Plastic packaging of hardware
Blister products plastic cover milk tea cover can be customized
The sheet material used for blister packaging is called hard sheet or film, commonly used are:
PET (polyethylene terephthalate) hard tablet
PVC (polyvinyl chloride) sheet
PS (polystyrene) hard sheet, PS hard sheet density is low, poor toughness, easy to burn, combustion will produce styrene gas (is a harmful gas), so generally used to produce a variety of industrial plastic tray.
PVC hard sheet toughness is moderate, not easy to burn, combustion will produce chlorine gas, cause a certain impact on the environment, PVC easy to heat, can use sealing machine and high frequency machine sealing edge, is the main raw material for the production of transparent blister products.
PET plate good toughness, high transparency, easy burning, burning does not produce harmful gases, belong to the environmental protection material, suitable for high-end blister products, blister blister of European and American countries generally require the use of PET plate, but it is not easy to heat sealing, bring great difficulty to the package, in order to solve this problem, people to adopt a kind of call of PETG glycol modified – polyethylene terephthalate material, as well as the material of PVC the ease of MWCNTS, also has a PET high environmental protection and transparency.
