Problems solved by technology

[0008] The purpose of the present invention is to provide a self-adhesive label and its special film to overcome the problem of thick self-adhesive label surface material, thick backing paper, thick glue layer, easy to lift, formula needs to be adjusted according to seasonal climate changes, and release force requirements. The shortcomings of adjusting according to the change of material thickness (stiffness); and overcome the shortcomings of thermal transfer labels that cannot be used as product sealing labels, not suitable for use on uneven rough surfaces, and easy to burr.

Embodiment 1

[0035] Embodiment one: if figure 1 , figure 2 As shown, referring to the formulation and process requirements of the prior art (Chinese patent CN200710022723.1 or Chinese patent CN02134698.4), a 32-micron thick, biaxially stretched high-temperature resistant PET transparent film roll is selected as the base tape layer (1) , coating a layer of 2-micron-thick separating agent on one side as a release layer (2) and a protective layer. A layer of 5 micron thick PE transparent film (3) is coated on the release layer (2), or a layer of 8 micron thick PET transparent film (3) is compounded. Then reverse print the necessary printed information layer (4) on it, and then print or coat the hot melt adhesive layer (5) on the printed information layer (4). Finally, after die-cutting and waste discharge, the label units (7) composed of the transfer layer (6) can be left on the baseband layer (1). In order to facilitate the automatic use of the thermal transfer machine, it can be cut int...

Embodiment 2

[0036] Embodiment two: if figure 1 , image 3 As shown, choose a 25 micron thick, biaxially stretched high temperature resistant PET transparent film roll material as the base belt layer (1), and coat a layer of 2 micron thick release agent on one side as the release layer (2) and protective layer .

[0037] Choose another 28g / m 2 The textured anti-counterfeiting paper (3) containing random fibers (8) has the necessary text, pattern information and identification serial number printed on the front; or, the necessary text, pattern information and identification serial number are reverse printed on the release layer (2) .

[0038] Laminate the textured anti-counterfeiting paper (3) prepared in the previous step on the release layer (2). And coat one layer of hot melt adhesive layer (5) on its back side. Each label unit (7) is scanned and photographed, and its photo is stored and filed in the database of the computer query system with its serial number as the file name.

Embodiment 3

[0041] Embodiment three: as Figure 4 As shown, a 22-micron-thick, biaxially oriented high-temperature-resistant PET transparent film roll is selected as the base layer (1), and a layer of 3-micron-thick release agent is coated on one side as the release layer (2). A layer of PE transparent film (3) with a thickness of 6 microns is coated on the release layer (2), or a layer of PET transparent film (3) with a thickness of 8 microns is compounded. Then, it can be rolled and packaged to make the special film for dry glue label of the present invention.

Abstract

The invention provides a self adhesive label and a special film thereof. The self adhesive label is composed of a baseband layer and a transfer layer, wherein, the transfer layer comprises a disengaging layer, a paper / film layer, a printing information layer and a hot melt adhesive layer. The transfer layer undergoes die cutting and is discharged waste to become label units separated from each other. The self adhesive label and special film thereof solve the disadvantages that the base paper, the face material and the adhesive layer of the self adhesive label are thick, the self adhesive label is convenient to uncover, the formula needs to be adjusted in accordance with the season climates and the release force needs to be adjusted in accordance with the thickness of material; and solve the disadvantages that the thermal transfer label can not be used as a product sealing label, and is not suitable for using on uneven rough surfaces; and the special film of the self adhesive label is convenient for users to produce self adhesive label.

Description

technical field [0001] The invention relates to the technical field of label printing, in particular to a heat-transfer label and its special material having both technical advantages of self-adhesive labels and heat-transfer labels. Background technique [0002] "Baidu Encyclopedia" has this introduction about "self-adhesive labels": Self-adhesive labels are also called self-adhesive labels, instant stickers, sticky notes, pressure-sensitive paper, etc., which are made of paper, film or special materials, and coated on the back. There is a self-adhesive adhesive, a composite material with a silicon-coated backing paper (release backing paper) as the protective paper, and after printing, die-cutting, waste discharge, etc., it becomes a finished label that is separated from each other. When applying, you only need to peel off the backing paper and press it lightly to stick to the surface of various substrates, or use a labeling machine to automatically label on the production...
