1. PVC sheet has high toughness and is not easy to burn. It will produce chlorine when burned, which will affect the environment to a certain extent. 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 producing transparent plastic 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, easy to burn, and styrene gas (a harmful gas) will be produced 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 gases 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 the use of PET materials, but their thermal melting point is relatively high, which brings great difficulties to high-frequency packaging. In order to solve this problem, people use PET materials on the surface of PET. Layer PVC film, named PETG, but the price is higher. Mainly used in electronics, food, toys, color box windows, collar supports, shoe packaging, etc. Its 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 press patterns, easy to metal processing (vacuum metal coating) 3. With good mechanical strength. 4. Good barrier performance to oxygen and water vapor. 5. Good chemical resistance, 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 sterilized for 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 are produced. PET sheet is considered to be an ideal packaging material that meets (ROSH) environmental protection requirements. 4. PETG sheet, also called GPET sheet, is made of an amorphous PET resin modified with cyclohexanediol. The biggest advantage of PETG sheet is good heat sealing performance, easy operation during sealing, good sealing effect and easy glue bonding. At the same time, its chemical resistance, optical properties, and scratch resistance are also very good. PETG has passed the US FDA's food contact standards and can be used in the packaging of food and personal health products, medical and health equipment and food, as well as electronic device packaging. Its advantages are as follows: 1. Good transparency, suitable for products requiring high transparency. 2. Excellent impact strength and rigidity. 3. Excellent processability. It can be processed by sawing, die-cutting, drilling and laser cutting. It can also be cold and hot bending, bonding, welding and polishing, printing and painting; And cold bending does not whiten, the appearance is bright. 4. Good thermoformability, can be formed without preheating, high precision, good deep formability, no cracking and uniform thickness. 5. Low flammability, good fire resistance, non-combustion, low smoke emission, no harmful substances after burning. 5. PP sheet is made of PP resin through the process of brewing, calendering and trimming. It has light weight, bright and calm surface, good heat resistance, high mechanical strength, excellent chemical stability and insulation It has the characteristics of sex and non-toxicity, and can be made into daily necessities such as beverage cups and food boxes after thermoforming. 6. GAG is a three-layer composite sheet. It is a three-layer composite sheet produced by co-extrusion of the middle layer APET and the upper and lower layers of PETG raw materials in an appropriate ratio. It is especially suitable for packaging boxes that need to be bonded by high-frequency heat sealing and glue. Its advantages are as follows: 1. Good transparency, transparency can reach more than 90%, good texture, suitable for products that require high transparency. 2. Excellent impact resistance and rigidity, the material is hard and durable, suitable for applications with high impact resistance. 3. Excellent processability. It can be processed by sawing, die cutting, drilling and laser cutting. It can also be cold bending and hot bending, bonding, welding and polishing, printing and painting; cold bending is not whitening, and the appearance is bright. 4. Good thermoformability, can be molded without preheating, high precision, shrinkage rate is about 0.5%; deep formability, no cracking and uniform thickness. 5. Environmental protection, can be recycled and used without polluting the environment. 6. Excellent food hygiene. The material is PETG, which can meet all major food regulations, such as FDA or BGA. It is suitable for food container packaging and other purposes... 7. Good fire resistance, no combustion-supporting, low smoke emission, no after burning Harmful substances.
