Storage bag

A method of making a storage bag (10) comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends (14a, 14b), and a diameter; (b) flattening the tube in...

Zusammenfassung:	A method of making a storage bag (10) comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends (14a, 14b), and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint (15) at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet (20) having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet (20) over the joint (15) such that the first side comprising a lower melting polymer engages the joint (15) and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag (10) made by such method.
