Which PET and PP blister packaging will be better?

The same is used for food packaging boxes, then PET and PP blister packaging box which is better?


In fact, 2 of them are not comparable, because PET and PP are two different kinds of plastic materials, the properties of each material are different, then the plastic cartons made with these two kinds of materials are different.


For example, from the color, the PP material is usually white, black or native (milk white). In the thin film, the PP material is not transparent, and the most transparent is only the translucent milk white; and PET is the only transparent color, rarely used in black or white.


In terms of physical properties, the melting point of PP material is up to 167 degrees centigrade. It is the only plastic material that can be put into the microwave oven, and it can also withstand the low temperatures of 35 degrees centigrade. So the PP plastic packaging box is very suitable for food, such as cooked food, cold meat, seafood and so on. And the material of PET is heated to 70. Centigrade is easy to deform, and will produce harmful substances to the human body, so the PET plastic box is only suitable for food, vegetable salad and other things that do not need to be heated.


To sum up, there is no best blister box, only the most suitable blister packaging.
