Description

[Detailed Description of the Invention] The present invention relates to a label that uses release paper and has C.L. printability.

The back side of the label base material usually needs to be equipped with a printing device, so it cannot be peeled off like other adhesive products such as adhesive tape, so it is not possible to apply a peeling process to the back side of the label base material. When stacking multiple sheets of standard size material, a release paper is interposed between the adhesive layer of the upper layer of the label base material and the back surface of the lower layer of the label base material. .

However, the silicone normally used for the release paper is expensive and must be discarded when the label is used, resulting in an extremely uneconomical problem.

Furthermore, when the roll body is easily attached to a label printing machine and is rolled up in a large size, the diameter of the winding becomes large, which not only causes inconvenience in handling, but also the number of rolls is small compared to the roll diameter, which makes it difficult to install on the label printing machine. The disadvantage was that the roll body had to be attached more frequently, making label printing less efficient.

The present invention was devised to eliminate the drawbacks of conventional products such as sloping and to provide an economical label that eliminates the need for release paper. The label is characterized in that a pressure-sensitive adhesive layer is provided on the surface, and the back surface can be subjected to a peeling treatment to the extent that printing properties are not lost.

Next, one embodiment of the present invention will be described in detail with reference to the drawings.

In Figures 1 and 2, 1 is made of high-quality paper, and 2 is a fiber forming the base material 1, and the surface of the fiber is made of an octadecyl incyanate adduct of polyethyleneimine. After being coated with release agent 3 and subjected to release treatment (
・Ru.

4 is a rubber-based pressure-sensitive adhesive layer coated on the surface of the base material 1, 5 is printing ink that has entered the gap formed around the two fibers of the base material 1, and 6 is a feed notch in the label printing machine. L is made to pass through from the back surface of the base material 1 to the surface of the pressure sensitive adhesive layer 4.

In Fig. 1, 7 is a paper tube.

In the present invention, the base material may be paper such as high-quality paper, kraft paper, crepe processed paper, coated paper, or any type of fibrous material with printability such as various woven fabrics and non-woven fabrics. You can use any one.

Printability here refers to the performance of printing and writing that is applied to the surface of the label for the purpose of displaying a rondo number, etc., and is the performance of printing and writing when printed with water-based stamp ink or non-drying oil-based ink. It has a low temperature and does not easily desorb even after friction.

In addition to the commonly used silicone-based release agent, the release agent for the back surface 4 peeling process in the present invention may be a silicone-based release agent that is cheaper and has inferior peeling performance than the silicone-based release agent. Non-silicon release agents such as polymers having a chain alkyl group in their side chains are also suitably used.

The method of using such a release agent to release the back surface of the substrate to a degree that does not cause loss of printability is to apply a pressure-sensitive adhesive layer on the surface of the substrate in advance, and then apply a pressure-sensitive adhesive layer on the surface of the substrate. It is preferable to apply a release agent solution thinly to the convex portions of the rough surface using a roll coater method, transfer method, etc. and dry it. However, when the fibers are immersed in a release treatment solution prior to weaving, dried and subjected to release treatment, and the fibers are then woven, there are voids between the fibers. However, there is no loss of printability (・.

In the label of the present invention, the base material is made of a fibrous material, and the back side of the base material is subjected to a release treatment to a degree that does not lose printability, so there is no need for any release paper, and in particular, the label Because it is attached to the printing machine, when the roll body is closed, the number of ends becomes long compared to the diameter of the roll, and the frequency of attaching the roll body to the length label printing machine becomes less frequent, which improves the work efficiency of label printing. Improves efficiency.

In addition, the back surface of the base material has been subjected to a peeling treatment, and since the base material itself is formed from a fibrous material, it maintains a rough surface, and the rough surface is ?Since it has peeling performance, it is possible to use a non-silicon type peeling agent, which has not been widely used due to its inferior peeling performance, and it is possible to reduce the cost of peeling treatment.
