoforming common plastic


A PVC (characterized by less impurity content, better transparency, lower price, good dielectric properties, flame retardancy and self-extinguishing)
Two PP (rich source, cheap price, excellent performance, wide range of uses.
1, low density (PP colorless, odorless, tasteless, non-toxic, flammable, white appearance, density is 0.90~0.91g/cm3.)
2, good mechanical properties PP rigidity, excellent elongation, good resistance to stress cracking
3, better heat resistance
4, good chemical stability
5, transparency, water and water resistance
6, processing and use is strong
Three PE (one of the most widely used and widely used plastic varieties, odorless, tasteless, non-toxic, flammable)
Four PS (plastic is hard, brittle, transparent, no smell, black smoke when burning, easy to dye and process, low hygroscopicity, dimensional stability, electrical insulation and thermal insulation.)
1, high transparency and gloss
2, coloring, excellent hygiene
3, excellent dielectric properties
4, excellent molding performance


The basic method of thermoforming of plastic machine
There are many methods for plastic thermoforming, which can be divided into two types according to molding power: compression molding and differential pressure molding. According to the forming mold, it can be divided into a single positive mold, a single negative mold, a counter mold, a moldless method, and the like.
Molding, also known as mechanical stretch forming, is a molding method in which a plastic sheet is molded into various parts by means of mechanical pressure or self-weight in the form of a single mold or a counter mold. The male mold means that the shape of the mold is convex, and the female mold means that the shape of the mold is concave, the mold only forms one side of the product, and the other side is exposed to the air, which is different from the press forming of one molding process. This method is basically suitable for all thermoplastics.
