Abstract: A stretch sleeve label for attachment to a container is provided. The label contains at least one point of weakness configured so that the label can be easily removed by beginning to separate the label into pieces at or near the point of weakness. When removed at the point of weakness, the label is removed without any substantial portion of the label or any adhesive on the container.

Abstract: A resealable envelope comprising a flexible plastic back sheet, a backing adhesive applied on a back surface of the flexible plastic back sheet to attach the envelope to a package, a flexible plastic front sheet attached to the back sheet at their respective side edges and bottom edges, a flexible closure flap being adhered directly to the front surface of the back sheet at their respective top edges via a permanent adhesive and overlapping said front sheet, and a resealable adhesive located proximal to the top edge of the front sheet such that the resealable adhesive is capable of fastening said closure flap to the front sheet forming a resealable closure.

Abstract: The invention relates to a method and an apparatus for measuring the degree of evaporation of water through the skin, in which method a measurement chamber (20) is placed on the surface of the skin. In a method in accordance with the invention the measurement chamber (20) is a chamber which is open only at one side, and when placed on the skin it will become a totally closed chamber. During the measurement the vapour pressure is determined only in one point of the chamber. The degree of evaporation is determined by vapour pressure gradient in relation to time. In apparatus in accordance with the invention the measurement chamber (20) is open only at one side, and when placed on the skin it will become a totally closed chamber. Furthermore, there is a humidity sensor (21) in the measurement chamber for measuring the vapour pressure in one point of the measurement chamber.
