The number 1 indicates that the main manufacturing material is pet (polyethylene terephthalate), commonly used to make beverage bottles, heat 70 ℃, high temperature liquid or heating is easy to deformation, resulting in harmful substances melt, not suitable for recycling The

The number 2 is hdpe (high density polyethylene), suitable for cleaning supplies, bath products, can withstand 110 ℃ high temperature, but usually bad cleaning, into a hotbed of bacteria, it is best not to use.

The number 3 is pvc (polyvinyl chloride), mainly used for building materials, raincoats, etc., rarely used in food packaging, this material is easy to produce harmful substances at high temperatures.

Digital 4 for the ldpe (low density polyethylene), used in the manufacture of plastic wrap, plastic film and other products, heat resistance is not strong, more than 110 ℃ when there will be hot melt phenomenon, leaving some of the body can not break the plastic preparations, Physical into the microwave heating, first to remove the wrapped plastic wrap.

Digital 5 for the pp (polypropylene), resistant to 130 ℃ high temperature, is the only microwave can be put into the use of heating, can be reused after careful cleaning, but some microwave lunch box box made on the 5th pp, Pet or ps manufacturing, it can not be put together with the box into the microwave oven.

The number 6 for the ps (polystyrene), commonly used in the production of bowl made of instant noodles, fast food boxes, the material can not be placed in the microwave oven, can not be used to install strong acid (such as orange juice), strong alkaline substances, Decomposition of the human body is not good polystyrene.
