Blister is a kind of plastic processing technology. The main principle is to heat the flat plastic hard sheet to soften it, then use vacuum to absorb it on the mold surface, and cool it to form. It is widely used in plastic packaging, lighting, advertising, decoration and other industries.
The main advantages of blister packaging are that it saves raw and auxiliary materials, is light in weight, convenient to transport, and has good sealing performance, which meets the requirements of environmentally friendly green packaging; it can package any special-shaped products without additional cushioning materials for packing; the packaged products are transparent and visible, Beautiful appearance, easy to sell, and suitable for mechanized and automated packaging, convenient for modern management, saving manpower, and improving efficiency.
Blister packaging materials are the main raw materials for packaging production. After a whole piece of product is produced, a single small product will be left, and then there will be some product margins that are generally confused and often confused.
The materials commonly used in blister packaging factories are PP, PET, PVC, PET, etc. There are certain specifications for the thickness of the blister: 0.12mm—1.0mm is a normal thickness; 10mm or more is a thick sheet material, but the price is relatively high;
Types are: tray/inner tray, blister box, double-fold blister box, heaven and earth cover blister box, double blister, double-fold blister, tri-fold blister, half-fold blister, blister card, blister card , Folding box type blister, etc.
blister is mainly used for product packaging, and its advantages in packaging:
1. Blister packaging can improve the price and image of the product itself, and also has the role of shaping and dissemination, which has a significant impact on the company's brand image and popularity.
2. Blister packaging is also for the purpose of displaying and protecting products. The packaged products are mostly small commodities, which can be placed or hung on the shelves of supermarkets, so that the products can be perfectly displayed in front of customers to promote product sales.
3. Blister packaging is for the purpose of separation, shockproof and foil. It can pack many and small products to make the product more beautiful.
With the continuous development of various domestic production and packaging and logistics industries, it has established the future development trend of plastics.
