Claims10
A protective bag comprising:
- two foil layers connected along two longitudinal parallel connection lines of the same length, which length is selected to be in the range of 160-400 mm, inclusive,
- wherein each bag at a first end has a transverse welding line, connecting the bag's two foil layers all the way between the bag's two longitudinal connection lines,
- wherein the transverse welding line has a length selected to be in the range of 140-300 mm, inclusive,
- wherein the two longitudinal parallel connection lines extend to a second end of the bag opposite the first end,
- wherein each bag at the second end has an opening to a pocket between the two foil layers,
- wherein the pocket extends from the transverse welding line to the opening and from the one longitudinal connection line to the second longitudinal connection line,
- wherein the opening is demarcated by the two foil layers and
- i) by discrete weldings, connecting the two foil layers at the second end, or
- ii) by two transverse welding lines, connecting the two foil layers and each originating from a respective one of the two longitudinal connection lines, or
- iii) by one transverse welding line, connecting the two foil layers and originating from one of the two longitudinal connection lines, and by the second one of the two longitudinal connection lines,
- wherein the width of the opening, where this is smallest, measured in the direction perpendicular to the longitudinal connection lines, is narrowed by said discrete weldings or by said transverse welding line or lines, and is selected to be in the range of 80-200 mm, inclusive, and
- wherein the thickness of each of the two foil layers is selected to be in the range of 3-30 micrometres.

A web consisting of two foil layers of a thermoplastic material, with transverse perforated lines, which between the two foil layers and in the longitudinal direction of the web define a number of successive units, each of which has a first end and a second end, and which are intended for being individualized by division of the web along the transverse perforated lines,
- wherein the two foil layers of each unit are connected along two longitudinal parallel connection lines with the same length, which length is selected to be in the range of 160-400 mm, inclusive,
- wherein each unit at the first end has a transverse welding line, connecting the unit's two foil layers all the way between the unit's two longitudinal connection lines, and
- wherein the second end of each unit is defined by one of said transverse perforations,
- wherein the transverse welding line has a length selected to be in the range of 140-300 mm, inclusive,
- wherein each unit at the second end has an opening to a pocket between the two foil layers,
- wherein the pocket extends from the transverse welding line to the opening and from the one longitudinal connection line to the second longitudinal connection line,
- wherein the opening is demarcated
- i) by discrete weldings, connecting the two layers or
- ii) by two transverse welding lines, connecting the two layers and each of which originates from a respective one of the two longitudinal connection lines, or
- iii) by one transverse welding line, connecting the two layers and originating from one of the two longitudinal connection lines, and by the second one of the two longitudinal connection lines,
- wherein the width of the opening, where this is smallest, measured in the direction perpendicular to the longitudinal connection lines, is narrowed by said discrete weldings or by said transverse welding line or lines, and is selected to be in the range of 80-200 mm, inclusive, and
- wherein the thickness of each of the two foil layers is selected to be in the range of 3-30 micrometres.
