摘要:
A method for fabricating a bubbler is disclosed, which is performed by laminating a polypropylene (PP), PE, CPET film onto a paper material surface to form a PP, PE, CPET film, and then screen printing or coating a hydrophilic polyurethane (PU) material onto another surface of the paper material to form a hydrophilic PU foaming material, then color printing a print material onto the hydrophilic foaming film to form a pattern layer, trimming the paper material to form a paper plate having a desired range, and forming the paper plate as an utensil, and enabling the hydrophilic PU foaming film to form a three dimensional pattern area on a surface of the utensil by being heated and thus foaming with a heating temperature presenting when the utensil is formed, whereby a three dimensional pattern area may be directly formed onto a surface of a utensil.

A method for making the paper board includes a step of pre-heating and the paper roll and removing static electricity from the paper roll by way of corona treatment; a step of pre-heating the bio-degradable material to be liquid status; a step of extruding the bio-degradable material to be foam type layer and coating the foam type layer on the paper roll; a step of cooling the foam type layer by cooling rollers which evenly press the layer on the paper board; a step of cooling the layer on the paper board by cooling rollers and treated by another corona treatment, and a step of cutting the paper board into desired sections.

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.
摘要:
A new coated fibrous substrate is produced by applying a coating containing swelled super absorbent particles having a minimum dimension of at least 5 microns to obtain the desired porosity and roughness in the finished coating, applying the coating to the substrate at least partially setting the coating thereafter driving at least the majority of the carrier absorbed by the super absorbent particles from the particles to leave macro-voids in the coating and produce a coated surface having a roughness in the macro as opposed to the micro range.
