Package capable of being sealed by heat-fusing

A packaging pouch (1) having a laminate (4) of easily peelable tapes secured by heat-bonding to laminates (5) of the package body where an opening of the package is to be formed. The former laminate (4) has outer heat-bonding layers (41,42) heat-fusible to the heat-sealing layers (52) of the latter...

Beschreibung
Zusammenfassung:	A packaging pouch (1) having a laminate (4) of easily peelable tapes secured by heat-bonding to laminates (5) of the package body where an opening of the package is to be formed. The former laminate (4) has outer heat-bonding layers (41,42) heat-fusible to the heat-sealing layers (52) of the latter laminates (5). The bond strength between the heat-bonding layers (41,42) are adjusted such that they can be peeled from each other by hand. The former laminate (4) may be formed by co-extruding synthetic resins or by heat-bonding. The laminate (4) may protrude farther into the package body than the heat-sealed portion (B) of the package body.
