Blister packaging material is the main raw material of packaging production, after the production of a whole piece of product will be a single small product, and then will leave some products of the side material generally do not know how to distinguish often confused, this article to share let everyone know more about the blister packaging industry more understanding of materials. Materials commonly used in blister packaging plants are PP, PET, PVC, PE and so on.

1.PP material features: good soft toughness, environmental protection and non-toxic, relatively high temperature resistance, poor plasticity, difficult to blister, lack of luster on the surface, showing a matte color

Sensory identification: This product is white and transparent compared with LDPE higher transparency, kneading when sound.

Combustion identification: when burning, the flame is yellow and blue, the smell is like oil, the melt drops, and there is no black smoke when burning.

2.PET material characteristics: This material is an environmentally friendly material, the hardness of the material is good, the transparency is strong, and the surface of the material is bright.

Sensory identification: This product is white and transparent, feel hard, kneading when sound. Looks like PP.

Combustion identification: there is black smoke when burning, the flame has the phenomenon of jumping fire, the surface of the material after burning is black carbonized, the finger rub the black carbonized matter after burning, the carbide is powdery.

3.PVC material characteristics: is one of the most used materials in blister packaging, moderate price, strong toughness, good plasticity, such as low temperature weather will become brittle, easy to break.

Sensory identification: The appearance is very similar to EVA but elastic.

Combustion identification: when burning black smoke, out of the fire, the burning surface is black, no melting dripping phenomenon.

4.PP+PET material characteristics: This material is a composite material, the surface is close, wear-resistant, good plasticity.

Sensory identification: the appearance is like PP, the transparency is very high, and the sound is greater than PP when kneading.

Combustion identification: there is black smoke when burning, the flame has the phenomenon of jumping fire, and the burning surface is black carbonized.

5.PE+PP copolymer: There are low density, medium density, high density polyethylene, soft feel, this material is less used. Sensory identification: Compared with LDPE, the transparency of this product is much higher than LDPE, the feel is no different from LDPE, the tear test is very similar to PP film, the material is transparent and pure white.

Combustion identification: The flame of this product is all yellow when burning, melting dripping, no black smoke, smell like oil.
