Description

  The present invention relates to a voucher base sheet having an adhesive layer that can be affixed to a delivery object, and a continuous voucher in which a surface sheet in which a peeling slip portion and a sticking slip portion are arranged on the same surface is bonded by an adhesive layer. In more detail, under the condition that the release layer on the back side of the top sheet of the release slip portion is formed by offset printing, the strength of peeling the release slip from the slip varies between sheet slips or even within one slip. The present invention relates to a continuous slip and a method for manufacturing the same which can supply a stable and stable product.

  2. Description of the Related Art Conventionally, delivery slips have been widely used for delivery of delivery products such as department stores and mail order companies, and delivery parcels of shipping companies. In particular, a delivery slip or receipt slip and a sticker slip are pasted on a slip base material, and a delivery slip arranged side by side can be printed at high speed using a non-impact printer as a continuous form. Widely used. Also, in order to make it easier to peel off the delivery slip from the slip base material, the delivery slip is weakened by forming an adhesive shielding layer (peeling layer) by solid printing on a part of the adhesive layer of the slip base material. The peeling start part which becomes a flicker at the time of peeling start of this was produced (patent document 1).

  The release layer for weakening the adhesive force of the adhesive layer needs to be uniformly and solidly formed opposite to the place of the adhesive layer. On the other hand, a continuous form delivery slip (continuous slip) is formed by offset printing except for the adhesive layer formation conditions, which is a restriction condition for manufacturing this kind of continuous slip. . Therefore, when forming a peeling layer by offset printing, there exists a problem that the biting part of a printing plate will arise as a non-printing part, as shown to patent document 2. FIG.

On the other hand, as shown in FIG. 4, the printing of the release layer is divided into two units of offset printing section, the A pattern is printed on one printing section, the B pattern is printed on the other printing section, and the peeling is performed. It is possible to carry out the formation of the layers continuously in the flow direction. In this case, when used as a sheet-fed (sheet-like) slip that is finally used from a continuous slip, the print density varies between units, and the delivery slip (peel slip) between slips becomes peelable. There arises a problem that a difference occurs and the separation becomes difficult or the separation is too light and the delivery slip is dropped during handling.

This release paper is made of paper, fabric, plastic film, etc., and the upper surface, that is, the surface on the side of the pressure-sensitive adhesive layer is subjected to a release treatment with a silicone-based release agent or the like. The thickness of the release paper is not particularly limited, but is usually about 20 to 200 μm, preferably about 40 to 100 μm.

(Continuous slip manufacturing method)
The continuous slip manufacturing method of the present invention will be described in detail below with reference to examples.
In the method for producing a continuous slip described above, at least a printing press having an offset printing unit of two or more units is used.
(Step 1)
The 1st peeling layer 2 is formed in the back surface of the said surface sheet 10 by the offset printing part of a 1st unit.

(Step 2)
Since the first release layer 2 formed in Step 1 is formed by the offset printing method, when setting the sheet-like offset printing plate on the plate cylinder, both ends of the printing plate are inserted into the grooves of the plate cylinder. When the cylindrical shape is used, the biting portion attached to the groove becomes a non-printing portion, and a gap (margin) 4 is generated. (See Figure 1 and Patent Document 2)
According to the gap 4 position, the second release layer 3 is formed in the offset printing section of the second unit, and the release layer is continuously formed in the printing flow direction.

  On the surface of the top sheet, for example, the above-described offset printer is used to perform inline marking of a release slip represented by a sticker slip and a delivery slip and printing of a picture attached thereto by offset printing. In addition, marginal punches can be continuously formed at both ends of the long surface sheet.

  The slip base material sheet having the release paper and the pressure-sensitive adhesive layer can be one that is commercially available as a so-called tack paper, and can form a sealing layer on the surface of the tack paper, or can be in the form of a long tack paper. Marginal punches can be continuously formed at both ends at both ends.

  Adhesive layer of the surface sheet on which the release layer is formed, and the tack paper, continuously in the flow direction, using a flexo printing method or a gravure printing method, with both marginal punches combined. Is applied, and both are bonded together. Half-cut 8 processing is performed from the surface sheet side in a state where the surface sheet and the tack paper are adhered to the collating machine in-line or in a separate line. Further, the perforation 9 is processed on the surface sheet and the tack paper in a state where the surface sheet and the tack paper are bonded.

  In the above manufacturing method, as shown in FIG. 3, the perforations 9 are used to form a continuous slip in a zigzag form. The continuous slip of the present invention uses a non-impact printer or the like as a continuous form in such a form, and at a predetermined place of a release slip and a sticker slip used as a delivery slip or a receipt slip, a delivery address, Names can be printed and processed at high speed.
