List of recycling marks for plastic products
Serial number: 01
Material name: PET (polyethylene terephthalate)
Usage: beverage bottle of pure water, mineral water and carbonated drink.
Usage: no hot water.Heat resistant to 70 ℃.It can only be used once.
Hazard analysis: holding high temperature liquid or heating bottle will deform and melt out harmful substances.After 10 months of continuous use, carcinogens may be released, which is toxic to human body.It must be discarded after use. It should not be used as a water cup or as a storage container for acid solution or grease.
Serial number: 02
Material name: HDPE (high density polyethylene)
Product use: container and supermarket packaging bag containing cleaning products, bath products.
Using features: heat resistant to 110 ℃.Containing non - food substances can be reused.
Hazard analysis: the plastic bags used to mark food are best kept out of direct contact with food in order to prevent microbial contamination.If the residual liquid is not completely removed, it will still become a hotbed for bacteria. It is recommended not to reuse it repeatedly.
Serial number: 3
Material name: PVC (PVC)
Product use: and less used in food packaging.
Usage: high temperature and grease are forbidden when packaging food.Not to be used with heat.
Hazard analysis: reasons for the easy production of toxic and harmful substances: 1.2. Harmful substances in plasticizers.The above substances are easy to be precipitated when exposed to high temperature and oil, if food into the human body, easy to cause cancer.It is advisable not to use it for dress-up food.
Serial number: 4
Material name: LDPE (low density polyethylene)
USES: plastic film, plastic film
Using features: heat resistance is not strong, 110 ℃ hot melt.
Hazard analysis: the human body can not decompose due to hot melt.When food is heated by wrapping it in plastic wrap, the grease in the food dissolves the harmful substances easily.Accordingly, before food enters microwave oven, want to tear the wrap food to keep fresh film before can make heating treatment.
Serial number:5
Material name: PP (polypropylene)
Product USES: microwave dinner box, juice beverage bottle, cup
Using features: 130 ℃ high temperature resistance, transparency is poor, can be repeated use.
Hazard analysis: it is the only plastic container that can be put into microwave oven to heat food. It can be reused after cleaning.Special remind: the box body of some microwave oven meal box is made of 05PP, but the cover is made of 06PS which is not resistant to high temperature.
Serial number: 06
Material name: PS (polystyrene)
Product USES: bowl pack bubble noodle box, foaming fast food box
Usage: heat and cold resistant, but can not put in microwave oven to heat food.
Hazard analysis: high temperatures release chemicals and do not contain strong acids (such as orange juice) and alkaline substances because they break down polystyrene, which is bad for you.So, try not to pack hot food in a fast-food box.
Serial number: 7
Material name: PC (polycarbonate) and other types
Usage: milk bottle, water cup, water bucket
Usage: reusable, but avoid using damaged or aging containers
Hazard analysis: A small amount of bisphenol A may be released into food or beverage because it is not completely converted to the plastic structure of PC when producing PC products.The residual bisphenol A accelerated release with increasing temperature.So you can't hold hot water.If the container is damaged, it must be discontinued to prevent bacterial contamination.
