Description

Technical Field

[0001] The utility model belongs to the technical field of packaging materials, and in particular relates to a single-bottom paper double-sided adhesive bonding structure with a tear handle. Background Art

[0002] Double-sided adhesive tape is one of the commonly used materials for bonding between materials. It has been widely used in the fields of thermal insulation pads, new energy batteries, electronic products, etc. At present, the double-sided adhesive tape with tearing fingers is composed of at least three layers of materials, including a bottom paper layer with tearing fingers, a double-sided adhesive layer and a bottom paper layer with a load-bearing function. Before using the double-sided adhesive tape with a tearing finger bottom paper layer, the load-bearing bottom paper layer needs to be removed first, and then the surface of the product is bonded. After bonding, the bottom paper layer containing the tearing finger is removed before the bonded product is bonded with other products. The three-layer double-sided adhesive tape structure with tearing fingers uses at least two layers of bottom paper, and the bottom paper will be removed before the products are bonded. The amount of low-quality paper used is large, causing a lot of pollution and high material cost. In addition, the production and processing process of the three-layer double-sided adhesive tape structure with tearing fingers requires that the double-sided adhesive tape containing the tearing finger bottom paper be bonded to the carrier film bottom paper after the double-sided adhesive is die-cut. At the same time, the production and use process of the three-layer double-sided adhesive tape structure with tearing fingers requires that the carrier film be torn off and removed first, and then the double-sided adhesive tape containing the tearing finger bottom paper is bonded to the product. Utility Model Content

[0003] In view of the deficiencies described in the above-mentioned prior art, the utility model provides a single-base paper double-sided adhesive bonding structure with a tear handle. The bonding process does not require an additional layer of low-bearing paper for support, which reduces the use of base paper, reduces waste, and is more environmentally friendly.

[0004] The technical solution adopted by the utility model is:

[0005] A single-base paper double-sided adhesive bonding structure with a tearing handle, comprising a single-base paper with a tearing handle and double-sided adhesive, wherein the single-base paper with a tearing handle comprises a tearable base paper portion and a base paper use portion, wherein the tearable base paper portion is provided with at least one use portion position area; each use portion position area is provided with a base paper use portion, and the outer edge of the base paper use portion and the inner edge of the use portion position area form a seam I; the tearable base paper portion is separated from the base paper use portion by the seam I; and the base paper use portion is provided with a protruding tearing handle;

[0006] The double-sided adhesive structure comprises a tearable tool edge portion and a double-sided adhesive bonding portion, the tearable tool edge portion is provided with at least one bonding portion position area; each bonding portion position area is provided with a double-sided adhesive bonding portion, and the outer edge of the double-sided adhesive bonding portion and the inner edge of the bonding portion position area form a seam II; the tearable tool edge portion is separated from the base paper use portion through the seam II;

[0007] The double-sided tape bonding part is pressed against the backing paper usage part and the maximum bonding coverage of each double-sided tape bonding part on the corresponding backing paper usage part is that the boundary of the joint II and the joint I coincides and only the protruding tear hand part exceeds the double-sided tape bonding part.

[0008] The tearable backing paper portion and the tearable tool edge portion can be removed after lamination, so that a plurality of lamination structures can be formed at one time, and only one backing paper is used without the aid of a carrier film, thereby reducing the use of the backing paper.

[0009] The final shape can be stored in rolls or sheets when not in use, and the layout can be one row or multiple rows.

[0010] As a preferred embodiment of the present invention, the seam I is a fully disconnected seam, an easy-tear seam or a point-connected seam. The easy-tear seam can be a semi-transparent seam, a point-line seam, a short line seam or a point-type seam. The semi-transparent easy-tear seam is a seam that does not cut through the thickness direction, forming an easy-tear mark. The point-connected seam is connected at points, and adjacent points are disconnected.

[0011] As a preferred solution of the utility model, the seam I on the same single base paper with tear handles is at least one structure.

[0012] As a preferred solution of the utility model, the seam II is a fully disconnected seam, an easily tearable seam or a point-connected seam.

[0013] As a preferred solution of the utility model, the joint II on the same double-sided adhesive tape is at least one structure.

[0014] As a preferred solution of the utility model, the tearable backing paper portion and / or the tearable tool edge portion are provided with an easy-tear seam, which is convenient for removing the tearable backing paper portion or the tearable tool edge portion.

[0015] The utility model uses a single tearable base paper and a tearable double-sided adhesive tape for bonding. When in use, the base paper can be removed with the help of a raised tear handle and can be quickly bonded to the product. The bonding process does not require an additional layer of low-bearing paper for bearing, thereby reducing the amount of base paper used, reducing waste and being more environmentally friendly.

[0016] The utility model has only two layers of materials and the bottom paper layer has a tearing handle, which effectively reduces the amount of bottom paper used, and at the same time saves the process of laminating the release paper of the carrier layer and the process of removing the bottom paper of the carrier layer, thereby improving the processing efficiency. The structure adopts an innovative seam design, which realizes the continuous layout of multiple pieces of the double-sided adhesive laminating structure of the double-layer single bottom paper with a tearing handle in one row or multiple rows, and realizes the removal of the double-sided adhesive tool edge part after laminating without affecting the single bottom paper with a tearing handle.
