Description

Surface sheet

Technical Field

The present invention relates to a sheet for adhering to objects such as packaging bags, in particular recyclable packaging bags.

Background

A sheet for packaging is known. After the advertisement or some logistics information is printed or written on the surface of the dough sheet, the dough sheet is pasted on the packaging bag and transported together with the packaging bag. In the transportation process, logistics information or advertisements carried by the bill are seen by logistics personnel or consumers, so that the information is transmitted. With the development of the logistics industry, various requirements are also put on the bill and the packaging bag, such as difficult breakage, easy sticking and printing operation, and guarantee of the safety of the contents. For the protection of the contents, the known packaging bags are made as so-called disposable packaging bags, i.e. once the contents are placed in the packaging bag and sealed, the packaging bag cannot be opened without destruction. However, such disposable packaging bags are very environmentally unfriendly, and particularly with the development of electronic commerce, the express delivery industry generates a large number of waste packaging bags every day.

In order to solve this problem, there are many recyclable packaging bags on the market, and after the receiver takes out the contents, the packaging bags are returned to the logistics company for recycling. For the circulating packaging bag, the situation that the packaging bag is prevented from being privately disassembled by others in the transportation process needs to be realized by a bill.

SUMMERY OF THE UTILITY MODEL

Based on the above problem, the present invention is directed to a sheet for sticking to an object such as a packing bag, which can ensure that the packing bag is not opened without authorization on the premise of realizing the function of displaying information of a conventional sheet for sticking to the object, or can prompt a user that the packing bag has been opened after being opened without authorization at least.

According to the utility model discloses a bill of surface, it is used for pasting on the target object, the bill of surface has bond line and bottom from type paper, the orientation of bond line the bottom is glued from one side coating of type paper, the adhesive property of gluing makes the bill of surface is pasted back on the target object, the bill of surface can not torn losslessly.

In particular, the tackiness of the glue is such that, immediately after the sheet has been affixed to the target object, the sheet is not able to be torn off without damage.

In particular, the adhesive layer is made of paper.

In particular, the adhesive layer is made of a film which cannot be torn off the packaging bag and can only be cut when the packaging bag is opened.

In particular, the side of the adhesive layer facing away from the underlying release paper is formed to display text, symbols, and graphic information.

In particular, the surface sheet also has an upper layer capable of displaying text, symbols, graphic information, and the side of the adhesive layer opposite to the bottom release paper is coated with a release agent for bonding the upper layer and the adhesive layer together in a form that can be separated without damage.

In particular, when the adhesive layer is torn off from the target object, the paper undergoes interlayer separation.

In particular, when the adhesive layer is torn off from the target object, a part of the glue remains on the target object.

In particular, the sheet cannot be torn off after it is affixed to the target object.

In particular, the target object is a recyclable packaging bag.

The sheet according to the present invention cannot be torn without damage after being stuck to a target object such as a packing bag. This ensures that the bag is not opened without authorization or can indicate to the user that the bag has been opened without authorization.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description. It should be noted that the figures only schematically show a sheet according to the invention, which does not show the sheet exactly in terms of dimensions. The embodiments shown in the figures are not intended to be restrictive of the invention, and any manner of conforming to the basic idea of the invention is to be considered as the subject of the invention.

Fig. 1 shows a cross-sectional view of a first embodiment of a bill according to the invention. The sheet has an adhesive layer 1 (which is used for adhesion to a target object when the sheet is attached to the target object such as a packaging bag) and a bottom release paper 2, wherein a side of the adhesive layer 1 facing the bottom release paper 2 is coated with an adhesive layer 11, and the adhesive property of the adhesive layer 11 is such that the sheet cannot be torn off without damage after being attached to the target object such as a packaging bag. In this case, in particular, immediately after the sheet has been applied to the target object, it is achieved that the sheet and the target object cannot be torn off without damage. The inability to be torn loose means: 1) the packaging bag is marked when the facial sheet is torn off, and/or the facial sheet is damaged and is not complete; 2) once adhered to the package, the sheet cannot be torn off and the package can only be opened by breaking the adhesive layer 1 completely (e.g., by cutting) to break the adhesive layer. In this case, the mark left on the packaging bag is realized in particular in such a way that a part of the glue remains on the packaging bag, for example a pattern is shown on the packaging bag and on the surface of the glue layer 11, which indicates that the sheet has been torn off. The way in which the sheet itself is broken without being completely torn off is in particular achieved in that the paper from which the adhesive layer 1 is made undergoes ply separation.

By the various modes, after the dough sheet is pasted at the sealing position of the recyclable packaging bag, the packaging bag is guaranteed not to be opened without authorization through the dough sheet, or a user is prompted after the packaging bag is opened, and the packaging bag is opened once.

The side of the adhesive layer opposite to the bottom release paper is formed to display text, symbols and graphic information. The above information is applied to the side of the adhesive layer opposite to the underlying release paper, for example, by handwriting, printing, or the like, thereby being used to display logistics information.

Fig. 2 shows a cross-sectional view of a second embodiment of a bill according to the invention. The adhesive layer 1 and the primer release paper 2 of the sheet of the second embodiment are the same as those of the sheet of the first embodiment, and will not be described in detail. The second embodiment differs from the first embodiment in that the sheet also has an upper layer 3 capable of displaying text, symbols, graphical information, and that the side of the adhesive layer 1 facing away from the underlying release paper 2 is coated with a release agent layer 12 for bonding the upper layer 3 and the adhesive layer 1 together in a fashion that can be separated without damage. For this embodiment, the logistics information is handwritten or printed on the surface of the upper layer 3, and the side of the upper layer 3 not intended to display the logistics information is coated with glue, which glue may be of the same or different composition as the above-mentioned glue layer 11. Because the upper layer is pasted on the parting agent layer 12, a user can conveniently tear the upper layer 3 after receiving the recyclable packaging bag, thereby ensuring that personal information is not leaked. Then, the adhesive layer 1 is torn or cut off from the packaging bag by breaking, and the contents of the packaging bag are taken out.

The recyclable packaging bag fitted with a sheet according to the invention is made of polyurethane, for example. The sealing of the recyclable packaging bag is realized by a zipper, a snap fastener or a magic tape.
