BRIEF SUMMARY
BACKGROUND OF THE INVENTION
When foodstuffs are packaged in tubular packaging sheaths which consist of plastic, natural intestine or netting and are closed by closing clips applied by closing machines, it is often desired to insert into the closing clip a tag which is provided with the inscription required on the packaging sheath. In some countries there are even regulations prescribing such tags to be provided with a large amount of information concerning the contents, weight, price per unit, total price and expiration date. The required information should easily be legible and clearly arranged on the tag and the tag must permit the inscription to be applied, mostly printed, before or after the sheath is closed, e.g., in automatic weighing plants. For this reason a sufficient size, particularly a sufficient width, is required. Besides, such tags must have a portion which can readily be received by the closing clip and can be gripped as the packaging sheath is closed.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a tag strip which serves to insert individual tags into respective closing clips for tubular packaging sheaths before the latter are closed and which comprises tags which meet the requirements set forth hereinbefore.

DETAILED DESCRIPTION OF THE INVENTION
In a tag strip according to the prior art part of the main claim that object is accomplished in that the tag strip is provided with a continuous perforation line in the feeding direction so that the strip can be fed in a tag applying machine and that the perforation line extends also in the narrower fixing portion.
Whereas a large number of tag strips for an adhering of individual tags are known, inclusive of tag strips having a narrower portion (FR-A-2 248 762), such tag strips do not have a continuous perforation line for the feeding of the strips. Other tag strips, which have a perforation line for use in a tag-applying machine (DE-A-2109665) do not have a continuous perforation line for use in feeding the strip. Tags which are perforated for being fed are not provided with a special portion which can be inserted into a closing clip for tubular packaging sheaths. Whereas so-called code lugs for insertion into closing clips are known, they are relatively narrow and for this reason cannot be provided with the above-mentioned information which is desired and they are so narrow that they cannot be provided with perforations, particularly because such perforations would further reduce the areas which are available for inscriptions.
In the tag strip in accordance with the invention the continuous perforation line may be provided approximately at the center of the width of the strip so that the free area which is provided on the tag for receiving inscriptions will be approximately symmetrically arranged on both sides of the continuous perforation line. Such tags are particularly suitable for being printed before the packaging sleeves are closed.
But if printing is to be performed after the closing operation because the weight of each filled package, e.g., of a turkey, is to be stated on the tag, a wide tag which is provided with a continuous perforation line approximately at the center of its width will not always be desirable or required, particularly if the tag is printed as it is pulled through. In that case it will be desirable to provide the free area that is to be printed only on one side of the continuous perforation line because this will facilitate the handling and will save material.
The tag strip in accordance with the invention may be made of paper or of a printable plastic. If the strip consists of a relatively thin paper, which is suitable for the intend
