Folder made of plastic film, closed on both sides

The invention relates to a double-ended ^A ktenhülle of plastic film, consisting of Onea base sheet and a 'it therefrom to Ernest transverse edge and a! »Ängsrand associated cover sheet and at least a sur between the base and cover forming a plurality of compartments provided insert sheet. ,,

There is a known folder of this type (BBP 1 026 281) from a plastic strip the length of one of the sheaths corresponding Breito and about * one of the three times the envelope width corresponding length »which strips on the simple envelope is folded to susaiomen, with the base sheet and the cover sheet of the envelope on a transverse to the folds running tape are welded together. The rear compartment of this cover is thus a three-sided ß-

Furthermore, it is difficult to find the insert sheet which corresponds in size to the base sheet and the cover sheet '' in the correct position between the base and cover sheet to be arranged because the base and cover sheets are connected to one another at the lower transverse edge by an edge weld seam «

The object of the invention eats a bilaterally closed Form file cover made of plastic film with several compartments so that the cover can be handled and usability with simple smocks improved will"

To achieve this object, the invention provides that the insert sheet is provided on a band with a folded strip forming a bow and is connected to one of the cover sheets by means of this fold strip by a weld or adhesive seam at a distance from the bow. _R is impaired, so that a shell is selche brawhbar for many ^purposes: by this measure that all subjects "* are equally accessible from the outside and maintain capacity * is achieved.

A particularly favorable embodiment of the casing also with regard to the capacity results when the base and cover sheets are made from one piece of film in a known manner are, by the film suz »Creation of the longitudinal bus

The handling of the Küllo can be further improved as a result be that the insert sheet and the base sheet in a known manner with each. one handle recess are provided, which recesses are staggered are.

Around the most precipitated part of the envelope, namely the right lower corner, to be able to protect from tearing the cathedral all handle recesses at a distance from the lower transverse bend the shell ends.

Furthermore, to improve the usability of the cover, the base and cover sheet made of soft film and the insert sheet can be used be made of rigid foil. On the one hand, this measure improves the stability of the casing and yet dureh the hard foil sheet from breaking points Keeps kinking.

In the drawing, an embodiment of the ER is * shown findungsgegenatandes. 1 shows the cover in a pictorial representation and FIG. 2 shows a view of the cover from above.

In the example shown, all handle recesses end at a certain distance from the lower transverse bend 12 of the cover, the recess running back into a rounded edge 13 ζ \ χύ free account of the respective cover sheet. In this way, the most stressed point in the case of envelopes closed on both sides, namely the lower right corner 14 ·, is spared by being spared excessive tensile stress during the opening of the envelope compartments.

On the other hand, the sheets, in particular the cover sheet, in the case of file covers made of hard foil, tend to break relatively soon at individual cleats. Rigid foils are very sensitive to kinking and chafing. As soon as a local excessive stress of this kind has arisen at a point, there is aogenaa & te whitening, ie discoloration of the foil, which is transparent 6 made of rigid foil, on the other hand the outer ones.
