Which is the best plastic container?
What are the plastic containers that can be used for water cups or beverage packaging?
Where can I buy these plastic containers?
01 Plastic canister: PET material with low heat resistance temperature. Mineral water bottles generally use this material and cannot be reused. Therefore, the national standard stipulates that PET materials cannot be used for bottled water;
02 Plastic container: high and low pressure polyethylene, which is safer, but the heat-resistant temperature is low, and hot water cannot be filled;
03 Plastic can: Polyvinyl chloride, which contains 100% plasticizer, that is, plasticizer. It is strongly not recommended to use. Remember that many cups were made of this material when they were young, and they smelled bad when filled with hot water;
04 Plastic container: high and low pressure polyethylene, which is relatively safe, but has low heat resistance temperature and cannot be filled with hot water;
05 Plastic canister: PP, which is polypropylene, recommended. Many lunch boxes and baby bottles use this material, with a temperature resistance of about 120°C;
06 Plastic jar: PS, polystyrene, a very brittle material, easy to crack, poor solvent resistance, and easy to decompose benzene at high temperature, not recommended;
07 Plastic can: generally refers to PC material, that is, polycarbonate. At present, it is easy to precipitate bisphenol A in international and domestic publicity, but this material has excellent transparency, excellent toughness, and excellent high and low temperature resistance. I personally think that baby bottles are not suitable However, the use of adult water cups and other products is not restricted in the national standard.
I think the best plastic container should be the No. 05 plastic container. The plastic canister marked 05 indicates that it can withstand high temperatures above 100 degrees. Generally, pp materials can withstand high temperatures up to 167 degrees. Therefore, you must pay attention to whether the bottom of the cup is marked with 5.
No. 1 plastic can (PET): mineral water bottles, soda bottles, etc. Above 70 degrees, it is easy to deform, so it cannot be used to hold hot water, nor can it be placed in the car in the sun.
No. 5 plain can (PP): common soy milk bottles, yogurt bottles, juice drink bottles, microwave oven lunch boxes, etc. Because the PP material can withstand high temperatures of up to 167°C, the plastic container made of No. 5 can be used in a microwave oven, and after cleaning, it can be reused. Therefore, the plastic bottle made of No. 5 PP can be used to hold hot water and can be used many times, but it is not recommended for long-term use.
No. 7 plastic container (other): PC, which is common among other plastics, can be used as a water cup. Basically, the water cups and space cups sold in the mall are mainly made of PC materials. The material used by the famous American brand Tupperware is also PC material. PC materials are non-toxic and generally able to withstand high temperatures of 130°C. However, the quality of PC produced by different companies, origins or different brands will vary. Some PC materials may have carcinogenic bisphenol A remaining in the production process. Therefore, most countries now prohibit the direct use of PC materials for infant products.
