In fact, there is no comparability between them, because PET and PP belong to two different blister materials with different material properties, so the blister boxes made with these two materials are also different.


Say from color for instance, the common color of PP material is white, black or instinctive quality (namely milky white), PP material inside thin slice blister is done not have transparent, the most transparent also is the kind of translucent milky white only; PET, on the other hand, is usually transparent and rarely black or white.


From the physical properties, PP material melting point as high as 167℃, is the only material can be put into the microwave oven heating blister, and can withstand the low temperature of minus 35℃, so PP blister packaging box is very suitable for containing cooked food, cold meat, seafood and other need to heat or need to refrigerate food; However, when heated to 70℃, the material of PET is easy to deform and produce substances harmful to human body. Therefore, PET blow-up box is suitable for filling fruits, vegetable salad and other edible things without heating.


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