The Raw Materials Of The Cup Making Machine

- Sep 12, 2018 -

The sheet for the cup making machine is called hard sheet or film. Commonly used are: PET (polyethylene terephthalate) hard sheet, PVC (polyvinyl chloride) hard sheet, PS (polystyrene) hard sheet. PS hard sheet has low density, poor toughness, and is easy to burn. It produces styrene gas (hazardous gas) when burned, so it is generally used to produce blister trays for various industrial cup machines. PVC hard sheet has moderate toughness, is not easy to burn, generates chlorine gas when burned, and has certain influence on the environment. PVC is easy to heat seal, and can be sealed by sealing machine and high frequency machine. It is the main raw material for producing transparent plastic products. PET hard sheet has good toughness, high transparency, easy to burn, no harmful gas when burning, and belongs to environmentally friendly materials, but the price is high, suitable for high-grade plastic products. The blister bulbs of European and American national cup making machines generally require PET hard. The film, but it is not easy to heat, which brings great difficulty to the package. In order to solve this problem, people put a layer of PVC film on the PET surface, named PETG hard film, but the price is higher.
