A carrier-bag for plate-shaped articles which a rectangular containing part made of a film folded in a W shape and having a structure in which each pair of an outer film and an inner film of the W-shaped film is separately heat sealed together at both side edges of the containing part, and a pair of holding parts formed by upward extension of the outer films of the W-shaped film and having finger holes; and a process for producing the carrier-bag which comprises forming a belt-shaped film having W-shaped gazette foldings at both side edges from a long tubular plastic film, inserting a heat insulating receiving plate into the central part of each W-shaped gazette folding of the belt-shaped film and pushing heat sealing blades to the receiving plate from both sides to separately heat seal each pair of an outer film and an inner film of the W-shaped film together, cutting the belt-shaped film to produce pieces having a length corresponding to the width of a carrier-bag, cutting the obtained pieces along the center line in the longitudinal direction, and punching finger holes in the holding parts.
The carrier-bag for plate-shaped articles made of a plastic film has a simple structure, is easily handled, can be produced economically in accordance with a simple process, and contains plate-shaped articles horizontally.
