Classification and marking of plastic products
04 - LDPE (low density polyethylene), plastic film, plastic film and so on are all of this material. Heat resistance is not strong, usually qualified PE cling film will appear in the temperature of more than 110 degrees of hot melt phenomenon, will leave some of the body can not be broken down the plastic preparations. And wrap the food with plastic wrap to heat it. The grease in the food easily dissolves the harmful substances in the preservative film. Therefore, the food into the microwave oven, it is necessary to remove the wrapped plastic wrap.
03 - PVC (polyvinyl chloride) according to reports, toxic and harmful substances to produce plastic products of this material from two aspects, one is not a single molecule of vinyl chloride is fully polymerized in the production process, two plasticizer harmful agent in. These two substances are easy to precipitate when they encounter high temperature and fat. Toxic substances enter the human body with food and cause cancer easily. At present, this kind of material has few containers for packing food. Never use it if it is in use.
02 - HDPE (high density polyethylene) bearing cleaning supplies, plastic containers, bath products currently used in supermarkets and shopping malls in the plastic bag is made of such material, resistant to high temperature of 110 DEG C, indicating the food use of plastic bags can be used for holding food. Bearing cleaning supplies, plastic containers and bath products can be repeatedly used after careful cleaning, but these containers are usually not good cleaning residue, the original cleaning supplies, become a breeding ground for bacteria, cleaning is not thorough, it is best not to use circulation.
01 - PET (polyethylene terephthalate) mineral water bottles and carbonated beverage bottles are made of this material. Dong Jinshi pointed out that the beverage bottles can not be recycled, hot water, this material is heat-resistant to 70 degrees, only suitable for warm drinks or frozen drinks, high temperature liquid or heating is easy to deformation, there are harmful substances dissolved. And, scientists have found that after 10 months, the plastic could release carcinogens that are toxic to humans. As a result, when a beverage bottle is used up, it is thrown away. It should not be used as a drinking cup or used as a storage container to hold other articles so as not to cause health problems.
05 - PP (polypropylene) microwave oven lunch box made of this material, resistant to 130 degrees high temperature, poor transparency, this is the only plastic box can be put into the microwave oven, after careful cleaning can be repeated use. Special attention is needed, some microwave oven box, box with 05 PP production, but the lid is to 06, PS), PS (polystyrene) good transparency, but not high temperature, so it cannot be put together with the box of microwave oven. For insurance purposes, put the container in front of the microwave oven and remove the lid first.
