2, PS plate, low density, poor toughness, easy combustion, the combustion would produce styrene gas (harmful gases), and so are commonly used to produce all kinds of industrial blister tray. PS plate is a new kind of environmental protection packaging materials developed a few years now, with its good thermal formability, good environmental protection performance and health performance, widely used in medicine, food, toys, electronic.

3, PP sheet of polypropylene resin as the main raw material, add the various process color masterbatch, toughening agent and our agent, after mixing and plasticizing extruder, three-roll calender, cooling, traction and winding process. PP tablets are non-toxic, tasteless, hygienic, mechanical strength and obstructive properties, which can be used in the packaging of industries, agriculture, fruits and other industries. The surface of a box made of PP anti-skid plate is bright and beautiful, and is popular with users. It is also suitable for the packaging of cold and frozen foods such as ice cream box, dumpling box, soup box etc

PP disadvantages: low dimensional accuracy, insufficient rigidity, poor weather resistance, easy to produce "copper pollution", it has the shrinkage phenomenon, after demoulding, easy to aging, crisp, easy to deformation.

PP blister have: environmental protection, beautiful, can screen printing, KeYin, hot stamping, high temperature resistant, low temperature resistance, high transparency, resistance to bend easily fold, the products comply with the food testing standards (also don't need to) and microwave.

PET hard film is a new material that has developed in recent years. With its good toughness, high strength, high transparency, and can be recycling use, easy to burn, burns does not produce harmful gases, belongs to the environmental protection material and clamp down on PVC, but the price is high. It is suitable for high grade absorbency products, the European and European countries are generally required to adopt PET material, but its thermal melting point is high, which is very difficult to encapsulate the high cycle.

The PETG material is designed to solve the problem of the high melting point of PET materials, which is a layer of PVC, called PETG, which is called PETG, but is more expensive. Mainly used in electronic, food, toy, color box window, collar, shoe packing and so on.

The advantages are as follows:

Excellent transparency and smooth finish, showing good results.

The surface decoration is excellent, it can be printed without the surface treatment, it is easy to press the decorative pattern, easy metal processing (vacuum metallized layer).

Good mechanical strength.

Good for oxygen and water vapor barrier.

Chemical resistance is good, and can be corroded by various chemicals.

Non-toxic, reliable health, available in the packaging of food, medicine and medical equipment, and can be sterilized for the contents of the articles wrapped in the Y ray [span].

7, the adaptability of environmental protection is good, but the economy is easy to recycle. When incinerating its waste, it does not produce harmful environmental substances. The material is considered an ideal packaging material for the environmental protection requirement (ROSH).
