Paper Plastic Packaging Co., Ltd. is a manufacturer that provides various customized plastic packaging bags. It has sorted out some common sense about plastic packaging bags. While everyone is concerned about food safety, we must not ignore the safety of food plastic packaging containers. . Here, let us first popularize some common sense of plastic packaging: Common sense of plastic packaging bags: Material signs of plastic containers: Generally speaking, the signs of plastic containers are all at the bottom, with a triangle symbol with numbers 1 to 1 in the triangle. 7. Each number represents a type of plastic container. Due to their different materials, there are also different taboos on their use. Roughly: marked with numbers“1”, for common mineral water bottles, carbonated beverage bottles, etc., heat-resistant to 70 ℃ and easy to deform, there are substances harmful to the human body melted, after 10 months of use, may release carcinogens; marked with numbers“2”, used for containers of detergents, shampoos, shower gels, edible oils, pesticides, etc., can not be used as water cups, or as storage containers for other items, do not recycle; marked with numbers“3”, mostly used to make water pipes, raincoats, school bags, building materials, plastic films, plastic boxes and other utensils, good plasticity, cheap price, easy to produce bad substances at high temperature, rarely used for food packaging; marked with numbers“4”, mostly used in the manufacture of plastic bags that can be seen everywhere. Harmful substances are produced at high temperatures. After the toxic substances enter the human body with food, it may cause diseases such as breast cancer and birth defects of newborns; marked with numbers“5”, mostly used to make buckets, trash cans, baskets, baskets and food containers for microwave ovens, etc. The melting point can be as high as 167 ° C. It is the only plastic box that can be put in the microwave oven and can be reused after careful cleaning; marked with numbers“6”, Due to low water absorption, it is mostly used to make building materials, toys, stationery, rollers, and cup boxes or disposable tableware for fast food restaurants. Avoid using such fast food boxes to pack hot food, and do not use microwave ovens to cook instant noodles in bowls. ; marked with numbers“7”, commonly used in such materials as kettles, space cups, milk bottles, etc. Try not to use disposable tableware: Although some companies use the guise of environmentally friendly tableware, starch-based tableware or degradable tableware, the product quality has no small safety risks. The reality is that degradable tableware does not degrade, and environmentally friendly lunch boxes are not environmentally friendly. Seriously, this will bring serious risks to the health of consumers. When consumers use such disposable tableware, they unknowingly eat not only the food, but also the plastic, paraffin and stone powder in the fast food box. Moreover, the purchase and use of disposable tableware will directly turn these disposable things into garbage, which not only wastes resources, but also damages the environment.“green”consumption. It is not a problem to heat beverage bottles at low temperature: polyethylene terephthalate plastic (PET) is a material used for beverage bottles such as mineral water bottles and carbonated beverage bottles. It is heat resistant to 65°C and cold resistant to -20°C, suitable for warm drinks or room temperature beverages. According to the survey, the temperature of beverage heating cabinets in convenience stores is mostly controlled below 50℃. Therefore, when heating at a low temperature, there is no need to worry too much about the plasticizer oozing out of bottled hot drinks. Plastics are indeed easy to deform when heated. Some studies have reported that after 10 months of continuous use of beverage bottles, plasticizers may be released, so do not use them as water containers. There have also been reports on the Internet that when bottled water is exposed to the sun in the car, harmful substances such as plasticizers will be produced. However, in recent years, relevant domestic research has confirmed that the fully packaged bottled water is exposed to the sun in the car for 7 days without the precipitation of plasticizers, and the bacteria colonies. The total number did not change significantly. However, if it is bottled water that has been opened and drunk, due to the entry of external bacteria, it is easy to cause the growth of bacteria under high temperature conditions. Plastic cutlery whether or not“foam”There are great potential safety hazards: Disposable polystyrene foamed plastic tableware is prohibited to be used in my country. However, no matter whether the disposable polystyrene tableware is foamed or not, if the temperature exceeds 90 ℃ or is heated in a microwave oven, harmful substances will be precipitated. In addition, disposable plastic tableware will also contain carcinogenic fluorescent substances, which will bury unsafe hidden dangers for consumers' health. Toxic and harmful chemicals, the harm to the human body and the environment is insidious and chronic. Usually, you may feel fine. Over time, you will gradually accumulate and gradually accumulate. Once something happens, it will be too late to regret it. See the homepage of the website for the contact information of customized and wholesale various plastic packaging bags.
