One、 PVC sheet has high toughness and is not easy to burn. When burning, it will produce chlorine gas, which will have a certain impact on the environment. PVC is easy to heat close. Sealing machine and high cycle edge sealing can be used. It is the main raw material for the production of transparent Blister products. PVC sheet is a kind of widely used and popular material. PVC sheet can be divided into environmental protection and non environmental protection. It can be made into transparent, color, anti-static, gold-plated, flocking and other plastic packaging products. Its main characteristics are high transparency, good surface luster, few crystal dots, small water lines, wide use, strong impact resistance, and easy to form. The products are widely used in toys and food , electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and other products.

Two、 PS hard disk has low density, poor toughness and is easy to burn. When it is burned, styrene gas (harmful gas) will be produced, so it is generally used to produce various industrial plastic pallet. PS sheet is a new type of environmental protection packaging material developed in recent years. It is widely used in medicine, food, toys and electronics because of its excellent thermoforming performance, good environmental protection performance and health performance.

Three、 Pet is a new material developed in recent years because of its good toughness. With its excellent toughness, high strength, high transparency, recyclability and recycling, it is easy to burn, and does not produce harmful gases when burning. It belongs to environmental protection materials and gradually banned PVC, but the price is high. It is suitable for high-grade Blister products. The blister shell in European and American countries generally requires PET material, but its high thermal melting point brings great difficulties to high cycle packaging. In order to solve this problem, 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 window, collar bracket, footwear packaging, etc. Its advantages are as follows:

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

2. Excellent surface decoration performance, printing without surface treatment, easy to press pattern, easy to metal treatment (vacuum plating metal layer)

3. Good mechanical strength.

4. Good barrier performance for oxygen and water vapor.

5. It has good chemical resistance and can withstand the erosion of various chemicals.

6. It is non-toxic and has reliable hygienic performance. It can be used for packaging of food, medicine and medical equipment, and can be sterilized by y-ray.

7. It has good adaptability to environmental protection and can be recycled economically and conveniently; when burning its wastes, it will not produce harmful substances to the environment. PET sheet is considered to be an ideal packaging material in line with the requirements of environmental protection (Rosh).

Four、 PETG sheet, also known as gpet sheet, is an amorphous PET resin modified by cyclohexanediol. The biggest advantage of PETG sheet is good heat sealing performance, easy to operate when sealing, good sealing effect and easy to glue. At the same time, its chemical resistance, optical performance, scratch resistance are also very good. PETG can be used in food and personal health products packaging, medical and health equipment food and other fields, as well as electronic device packaging through FDA food contact standards. Its advantages are as follows:

1. Good transparency, suitable for products requiring high transparency.

2. Excellent impact strength and rigidity

3. It has excellent processability. It can be processed by sawing, die cutting, drilling and laser cutting. It can also be cold bending and hot bending, adhesion, welding and polishing, printing and coating. The cold bending is not white, and the appearance is bright.

4. Good thermoformability, no preheating, high precision, good deep formability, no fracture and uniform thickness.

5. Low flammability, good fire resistance, no combustion support, low smoke emission, no harmful substances after combustion.

Five、 PP sheet is made of PP resin by beer out, calendering, edge cutting and other technological processes. It has the characteristics of light weight, bright and calm surface, good heat resistance, high mechanical strength, excellent chemical stability and insulation, non-toxic, etc. it can be made into daily necessities such as beverage cup and food box after hot forming.

Six、 Gag is a three-layer composite sheet. It is a three-layer composite sheet produced by CO extrusion of APET in the middle layer and PETG in the upper and lower layers according to the appropriate proportion. It is especially suitable for the packing box that needs high-frequency heat sealing and glue bonding. Its advantages are as follows:

1. Good transparency, transparency up to 90%, good texture, suitable for products requiring high transparency.

2. Excellent impact strength and rigidity, hard and durable material, suitable for high impact strength.

3. It has excellent processability. It can be processed by sawing, die cutting, drilling and laser cutting. It can also be cold bending and hot bending, adhesion, welding and polishing, printing and coating. The cold bending is not white, and the appearance is bright.

4. It has good hot formability and can be formed without preheating, with high precision and shrinkage of about 0.5%; it has good deep formability, no fracture and uniform thickness.

5. Environmental protection, recyclable and non polluting.

6. The product is made of PETG. It can meet all the main food regulations, such as FDA or BGA. It is suitable for food container packaging and other purposes

7. Good fire resistance, non combustion supporting, low smoke emission, no harmful substances after combustion.
