Abstract
A flexible, single-material pouch, sealed for containment of a liquid or solid product, has a front wall and a rear wall welded together, and a left lead-in and a right lead-in joined by an imaginary tear line. The front wall and the rear wall are constituted of a flexible multilayer film constituted of an inner sealing layer and an outer layer made of mono-oriented polypropylene (MDOPP) parallel to the imaginary tear line.

A flexible, single-material pouch, sealed for containment of a liquid or solid product, the flexible, single-material pouch comprising a front wall having a left side, an upper side and a right side, and a rear wall having a left side, an upper side and a right side, wherein
- the left side of the front wall is welded to the left side of the rear wall to form a left edge of the flexible, single-material pouch, the upper side of the front wall is welded to the upper side of the rear wall to form an upper edge of the flexible, single-material pouch, and the right side of the front wall is welded to the right side of the rear wall to form a right edge of the flexible, single-material pouch;
- the flexible, single-material pouch further comprises a left lead-in along the left edge, near the upper edge and a right lead-in along the right edge, near the upper edge, the left and right lead-ins being joined by an imaginary tear line;
- and
- the front wall and the rear wall are constituted of a laminated flexible multilayer film constituted of an inner sealing layer and an outer layer, wherein the inner sealing layer faces an inside of the flexible, single-material pouch and comprises a sealing surface sub-layer made of polypropylene (PP), and wherein the outer layer is made of mono-oriented polypropylene (MDOPP) parallel to the imaginary tear line.
A reel comprising a reel body and a laminated flexible multilayer film wound around the reel body, wherein the laminated flexible multilayer film is constituted of an inner sealing layer and an outer layer, wherein the inner sealing layer comprises a sealing surface sub-layer made of polypropylene (PP), wherein the laminated flexible multilayer film is unwound from the reel body along an unwinding direction, and wherein the outer layer is made of mono-oriented polypropylene (MDOPP) parallel to the unwinding direction.
A flexible, single-material pouch, sealed for containment of a liquid or solid product, the flexible, single-material pouch comprising a front wall having a left side, an upper side and a right side, and a rear wall having a left side, an upper side and a right side, wherein
- the left side of the front wall is welded to the left side of the rear wall to form a left edge of the flexible, single-material pouch, the upper side of the front wall is welded to the upper side of the rear wall to form an upper edge of the flexible, single-material pouch, and the right side of the front wall is welded to the right side of the rear wall to form a right edge of the flexible, single-material pouch;
- the flexible, single-material pouch further comprises a left lead-in along the left edge, near the upper edge and a right lead-in along the right edge, near the upper edge, the left and right lead-ins being joined by an imaginary tear line;
- and
- the front wall and the rear wall are made of a laminated flexible multilayer film constituted of an inner sealing layer, an outer layer, and an intermediate layer arranged between the inner sealing layer and the outer layer and having gas barrier properties, wherein the inner sealing layer faces an inside of the flexible, single-material pouch and is made of polypropylene (PP), and wherein the outer layer is made of mono-oriented polypropylene (MDOPP) parallel to the imaginary tear line.
A reel comprising a reel body and a laminated flexible multilayer film wound around the reel body, wherein the laminated flexible multilayer film is constituted of an inner sealing layer, an outer layer, and an intermediate layer arranged between the inner sealing layer and the outer layer, wherein the inner sealing layer is made of polypropylene (PP) and the intermediate layer has gas barrier properties, wherein the laminated flexible multilayer film is unwound from the reel body along an unwinding direction, and wherein the outer layer is made of mono-oriented polypropylene (MDOPP) parallel to the unwinding direction.
