Blister packaging is a general term that uses blister technology to produce plastic products and uses corresponding equipment to package the products. Products mainly include: bubble shells, trays, blister boxes, synonyms include: vacuum cover, blister, etc.
Blister packaging materials and their characteristics
1. PVC blister packaging
PVC sheet has high toughness and is not easy to burn. It will produce chlorine gas when burned, which will have a certain impact on the environment. PVC is easy to heat seal and can be sealed with a sealing machine and high-frequency edge sealing. It is the main raw material for the production of transparent blister products. PVC sheet is a widely used and popular material. PVC film can be divided into two types: environmentally friendly and non-environmental. It can be made into various blister packaging products such as transparent, colorful, anti-static, gold-plated, and flocked. The main features are high transparency, good surface gloss, few crystal points, small water marks, wide use, strong impact resistance, and easy to form. The products are widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery, etc. Product outer packaging.
2. PS blister packaging
PS hard sheets have low density, poor toughness, and are easy to burn. When burned, they produce styrene gas (a harmful gas), so they are generally used to produce various industrial blister trays. PS sheet is a new type of environmentally friendly packaging material that has been developed in recent years. With its excellent thermoforming performance, good environmental performance and hygienic performance, it is widely used in medicine, food, toys, and electronics.
3. PET blister packaging
PET hard sheet has good toughness and is a new material that has been developed in recent years. With its excellent toughness, high strength, high transparency, and recyclability, it is easy to burn and does not produce harmful gases when burned. It is an environmentally friendly material and is gradually being banned. However, the price is high. It is suitable for making high-end blister products. Blister blister shells in European and American countries generally require the use of PET material, but its thermal melting point is high, which brings great difficulties to high-frequency packaging.
4. PETG blister packaging
PETG material is to solve the problem of high thermal melting point of PET material. People compound a layer of PVC film on the surface of PET and name it PETG, but the price is higher. Mainly used in electronics, food, toys, color box windows, collar supports, footwear packaging, etc.
5. PP blister packaging
PP sheet uses polypropylene resin as the main raw material, adding various technical color masterbatch, toughening agent and brightening agent, and is made through mixing, plasticizing extrusion, three-roller calendering, cooling, traction and winding. . PP sheet has the characteristics of non-toxic, odorless, hygienic, high mechanical strength and good barrier properties, and can be used for packaging in industry, agriculture, fruit and other industries. The trays made of PP anti-slip sheets have a smooth and beautiful surface and are very popular among users. PP sheets are also suitable for packaging of highly cold-resistant frozen foods, such as ice cream boxes, dumpling boxes, glutinous rice balls boxes, etc.
