Blister packaging is a general term used to produce plastic products using a blister process and use corresponding equipment to package the products. Products mainly include: blister, tray, blister box, synonyms are: vacuum cover, blister, etc. Understand the characteristics and advantages of blister packaging as follows:  

1. PVC sheet has high toughness and is not easy to burn. It will produce chlorine when it burns, which will affect the environment. PVC is easy to heat 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 environmental protection and non-environmental protection. It can be made into various blister packaging products such as transparent, colorful, anti-static, gold-plated, flocking, etc. The main features are high transparency, good surface gloss, few crystal points, small water lines, 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, and easy to burn. It will produce styrene gas (a harmful gas) when burned, so it is generally used to produce various industrial blister trays. PS sheet is a new type of environmentally friendly 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 hard film has good toughness and is a new type of material developed in recent years. With its excellent toughness, high strength, high transparency, and recyclability, it is easy to burn and does not produce harmful gas when burned. It is an environmentally friendly material and gradually banned PVC, but the price is high. It is suitable for high-end blister products. The blister shells in European and American countries generally require PET materials, but their thermal melting point is relatively high, which brings great difficulties to high-frequency packaging.

Fourth, PETG material is to solve the problem of higher thermal melting point of PET material. People compound a layer of PVC film on the surface of PET, named PETG, but the price is higher. Mainly used in electronics, food, toys, color box windows, collar supports, shoe packaging, etc.

The advantages are as follows:

1. It has excellent transparency and smoothness and good display effect.

2. Excellent surface decoration performance, can be printed without surface treatment, easy to suppress patterns, easy to metal treatment (vacuum metal coating)

3. It has good mechanical strength.

4. Good barrier performance to oxygen and water vapor.

5. Good chemical resistance and can withstand the erosion of a variety of chemical substances.

6. It is non-toxic and has reliable hygienic performance. It can be used for packaging food, medicine and medical equipment, and can be Y-ray [span] to sterilize the packaged items.

7. It has good adaptability to environmental protection and can be recycled economically and conveniently; when its waste is incinerated, no harmful substances harmful to the environment will be produced. Such sheets are considered to be an ideal packaging material that meets the (ROSH) environmental protection requirements.
