Only PVC, PET, PS and PP are common materials of blister packaging boxes. However, the production process of blister packaging box involves a problem of mold layout, that is, how many holes do the bulk mold mold, how to arrange the most appropriate. Each blister packaging box because of the size of the different mold layout method is not the same, then the size of the bulk mold after the layout will not be the same. The final material specification of the blister packaging box will be determined according to the size of the bulk mold laid out, and different blister packaging box material thickness is also different, even if the difference of 0.1mm for the blister packaging box material is a big gap oh. Therefore, it is very difficult to share materials between blister packaging boxes, unless the two blister packaging boxes are the same in the outer length, width and height, but the internal structure is unchanged, so that they can be Shared, but this situation in the blister packaging box industry is very rare.
