pvc blister packaging generation process pvc blister packaging features

Blister packaging is a commonly used packaging with the blister process to produce plastic products, and with the corresponding equipment for product encapsulation of the general term. The blister packaging sheet after high temperature heating after vacuum suction, cooling molding for plastic box shape. Blister packaging raw materials are: PVC, PS, PP, PET, PETG and flocking, anti-static, conductive and other materials. Next I introduce pvc blister packaging generation process and pvc blister packaging characteristics.

pvc blister packaging generation process

1, the production of pvc blister packaging mold

production of pvc blister packaging, the first thing to do is to understand the need to make the packaging requirements and specifications, and then according to the specifications of the requirements of the mold production, production of molds after the mold drying process, and the pattern of the packaging needs to be on the surface of the mold smoothness. Processing. In general, pvc blister packaging mold is mainly made of plaster.

2, soften the pvc hard sheet

This step first of all, we need to deal with the pvc hard sheet. It is to cut it to a certain size according to the size of the mold. Then the cut pvc hard sheet is heated and softened in a constant temperature furnace.

3, the softened pvc attached to the mold

First of all, we should make ready molds and softened pvc placed in the vacuum chamber, and then the vacuum chamber suction, so that the softened pvc can be adsorbed on the mold. Then make it cool, finally can get the same pvc packaging products with the mold.

4, pvc blister packaging processing

This process is actually the initial production of good pvc blister packaging products trimming and finishing process, to be processed after it can be sold or used.

Pvc blister packaging features

1, with excellent transparency and finish, good display effect.

2, excellent surface decorative properties, can be printed without surface treatment, easy to press patterns, easy to metal treatment (vacuum plating metal layer)

3, has good mechanical strength.

4, oxygen and water vapor barrier performance is good.

5, good chemical resistance, can withstand a variety of chemical substances.

6, non-toxic, hygienic and reliable performance, can be used for food, drugs and medical equipment packaging, and can be Y-ray [span] on the items it packaged sterilization.

7, good adaptability to environmental protection, can be economically and conveniently recycled; incineration of its waste, does not produce environmentally harmful substances. This type of sheet is considered to be an ideal packaging material in line with (ROSH) environmental protection requirements.
