Introduction to plastic sealing
What are the plastic sheets commonly used in plastic packaging? What are the characteristics of each?
The sheet used for plastic packaging is called hard sheet or film. Commonly used ones are (polyethylene terephthalate) hard sheet
(polyvinyl chloride) hard sheet
( Polystyrene) hard sheet.
The hard sheet has low density, poor toughness, and is easy to burn. When burned, it will produce styrene gas (a harmful gas, so it is generally used to produce various industrial blister trays.
The hard sheet has moderate toughness and is not easy to burn. Burning, chlorine gas will be produced during combustion, which will have a certain impact on the environment
Easy to heat seal, sealing machine and high-frequency machine can be used for edge sealing. It is the main raw material for the production of transparent blister products.
The hard sheet has good toughness. It has high transparency, is easy to burn, and does not produce harmful gases when burning. It is an environmentally friendly material, but the price is high. It is suitable for high-end blister products. Blister blister shells in European and American countries generally require the use of hard sheets, but they are not easy to heat seal. , brings great difficulties to packaging. In order to solve this problem, people compound a layer of
film on the surface and name it
hard film, but the price is higher.
