Blister packaging is a commonly used packaging with a blister process to produce plastic products, and with the corresponding equipment for product encapsulation of the general term. 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 features.
pvc blister packaging generation process
1, the production of pvc blister packaging mold
production of pvc blister packaging, the first thing you need to do is to understand the need to make the packaging requirements and specifications, and then according to the specifications of the mold production, production of molds after the mold drying process, and pattern packaging needs on the mold Surface smoothness treatment. In general, pvc blister packaging molds are mainly made of plaster.
2, the pvc hard sheet softening
This step first of all to the pvc hard sheet processing. It is to cut it to a certain size according to the size of the mold. Then the cut pvc hard sheet is heated in a constant temperature furnace for softening treatment.
3, the softened pvc attached to the mold
First of all, the production of 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, and 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, show good results.
2, excellent surface decorative properties, can be printed without surface treatment, easy to press patterns, easy metal processing (vacuum plating metal layer)
3, has good mechanical strength.
4, good barrier properties to oxygen and water vapor.
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 packages 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.
