Plastics used in everyday life can be divided into 7 categories, each with different characteristics and applications. Today I will introduce you to plastic products and reveal their true face!
Plastic №1Used and discarded plastic
Plastic #1 is raw material for mineral water bottles, and its main ingredient is phthalate, which is cheap. easy to obtain, but it is not heat resistant and can warp at temperatures above 80 degrees Celsius.
Plasticizer is an important additive in production of mineral water bottles. Its main component is phthalic acid, which is highly carcinogenic.
Expert alert
Disposable plastic mineral water bottles should be discarded after use.
Synthetic materials are unstable, easy to decompose and release toxic substances after long-term use, which is harmful to human health.
Plastic №2Reusable plastic
Plastic No. 2 is the raw material for making shower gel and shampoo. Its main component is polyethylene which is extracted from oil and passed through high temperature and pressure, high density, very durable reusable.
Plastic №3The most dangerous plastic
Plastic #3 is widely used. Adhesives and garbage bags in everyday life, plastic greenhouses and rubber pipes used in agriculture are plastic No. 3. Its main component is polymer. Vinyl chloride, this ingredient has good performance, wear resistance and acid resistance, but disadvantage is not heat resistance and high toxicity.
Expert alert
Polyvinyl chloride causes angiosarcoma of the liver very easily, and large amounts of plasticizers, antioxidants and other additives are added to plastic #3.
It is not recommended to use food in plastic bags made from No. 3 plastic. These plastic bags are often used in breakfast stores, and it is difficult to prevent a health hazard!
Can you tell good plastic bags from bad ones?
Plastic #4Most flexible plastic
Plastic No. 4 is a raw material for making polyethylene film, and its main component is also polyethylene, but unlike plastic No. 2, it is in > Manufactured under normal pressure. non-toxic and harmless propylene and styrene are added to increase flexibility of plastic #4, so that polyethylene film from it can be safely used.
Expert alert
If a PE film is labeled PE (polyethylene), it means that it is not resistant to high temperatures and it is labeled PVDC (dichloroethylene ) >This is a high temperature polyethylene film that can typically withstand high temperatures of 150 degrees Celsius and can be used for microwave heating.
Plastic #5Most heat-resistant plastic
Plastic No. 5 is resistant to high temperatures and is raw material for making plastic cups and plastic lunch boxes. Its main component is polypropylene, which basically does not contain other additives, can be used for placement of food, microwave heating.
#6 plasticHigh temperature resistant disposable plastic
Plastic No. 6 is raw material for making disposable cups. Its main component is polystyrene, which is resistant to high temperatures. withstands up to 110 degrees Celsius, but low durability, recommended to be discarded after one use.
№7 plasticThe safest plastic
Plastic No. 7 is raw material for making space cup. Its main component is carbonate, which has a stable structure and fewer additives. durable> It is currently considered safest plastic.
Expert alert
Boiling hot water can decompose toxic substances in space cup. It is recommended that you try not to pour hot water into space cup to reduce chance of harm to your health.
Synthetic plastics are unstable under certain circumstances, so it is recommended to reduce their use. In daily life, it is recommended to use cloth bags, paper bags, porcelain or glass products ~ this can not only protect environment, but also benefit your health!
