The difference between APET and PET

Polyethylene terephthalate (English: duPolyethylene terephthalate, zhi referred to as PET) is a common type of resin in life, which can be divided into APET, RPET, and PETG.


In the plastic classification, the code name of PET is No. 1, which has a wide range of functions:


Can be spun into polyester fiber, namely polyester


Can be made into film for use as substrate, insulating film, product packaging, etc. for audio, video, motion picture film, etc.


As a plastic, it can be blown into various bottles, such as cola bottles, mineral water bottles, etc.


Can be used as electrical parts, bearings, gears, etc.


Because of its low melting point, PET plastic bottles should not be filled with hot water, alcohol and grease, so as to avoid the precipitation of carcinogen DEHP.


Imported bottles have strict requirements on raw materials during production, and the bottle walls are thicker, so there is less hydrolysis in reprocessing and better whiteness.


Due to the lax standard control of domestic bottles, some use raw materials with lower viscosity, and some also use recycled materials.
