This is because they absorb oxygen rapidly and in large quantities. Furthermore, the composition of the present invention can be molded by a well-known plastic molding method to form a container or packaging material.
For example, it is a film-like or sheet-like packaging material made by extrusion molding. This packaging material is used not only for manufacturing bags etc.
It can be used as a container lid, etc. A container can also be manufactured by extrusion molding into a vibrator shape, cutting both ends of the vibrator, and attaching a metal lid or the like. Moreover, the container can also be manufactured by an injection molding method or a blow molding method. Alternatively, after the product is first formed into a film or sheet, it can be formed into a cup-shaped or tray-shaped container by a drawing method such as vacuum forming, pressure forming, or plug forming. When making containers and packaging materials, it is desirable to mix a large amount of metal compounds, but this may place a heavy burden on the molding machine and reduce the strength of the resulting containers and packaging materials, so the molding method is not suitable. It is necessary to adjust the amount of metal compound mixed according to the conditions.
