Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to an easily attachable plastic packaging bag for storing and storing office documents, drawings, photographs and the like.

(B) Conventional technology Envelopes and packaging bags using a thermoplastic film are mainly used, but when these are sandwiched between files or the like for storage or transportation, bags or contents It often slipped and was lost.

Further, when these are directly attached to a wall, a blackboard or the like, it is extremely complicated to attach them separately with an adhesive tape (eg, cellophane tape under the trade name). As shown in FIG. 2, there was a method of using an adhesive tape on the opening portion, but the adhesive tape was not preliminarily provided on the envelope in order to fix the envelope itself to a wall or the like. In FIG. 2, A indicates an envelope main body portion, B indicates an envelope lid portion, and C indicates a sealing tape.

Further, even when the contents of these packaging bags are classified and displayed, it is difficult for the conventional plastic film to be written or stamped with a water-based ink and easily erased, which is not practical.

(D) Problems to be solved by the invention In particular, when the packaging bag is sandwiched and stored in a file or the like, in order to prevent the contents contained in the document from slipping down, the conventional so-called folding is used. It is possible to make the lid (or seam allowance) larger or to attach a tab etc. to the lid side and the main body side so that it can be opened freely, but such a structure causes high cost and opening and closing There is a problem that it takes time to operate.

Further, if the folding lid (or the glue allowance) is simply attached, the packaging bag will be used up only once, which is uneconomical.

In view of the problems of the prior art, the present invention can be easily attached to various files or the like, or can be fixed on a wall, a blackboard, a desk, etc., so that the contents do not easily slip off and the contents are prevented from being lost. The purpose is to give the packaging bag an advertising effect while being able to do it.

(E) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a plastic packaging bag in which a double-sided adhesive tape is attached to the back surface of one end opening of the plastic packaging bag. An opening having a surface film shorter than the back film is provided, and a lid-like portion slightly covering the opening by welding is provided from the upper end of the opening to the left and right, and the left and right portions are not welded. The means of providing a cover piece was taken.

Further, in carrying out the present invention, it is preferable to apply a highly water-absorptive printing ink capable of writing or stamping to the entire front surface or the back surface of the plastic packaging bag or a necessary portion.

(F) Action According to the present invention, in particular, the packaging bag has a lid-like portion that slightly covers the opening from the upper end to the left and right by welding.
And by providing a cover lid piece having a portion that does not weld the left and right, the lid-like portion that slightly covers the opening by welding from the upper end of the opening to the left and right, when the packaging bag is turned upside down, Together with the front and back films, the bottomed part is formed. That is, it forms a fixed and partial bottom portion that is different from a conventional folding lid. Therefore, the inside document is received by the bottom and does not slip off the bag.

Further, since the double-sided adhesive tape can fix the packaging bag itself to a wall, a file, etc., the packaging bag itself does not drop.

Furthermore, by applying the superabsorbent printing ink on the front surface or the back surface of the packaging bag, subsequent writing or stamping can be performed, and the benefit of its use is expanded.

(G) Examples Hereinafter, preferred examples of the easy-to-stick plastic packaging bag of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, one surface of the double-sided adhesive tape (4) is attached to the back surface of the opening of the plastic packaging bag (1) at one end, and the packaging bag is used, that is, the packaging bag in a file or a wall, a blackboard. When the tape is fixed to a sheet of paper or the like, the release paper (4-1) of the double-sided tape (4) is removed and attached to a necessary place.

In addition, for example, the main body portion (2) of the surface film (2) of the plastic packaging bag (1) is prevented so that the contents do not fall down due to falling up and down, such as when it is fixedly attached to a file and moved.
-1) is provided with an opening that is shorter than the back film (3), and has a lid-like portion (2-2) that slightly covers the opening by welding from the upper end of the opening to the left and right, and Cover lid piece (2-3) having left and right portions that are not welded
Is provided.

Further, on the front surface or the back surface of the packaging bag, in order to describe, for example, the manufacturer, manufacturing date, seller, quality indication, reference number, etc. of the contents, it is possible to print with water-based ink, etc. Printing (6) can be performed using an ink, for example, an ink using a superabsorbent polymer described in Japanese Patent Application No. 62-159040 filed by the present inventors.

If the contents need to be observed from the outside, the packaging bag should be left as a transparent film, and only the display part should be the printed part with the ink. As shown in the figure, the entire printing surface is used.

(H) Effect of the Invention According to the present invention, it is possible to prevent the bags or contents arranged between files and ledgers from falling off or being lost during storage and movement, and also to use bulletin boards, blackboards, and walls. It can be performed very easily even when it is attached to etc.

In addition, when a printing band made of a predetermined ink is provided, writing and stamping can be performed, and not only the required display can be performed but also an advertising effect can be provided.
