The present invention relates to a thermosensitive label for monitoring the quality state of a thermosensitive article. The present invention also relates to a preparation method of the thermosensitive label and a thermosensitive article using the thermosensitive label. The thermosensitive label according to the present invention comprises two laminated layers which are physically-separated of a thermosensitive function layer and an adsorption-indication function layer. The two laminated layers are stored and transported separately, and combined together in use.

For example, the indicator tag includes a three-dimensional mesh comprising a plurality of pores, wherein the three-dimensional mesh is printed with a water soluble and ultra-violet (UV) light curable ink, a container enclosing the three-dimensional mesh, a membrane coupled to the three-dimensional mesh, and a dye dispensed on top of the membrane, wherein the three-dimensional mesh interacts with the dye when in contact with the dye to provide an indication.

[Problem] To provide a heat-shrinkable polyester film having excellent shrink finishing property due to the film's sufficient heat shrinkability and low shrinkage stress in the longitudinal direction, small change in the non-shrinkable direction of the film.

[Solution] The heat-shrinkable polyester film which heat-shrinks in the longitudinal direction and satisfying the following (1) to (6); (1) having a shrinkage of 35% to 70% in the longitudinal direction; (2) having a shrinkage of −8% to 7% in the width direction; (3) having a change rate of 5% to 22% when fixed in the longitudinal direction with fixed-length; (4) having a change rate of 5% to 20% in the width direction when fixed with 10% of slack in the longitudinal direction; (5) having a maximum shrinkage stress of 5 MPa to 15 MPa in the longitudinal direction; (6) having a stress at 10% elongation, F10, of 1 MPa to 5 MPa in the longitudinal direction and 0.5 MPa to 3 MPa in the width direction.

A labeling arrangement (1) for frozen applications comprises a top label (10) having an adhesive layer (12) having a predetermined freezing temperature below 0° C. The labeling arrangement (1) further comprises a base component (20) having a base layer (21) and an interlocking structure (22) comprising a plurality of hook-shaped coupling elements (23). The hook-shaped coupling elements (23) each comprise a first and a second portion (231, 232) which are geometrically different such that the first portion (231) extends laterally beyond the second portion (232) with respect to a main lateral extension plane of the base layer (21), the second portion (232) being arranged between the first portion (231) and the base layer (21) and coupling the first portion (231) to the base layer (21). The adhesive layer (12) is adapted to be coupled to the interlocking structure (22) above the freezing temperature of the adhesive layer (12) such that they form a positive coupling at freezer temperatures below the freezing temperature of the adhesive layer (12) and a substantial coupling at temperatures above the freezing temperature of the adhesive layer (12).

A label comprising a body having a first side for attaching to a container and a second side for displaying information, the first side includes a releasable adhesive for attaching the label to a container, wherein the releasable adhesive is treatable to cause the label to be separated from the container, and at least a part of the body is heat sensitive such that the label curls towards the first side to conceal part of the releasable adhesive when the label is heated to hinder the label separated from the container from re-attaching to the container.

A flexible self-adhesive label comprising a radiation-sensitive indicator for a syringe, the syringe comprising a barrel part with a front part and a rear part, having a tip at the front part, a piston at the rear part, and an exterior surface with a marking thereon. The label is attached to at least one part of the syringe and does not overlap with the marking. Also disclosed is a labeling method, kit and dispenser featuring such labels.

The present invention provides a heat shrinkable multilayer film that can prevent layer misalignment at a center seal portion and thereby provide a labelled container having excellent appearance when the film is attached to a container as a heat shrinkable label for dry heat shrinking, and a heat shrinkable label including the heat shrinkable multilayer film as a base film. Provided is a heat shrinkable multilayer film including: front and back layers each containing a polyester resin; an interlayer containing a polystyrene resin; and adhesive layers, wherein the front and back layers and the interlayer are stacked with the adhesive layers interposed therebetween, and the heat shrinkable multilayer film has a maximum shrinkage stress of 3.5 to 11 MPa when immersed in hot water at 80° C. for 30 seconds.

The invention relates to an electromagnetic radiation blocking label arrangement and to a labelled item comprising said label arrangement. According to an embodiment the label arrangement comprises at least one label component including a shrinkable film and at least one metal deposition layer on a surface of the shrinkable film. The shrinkable film is uniaxially stretched so as to form shrinking capability for the film when exposed to an external energy.
