Blister Packaging PVC sheet

Blister packaging of the five timber

First, PVC sheet toughness is high, not easy to burn, burning will produce chlorine, the environment caused a certain impact, PVC easy heat, can be used sealing machine and high frequency edge, is the production of transparent plastic products, the main raw material. PVC sheet is a widely used and popular materials, PVC film can be divided into two kinds of environmentally friendly and environmentally friendly, can be made transparent, color, anti-static, gold-plated, flocking and other blister packaging products, its It is widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and so on. It is widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery, etc. Product packaging.

Second, PS hard chip low density, poor toughness, easy to burn, burning will produce styrene gas (a harmful gas), it is generally used to produce a variety of industrial plastic tray. PS sheet is now developed several years of new environmentally friendly plastic packaging materials, with its excellent thermoforming performance, good environmental performance and health performance, widely used in medicine, food, toys, electronics.

Third, PP sheet to polypropylene resin as the main raw material, add a variety of process masterbatch, toughener and brightener, after mixing, plastic extrusion, three roll calendering, cooling, traction and winding process production. PP sheet with non-toxic, tasteless, health, high mechanical strength and good barrier characteristics, can be used for industrial, agricultural, fruit and other industries packaging. PP anti-skid pieces made of the box made of smooth, beautiful, welcomed by the user. PP sheet is also suitable for high cold frozen food packaging, such as ice cream box, dumplings box, soup box and so on.

PP plastic with: environmental protection, beautiful, silk screen, Ke Yin, bronzing, high temperature, low temperature, high transparency, resistance to easy to fold, the product meets the food testing standards (also may not), can be microwave.

PP shortcomings: low dimensional accuracy, lack of rigidity, poor weather resistance, easy to produce "copper harm", it has a post-contraction phenomenon, stripping, easy aging, brittle, easy to deformation. Fourth, PET hard film toughness is good, is now developed several years of new materials. With its excellent toughness, high strength, high transparency, and recyclable use, easy to burn, do not produce harmful gases when burning, environmentally friendly materials and gradually banned PVC, but the price is high. Suitable for high-end plastic products, Europe and the United States blister blister generally require the use of PET materials, but its high melting point, high frequency package to bring great difficulties.

5, PETG material is to solve the problem of high melting point PET material, people in the PET surface composite layer of PVC film, named PETG, but the price is higher. Mainly used for electronics, food, toys, color box window, collar, footwear packaging. [span] its advantages are as follows:

1. Has excellent transparency and finish, show good results.

2. Excellent surface finish, can be printed without surface treatment, easy to suppress patterns, easy to metal treatment (vacuum plating metal layer)

3. Has a good mechanical strength.

4. Good barrier to oxygen and water vapor.

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

6. Non-toxic, hygienic and reliable, can be used for food, medicine and medical equipment packaging, and Y-ray [span] the packaging of their items disinfection.

7. Good adaptability to environmental protection, can be economically and easily recycled; incineration of its waste, does not produce harmful substances harmful to the environment. Such sheets are considered to be an ideal packaging material that meets the requirements of (ROSH) environmental protection.
