METHOD FOR FABRICATING SHAPED PAPER PRODUCTS
A method for fabricating shaped-paper products is introduced herein, which comprises at least one dredging-pulp step for forming a wet pulp made of paper-slurry materials, at least one pre-compression step for lightly compressing the wet pulp to form a first semi-finished product, at least one thermo-compression forming step for deeply compressing the first semi-finished product to form a second semi-finished product, and a surface-coating step of employing a product surface coating apparatus to coat a liquid coating materials onto at least one outer surface of the second semi-finished product, and thereby forming each of the shaped-paper products having a binding layer. With utilization of the present invention, an automatic coating can be applied high efficiently in a series of continuous production machines. This could not only shorten processing time and benefit a mass production thereof but also ensure a higher production yield and quality.

COATING COMPOSITION FOR CORRUGATED PAPER BOARD
A coating composition for a corrugated paper board is described. The corrugated paper board includes an inner liner sheet and an outer liner sheet adhered to opposite sides of a corrugated medium. The coating composition includes a pre-coat layer and a topcoat layer. The pre-coat layer includes an ink fixer agent and a pigment, and is disposed on one or both of the liner sheets. The topcoat layer is disposed on top of the pre-coat layer to form an ink receiving layer. The topcoat layer includes a wax and is devoid of the ink fixer agent.

Soft creped tissue
The invention provides a creped tissue web having satisfactory softness without the excess use of water insoluble creping compositions. The satisfactory softness levels, which may be measured as TS7, are generally less than about 10.0 and may be achieved by creping the tissue web with less than about 100 mg/m.sup.2 (milligrams of creping composition per square meter of creping cylinder surface area) such as from about 25 to about 100 mg/m.sup.2 and more preferably from about 50 to about 75 mg/m.sup.2. It was previously believed that water insoluble creping compositions need to be added at high add-on levels, such as 100 mg/m.sup.2 or greater to achieve a desirable softness at a given tensile strength. It has now been surprisingly discovered that the add-on of water insoluble creping composition may be reduced significantly by adding a water soluble adhesive to the creping composition.
