Document Type and Number:
Japanese Patent JP2022169962
Kind Code:
A
Abstract:
To provide a paper laminate for foaming which has good foamability and is excellent in thermal insulation property when used as a cup, a paper cup for foaming, and a method for manufacturing a foam paper cup.SOLUTION: Foamability is remarkably improved by blending a low density biomass polyethylene resin with an outer surface polyethylene resin layer. A paper laminate for foaming includes a foam layer composed of a low density polyethylene resin having density of 0.91 g/cm3 or more and less than 0.93 g/cm3, a paper base material layer, and an inner surface polyethylene resin layer in this order, wherein the low density polyethylene resin contains a low density polyethylene resin having density of 0.91 g/cm3 or more and less than 0.93 g/cm3.SELECTED DRAWING: Figure 1
