Abstract

Bag blank (13) comprising an inflatable package blank (11) on a running web, which package blank (11) comprises a semi-finished product consisting of a first plane plastic sheeting (21) and a second plane plastic sheeting (22), which plastic sheetings abut with their plane surfaces against each other and are interconnected by welds (18) so that a series of delimited transverse chambers (16) is formed between the two plastic sheetings (21,22) across the surface of the entire package blank (11), this semi-finished product being folded or welded together along a longitudinal centre line (14) so that its two long sides are parallel and face in the same direction, and that a first longitudinal suspension arrangement (15, 23a, 43a) is connected to the edge along the first long side of the package blank (11) or the bag blank (13), and that a second longitudinal suspension arrangement (23b, 43b) is applied at the edge along the second long side of the package blank (11) or the bag blank (13), as well that the bag blank (13) is provided with transverse full-penetration weldings (18) having a length that has been terminated a distance from the longitudinal suspension arrangements.

Description

TECHNICAL FIELD[0001]The present invention relates to a bag blank, which is formed of an inflatable package blank and a method and a device to pack products using such a bag blank. These package blanks are formed with a plurality of channels, which can be gas-filled and closed to obtain a shock-absorbing gas cushion, preferably air cushion, around the packed product or products.BACKGROUND OF THE INVENTION[0002]The background of the invention is seen in the published patent application US 201010251665, which shows a machine for the inflation and sealing of an inflatable structure. Said structure is provided with double layers of a plastic film, which layers are welded in such a way that the structure forms transverse bubble-like channels, which can be gas-filled and welded together longitudinally to obtain a shock-absorbing gas-filled package structure consisting of a plurality of gas occlusions oriented in the cross-direction of the structure. The mentioned patent application shows,...
