Foldform label laminate

Abstract

A foldform label laminate includes a web having first and second bands laminated together along a longitudinal running axis by complementary patterns of release and adhesive disposed therebetween. The patterns of release and adhesive repeat along the running axis to define a series of repeating laminated sheets. The second band has a corresponding label disposed in each of the sheets. Each of the labels is removable from atop the first band, with the adhesive remaining on the label, and the release remaining on the first band.

Description

[0001] This application is a division of application Ser. No. 10 / 419,449; filed Apr. 21, 2003, which in turn is a continuation-in-part of application Ser. No. 09 / 775,998, filed Feb. 2, 2001, now U.S. Pat. No. 6,596,359.BACKGROUND OF THE INVENTION [0002] The present invention relates generally to label laminates, and, more specifically, to manufacturing thereof. [0003] The ubiquitous label laminate is found in various configurations for various uses, and is manufactured in various manners. The typical consumer label product is in the form of two-ply label sheet having multiple die cut labels removably bonded using pressure sensitive adhesive to an underlying liner coated with a release agent such as silicone. [0004] The liner is typically mass produced in large rolls and then subsequently laminated to a face sheet also provided from large rolls. The laminated face sheet is then suitably die cut to define the individual labels thereon, with the laminate typically being produced in a c...

AI Technical Summary

Problems solved by technology

Since the integrated form / label sheet includes the two-ply label laminate and the adjoining single ply form sheet, the manufacture thereof is correspondingly complex, with associated cost.

However, porous paper increases the difficulty of forming a suitable liner.

If the paper is porous and readily absorbs the liquid silicone, the cured silicone may not form a suitable release coating for the pressure sensitive adhesive of the laminated face sheet.

Since the liner and face sheet have different material compositions and thicknesses, they are subject to undesirable curling thereof due to changes in temperature and relative humidity.

Temperature and humidity cause the liner and face sheet to expand and contract differently from each other and leading to curl of the laminate which may cause misfeeding or jamming in typical printers.

These multiple processing steps correspondingly increase the cost of production as opposed to the edge-joined production method disclosed above.

Nevertheless, the multi-pass process typically results in the end product being more costly.
