Title (EN) PACKAGING FILM WITH WEAKENING LINE AND SUPPORT COATING
(FR) FILM D'EMBALLAGE MUNI D'UNE LIGNE D'AFFAIBLISSEMENT ET D'UN VERNIS DE RENFORT
(DE) VERPACKUNGSFOLIE MIT SCHWÄCHUNGSLINIE UND STÜTZLACK
Abstract:
(EN) In order for it to be possible for a packaging film with a weakening line (8) to be straightforwardly wound up and unwound, provision is made for a support coating (11) to be applied at least in part, on the side (10) of the packaging film (1) with the at least one weakening line (8), in the region alongside the weakening line (8) and on either side of the weakening line (8), this compensating, at least in part, for the difference in thickness produced by the convexities (9).
(FR) L'invention vise à permettre d'enrouler et de dérouler aisément un film d'emballage muni d'une ligne d'affaiblissement (8). A cet effet, un vernis de renfort (11) est appliqué au moins en partie sur la face du film d'emballage (1) munie de ladite au moins une ligne d'affaiblissement (8) dans la zone située à proximité de la ligne d'affaiblissement (8) et des deux côtés de ladite ligne d'affaiblissement (8), de sorte à compenser au moins en partie la différence d'épaisseur due aux parties bombées (9).
(DE) Um eine Verpackungsfolie mit einer Schwächungslinie (8) ohne Schwierigkeiten auf- und abwickeln zu können ist vorgesehen, dass an der Seite (10) der Verpackungsfolie (1) mit der zumindest einen Schwächungslinie (8) im Bereich neben der Schwächungslinie (8) und zu beiden Seiten der Schwächungslinie (8) zumindest teilweise ein Stützlack (11) aufgetragen ist, um den durch die Aufwölbungen (9) entstehenden Dickenunterschied zumindest teilweise auszugleichen.
