Printed Blister Tube Processing technology

A plastic processing technology, the main principle is to flatten the plastic sheet hardening soft, the use of vacuum adsorption on the mold surface, after cooling molding, widely used in plastic packaging, lighting, advertising, decoration and other industries.

Blister packaging: the use of plastic production process 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.

The main advantage of plastic packaging is to save raw and auxiliary materials, light weight, easy transportation, good sealing performance, in line with the requirements of environmentally friendly green packaging; can be packaged any shaped products, packing without additional cushioning material; transparent packaging products visible, Beautiful appearance, easy to sell, and suitable for mechanization, automated packaging, easy to modern management, saving manpower, improve efficiency.

Production equipment editing

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.

Three fold blister packaging editing

Three fold blister packaging is the bubble into three sides (front, bottom, after), and more to form a bottom edge, so that the product can stand on the plane. Which is characterized by the use of high-frequency edge-sealing process, but in a certain position on the blister to do the buckle to connect the blister, if necessary, can also be marked with staples, in the selection of PET hard film can be used to achieve environmentally friendly materials The purpose, suitable for large diameter product packaging.

Should pay attention to the problem: 1. Because there is no high-frequency machine edge, the edge of the need for high-quality cutting in the cut to complete; 2 buckle tightness to moderate.

Thermoforming process diagram

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

[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 blister packs 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.
