Environmental protection plastic (structure: synthetic resin, plasticizer, non random agent, pigment) bag is one of the products of our company. The product quality is good, the price is reasonable, and it is trusted and praised by customers. Generally, aluminum foil bags should be kept away from direct sunlight and fire sources. They can be kept for 2 years at room temperature of 25 ℃. Aluminum foil bag is also known as polyamide 66 or nylon 66. Yellowish translucent or milky white opaque resin. The relative density is 1.14-1.15, and the melting point is 259-267 ℃. Wear resistance, oil resistance, self-lubricating, heat resistance, strength, rigidity is the highest aliphatic nylon varieties. The tensile strength is 75.9-82.9mpa, the compressive strength is 91mpa, the impact strength (notch) of cantilever beam is 4Kj / m, the thermal deformation temperature is 75 ℃, the hardness is R120, the volume resistivity is 1015 Ω· cm, the dielectric strength is 35kV / mm, and self extinguishing. It is prepared by polycondensation of adipic acid and hexanediamine. It can be processed by extrusion, injection molding and blow molding. It can be reinforced, filled and alloyed. A large number of materials are used for fiber and tire curtain. Let's introduce the types of materials for environmental plastic bag.

1. Pet (chemical formula: C6H6) ethylene glycol dicarboxylate) mineral water bottles, carbonated beverage bottles are made of this material. Hot water can not be used in beverage bottles. The material is heat-resistant to 70 ℃ and is only suitable for warm or frozen drinks. However, when filled with high-temperature liquid or heated (Ji ā R è), it is easy to deform and dissolve harmful substances. Moreover, scientists have found that this kind of plastic (structure: synthetic resin, plasticizer, stabilizer, colorant) product may release carcinogen after 10 months of use, which is toxic to human body. Therefore, drink bottles should be discarded when they are used up. They should not be used as water cups, or as storage containers, or other articles to avoid health problems.

2. HDPE (high density polyethylene) is a kind of plastic container (structure: synthetic resin, plasticizer, detergent and colorant) used for cleaning products and bathing products. The plastic bags currently used in supermarkets and shopping malls are mostly made of this material and can withstand 110 ℃ high temperature. The plastic bags used to mark food can be used for colorful clothes. Aluminum foil bag, also known as vacuum packaging, is based on the principle of atmospheric pressure. The main function of vacuum bag is to remove oxygen, so as to prevent food from spoilage. Vacuum packaging is a process in which the oxygen in the packaging bag and food cells is pumped out with an air extractor, which makes microorganisms lose their "living environment". Vacuum bag can also prevent food oxidation, make food taste unchanged, deterioration, reduce the loss of vitamin A and C. The outer shell of food packaging bag can separate food from oxygen, water vapor and stain. Anti leakage is also a necessary factor in packaging design. Some packages contain desiccants or deoxidizers to extend shelf life. Vacuum packaging or removing air from packaging bags is also a major food packaging method. Keeping food clean, fresh and safe within the shelf life is the primary function of the packaging bag. Generally, aluminum foil bags should be kept away from direct sunlight and fire sources. They can be kept for 2 years at room temperature of 25 ℃. Aluminum foil bag is also known as polyamide 66 or nylon 66. Yellowish translucent or milky white opaque resin. The relative density is 1.14-1.15, and the melting point is 259-267 ℃. Wear resistance, oil resistance, self-lubricating, heat resistance, strength, rigidity is the highest aliphatic nylon varieties. The tensile strength is 75.9-82.9mpa, the compressive strength is 91mpa, the impact strength (notch) of cantilever beam is 4Kj / m, the thermal deformation temperature is 75 ℃, the hardness is R120, the volume resistivity is 1015 Ω· cm, the dielectric strength is 35kV / mm, and self extinguishing. It is prepared by polycondensation of adipic acid and hexanediamine. It can be processed by extrusion, injection molding and blow molding. It can be reinforced, filled and alloyed. A large number of plastic containers used for fiber, tire curtain bearing cleaning products and bathing products can be reused after careful cleaning, but these containers are usually not easy to clean, and the original cleaning products are turned into special structures: hotbeds of capsule, flagellum and fimbriae. If the cleaning is not thorough, it is better not to use them again. 3. Polyvinyl chloride (PVC) according to the introduction, this material of plastic products (plastic products) easy to produce toxic (poison) harmful substances from two aspects, one is the production process (gu'ch é ng) is not fully polymerized single molecular vinyl chloride, the other is the harmful substances in plasticizer. These two substances are easy to separate out when encountering high-temperature CIS fat, and toxic substances enter the human body with food, which is easy to cause cancer. At present, the container of this material has been less used for packaging food. If in use, do not let it be heated. 4. LDPE (low density polyethylene) film, plastic film, etc. are all made of this material. The heat resistance is not strong. Generally, qualified PE film will melt when the temperature exceeds 110 ℃, leaving some plastic preparation that the human body can not decompose. Moreover, wrap food with plastic film and heat it (Ji ā R è), the oil in the food can easily dissolve the harmful substances in the film. Therefore, when food is put into the microwave oven (w ē I B ō L ú), the wrapping plastic film should be removed first. 5. PP (polypropylene) microwave oven lunch box made of this material, resistant to 130 ℃ high temperature, poor transparency, this is the only plastic box that can be put into the microwave oven and can be reused after careful cleaning. Special attention should be paid to the fact that some microwave oven lunch boxes are made of PP No.05, but the box cover is made of No.06 PS (polyphenylene (chemical formula: C6H6) ethylene). PS has good transparency, but it is not resistant to high temperature, so it can not be put into the microwave oven together with the box body. To be on the safe side, remove the lid before putting the container in the microwave oven. 6. PS (polystyrene) this is used to make bowl of bubble noodles box, foam fast food box material. It is heat-resistant and cold resistant, but can not be put into the microwave oven, so as to avoid releasing chemicals due to excessive temperature. And can not be used for strong acid (such as orange juice), strong alkaline substances, because of the decomposition of polystyrene is not good for the human body. Therefore, you should try to avoid using fast food boxes to pack hot food.
