The disclosure relates to a mechanically recyclable label () comprising a face () and an adhesive (). The face () comprises ethylene containing polymer and the adhesive () comprises pressure sensitive adhesive. The pressure sensitive adhesive comprises at least 15 wt. % of a base polymer, at least 25 wt. % of a tackifier and at least 10 wt. % of a plasticizer. The base polymer, the tackifier and the plasticizer are colourless and odourless. The base polymer is a styrene block copolymer. The mechanically recyclable label () is mechanically recyclable with packaging material comprising ethylene containing polymer. The disclosure further relates to a label laminate (), a method for manufacturing a label laminate (), a labelled item (), as well as to use of a label () and of a label laminate (). The disclosure also relates to use of a waste matrix of the label laminate for producing granulates of recycled plastic.

Recyclable plastic label

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&#xb0; C. in alkaline aqueous solution of at least 30% less than the peel adhesion at room temperature of 23&#xb0; C.&#xb1;2&#xb0; C. and relative humidity of 50%&#xb1;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.

Wash-off label, a combination of a wash-off label and an item

An indicator that reacts with at least one gaseous compound in such a way that the color of the indicator is changed. The indicator is a layer formed on a substrate and including metallic silver and/or metallic copper.
