Title (EN) PACKING AND MANUFACTURING PROCESS THEREOF
(FR) EMBALLAGE ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)The packing comprises an envelope provided with a tearing tongue (7) and comprised of a flexible and foldable material. This envelope comprises a double thickness section, wherein the two layers (4, 5) are bound one against the other and where the free end of the tearing tongue is located. Both layers and the tongue may be secured together in a gas tight relationship. To facilitate the tearing of the tongue (7), a zone of the layer (5) of the envelope which is opposite to the layer (4) at the location where it is provided with the tongue (7) is delimited by weakening lines (12) so as to be easily detached from the rest of the envelope during the tearing of the tongue. For manufacturing bags, the tearing tongue (7) is arranged preferably along the length of the band of packing material. A support layer having weakening lines provided by cutting is joined with a tight, non-perforated layer of packing material.
