Five Characteristics of Materials Used in Blister Packaging

- May 08, 2018-

Blister packaging is the general term for plastic products produced by the plastic blister process and packaged with corresponding equipment. Products include: blister, tray, plastic boxes, synonym: vacuum cover, blisters and so on.


Five Blister Packaging Materials and Features


1. PVC sheet has high toughness, is not easy to burn, will produce chlorine when it is burned, and has certain impact on the environment. PVC is easy to heat and can be sealed by sealing machine and high frequency, which is the main raw material for producing transparent plastic products. PVC sheet is a widely used and popular material, PVC film can be divided into two kinds of environmental protection and environmental protection, can be made of transparent, colored, anti-static, gold-plated, flocking and other various plastic packaging products, Features Mainly high transparency, good surface gloss, less crystal point, small water mark, wide use, strong impact resistance, and easy molding, the products are widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery, etc. Product packaging.


2.PS hard film has low density, poor toughness, easy to burn, and generates styrene gas (which is harmful gas) when it is burned, so it is generally used to produce various industrial plastic trays. PS sheet is a new type of environmental protection packaging material developed in recent years. With its excellent thermoforming performance, good environmental performance and sanitary performance, it is widely used in medicine, food, toys and electronics.


3. PET toughness is good, is a new type of material developed in recent years. With its excellent toughness, high strength, high transparency, and recyclable recycling, it is easy to burn, does not produce harmful gases when it is burned, and it belongs to environmental protection materials and gradually bans PVC, but its price is high. It is suitable for high-grade plastic products. The blister blister of European and American countries generally requires the use of PET material, but its high thermal melting point makes it difficult for high-frequency packaging.


4. PETG material is to solve the problem of high thermal melting point of PET material. People laminate a layer of PVC film on the PET surface, named PETG, but the price is higher. Mainly used for electronics, food, toys, box window, collar care, footwear packaging.


5.Polypropylene resin as the main raw material for PP sheet, adding various masterbatch, toughening agent and brightening agent in various processes, such as mixing, plastic extrusion, three-roll calendering, cooling, traction and winding production. PP sheet has the characteristics of non-toxic, odorless, sanitary, high mechanical strength and good barrier properties, and can be used for packaging in industries such as industry, agriculture and fruits. The surface of the tray box made of PP anti-slip sheet is smooth and beautiful, and it is welcomed by users. PP sheet is also suitable for packaging of high cold-resistant frozen foods, such as ice cream boxes, dumpling boxes, dumpling boxes, etc.
