The invention relates to a wash-off label structure and an adhesive layer comprising a pressure sensitive hot melt adhesive layer sensitive to the washing conditions. According to an embodiment the adhesive layer comprises an acrylate composition curable with ultraviolet radiation and at least one modifier selected from a tackifier, a plasticizer and a filler, and wherein the peel adhesion from the labelled surface at 50-80° C. in alkaline aqueous solution of at least 30% less than the peel adhesion at room temperature of 23° C.±2° C. and relative humidity of 50%±5%. The invention further relates to a use of the label for recyclable or reusable packages, and a combination of a package and a wash-off label.

The invention relates to a facestock for adhesive label, an adhesive label and an adhesive label laminate comprising an uniaxially in machine direction oriented facestock. According to an embodiment core layer comprises the following components: propylene homopolymer; a modifier consisting of at least one of the following: olefin elastomer, olefin plastomer and olefin block copolymer; and low density polyethylene. Further the invention relates to a use of the adhesive label for labelling of an article.

To prevent an ink from discoloring and an ink from remaining when a tape for label writer using a transparent synthetic resin film which is colorized by an ink layer is peeled off from an adherend.

A tape for label writer being composed of: (i) the tape for label writer having a layer structure including at least a process layer, substrate layer, ink layer, barrier layer, and adhesive layer in this order; (ii) the substrate layer being a synthetic resin film; and (iii) the ink layer including one adhesive resin selected from the group including polyurethane resin, acrylic resin and polyester resin, and a pigment.

Compositions comprising complexes of 1-methylcyclopropene and α-cyclodextrin, and articles including the composition, are provided. Methods for using the compositions and articles in delaying the maturation of fruits, vegetables, and plants are also provided.

1) An HMPSA composition comprising: from 20% to 50% by weight of a composition of styrene block copolymers; from 35% to 65% by weight of one or more tackifying resins; and from 7% to 25% by weight of a plasticizer consisting of a composition comprising a stand oil of a vegetable oil.

2) A multilayer system comprising: an adhesive layer (A) consisting of said HMPSA composition; a printable support layer (B) adjacent to the adhesive layer (A); and a nonstick protective layer (C), adjacent to the adhesive layer (A).

3) The use of said multilayer system for the manufacture of self-adhesive articles.

Provided is a laminate and label for laser printing which are capable of preventing or reducing the occurrence of failure in printing by laser light irradiation. A laminate (1) is at least a laminate for laser printing, including a first layer (31) having a property of shielding against laser light, a second layer (32) having a property of absorbing the laser light, and a base material layer (33) which is optically transparent, which are stacked in the order named. The second layer (32) may have a thickness of not more than 15 μm, and may have a specific composition.

Provided is an adhesive composition for labels, including a salt of lysine and citric acid, and chitosan, a method of preparing the adhesive composition, an adhesive sheet including the adhesive composition, and an article including the adhesive sheet.

The invention relates to a removable adhesive composition and uses of the adhesive composition in different kinds of labels and label laminate applications. In addition, the present invention relates to a label and a label laminate containing the removable adhesive composition.

A label sticker is provided and includes: a base layer; a release layer coated on an upper surface of the base layer; a first surface material layer having a lower surface coated with a first glue layer and coated on or adhered to the release layer through the first glue layer; and a second surface material layer having a lower surface coated with a second glue layer and adhered to an upper surface of the first surface material layer through the second glue layer. The area of the second surface material layer is greater than the area of the first surface material layer. The label sticker. Therefore, glue residues left behind by a process of making the label sticker do not interfere with use thereof.

A plant label has a substrate and a permanent adhesive layer on a release liner. An identifier portion of the substrate and a tag portion of the substrate are defined by a detach line that enables the tag portion to be detached from the identifier portion. The tag portion has an adhesive deadener on the permanent adhesive layer, a strip of the permanent adhesive layer of the detachable portion free of adhesive deadener, and a tab having only adhesive deadener on the permanent adhesive layer that enables the tag portion to be detached from the identifier portion and from a container to which the label is affixed.
