Blister Packaging Material requirements

Blister forming process

Thermoforming process diagram

General process: plastic sheet - cutting - sheet fixing - heating - forming - stripping - to the edge - finished

The use of plastic technology to produce plastic products, and the corresponding equipment to the product of the general name of the package. Blister packaging products include: blister, tray, plastic box, synonyms are: vacuum hood, blister and so on. Blister packaging equipment include: plastic molding machine, punch, sealing machine, high frequency machine, folding machine. Packaging the formation of packaging products can be divided into: card, suction card, double bubble shell, half bubble, folding bubble shell, three fold blister and so on.

Plastic molding of the material requirements]:

1. Blister molding can only produce relatively uniform wall thickness of the product, (generally chamfered slightly thin), can not be made of wall thickness difference between the plastic products

2. The wall thickness of the blister is generally in the range of 1 to 2 mm or more (the most commonly used thickness of the sheet for a small package is 0.15 to 0.25 mm)

3. The degree of stretch of the plastic molded article is limited, and the diameter of the plastic container is not more than 1 in diameter, and in the extreme case it is not more than 1.5

4. Blister forming the dimensional accuracy is poor, the relative error is generally more than one percent.

Classification of use of blistering

Blister packaging: the use of plastic technology to produce plastic products, and the corresponding equipment to the product of the general name of the package.

Blister packaging products include: blister, tray, plastic box, synonyms: vacuum cover, blister and so on.

Blister packaging is the use of plastic technology to produce plastic products, and the corresponding equipment for the general name of the package of goods.

Plastic products, mainly to the excellent flocking, PVC, PET, PP, PS, GAG and other plastic materials, high-grade production and a variety of plastic packaging for electronic, stationery, toys, hardware, food, Gift technology and other packaging products.

First, PVC sheet resistance is higher, not easy to burn, incineration will occur when the chlorine, the formation of the environment must be affected. PVC easy to heat, can be used sealing machine and high frequency edge, is produced transparent plastic finished the primary raw material.

PVC sheet is a widely used and highly anticipated information, PVC film can be divided into environmentally friendly and environmentally friendly two, can be made transparent, colorful, anti-static, gold-plated, flocking and other plastic packaging products. Its characteristics are mainly high brightness, good appearance, crystal point less, small watermark, wide use, impact resistance, and easy to shape, the goods are widely used in toys, food, electronic goods, medicine, electrical appliances, gifts, cosmetics , Stationery and other goods outside the packaging.

Second, PS hard chip density is low, poor tolerance, easy to burn, incineration will occur when the styrene gas (a harmful gas), it is generally used to produce a variety of industrial plastic tray. PS sheet is developed in recent years, the new environmentally friendly packaging materials, with its excellent thermoforming function, outstanding environmental protection features and cleaning functions, widely used in medicine, food, toys, electronics.
