Film bag

Abstract

A film bag having a bag body is formed with two front walls. A first lateral edge, which is formed by at least the two front walls, is connected at a first corner of the bag body to an upper bag edge. At the upper bag edge, the two front walls are interconnected by a fastening seam. Each of the front walls has, at the first corner, multiple lines of weakness that extend, in a curve and spaced from each other, from the first lateral edge up to the fastening seam. A tear-open aid is situated on the fastening seam. At least three lines of weakness are provided. The tear-open aid is designed and situated in such a way that the aid allows for a tearing-open, at the upper bag edge, between any two adjacent lines of weakness.

Description

CROSS-REFERENCE TO A RELATED APPLICATION[0001]The invention described and claimed hereinbelow is also described in German Priority Document DE 10 2016 100 824.9, filed on Jan. 19, 2016. The German Priority Document, the subject matter of which is incorporated herein by reference, provides the basis for a claim of priority of invention under 35 U.S.C. 119(a)-(d).BACKGROUND OF THE INVENTION[0002]The invention relates to a film bag having a bag body comprising two front walls, wherein a first lateral edge, which is formed from at least the two front walls, is connected at a first corner of the bag body to an upper bag edge, at which the two front walls are interconnected by a fastening seam. Each of the front walls comprises, at the first corner, multiple lines of weakness which extend, in a curve and spaced from each other, from the first lateral edge up to the fastening seam. A tear-open aid is situated on the fastening seam.[0003]Film bags are opened in highly diverse ways in practi...

AI Technical Summary

Benefits of technology

The present invention is a film bag that can be torn open easily and flexibly. This solves the problem of difficulty and flexibility in known art.

Problems solved by technology

Such a separation can take place either by the seal being opened or by a material failure within the layered composite, wherein either an adhesive failure or a co-adhesive failure results.

Further tearing-open by a user, however, is difficult to control, even when oriented film layers made from oriented polyethylene terephthalate (OPET) or biaxially oriented polypropylene (BO-PP) allow for easy tearing.

To select the different tear-open options, a high-level of attentiveness on the part of the user is necessary, wherein incorrect handling cannot be ruled out with certainty.

The manufacturing of the bag is complicated, however, because large areas must be sealed to achieve the described functionality.

In this case as well, incorrect handling can result in the film bag being inadvertently completely opened.

The risk of an uncontrolled tearing-open exists precisely at such angulations.
