MODIFIED POLYPROPYLENE CORRUGATED CARDBOARD

摘要

PROBLEM TO BE SOLVED: To provide plastic corrugated cardboard with a deep drawing shape and a complex shape formed exactly by molding a modified polypropylene sheet by vacuum forming. SOLUTION: The corrugated cardboard 1 comprises a core material 2 and a coating material 3 applied on one side or both sides of the core material 2. At least the core material 2 is produced by vacuum-forming a sheet of the modified polypropylene prepared by compounding 5-30 mass% of polyethylene and/or an ethylene-propylene copolymer into polypropylene.
