SCHAUMSTOFF-PAPP-LAMINATE, DIESE ENTHALTENDE ARTIKEL UND HERSTELLUNGSVERFAHREN DAFÜR |
摘要 |
The present invention relates to foam-paperboard laminates (foam-paperboard laminates) prepared using an in situ foaming process. The foam-paperboard laminates of the present invention are formed by extruding LDPE polymer onto a moisture containing paperboard to provide a LDPE-coated paperboard material. Upon heating of the LDPE-coated paperboard, the moisture in the paperboard causes steam to act as a blowing agent for the LDPE and a LDPE foam is obtained. The foam is adhered to the paperboard by way of physical adhesion of the polymer to the paperboard. The foam-paperboard laminates of the present invention exhibit insulating and cushioning properties. The foam-paperboard laminates are suitable for use, for example, in insulating beverage cups, food service containers, packaging material, and in other products where laminates can be useful. |
