Bubble Pack Adds New Favorite

With the rapid development of the packaging industry, people have strict requirements on the plastic film used for pharmaceutical blister packaging: they must be thin and have enough barrier properties, but also be easy to tear but not easy to crack and high transparency, the drug at a glance. Therefore, pharmaceutical companies are very careful about choosing blister packaging materials. PP is a partially crystalline plastic. PP in the production process, after biaxial stretching, it will be in a high elastic state, when heated, the crystal lattice will be destroyed, so that the film shrinks significantly. In addition, during the production process of PP sheet, the degree of stretching is reduced to zero. Since the crystal inside is very small, if the quenching technology is used, the unfavorable production of the plastic can be avoided.
