Blister packaging is a general term for a plastic product produced by a plastic packaging process and packaged with corresponding equipment. After the blister packaging sheet is heated at a high temperature, the sheet is vacuum-aspirated and cooled to form a plastic box. Blister packaging of raw materials are: PVC, PS, PP, PET, PETG and flocking, anti-static, conductive and other materials. Next Xiaobian introduced pvc plastic packaging production process and pvc plastic packaging features.
Pvc plastic packaging production process
1, making pvc plastic packaging mold
Before making pvc blister packaging, the first thing to do is to understand the requirements and specifications of the packaging that needs to be produced, then make the mold according to the specifications, make a good mold and then dry it, and the pattern needs to be smooth on the surface of the mold. Degree of processing. Under normal circumstances, pvc plastic packaging mold is mainly made of gypsum.
2, the pvc hard sheet softened
This step must first deal with pvc hardware. According to the size of the mold, it will be cut into a certain size. Then, the pvc plate prepared was heat-softened in a constant temperature oven.
3, the softened pvc attached to the mold
First, the prepared mold and the softened pvc are placed in a vacuum chamber, and then the vacuum chamber is inhaled so that the softened pvc can be adsorbed on the mold. It is then allowed to cool and finally the same pvc packaging product as the mould can be obtained.
4, pvc plastic packaging processing
This process is in fact the process of edging and finishing the initial production of pvc blister packaging products, and can be sold or used after it is processed.
Pvc plastic packaging features
1, has excellent transparency and finish, showing good results.
2, excellent surface decoration performance, can be printed without surface treatment, easy to suppress the pattern, easy metal processing (vacuum plating metal layer)
3, has a good mechanical strength.
4. Good barrier properties against oxygen and water vapor.
5, good chemical resistance, can withstand the erosion of a variety of chemical substances.
6, non-toxic, reliable health performance, can be used to food, medicine and medical equipment packaging, and can sterilize its packaged items by Y-ray [span].
7. The adaptability to environmental protection is good, and it can be recycled economically and conveniently; when it is burned, no harmful substances harmful to the environment are produced. This type of sheet is considered to be an ideal packaging material that meets (ROSH) environmental protection requirements.
Editor's summary: On the pvc plastic packaging production process and pvc plastic packaging features introduced here, and hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
