A method of wrapping an article such as a vehicle, the method comprises applying a wrapping film to a vehicle and locating a thermochromics material in, adjacent or proximate an area requiring post-heating, heating the wrapping film to effect a post-heating operation until the thermochromics material changes colour.

This invention relates to processes for collation shrink packaging of one or more items with a thermally insulating film, to films for such processes, to packages so made, and to methods for extruding such films. The one or more items packaged may be cans, bottles, pouches and other carriers of liquid or solids.

A method for applying a label to an electrical cable having an outermost sheath with convolutions defining alternating peaks and valleys, the method including attaching the label to the sheath. The label includes a label substrate, the label substrate includes an attaching side, the attaching side being attached through an adhesive; and the label attaches to the peaks and spans across the valleys and circumferentially wraps around the sheath.

The present invention bonds a label to an adherend with a heat-sensitive adhesive layer disposed therebetween, by sufficiently activating the heat-sensitive adhesive layer. Prepared is a label which comprises a label base and a heat-sensitive adhesive layer disposed on the back surface of the label base, wherein an ultraviolet-absorbing heating agent is contained in an area of the label base which at least includes the disposed heat-sensitive adhesive layer and/or in the heat-sensitive adhesive layer. Before or after the label is applied to an adherend, irradiation with ultraviolet is conducted to activate the heat-sensitive adhesive layer.

A heat-shrinkable polyester film comprising ethylene terephthalate as a main component, containing not less than 0 mol % and not more than 5 mol % of a monomer component capable of serving as an amorphous component relative to the total of a polyester resin component, and having a main shrinkage direction in a lengthwise direction, wherein the heat-shrinkable polyester film satisfies heat shrinkage characteristics of the width direction and the lengthwise direction and the molecular orientation angle difference which is a difference between a molecular orientation angle of an edge of one end in the width direction and a molecular orientation angle of an edge of the other end.
