<p>#CMT# #/CMT# The film has a local region of extra thickness extending along a line of weakness to border the line of weakness. The line of weakness and an adjacent local region of extra thickness are provided together to define a tear line (10). The local region of extra thickness is constituted by applying liquid or semi-liquid material i.e. polymer varnish, to the film with a specific quantity based on expected shrinkage ratio in a portion of the film while a sleeve is heat-shrunk onto an article. The tear line extends around a closed outline. #CMT# : #/CMT# An independent claim is also included for an article covered by a heat-shrink sleeve. #CMT#USE : #/CMT# Plastic material film for heat-shrink sleeve of an article (all claimed) i.e. container. #CMT#ADVANTAGE : #/CMT# The region of extra thickness along the line of weakness in a heat-shrink sleeve is made using heat shrink film, thus preventing bifurcation of a tear. The material can be transparent or colored, and include inclusions such as pigments or flakes, thus providing an appearance effect or making the tear line easier to see. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a container covered in a heat-shrink sleeve. 1 : Container 2 : Heat-shrink sleeve 10, 20 : Tear lines 30 : Tear strip 32 : Grip tab.</p> |
