Description

  The present invention relates to a method for producing a laminated label in which two sheets are bonded, and in particular, one of the two sheets is made of a resin film so that the two sheets can be peeled off and cannot be reattached. The present invention relates to a method for producing an attached laminated label.

  Conventionally, when delivering a delivery, a delivery label in which delivery information such as the address, name, or name of the delivery source and delivery destination of the delivery is entered is used, and the delivery label in which the delivery information is entered is used as the delivery. The delivery is delivered to the delivery destination in accordance with the delivery information that is attached and written on the delivery label.

  Such a delivery label is configured such that a receipt slip brought back by a delivery company after delivery is delivered to a delivery destination is separable. When this delivery label is used, when the delivery is delivered to the delivery destination, a receipt stamp is pressed on the receipt, and the receipt is separated from the delivery label and brought back by the delivery company. It is managed that it was delivered to.

  In addition, in recent years, with a delivery label as described above, even for a sticker that remains attached to the delivery even after the delivery has been delivered to the delivery destination, There are many requests to separate from the delivery to avoid leakage.

  Here, a transparent film made of PE (polyethylene), PP (polypropylene) or the like is pseudo-bonded to the back surface of the sheet base material, and an adhesive layer is laminated on the back surface of the transparent film, and this adhesive layer is attached to cardboard or the like. A label to be worn is considered (see, for example, Patent Documents 1 and 2). Since such a label has a configuration in which the transparent sheet is pseudo-adhered to the sheet base material, it can be separated from the cardboard etc. by peeling the sheet base material from the transparent film after being attached to the cardboard etc. it can.
