Abstract:
A deep drawing heat shrinkable multilayer film includes: an intermediate layer made of a vinylidene chloride copolymer resin (a); and a resin layer made of a first thermoplastic resin (b) layered on at least one surface of the intermediate layer. The multilayer film has hot water shrinkabilities in longitudinal and transverse directions at a temperature of 90°C range from 3% to 35% respectively.
Abstract:
A proposal is made for a la,bel (1) which can be adhered to an article (5), more particularly to a beverage bottle, and can be detached again in a washing liquid at a washing temperature of at least 50°C, in the form of a laminate at least with the following layers: a biaxially stretched polymeric film layer (9) which shrinks at the washing temperature, a printed decoration layer (11), and an adhesive layer (13), more particularly a pressure-sensitive adhesive layer, for adhering the label (1) to the article (5). The polymeric film layer (9) is designed in such a way that in the laminate at the washing temperature within a maximum time span of less than 5 minutes, in particular less than 3 minutes, it attains degrees of contraction in its two stretching directions which differ from one another by less than 50% and are preferably lower than 50%. As a result of this, whereas the adhesive force between the label (1) and the article (5) is high, the label (1) can be washed off from the article (5) without splitting.

PROBLEM TO BE SOLVED: To provide a heat-shrinkable cylindrical label, allowing adhesion to a small-diameter section by heat-shrinking and allowing formation of a good stereoscopic pattern after heat-shrinking.SOLUTION: A heat-shrinkable cylindrical label 3 of the present invention has a cylindrical body 5 obtained by forming a heat-shrinkable film 4 into a cylindrical shape and a resin layer 6 provided on a portion of the heat-shrinkable film 4 and laminated with a metal-containing layer 7, where the heat-shrinkable film 4 is a film having a heat-shrinkage ratio of 30% or more when heated to 85°C and having a shrinkage stress of 6.5 MPa or less when heated to 85°C; the resin layer 6 laminated with the metal-containing layer 7 is formed by coating the heat-shrinkable film 4 with an ultraviolet-curable resin-containing coating liquid and laminating a transfer foil on the surface of the coated film, followed by curing the coated film; and the resin layer 6 is a layer without substantial heat-shrinking and curing when heated to 85°C.
Abstract:
A heat shrinkable label comprises (A) a heat shrinkable film comprising at least one thermoplastic polymer, and (B) a curable adhesive comprising (1) at least one urethane (meth)acrylate resin having an average of about 1 to about 1.6 (meth)acrylate groups per resin molecule, (2) at least one tackifier, and (3) at least one photoinitiator, where the film has an ultimate shrinkage at 135° C. of at least 15%, and the adhesive has sufficient precure tack, wherein the loop tack of the uncured adhesive is at least 4.3 g/cm2. The heat shrinkable label is useful in high-speed industrial processes such as beverage container labeling.
