Blister packaging is the process of blistering a sheet of material through a vacuum forming process. Sheet is a widely used and popular material. Film can be divided into environmental protection and non-environmental protection. It can be made into transparent, colored, anti-static, gold-plated, flocked and other blister packaging products. High transparency, good surface gloss, less crystal point, small water grain, wide application, strong impact resistance, and easy to shape. The products are widely used in toys, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and other products. The following Shenzhen plastics manufacturers for everyone on the blister packaging process and characteristics.

1. Before producing blister packaging, the first thing to do is to understand the requirements and specifications of the required packaging, then make the mold according to the specifications, dry the mold after making it, and smooth the surface of the mold according to the needs of the packaging. Degree of processing. In general, the mold is mainly made of gypsum.

2. Softening the hard piece requires first processing the hard piece. Cut to a certain size according to the size of the mold. The cut piece is then subjected to a heat softening treatment in a constant temperature oven.

3. The prepared mold is softened and placed in a vacuum chamber, and then the vacuum chamber is inhaled so that the softened one can be adsorbed on the mold. It is then allowed to cool, and finally the same blister pack product as the mold can be obtained.

4. The process of blister cutting is the process of trimming and finishing the initially produced blister packaging products, which can be sold or used after being processed.

As one of the most widely used packaging materials, blister is not without reason. It has the following characteristics:

1. Non-toxic, reliable hygienic performance, can be packaged with medical equipment, and can be disinfected by Y-ray.

2. Has good mechanical strength.

3, the surface decoration performance is excellent, can be printed without surface treatment, easy to press the pattern, easy metal treatment (vacuum metal plating)

4, good chemical resistance, can withstand the erosion of a variety of chemicals.

5. Good barrier to oxygen and water vapor.

6, with transparency and smoothness, display effect is good.

7. It has good adaptability to environmental protection and can be recycled economically and conveniently; when it is burned, it does not produce harmful substances. Such sheets are considered to be packaging materials that meet the (ROSH) environmental protection requirements.
