The cosmetic packaging material factory talks about the reasons why cosmetic glass bottles are easy to break

Is the easy breakage of cosmetic glass bottles a particular concern for pharmaceutical companies? The cosmetic glass bottle is mainly because the material of the glass bottle contains silicon dioxide. The silicon atoms and oxygen atoms in the silicon dioxide are arranged in a spatial structure. You can think of it as a polyhedron. For this kind of material whose atoms are arranged in a spatial structure, their ability to withstand pressure is generally strong, but their ability to resist impact is weak, and they are particularly fragile when subjected to a strong impact force (for example, when they are dropped to the ground). As a counter-example, for metal sheets, their atomic arrangement is mostly in a layered structure, which has weak resistance to pressure and is easily deformed, but it has strong impact resistance and will not break no matter how much it is broken.

If there is more silica in cosmetic glass bottles, it will be fragile, but silica is an important raw material to form glass bottles, and it also contains the most content in glass bottles, which cannot be changed. Now glass bottles are added with a chemical raw material of boron oxide. Although glass bottles are fragile to some extent, they are still far inferior to plastic and metal materials in impact resistance.

Cosmetic glass bottles are available in a variety of materials, including cosmetic soda lime glass, low borosilicate glass, neutral borosilicate glass and high borosilicate glass, neutral borosilicate glass and high borosilicate glass. Relatively speaking, the impact resistance is better, but it is still far from enough. Now that the social industry is so developed, cosmetic glass bottles still cannot get rid of the shortcomings of fragility.
