Description

Description: TECHNICAL FIELD The present invention relates to a postal matter having a peelable adhesive paper surface and a method for manufacturing the same, and in particular, can improve the appearance of a printing / printing surface when the paper surface is peeled off. The present invention relates to a mail and a method of manufacturing the same.

(Prior Art) Various types of so-called secret postcards have been proposed as postcards for direct mail and various notifications. One example is to fold a sheet twice the size of a normal postcard into two, or to stack two normal postcards and glue them together with a peelable adhesive seal between them, or use a heat-sensitive adhesive in advance. Using paper that has been squeezed into it, fold the paper twice as large as a normal postcard into two pieces, and glue them releasably with a hot roll, etc. to secure the printing / printing area and protect privacy. There is something that I did.

(Problems to be Solved by the Invention) On the other hand, the inventor of the present invention folded a postcard body twice as large as a normal postcard into two, and applied a non-peelable first adhesive to the entire outer periphery of the back surface. While applying the peelable second adhesive to the inside and bonding the postcard body, a perforation is inserted inside the outer edge bonding portion, and one of the postcard bodies bonded in two from the perforation is peeled to remove the bonding surface. We have developed and applied for a postcard that has been exposed and that has solved the problems of automation and printing / printing restrictions (Japanese Utility Model Application No. 1-55165).
issue).

In addition, the present inventor folds an automatically printable unit sheet having a width three times as large as a normal postcard and having the same length as a normal postcard into three in the width direction to form the first, second, and third surfaces and A back surface is formed, and the first surface is used as a destination surface, and at least one of the second and third surfaces is used as a writing surface and can be printed together with the first surface by single-sided printing. An adhesive is applied to the second back surface so that the second front surface and the third back surface and the first back surface and the second back surface can be respectively releasably adhered to each other, thereby facilitating automatic printing. Developed and filed an application for the continuous paper (Japanese Utility Model Application No. 1-96606).

By the way, in the above-mentioned postcard, when printing and printing paper surfaces are bonded to each other, a method of printing and printing on the paper surface, applying an adhesive on the printing surface, and bonding the adhesive is considered.

However, in such a method, when the adhesive on the paper surface is peeled off, the printing paint layer and the printing ink layer adhere to the adhesive side and peel off from the paper surface, resulting in a problem that the appearance of printing and printing deteriorates.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a mail having a peelable adhesive paper surface capable of guaranteeing the appearance of a printing / printing surface when the adhesive paper surface is peeled off, and a method of manufacturing the same.

The inventor of the present invention has made intensive studies to solve the above-mentioned problems, and as a result, completed the present invention by focusing on the following points. That is, conventionally, in order to protect printing and printing on the paper surface, a resin coating agent is applied thereon after printing and printing, and when the resin coating agent is applied, this resin coating agent is applied. May function as a release layer, which may make it more difficult to adhere to the paper surface.

However, as a result of repeating various experiments on the bonding method by the present inventor, if the heat sealing temperature is set to a relatively low temperature range and the pressure is softly applied at a relatively low pressure during the heat sealing, the heat sealing bonding is performed. The agent oozes out onto the surface through the printing / printing layer and resin coating layer (release layer) and adheres well, and the adhesive strength between the printing / printing layer is moderate and the adhesive strength between the paper surface and the printing / printing layer The adhesive layer attracts the printing / printing layer to the paper surface, and in this case, the printing / printing layer is protected by the release layer, and it has been confirmed that the appearance of the printing / printing surface can be secured. Was.

(Means for Solving the Problems) Therefore, a mail having a peelable adhesive paper surface according to the present invention includes a printing paper, an adhesive layer printed and applied over the entire surface thereof, and a print on the adhesive layer. Except for the printing area surface and the resin coating layer applied to the printing area surface except for the four-sided peripheral part, when a pair of opposed printing papers are bonded by heating and pressing, the exposed part is exposed to the four-sided peripheral part of the paper. While the opposing adhesive layers strongly adhere to each other in a peelable manner, the lower adhesive leaches to the upper surface via the resin coating layer on the printing area surface, and the other resin coating surface is the printing area surface and the printing paper. It is weaker than the adhesive strength with the surface, and it is weakly adhered so that it can be peeled without removing the printing area surface. ''
The gist is that.

Further, the method for producing a mail having a peelable adhesive paper surface according to the present invention comprises the steps of: “printing and applying a heat-sealing adhesive on the first paper surface and the second paper surface, and printing the adhesive layer on the printed or printed paper surface. Forming a printed layer on the heat-sealing adhesive on the first paper surface or the second paper surface so that the adhesive leaches onto the upper surface of the printed layer surface, and forming the printed layer; A step of printing and applying a resin coating agent on the first paper surface and the second paper surface such that the lower adhesive is leached to the upper surface via the printing layer and the resin coating layer to form a release layer; The second paper surfaces are overlapped with each other, and are heated in a predetermined temperature range to strongly adhere the opposing adhesive layers exposed on the four sides of the paper so that the opposing adhesive layers can be peeled off from each other. Leach on the upper surface through the layer and the other side resin coating surface is the printing area And a step of weakly adhering the surface of the printing area without peeling off the printing area surface, which is weaker than the adhesive strength between the surface and the printing paper surface. "

The reason why printing and printing are performed after applying the heat seal adhesive is that if it is performed in reverse, the adhesion between the printing and printing layer and the paper surface cannot be secured, and the printing and printing layer is easily peeled from the paper surface Because it becomes.

Moreover, heat-sealing adhesive predetermined peel strength to be easily peeled off the adhesive paper manually, for example, something like what if heat seal adhesive peel strength of 15 mm ² is bonded with strength is 100~200g It may be.

The resin adhesive may be any as long as it protects the ink layer for printing and printing. For example, a Si resin-based resin coating agent can be used.

On the other hand, if the heat sealing temperature is too high, the paper surfaces are firmly adhered to each other and cannot be peeled off, whereas if it is too low, the effect of exuding the adhesive cannot be obtained. Since the actual temperature changes, it is necessary to determine the temperature in advance according to the paper feed speed and the pressing force.

In addition, the pressure during heat sealing is too large, and when it becomes hard, the adhesive enters the paper surface and the paper surfaces are firmly adhered to each other and cannot be peeled off, while it is too low and when it becomes too soft, the adhesive oozes out Although no effect can be obtained, since this also substantially varies depending on the paper feed speed, it is necessary to determine the effect in advance according to the paper feed speed.

(Function) In the present invention, a heat seal adhesive is printed and applied to a paper surface, and printing or printing is performed on the heat seal adhesive on the paper surface, and a resin coating agent is printed and applied while leaving the periphery thereon. Since the paper surfaces are overlapped with each other and heated to a relatively high temperature and softly pressed at a relatively low pressure, the heat seal adhesive on the peripheral edge of the paper surface peels off from each other when bonding. Adhesion is as strong as possible, and the heat seal adhesive oozes out to the surface through the printing / printing layer and release layer, and the printing / printing paper surface is adhered to each other, and a moderate adhesion lower than the paper surface and the printing / printing layer When peeling the paper surface, the heat seal adhesive pulls and fixes the printing / printing layer so that it does not separate to the paper side, and the peeling layer prevents the printing / printing ink layer from peeling off. Printing The appearance of the surface is ensured.

(Examples) Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings.
