Abstract: A new package or box type having an internal core or frame structure comprising of plastic or other polymer material sandwiched between two cardboard sheets an all sides of the box forming the outer walls of the box. The walls of the box containing the frame structure are more resistant to bursting or crushing than conventional corrugated cardboard used in the industry for transporting goods. Use of plastic or polymers applied to the core frame results in less material consumption than conventional corrugated cardboard. This invention yields higher package strength throughout the package structure and not just the edge of the package in order to negate the use of the double corrugated walls design as widely used in corrugated card board to achieve similar package strength quality while minimizing package weight and preserving exterior package composition of cardboard for handling purposes.
