A label (20) may have a facestock (21). A direct thermal coating layer (21A) may be on the facestock (21), the direct thermal coating configured to selectively darken or change color by heat activation when direct thermal printed. A layer of adhesive (22) may be provided, the direct thermal coating layer (21A) being between the facestock (21) and the layer of adhesive (22).

Disclosed are a label film including a hidden pattern that is displayable through scraping a surface thereof and a manufacturing method thereof. A concealment scraping layer printing ink is formed by mixing, in respect of volume ratio, 1-10% nitrocellulose, 5-15% polyamide resin, 20-30% silver paste, 5-15% pearl powder, 10-20% ethyl acetate, 20-30% toluene, and 5-15% isopropyl alcohol and applied with intaglio printing such that a displayable mark formed of a traditional printing ink and including at least one pattern, character, or mark and at least one concealment scraping layer pattern formed with the concealment scraping layer printing ink are combined together and collectively formed on and attached to at least one surface of a single-layer label film substrate, with the concealment scraping layer pattern set on and covering at least one displayable mark, followed by steps of slitting, bonding, and cutting, to form a label film having at least one concealment scraping layer pattern covering and concealing at least one displayable mark through a combined printing operation.

The present method relates to a manufacturing process of container labels with heat transfer technology, wherein alphanumeric codes are sequentially applied over, between and/or under the layers of specific inks and varnishes which protect said area of eventual friction and wear to which they are subject during transportation, handling and productive tests.

The present application relates to a method for manufacturing an indicator for food that can visually check the quality change in food in a package state, an indicator for food manufactured therefrom, and a method for checking the storage status of food using the same. The manufacturing method of an indicator for food of the present application includes bonding a first film, on which an indicator layer including a pH-sensitive indicator is formed on one surface thereof, and a second film, on which an adhesive layer is formed on one surface thereof, so that the indicator layer of the first film and the adhesive layer of the second film can face each other.

The present invention relates to a planar sealing element (1) for application to a substrate (2), comprising a carrier layer (3) and several functional layers (4), the functional layers (4) comprising at least one colour display layer (5) and an adhesion-controlling layer (6), the sealing element (1) furthermore comprising an adhesive layer (8) for attachment to the substrate (2), the functional layers (4) being arranged between the carrier layer (3) and the adhesive layer (8), wherein the carrier layer (3) is at least partially detachable from the functional layers (4) in order to bring the sealing element (1) from a first state (9) to a second state (10), with the second state (10) not being convertible into the first state (9), the sealing element (1) in the second state (10) comprising a peeled-off layer (11), comprising at least the at least partially detached carrier layer (3), and a residue (12), comprising at least the adhesive layer (8) and at least parts of the at least one colour display layer (5), the carrier layer (3) being made of paper, wherein it is envisaged, according to the invention, that the carrier layer (3) is translucent so that the peeled-off layer (11), in at least one area when the peeled-off layer (11) is arranged congruently on the residue (12), has a different colour impression than the same area of the carrier layer (3) in the first state (9) in a viewing direction toward the carrier layer (3).

A multi-purpose sticker for decorating and sealing an envelope and also for attaching the sealed envelope to a package, such as a gift. The multi-purpose sticker generally includes a double-sided adhesive layer hidden below a decorative covering. With the decorative cover in place, one side of the double-sided adhesive of the sticker can be used to seal an envelope, and the sticker serves as a decorative sticker. If desired, the decorative cover can be peeled off to expose an adhesive in order to affix the sealed envelope to a package.

The present invention refers to a manufacturing process of packing labels with Heat Transfer technology, wherein alphanumeric codes are sequentially applied over, between and/or under the layers of specific inks and varnishes which protect said area of eventual friction and wear to which they are subject during transportation, handling and productive tests.

A tamper evident label flap positioned to cover an opening in a package. The label flap includes a base layer having a top surface and a bottom surface. A top layer is attached to the base layer by an adhesive layer. A tamper evident structure is located in at least one designated area between the base layer and the top layer. The tamper evident structure includes a first ink layer applied to the base layer and a second ink layer applied to the first ink layer. The first ink layer and the second ink layer are held together in a weaker bond than a bond between the top layer and the base layer. When the label flap is initially pulled from the package, the first ink layer and the second ink layer separate and define a visible permanent de-lamination which signifies the package has been opened.

An epoxy sticker facilitating large area production and having an excellent three-dimensional effect by first forming a print line along the shape of a print part and then carrying out epoxy printing on the inside of the print line, and a method for producing the epoxy sticker.
