In the retail and fresh produce areas of large supermarkets, there will be several rolls and rolls in bags. From fruits and vegetables to chicken, fish, eggs, and meat, you need to use them. The rolls are set up for customers to pick up and use by themselves.
What is the difference between the continuous roll bags in the supermarket and other common food plastic bags? Can purchased food be stored in the refrigerator or microwaved with a plastic bag?
Common plastic products can be divided into polyethylene terephthalate (PET/01), high density polyethylene (HDPE/02), polyvinyl chloride (PVC/03), low density polyethylene (LDPE/04) , polypropylene (PP/05), polystyrene (PS/06), and other plastics (PC/07), all of which will have a triangular recyclable sign.
The inside of the triangle is marked with serial numbers 01 to 07, of which No. 1 PET, No. 2 HDPE, No. 4 LDPE, No. 5 PP, and No. 6 PS can be used to contain or contact food.
Food plastic bags are generally made of No. 2 HDPE material, while food plastic wrap is generally made of No. 4 LDPE material. These two materials are the most common plastics in supermarket food areas.
In the process of heating food with plastic bags, not only will the plasticizer phthalates in the plastic bags be released at an accelerated rate, but they will also dissolve into various oils in the food, allowing you to "absorb" plasticization more effectively. agent! So don't heat food in plastic bags.
Now it is popular to use environmentally friendly bags, which can be effectively degraded, no pollution to the environment after throwing, and no pollution to food during the packaging process. The commonly used environmentally friendly roll-up bags in the market, shopping bags are made of sugarcane, corn and other plants, and stone paper roll-up bags are all good environmental protection bags.
It is not recommended to use the roll bag repeatedly to store food except for food. After use, it can be used to store garbage. The clean bag can also be used to store some other shoes and tools.
