Seven common food packaging materials.biodegradable clear mailing bags Processing

　　No. 1 Plastic (PETE): Frequent mineral water bottle, carbonated beverage bottle, etc. The transparent plastic bottle made of it is often called "Baotter bottle". This plastic will deform because it is heat -resistant to 70 ° C, which is only suitable for installing warm or cold drinks. If high temperature liquid or heating, it is easy to deform, and releases harmful substances to the human body. Studies have also found that after 10 months of continued use, this kind of plastic will also release carcinogens, which is greatly harmful to the human body. The beverage bottle is thrown into the "recyclable" garbage after using it. Do not use it for a water cup. Avoid heating and cracking; try not to make other items in storage containers to cause health problems.

　　No. 2 plastic (HDPE) often makes cleaning products, bath products, etc. The packaging of common white medicine bottle, skin care, and bath products is made of this plastic. If you want to reuse, you need to use it after thoroughly cleaning. Breakthrough is that these containers are usually not easy to clean, and they will remain the original cleaning supplies, which are easy to turn into a hotbed of bacteria, so be careful. It is better to use well, and it needs to be classified and recycled.

　　No. 3 plastic (PVC) is often made: raincoats, building materials, etc.; good plasticity, cheap price; food cannot be packaged. This material is prone to harmful substances when it is high temperature, and even toxic substances are released in the process of manufacturing. Don't let it be heated during use.

　　No. 4 plastic (LDPE) is often made of plastic wrap. People are used to putting foods covered with plastic wrap in microwave oven to heat, thinking that the water in this food is not easy to lose and the taste of food is better. However, in fact, the phenomenon of a qualified PE plastic wrap will also appear hot -melt when the temperature exceeds 110 ° C. In addition, wrapped food with plastic wrap to heat, and the oil in food can easily dissolve the harmful substances in the plastic wrap. Therefore, before putting the food in the microwave oven, it is better to remove the cling film wrapped first. Good don't enter the microwave oven to heat.

　　Plastic (PP) is often made: microwave oven special meal box. This is the only plastic box that can be placed in a microwave oven, which can be reused after thorough cleaning. It is important to note that some microwave lunch boxes are indeed made of No. 5 PP, but the lid is made of plastic of other levels. Because the lid is often not able to resist the high temperature, it cannot be placed with the box body together with the box body. Enter the microwave oven. For the sake of insurance, the container is put in front of the microwave, and the lid is removed.

　　No. 6 Plastic (PS) is often made: bowl of instant noodles, fast -food boxes. When it comes to high temperature, it will release chemicals that are harmful to the human body; at the same time, it cannot be used for serving acid (if juice) and alkaline substances, because it will decompose carcinogens. Therefore, you should try to avoid packing hot foods for fast food boxes, and do not boil bowl instant noodles with a microwave oven. For the consideration of yourself and the environment, you still need to take a cautious attitude towards this disposable item.

　　No. 7 Plastic (PC), PC is a material used in large quantities, especially for making bottle, space cups, etc., which is controversial because it contains bisphenol A. Experts point out that in theory, as long as the bisphenol A is 100 % transformed into a plastic structure in the process of making PC, it means that the product has no bisphenol A at all, let alone the release. However, if there is a small amount of bisphenol A that is not converted into a PC plastic structure, it may be released and enter the food or drink. Therefore, pay special attention when using this plastic container. The residual bisphenol A in PC, the higher the temperature, the more release, the faster the speed. Those who are fully qualified can be used safely but cannot avoid defective products, and should not be used with PC water bottles.
