With reference to fig. 1 to 3 of the specification, the multilayer composite pressure sensitive adhesive label according to a preferred embodiment of the present invention can be combined and derived to form a plurality of pressure sensitive adhesive labels along with the changes of the face material, the adhesive type and the pressure sensitive adhesive material. Fig. 1 shows the overall structure of the multilayer composite pressure-sensitive adhesive label, which is a label layer 1, a label layer 2 and a liner layer 3 for printing or printing in this order from top to bottom.

Wherein, label layer 1 and label layer 2 are all compounded by face material layer (11,21), adhesive layer (12,22) and pressure sensitive adhesive material layer (13,23) in proper order and are constituteed. Preferably, the label layer 1 and the label layer 2 are sequentially laminated and adhered from small to large, so that the label layers (1,2) can be conveniently separated layer by layer, and the information of the face material layers (11,21) can be displayed layer by layer.

The top surfaces of the surface material layers (11,21) display printing patterns, characters, frames, printing information and the like;

the adhesive layer (12,22) can be selected as a separable adhesive layer, a permanent adhesive layer or a pressure-sensitive removable adhesive layer, and is mainly used for bonding the bottom surface of the face material layer (11,21) and the top surface of the pressure-sensitive adhesive material layer (13,23) according to the application and the requirement of the label, so that the face material layer (11,21) and the pressure-sensitive adhesive material layer (13,23) form a whole, namely the label layer (1,2) forms a whole;

the pressure-sensitive adhesive material layer (13,23) is composed of a pressure-sensitive adhesive base material (131,231) and a pressure-sensitive adhesive (132, 232). Wherein, the pressure-sensitive adhesive base material (131,231) is used as a carrier of the lower pressure-sensitive adhesive (132,232), the pressure-sensitive adhesive (132,232) is loaded on the lower part, and the upper part is jointed with the surface material layer (11,21) for receiving the printing information through the adhesive layer (12, 22). The label layer 1 is adhered to the label layer 2 by a pressure sensitive adhesive 132. The label layer 2 is adhered to the liner layer 3 by a pressure sensitive adhesive 232. The pressure-sensitive adhesive material layer (13,23) can be made of transparent material, semitransparent material or opaque material according to requirements. If a transparent material or a semitransparent material is selected, a disposable separable adhesive layer or a pressure-sensitive type removable adhesive layer is selected by matching the upper adhesive layers (12,22), after the surface material layers (11,21) are separated, the lower layer information can be seen through the lower transparent pressure-sensitive adhesive material layers (13,23), and a plurality of labels with the same size or different sizes are combined and overlapped together, so that the possibility is provided for displaying the multilayer information. The required information can be printed in advance, and when one layer is uncovered, the new information of the lower layer can be seen; the information can also be supplemented directly on the surface of the subjacent surface material layer (11,21) after the uncovering. If the opaque material is selected, the top surfaces of the pressure-sensitive adhesive base materials (131,231) can also bear advertisements or information to be displayed, and the information can be displayed in a multi-layer manner by multi-layer pasting;

the liner layer 3, which is composed of the silicone oil layer 31 and the base material layer 32, forms a silicone liner for isolating and protecting the label layers (1, 2).

The top view of the front half-uncovered state of the present invention is also an embodiment of the present invention with reference to the attached fig. 4 of the specification. The technical characteristics of the multilayer composite pressure-sensitive adhesive label can be further understood by showing the figure. The top layer is a surface material layer 11 for bearing commodity price information, the adhesive layer 12 on the back is a separable adhesive layer, and the surface material layer 11 and the pressure-sensitive adhesive material layer 13 on the lower layer are adhered together, so that the surface material layer 11 and the pressure-sensitive adhesive material layer 13 form a whole. When the separation is needed, the surface paper layer 11 and the pressure-sensitive adhesive material layer 13 can be easily separated by removing the surface paper layer 11. The back surface of the underlying pressure-sensitive adhesive substrate 131 is coated with a pressure-sensitive removable adhesive. The pressure sensitive adhesive substrate 131 is made of transparent material, such as polypropylene film (OPP), polyester film (PET), polyethylene film (PE), etc. The reason for selecting the pressure sensitive adhesive material of the transparent material is that the transparent pressure sensitive adhesive material layer 13 is peeled off from the surface material layer 11, and the price information of the lower layer can be seen through the pressure sensitive adhesive material layer 13. If a plurality of labels with the same functions are overlapped together, the next layer of new price information can be displayed when one layer is uncovered, and the possibility of rapidly updating the information of the commodities is provided.

Preferably, in order to facilitate the separation of the face material layers (11,21), the pressure-sensitive adhesive material layers (13,23) are produced by stamping so that the peripheral dimensions thereof are smaller than those of the face material layers (11,21) and the face material layers (11,21) are obviously protruded from the pressure-sensitive adhesive material layers (13,23) below. In view of the convenience of removal, the size of the projecting portion is preferably not less than 0.5mm for easy grasping. Of course, referring to fig. 2 and 3, the facestock layer (11,21) of the label layer 1 and/or the label layer 2 may also be of the same size as the layer of pressure-sensitive adhesive material (13,23), where the same size refers to the same cross-sectional area in the transverse direction, such that the facestock layer (11,21) and the layer of pressure-sensitive adhesive material (13,23) are completely coincident. In addition, the adhesive layer (12,22) has dimensions comparable to those of the pressure-sensitive adhesive material layer (13,23) so that the back of the projecting portion of the face material layer (11,21) is rendered tack-free to facilitate grasping of the projecting portion of the face material layer (11,21) and separation thereof from the underlying pressure-sensitive adhesive material layer (13, 23). If a permanent composite adhesive layer is used, the pressure-sensitive adhesive material layer (13,23) is integrated with the surface material layer (11, 21). Grasping the protruding portion of the facestock layers (11,21) will remove the entire label layer 1 or label layer 3 from the object. The design of the technology provides a more convenient technical scheme for separating the label from the attached object or the lower layer material.

