A special substance "crystal" that affects the transparency and feel of the plastic bag.
Crystal type openers are classified into "heavy" and "light" depending on the source. Heavy crystal refers to a natural mineral opening agent. Light crystal refers to an open agent chemically synthesized. The difference between the two is that there is a significant difference in weight at the same volume. Or at the same weight, there is a significant difference in the total amount of open-cell effective particles. Light opening agent, in the case of the same added weight, because the total amount of the opening agent particles is far more than the mass opening agent, the efficiency is much higher than the heavy opening agent. Therefore, the amount of addition can be reduced, the total transmittance of direct light is improved, and the transparency of the plastic bag is further improved.
