All kinds of plastic bottles can be filled with different liquids according to their materials, such as PET materials can not be filled with wine, oil and other substances. According to the number of the bottom of the plastic products, the liquid can be filled is different.

1. "1" at the bottom of the bottle belongs to pet (polyethylene terephthalate) which is commonly used in the production of mineral water bottles and carbonated beverage bottles, but its heat resistance is only up to 70 ℃, when it is filled with high-temperature liquid or heated, it is easy to deform, and there are substances harmful to human body dissolving out, which can not be put in the car in the sun, and can not be filled with alcohol, oil and other substances;

2. The bottom of the bottle is "2" HDPE (high density polyethylene), which is mostly used for cleaning products and bathing products. These containers are usually not easy to clean and easy to become a bacterial hotbed;

3. "3" at the bottom of the bottle belongs to PVC (polyvinyl chloride) which is generally not used to pack food. Harmful substances are easy to be produced at high temperature. If used, do not heat it;

4. The fresh-keeping film and plastic film are mostly made of "4" LDPE (low-density polyethylene), which is not strong in heat resistance, so they must be taken down when heating in microwave oven;

5. "5" PP at the bottom of the bottle belongs to (polypropylene) lunch box, which is the only plastic lunch box that can be put into the microwave oven, but before putting into the microwave oven, it is better to take off the cover first;

6. The bowl packed instant noodles box and fast food box made of "6" PS (polystyrene) can't be used to pack strong acid and strong alkaline substances, and try to avoid using fast food box to pack hot food.

Extended data:

Consumers should try to avoid the repeated use of aging and perishable plastic appliances. It is better not to reuse beverage bottles for many times, otherwise bacteria will easily grow and there are health risks. When using plastic containers, be sure to see clearly the numbers marked in the triangle at the bottom of the bottle. Only when you know the material properties can you use it in a suitable environment. In particular, we should be alert to the recycling of plastic waste in the market.

Purchased recycled materials and contaminated raw materials cannot be used to make plastic packaging containers, tools and other products for food. The bottles and containers made from recycled plastic waste are usually rough in workmanship, without trademarks or environmental protection recycling marks.
