A label is provided with a warning layer coating integrated or applied to a front side of the label. The warning layer coating is not activated by application of heat; rather, the warning layer coating activates upon a directional force (vertical or horizontal pulling) applied to the label after the label was initially adhered to a container, bag, box, and/or object. Upon activation, visible color or a printed warning indicia is visible on a front surface of the label, providing evidence that the label was removed after initial application or providing evidence that the label was attempted to be removed after initial application.

Provided is a method for marking a product for human or animal use with an XRF identifiable mark, the method including forming on at least a region of the product a pattern of at least one FDA-grade material identifiable by XRF, the pattern being optionally at least partially invisible to the naked human eye and having a predefined identifiable characteristic, wherein the product is selected from food products, therapeutics and cosmetics.

A dissolvable produce washing label includes a dissolvable substrate impregnated with a produce cleanser; an adhesive layer; and a coating to seal and protect from water and humidity. When rubbed and washed with water by the end user the top coating wears and breaks to expose the dissolvable substrate, thereby dissolving the substrate and releasing the produce wash.

A label with a microchannel for venting a package.

An article includes a tag and an elastic mechanism. The tag includes a front surface, a rear surface, first and second ends, a first fold defining a first bent portion, and a central span. The rear surface of the first bent portion is configured to face the rear surface of the central span. The elastic mechanism is secured to the first bent portion, wherein a first connection zone between the elastic mechanism and the first bent portion includes a first elastomer portion that extends along the rear surface of the first bent portion, extends around the first end, and includes a second elastomer portion that extends along the front surface of the first bent portion. An article strip includes a plurality of tags and a plurality of elastic mechanisms. Adjacent tags are separated by a weakened demarcation. A method of forming a plurality of articles is also described.

To provide a display medium that is discolored in a state of being exposed in the presence of oxygen. This display medium has a discoloration layer on a substrate, the discoloration layer being formed with a redox dye, a food dye, a reducing sugar, an edible reduction promoter, an edible moisturizer, and an oxygen detection composition that contains an edible thickener. The oxygen detection composition that forms the discoloration layer is reversibly discolored in accordance with the presence of oxygen, so that the discoloration layer changes color upon transition from an oxygen-free state to an oxygen-present state. Therefore, when the discoloration layer is formed with a letter, a drawing pattern, a symbol or the like, information relating to a commodity constituted by the letter, drawing pattern, symbol or the like is highlighted by discoloration.

A preparation method and an application method of a multifunctional intelligent cellulose-based visual label are provided. The multifunctional intelligent cellulose-based visual label solved a problem that an existing freshness indicator film is narrowed in an indication range. The preparation method includes the following steps: step 1 of carboxylation modification; step 2 of cationic grafting; step 3 of preparation of a composite dye solution; step 4 of preparation of responsive fibers; and step 5 of performing vacuum filtration to prepare paper, thereby obtaining the multifunctional intelligent cellulose-based visual label. The food freshness is indicated with the obtained intelligent visual label. An indicated pH value range is 4-8, color variation can be completed within 30 seconds, and the food freshness can be accurately indicated. The multifunctional intelligent cellulose-based visual label is low-carbon, efficient, green, safe, and wide in the indication range, and can be used in food monitoring.

The present invention provides a label facestock film comprising a substrate web and a pattern of active material on a surface of the substrate web, wherein the substrate web comprises one or more label-forming regions and one or more matrix regions, and wherein the pattern of the active material is repetitive and forms a region of said surface that is free from any active material, wherein said region at least partially overlaps with one or more of the one or more matrix regions.
