METHOD FOR MANUFACTURING PAPER BUFFER TRAY FOR PACKAGING AND BUFFER TRAY MANUFACTURED THEREBY
20210095428 · 2021-04-01 · ·

The present invention relates to a method for manufacturing a paper buffer tray for packaging and a buffer tray manufactured thereby, wherein a plurality of papers are laminated and processed such that some papers are cut in a length direction, wrinkles or the like are formed in the other papers, and press-molding is performed using a mold, thereby providing an eco-friendly buffer tray and overcoming a disadvantage in that it is difficult to mold a buffer tray by using an existing paper. The method for manufacturing the paper buffer tray for packaging includes: a raw material preparing step of preparing a raw material for manufacturing a buffer tray in which a plurality of papers are laminated; a molding preparing step of preparing at least one mold corresponding to a shape and size of a product to be packaged; and a molding step of press-molding the raw material by using the at least one mold.

WOVEN BASE FABRIC WITH LASER ENERGY ABSORBENT MD AND CD YARNS AND TISSUE PRODUCT MADE USING THE SAME

A structured tissue belt assembly including a supporting layer, a non-woven web contacting layer, and one or more laser welds that attach the bottom surface of the web contacting layer to the top surface of the supporting layer. The structured tissue belt assembly allows for air flow in x, y and z directions. In exemplary embodiments, the structured tissue belt assembly has an embedment distance between the supporting layer and the web contacting layer of 0.05 mm to 0.60 mm and a peel force between the web contacting layer and the supporting layer of at least 650 gf/inch.

PAPER-SPECIFIC MOISTURE CONTROL IN A TRAVELING PAPER WEB
20210040696 · 2021-02-11 ·

A network-based system and method for providing desired moisture set point values for individual papers lines based on the physical properties of each liner and the atmospheric conditions associated with a corrugator is disclosed. The desired moisture set point values are based on the hygroexpansivity of each individual paper liner. Once the moisture set point value has been determined, a conditioning apparatus adjusts a moisture value for each liner in order to tune the post-warp characteristics of the final corrugated product.
