Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing composite sheets such as stickers and stickers, and when providing an adhesive layer on one side of a front base material, which is a printed sheet, regardless of the material of the front base material. , the adhesive layer can be fixed evenly on the surface of the front substrate without being absorbed by the front substrate, and the step of preventing absorption of the adhesive can be omitted in the manufacturing process of composite sheets such as stickers and stickers, and the manufacturing process The purpose is to reduce the

Currently, in order to apply an adhesive to a printing substrate printed on both sides or one side of composite sheets such as stickers and stickers, depending on the material of the printing substrate, i.e., paper, non-woven fabric, etc. Because the adhesive is absorbed into the material and the adhesive is not completely applied,
After applying the adhesive absorption prevention layer to the adhesive-coated surface of the printing substrate, the adhesive layer of the separator mount, whose release-treated surface is coated with adhesive, is aligned with the absorption prevention layer, and printing is performed. An adhesive layer was formed on the base material. However, after going through this process,
One step is required to construct the anti-absorption layer,
It is not possible to immediately apply an adhesive layer to a printed substrate that has been printed.

The present invention improves this point, and an embodiment thereof will be described below with reference to the drawings.

Reference numeral 1 denotes a printed base material made of paper, nonwoven fabric, and other appropriate materials, and a printed layer 2 is provided on one or both sides of the printed base material 3 to form a front base material 3. Reference numeral 4 denotes a separator mount, one side of which has a so-called release surface 5 coated with, for example, silicone to make it easier to peel off, an adhesive layer 6 is provided on the release surface 5, and paper, PVC, polypropylene, etc. The separator 8 constitutes a sheet-like layer 7 such as
It is as follows. The separator 8 may be a long roll or a sheet.

The front base material 3 that has been printed above and the separator 8
Composite sheet 1 for stickers, stickers, etc. by gluing
However, for convenience of printing, the front base material 3 is made of sheets. And the above separator 8 prepared separately
The sheet layer 7 and the appropriate printing layer 2 of the front base material 3 are combined and adhered using adhesive 9, and the separator mount 4 is cut to match the front base material 3, and composite sheets such as sheet stickers, stickers, etc. Let it be sheet 10.

When the front base material 3 is double-sided printed, the printed surface must be viewed from both sides of the front base material. For this purpose, the separator sheet layer 7 must be transparent. In other cases, the sheet layer 7 may be transparent or opaque.

When using a composite sheet such as a sticker or sticker, only the separator mount 4 is peeled off, and the adhesive 6 remains on the front base material 3 side, allowing it to be pasted at an appropriate location.

According to the method of the present invention, the front base material 3 and the separator 8
It is made by a completely different process. If the front base material 3 is printed at an appropriate printing factory and brought to a factory for manufacturing composite sheets such as stickers and stickers, the separator 8 is appropriately pasted on the front base material 3 using an adhesive at the factory. Base material 3 and separator 8
can be integrated into a composite sheet for stickers, stickers, etc.

Since the method of the present invention is as described above, if the printed front base material is brought to the factory, composite sheets such as stickers and stickers can be manufactured by simply pasting the front base material separator mount at the factory. This is advantageous in terms of work since the process of separately forming an anti-absorption layer on the printing surface can be omitted.

In addition, since the adhesive 6 of the separator 8 exists in a sandwiched state between the separator mount 4 and the sheet layer 7 such as PVC, when the separator 8 is attached to the front base material 3, the separator Depending on the material of the printing base material 3, the adhesive 6 on the mount 4 is absorbed by the printing base material 1 of the front base material 3,
It is possible to prevent a situation that would cause a difference in adhesive strength from occurring.

In addition, the adhesive type can be arbitrarily selected by appropriately selecting an adhesive such as a temporary adhesive type or a permanent adhesive type depending on the adhesive type.
