Manufacturing of Heat Insulating Paper Cup, Board and Container

Yu-Chang Su

Summary Structure and manufacturing of new heat insulation paper cups, board and containers are introduced. The structures of heat

insulation layer can be divided into three types, namely foaming layer type, two layer type and three layer type. And molded pulp heat

insulation paper cup are also discussed. Structure of molded pulp heat insulation paper cup is made of multiple layers of enclosed

foaming agent layer and high-density pulp layers on the outside.

The utilization fields and heat insulating characteristics of these products are listed. Comparison between polystyrene foam made

insulating products are also conducted.

Keywords heat Insulating paper cup, heat Insulating board, heat Insulating container, pulp mold
