Methods for applying a liner-free, or liner-less label, to a substrate, particularly glass or plastic (e.g., PET) substrates are described herein. The method includes applying an adhesive composition, such as a polymeric coating, to a label face sheet, activating the adhesive composition with an activating fluid, and contacting the label to the substrate. The activating fluid is preferably a mixture of water and one or more organic solvents, such as low molecular weight alcohols. In some embodiments, the labels exhibit a percent fiber tear greater than about 50, 55, 60, 65, 70, 75, 80, 85, 90, or 95% after one, two, three, four, or five minutes. In particular embodiments, the labels exhibits a percent fiber tear greater than 60, 65, 70, 75, 80, 85, 90, or 95% after two minutes.

Fluid activatable adhesives for glue-free, liner-free labels for glass and plastic substrates and methods of use thereof

A reusable, liner-free labeling system, which allows labels to be wound without the use of a release liner, is described herein. The absence of a liner reduces inventory requirements, roll-changeover time, cost of production, and waste. Additionally, the labeling system described herein provides labels that remove cleanly, which reduces the time required to remove the label and eliminates the necessity of cleaning the substrate after removal. The labeling system provides labels that can be easily reused and reapplied, which can reduce time and costs associated with user labeling error. The labeling system is compatible with labels of all currently available facesheets, regardless of composition or physical characteristics, and allows for large quantity batch printing. The implementation of the labeling system does not require any changes to the pre-existing label printing infrastructure.

Two-component hybrid labeling system for use in repeat labeling

Methods for applying a liner-free, or liner-less label, to a substrate, particularly glass or plastic (e.g., polyethylene terephthalate) substrates, are described herein. The method includes applying an adhesive composition, such as a polymeric coating, to a label face sheet, activating the adhesive composition with an activating fluid, and contacting the label to the substrate. The activating fluid is preferably a mixture of water and one or more organic solvents, such as low molecular weight alcohols.

Fluid activatable adhesives for glue-free, liner-free, labels for glass and plastic substrates and methods of use thereof

Fluid activatable adhesive compositions and activating fluid(s) for activating the adhesive composition are described herein. The adhesive compositions contain at least two polymers with different hydrophilicities. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate. The adhesive composition may contain particulate fillers which enable fast exhaustion of the activation fluid out of the adhesive when applied to a substrate, thereby allowing the hydrophobic polymers of the adhesive composition to achieve strong adhesion of the liner-free label to the paper or polymeric substrate. The particulate fillers may also function as anti-blocking agents when liner-free label media are tightly wound in a roll. The adhesive compositions described herein may be used not only on paper, cardboard, and metal, but also on glass and plastics commonly used in commercial applications.
