Description

Technical Field

[0001] The utility model belongs to the technical field of battery labels, and in particular relates to a battery label without a bottom paper. Background Art

[0002] In the prior art, the more common battery labels are labels containing backing paper. The need to use backing paper increases the production cost of the label, and the peeled backing paper needs to be processed when the label is used, which increases the consumption of energy waste. Therefore, linerless battery labels came into being. Compared with traditional liner-containing labels (self-adhesive labels), linerless labels do not contain silicone release backing paper. On the one hand, when making labels, silicone release backing paper is not used, which reduces the production cost of the enterprise and reduces the generation of waste (scraps after cutting the backing paper, etc.); on the other hand, when using the label, the generation of waste (peeled backing paper) is avoided; furthermore, during transportation, storage and pasting, linerless labels can reduce the frequency of roll changes and the consumption of energy waste, which is in line with the national concept of energy conservation and environmental protection. Utility Model Content

[0003] In view of the problems raised by the background technology, the utility model studies and designs a bottom-paper battery label, the purpose of which is to provide a bottom-paper battery label that reduces production costs, avoids waste generation during use, reduces subsequent use costs, and can meet the needs of different customers.

[0004] The technical solution of this utility model:

[0005] A bottom-less paper battery label comprises a single-layer bottom-less paper battery label or a double-layer bottom-less paper battery label, wherein the single-layer bottom-less paper battery label comprises a battery heat-shrinkable bottom film, wherein an adhesive area is provided below the battery heat-shrinkable bottom film, an ink area is provided above the battery heat-shrinkable bottom film, a low-peeling release agent area is provided above the ink area, and the low-peeling release agent area fully covers the ink area; the double-layer bottom-less paper battery label comprises a battery heat-shrinkable bottom film, wherein an adhesive area is provided below the battery heat-shrinkable bottom film, a composite adhesive area is provided above the battery heat-shrinkable bottom film, a battery heat-shrinkable mask area is provided above the composite adhesive area, an ink area is provided above the battery heat-shrinkable mask area, and a low-peeling release agent area is provided above the ink area; or the double-layer bottom-less paper battery label comprises a battery heat-shrinkable bottom film, wherein an adhesive area is provided below the battery heat-shrinkable bottom film, a composite adhesive area is provided above the battery heat-shrinkable bottom film, an ink area is provided above the composite adhesive area, a battery heat-shrinkable mask area is provided above the ink area, and a low-peeling release agent area is provided above the battery heat-shrinkable mask area. Or a double-layer bottom paper-free battery label includes a battery heat shrinkable bottom film, an adhesive area is below the battery heat shrinkable bottom film, an ink area is above the battery heat shrinkable bottom film, a composite glue area is above the ink area, a battery heat shrinkable mask area is above the composite glue area, and a low-peeling release agent area is above the battery heat shrinkable mask area.

[0006] Preferably, the battery heat shrinkable bottom film is a modified PET / PET / PVC / PS film with a thickness of 12-55um.

[0007] Preferably, the battery heat shrinkable bottom film is a modified PET / PET / PVC / PS film with a shrinkage rate of 10-60%.

[0008] Preferably, the adhesive area has a thickness of 5-35 um.

[0009] Preferably, the adhesive in the adhesive area is a pressure-sensitive adhesive or a hot-melt adhesive.

[0010] Preferably, the adhesive area is evenly coated by roller coating or scraper coating. When coating the adhesive area, the adhesive can be fully coated or only the label wrapping area can be coated according to the layout requirements.

[0011] Preferably, the composite glue in the composite glue area is solvent-based / emulsion-based glue.

[0012] Preferably, the ink area is coated with ink by spraying, gravure printing or flexographic printing as required, and the ink area is patterned by spraying, gravure printing or flexographic printing.

[0013] Preferably, the low-peeling release agent area completely covers the ink area / battery heat shrinkable mask area.

[0014] Preferably, the low-peeling release agent area can be a release agent or other low-peeling coating, which is mainly used to improve the wear resistance of the label, make the label brighter and better looking, and contact with the adhesive area after winding to generate a suitable peeling force so that the label can be peeled off well. This is the key to the linerless label.

[0015] The beneficial effects of the utility model are as follows: 1. Streamlining the coating equipment. Compared with the traditional battery label with liner, the modified PET / PET / PVC / PS battery label without liner saves the process of compound transfer after gluing, and does not require additional compound pressing rollers and liner unwinding rollers; 2. Streamlining the production process. The traditional battery label with liner is to first apply silicon, then apply glue, then print, compound, and finally apply release agent. The modified PET / PET / PVC / PS battery label without liner can save the process of silicon coating, first print, compound, and finally apply release agent. , then apply low-peeling release agent, and finally apply glue. After the glue is applied, it is reeled through a winder. Paper tubes with an inner diameter of 3 inches and 6 inches can be used for reeling. The glue side is inward during reeling. During the reeling process, the glue surface is in contact with the low-peeling release agent surface. Because the surface of the low-peeling release agent is smooth and the peeling force is small, it will not affect the normal labeling during subsequent unwinding and use; 3. Reduce costs and waste. Do not use silicone release backing paper, reduce corporate production costs, and reduce the generation of waste during production and use, which is in line with the national concept of energy conservation and environmental protection.

[0029] Working principle: According to customer needs, a predetermined pattern is first printed on the surface of the battery heat shrinkable base film C to form an ink area B, and then a release agent is evenly applied on the ink area B. The selected release agent takes into account wear resistance, low peeling force, and good glossiness to form a release agent area A.
