Embodiment

[0027] Mark the AAA batteries with tabs with a maximum 2mm overlap at the seams. The label contains a pressure sensitive adhesive. There are three different types of membranes, namely polyvinyl chloride membranes (PVC), polystyrene-containing membranes and polyolefin membranes. The marked cells were kept at a temperature of 71° C. for one week, after which they were evaluated. The results are shown in Table 1.

Abstract

A battery label including an oriented face film having a front side and a rear side, and an adhesive layer on the rear side of the face film. The face film is a co-extruded multilayer film including at least one layer which includes a styrene-containing polymer. A battery includes a body and a battery label which is wrapped around the body.

Description

technical field [0001] The present invention relates to a battery label and a battery including a main body and the battery label. Background technique [0002] Uniaxially oriented rigid polyvinyl chloride (PVC) film is ideal for pressure sensitive battery labels. However, due to the nature of PVC, these films are considered environmentally harmful due to the problems associated with handling PVC films. Therefore, it is desirable to obtain alternative materials. [0003] Publication WO2004 / 072930 discloses a shrinkable battery label comprising a polymer base film and a first pressure sensitive adhesive for bonding the label structure to the battery substrate. The polymer base film is preferably a polystyrene film and has a thickness between 0.01 and 0.05 mm. The base film is covered with a transparent polymer top film. The top film is bonded to the base film by a transparent second adhesive. [0004] A problem associated with pure polystyrene films in the production of ...
