Although the regular production of plastic food packaging is safe, it is also necessary to pay attention to the method in use, otherwise it will bring negative effects.

Do not use high-temperature food in plastic bags for a long time: In daily life, people often see hot fried foods in plastic bags, such as fried cakes, fried dough sticks, etc. Some people put plastic bags on tableware for customers. use. Plastic bags contain hot foods that are directly imported. After the temperature exceeds 50 °C, the plastic bags will release toxic gases. For long-term use of such plastic bags, light can cause dizziness, nausea, vomiting, diarrhea and other discomforts. It can lead to lead poisoning and increase the probability of cancer.

Do not use a general plastic bag to heat in a microwave oven: use a microwave to heat food. It is best to use a plastic bag and a special container for the microwave oven.

Do not store food in a general plastic bag in the refrigerator: use the plastic wrap for refrigerated and frozen food in the refrigerator instead of ordinary plastic bags. Due to the special process and raw materials of cling film, it has good ventilation and fresh-keeping properties. However, when the ordinary plastic bag is used for a long time, the food will quickly deteriorate and rot, which will not achieve the purpose of preservation.

The thermoplastic resin has the advantages of simple processing and high mechanical energy. The disadvantage is poor heat resistance and rigidity.

After the resin is heated, it undergoes a chemical change, gradually hardens and forms, and then does not soften under heat, nor dissolves. The thermosetting resin has a molecular structure which is a bulk type, and includes most of the condensation resin. The thermosetting resin has the advantages of high heat resistance and deformation under pressure. The disadvantage is that the mechanical properties are poor. Thermosetting resins include phenolic, epoxy, amino, unsaturated polyester, and silicone ether resins.

Fillers can improve and enhance the performance of plastics. For example, adding fiber can improve the mechanical strength of plastics; adding asbestos can enhance the heat resistance of plastics; adding mica can enhance the electrical insulation properties of plastics; adding graphite and molybdenum disulfide can improve the abrasion resistance and wear resistance of plastics. Adding fillers can also reduce the cost of plastics.
