Raw material for blister packaging

The plastic sheets used in blister packaging factories are called sheets or films. Common ones are:
   PET (polyethylene terephthalate) sheet
   PVC (polyethylene) sheet
   PS (polyethylene) sheets and PS sheets have low density, poor elasticity, and are easy to ignite. When ignited, they produce butadiene vapor (a hazardous substance), so they are generally used to make various industrial-grade blister trays. .
PVC sheets have moderate elasticity and are not easy to ignite. When ignited, they produce hydrogen gas, which causes certain harm to the environment. PVC is easy to melt. Automatic sealing machines and high-frequency machine wrapping can be used, which is the key to making transparent blister products. raw materials.
   PET sheets have good ductility, high clarity, and are easy to ignite. They do not produce harmful substances when ignited. They are new environmentally friendly materials, but they are expensive and suitable for high-end blister products. European countries generally require the use of blister bubbles. PET sheet, but it is not easy to melt, which brings great difficulties to packaging. In order to solve this problem, we choose a material called PETG glycol modified material-polyethylene terephthalate. Similar raw materials have the hot meltability of PVC and the high environmental protection and clarity of PET, but the price is higher.
