Abstract

PURPOSE:To provide a mail form whose whole face can be unfolded without cutting off peripheral edges, in a sealed mail form to be dispatched by folding up and sticking after necessary items are written. CONSTITUTION:At peripheral edges or flaps at the time that a base material is folded back or layered, weak adhesive layers 12 to be adhered by application of pressure continuously or intermittently are formed. On the front and rear faces of the base material 11 including the weak adhesive layers 12, a printing layer is formed, the base material 11 is folded back or layered, and the weak adhesive layers 12 on opposing faces are stuck together. Thereafter, they are peeled off from the weak adhesive layers 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mail form in a sealed letter format, in which necessary items are printed, then folded, pasted and shipped.

[0002]

2. Description of the Related Art Conventionally, for notifications from financial institutions, public institutions, government offices, etc., after printing necessary items on a printer, etc., the mail form is folded and stuck in a sealed form, and is attached and sent. It is widely used that the information can be concealed and shipped by sticking with a pressure-sensitive adhesive and cutting out three sides from the perforation at the time of opening to develop it in a booklet form.

[0003]

However, in the case of this form, since the adhesive portion remains, it is not possible to see it in a fully developed state, and since the information printable area is limited by the existence of the adhesive portion, the amount of information is also large. In addition, there is a problem that it takes a lot of time and labor to cut the peripheral portion from the perforations at the time of opening the package, and further, unnecessary dust is generated.

[0004]

In order to solve the above-mentioned problems, the mail form according to the present invention has a continuous or discontinuous pressure applied to a peripheral portion or a folded portion when a base material is folded or laminated. To form a weak pressure-sensitive adhesive layer, which forms a printing layer on the front and back surfaces of the base material containing the weak pressure-sensitive adhesive layer, and folds or laminates the base material to form the weak pressure-sensitive adhesive layers on the opposite surfaces. After the close contact, it is configured to be peeled from the weak adhesive layer.

[0005]

Since the mail form of the present invention uses a re-peelable weak pressure-sensitive adhesive, the base material is not damaged when the peeling-opening is performed from the sealed form, and the printing layer may be transferred to the facing surface. There is no waste, and there is no waste of cutting and discarding the sewing machine part, and peeling is performed between the weak pressure-sensitive adhesive layers, and the entire surface can be viewed without leaving any adhesive part.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. The mail form of the present invention is a sheet that is folded in three or more and has a size of an ordinary envelope, and is used as a form of envelope by a planned folding line. FIG. 3 shows an embodiment using a sheet for folding in three. The mail form 11 in FIG. 3 is used by being folded into a Z shape by a planned folding line, the left column is the public information printing section X ₁ such as destination information, and the middle and right columns are the hidden information printing section Y ₁ , Y ₂ . This mail form is a continuous form, and can be separated into unit sheets by perforations t, and after printing, the marginal portion r for sending the printer can be separated from the perforations s.

The mail form 11 has a weak pressure-sensitive adhesive layer 12 formed on the periphery of the folded and overlapping surface. After the weak adhesive layer is applied and formed, printing is performed on the front and back surfaces of the mail foam substrate including the weak adhesive layer, and the printed and folded sheet is folded and sealed. Normally, high-quality white paper is used as the base material 11 of the mail foam, but if the surface is roughened by corona treatment or matte treatment, synthetic resin film such as PET, PE, PP, vinyl chloride, etc. is used. You can also do it. The weak pressure-sensitive adhesive layer 12 can use a pressure-sensitive adhesive mainly containing SBR (styrene-butadiene-rubber) as a resin component, water as a volatile component, and microsilica as a pigment component. Further, as an additive for improving printability, various dispersions, non-metal powders, etc. may be used in addition to microsilica.

The mail form of the present invention may be of any structure as long as it is folded and adhered to form a sealed letter. As another embodiment, for example, the form as shown in FIGS. Can be considered. Further, the planned bending line, the installation location of the weak adhesive layer, and the formation area thereof are provided as needed each time, and are not limited to these examples.

Further, the form of printing the information may be continuous paper or single-cut paper, and information that does not require confidentiality is appropriately printed in each information printing partition including the hidden information printing partition. be able to.

[0010]

According to the present invention, a weak pressure-sensitive adhesive layer that adheres when pressed is provided in the peripheral portion or the folded portion, and the weak pressure-sensitive adhesives on the surfaces facing each other when folded are adhered to each other. When the adhesive peels off, the base material is not damaged,
In addition, since the print layer does not transfer to the facing surface and is peeled off between the weak pressure-sensitive adhesive layers, printing can be performed on the entire front and back surfaces of the base material including the layer, and the information print section is greatly expanded. Further, the tear-off perforation portion for opening is not required, and the labor of opening can be saved. In addition, since the entire surface can be developed without leaving any adhesive portion, for example, drawing information such as graphs and tables can be viewed in a list, and the layout can be freely performed without being restricted by the printing position.
