Pet blister is divided into PET-G and pet-a, which are actually two varieties of PET sheet. The softening point of the sheet is different. The softening point of PET-G is a little low, and the heat sealing temperature of pet-a sheet is more than 160 degrees, and the heat sealing temperature of pet-a sheet is more than 180 degrees. Since pet blister naturally uses pet blister oil, the skill is very simple, which is to control the coating amount of the blister oil, pet blister oil In fact, it's a general-purpose plastic oil. Pet can be used if it can use PVC. Otherwise, it's not necessarily. So it's necessary to choose the right plastic oil. Since it's the environmental protection film of pet, it should choose the water-based PET plastic oil.
With the development of science and technology, we have produced high-frequency machines for pressing APET at a price of about 20000-50000 (the production of hot pressing dies is also different). The ordinary high frequency (high frequency machine) of PETG can be welded, but the price of PETG material is 80% higher than APET material.