In one embodiment, the layer of pressure sensitive adhesive material (13,23) is a translucent or transparent layer. After the surface paper layers (11,21) are uncovered, new price information printed in advance on the lower layer can be seen through the semitransparent or transparent layer, and the transparent material can form effective protection on the surface material layer 21 on the lower layer, so that the new price information has the functions of water resistance, oil resistance, friction resistance and the like. The price can be updated frequently by adopting the method that labels with preset price are printed in advance and are pasted layer by layer in an automatic labeling machine mode. When in use, the price information of the label on the lower surface material layer 21 can be displayed only by taking off the upper surface material layer 11. In this embodiment, the tags are primarily used for clothing season change price updates. The surface material is coated paper. The coated paper is printed with a price frame. The commodity price is printed in the frame, and the sizes of the surface materials are respectively 37mm X17 mm and 45mm X27 mm. The face stock perimeter is 1-4mm larger than the underlying layer of transparent pressure sensitive adhesive material (13,23) to form a raised portion, i.e., tab. The lower large label and the upper small label can be adopted, and the mode of overlapping and pasting with the same size can also be adopted. And when the convex tongue part is grabbed every time the price is adjusted, the surface material layer 11 and the pressure-sensitive adhesive material layer 13 can be separated, and the new price of the lower layer label printed in advance can be displayed, so that a convenient and efficient solution is provided for updating the price in season change.

In another embodiment, multilayer composite pressure sensitive adhesive labels have proven useful in the logistics industry. The surface material layers (11,21) can adopt heat-sensitive paper, heat-sensitive synthetic paper or coated paper, and writing paper. The material layer (11,21) is printed with logistics information. The intermediate layer (13,23) of pressure sensitive adhesive material is an opaque layer and the top surface of the pressure sensitive adhesive substrate (131,231) is printed with advertising information. The adhesive layers (12,22) are provided as separable adhesive layers. When the article is delivered to the customer, the bill printed with the customer information or the bar code for identifying the customer information on the uppermost layer is signed by the customer, the courier can take away the bill for storage, the surface of the packing box has no any information of the customer, the privacy is protected, and the separated middle layer, namely the pressure-sensitive adhesive base materials (131,231) are printed with the advertisement information, so that the brand image of an enterprise is greatly facilitated to be displayed.

In a third embodiment, the multilayer composite pressure sensitive adhesive label can also be used in logistics or industrial applications, and the adhesive layers (12,22) are removable pressure sensitive adhesive layers. After the face stock layer (11,21) is separated from the pressure-sensitive adhesive material layer (13,23), the face stock layer (11,21) coated with the removable pressure-sensitive adhesive remains tacky without damaging the face stock layer (11,21) and without leaving adhesive residue on the underlying pressure-sensitive adhesive material layer (13,23), and after removal, the removed face stock layer (11,21) can be re-applied and repositioned.

In a fourth embodiment, the multilayer composite pressure-sensitive adhesive label is formed by integrating the facestock layer (11,21) with the pressure-sensitive adhesive material layer (13,23) after the adhesive layer (12,22) is a permanent adhesive layer. When the label needs to be separated from the attached object, a label made of a removable pressure-sensitive adhesive layer is selected for many embodiments, and the tab technology of the utility model can effectively remove the label layer from the surface of the attached object integrally.

It will be clear to the skilled person that the layers of facestock (11,21) are effectively separated from the layers of pressure sensitive adhesive material (13, 23). The prior art generally uses surface parting lines to cut through the facestock layers (11,21) without damaging the underlying pressure sensitive adhesive material layers (13, 23). In the separation mode, if the pressure of the die cutting machine is unstable or the cutter is improperly adjusted, the die cutting depth is shallow or deep; if the punching depth is insufficient, the two can not be peeled off; when the stamping depth of the die-cutting rule is too deep, or the lower pressure-sensitive adhesive material layer (13,23) is cut through or cut wound, the stability of the cutter can influence the uncovering effect, the utility model discloses a protruding tongue mode can effectively solve above-mentioned problem.

Depending on the field of application, it is necessary to select a suitable binder.

The pressure sensitive adhesive substrate (131,231) may be selected in a variety of embodiments depending on the application. Transparent materials and opaque materials are also available; with selective paper based, and also selective film based, or specialty materials. Preferably, the multi-layered information overlay display is generally made of transparent or semi-transparent materials such as polypropylene film, polyester film, polyethylene film or synthetic film, and semi-transparent materials such as foam paper, parchment paper, glassine paper, and grease-proof paper.

The choice of the face material layer (11,21) is that, in some embodiments, the face material layer (11,21) is preferably an opaque layer, and the surface of the face material layer (11,21) is pre-set with display information as information that needs to be carried instantly and variably. Generally, the surface material layer (11,21) is usually made of paper material, which is mainly considered to receive printing information reliably on the surface, and includes but is not limited to coated paper, writing paper, thermal paper, fluorescent paper, etc., and may also be made of film material.
