摘要:
In the manufacture of integrated labels it is desirable to apply pressure sensitive adhesive in a continuous manner, yet it is undesirable for active adhesive to be on one or more edges of the form since active adhesive can interfere with nip rollers upon entering a laser or other non-impact printer, or can otherwise interfere with proper operation of the printer. By using an adhesive--that is de-tackified by direct exposure to a sufficient type and dosage of electromagnetic radiation (such as a hot melt adhesive de-tackified by applying about 3000 mJ/cm.sup.2 total dosage of ultraviolet radiation)--that problem may be avoided. Apparatus for producing integrated labels with the adhesive at one or more edges being de-tackified may include a first conveyor for conveying sheets (either in stacked or single sheet form) in a first direction, and at least one ultraviolet radiation source mounted adjacent a side of the conveyor parallel to the first direction. A stacker, packaging device (such as a shrink wrap machine), 90.degree. conveyor, and/or turn table may also be utilized.

A thermal printer prints linerless labels in such a way that printer components will not stick to the adhesive face of linerless labels. Substantially stationary printer components, such as a label guide, transport plate, front panel, and stripper blade, preferably have the adhesive face engaging surfaces thereof plasma coated so that adhesive will not stick to them. An optional cutter provided downstream of the stripper blade also has plasma coated surfaces. A driven platen roller has a surface thereof coated with or covered by a high release silicone, which will not stick to the adhesive, but has high friction characteristics to facilitate drive of the labels. In a direct thermal printer, a plasma coated tear off surface is downstream of the driven platen roller, and stripper belts, a second roller with O-rings, and the like are provided to prevent the labels from wrapping around the driven platen roller. One or more sensors may also be provided for controlling drive of the platen roller in response to the position of registration marks on the linerless labels.
摘要:
An anti-blocking composition including about 75% to about 99% weight percent a metal salt of stearate and about 1% to about 25% weight percent stearic acid is provided. In addition, an anti-blocking composition including about 90% to about 99.5% a metal salt of stearate and about 0.5% to about 10% fiber is provided. The anti-blocking compositions may be formed into blocks and applied to a web of paper to reduce adherent properties of the paper. Further, a method of improving the handling properties of paper cut from a web is provided. The method includes the steps of coating a surface of a web of paper with an effective amount of a coating composition of the present disclosure, and cutting the web into sheets of paper.

A combined business form/identification card includes a sheet of cellulosic stock material having a barrier coating on a first portion of the sheet with an overlay of laser-printable varnish on the barrier coat. Lines of weakness are provided in the sheet in the area of the barrier coat and varnish to produce an identification card detachable from the sheet. A second portion of the sheet has indicia imaged thereon.
