る。 Saturated polyester bottles with biaxially stretched bottle bodies are used for cosmetics because they are non-toxic and have superior moisture and gas barrier properties compared to molded products made of other synthetic resins. It is widely used as a glass container in containers, food containers such as liquid seasonings, pharmaceutical containers, etc.
In order to store the contents of foodstuffs, medicines, etc. in a stable state over a long period of time, containers do not have sufficient gas barrier properties, especially oxygen gas barrier properties, and the surface hardness is extremely low. Containers also tend to rub against each other during transportation work or filling work, resulting in scratches on the outer surface of the container wall, which also has drawbacks such as lowering the commercial value.
