autobag the container strip 10 is formed by a first overlying ply or web or portion 12 and a second underlying ply or web portion 14 the webs 12 14 are joined together along their sides 16 18 so that a tube like structure is created in order to form the individual containers 11 as part of the strip a plurality of spaced heat sealed portions 20 are formed along the strip at regular intervals the seals 20 extend transversely of the strip and completely across the strip to include the sides 16 18 in order to complete the containers perforated lines 22 24 extend completely across webs 12 14 respectively and provide a line of weakness in the container strip for separation of the containers each container 11 contains a sheet like insert 26 the insert 26 is adhered to the web 14 along that portion of the insert disposed closest to the perforated lines 22 24 by a drop of hot melt glue 28 in this manner the insert forms a part of an inner surface of a product containing volume of the container accordingly when the container eventually is inflated by an airblast or otherwise the insert 26 will be held closely to the web portion 14 and the insert will not interfere with any product being loaded into the container also and perhaps more fundamentally the insert cannot be blown out of the container by the airblast that inflates the container inserts having different properties already are known and reference is made to the anti corrosion patents and to the co pending application referred to above for more information.
