Description

Environmentally friendly and separable to the middle layer logistics label

technical field

The utility model relates to a structural improvement technology for IPC classification G09F marks, labels or nameplates, in particular to environmental protection and separable intermediate layer logistics labels.

Background technique

The logistics label is a kind of self-adhesive or self-adhesive label, which is usually a composite material with paper, film or special materials as the fabric, adhesive on the back, and silicon-coated maintenance paper as the backing paper.

There are many traditional coating techniques used to manufacture logistics labels, mainly using roll coating, blade coating and high-pressure casting coating, etc. It is required to ensure the average rationality of coating to the greatest extent, and prevent air bubbles and pinholes. occurrence, to ensure the coating quality. The self-adhesive printing products are mainly commodity labels and signs, and the composite paper is prefabricated by a paper product processing factory. superior. After printing, use the knife line to emboss, peel off the excess part of the blank, and leave a certain shape of the printed matter on the release paper. When using, peel off the finished product and paste it on the commodity or packaging. In addition, in addition to paper, the substrates include metal foils and films.

Currently widely used separable logistics labels mainly include three-layer structure, namely bottom paper, middle layer and face material. Wherein, as a supporting structure, the intermediate layer can be a film of 20-80um, coated paper of 30-100gsm, glassine or other papers. The three-layer material is glued and compounded and then die-cut to form a separable logistics label. However, from the microscopic plane structure, the label structure is actually as many as six to eight layers.

The existing logistics label products have many layers of structure and cumbersome processing process, resulting in complicated production process and low production efficiency. If paper is used as the label printing layer, the peeling force is too high, it is not easy to peel off and easy to tear, and the peeling force is too low, the label will fall off automatically, which will affect the final label performance. If the printing layer of the anti-counterfeiting label is made of film material, the surface of the paper label with rough surface and high oil absorption and water absorption, the surface of the back of the printing layer is coated with a release layer, which requires a large amount of coating. Because the release agent is usually expensive, production The preparation cost is high. In addition, from the perspective of resource consumption and cost, full-width laminating, or using full-width film or paper as the intermediate layer, requires a lot of ecological and environmental resources, and the economic cost is high. After the release agent is applied, the coating is applied to form an intermediate layer with printing and isolation functions. Due to the rough surface of the back of the label printing layer, it will inevitably cause uneven peeling force and local tearing. From the perspective of the final application, the composite structure has high stiffness, and it is easy to fall off when the rod enters the printer during printing. When the peeling force is increased, the final labeling is inconvenient; and it is difficult to control processes such as die-cutting and waste removal during the manufacturing process. In a word, under the prior art, if the anti-counterfeiting label technology is directly applied to the logistics label, the result is high cost and unstable performance.
