Abstract

This product is formed by press molding of cardboard base paper and is mainly used as a container for storing food and other items. Numerous wrinkles are formed on the side walls and flanges. The wrinkles formed on the flanges are flatter than those formed on the side walls. This improves the top sealing performance when a lid material such as a top seal film is used to seal the flanges.
