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
