Description

Technical Field

[0001] The utility model relates to the technical field of label films, in particular to a PVC heat shrinkable label film. Background Art

[0002] A heat shrinkable label film is a label film printed with special ink. During the label pasting process, when heated (about 70°C), the shrinkable label film will quickly shrink along the outer contour of the container and closely adhere to the surface of the container. Since the film itself has high transparency, the label has bright colors and good gloss, making the packaging pattern on the bottled beverage more vivid, realizing a 360° label design, highlighting the image on the supermarket shelf, and it is the main packaging form for the outer trademarks of current functional beverages such as tea beverages, fruit juices, dairy products, and cosmetics, high-grade alcoholic products, etc.

[0003] The existing Chinese patent document CN202023221909.X discloses a PETG heat shrinkable film label. A palm bonding layer formed by palm glue is smeared on the surface of one end of the PETG heat shrinkable film label, and the other end of the PETG heat shrinkable film label covers the outside of the palm bonding layer; wherein, the thickness of the PETG heat shrinkable film label is 53 - 203 μm, and the thickness of the palm bonding layer is 5 - 8 μm. The palm bonding layer of the PETG heat shrinkable film label of the utility model has low toxicity, high safety, and remarkable palm bonding effect, and there will be no phenomenon of internal overflow glue and external overflow glue.

[0004] However, the above patent has certain defects in use. Since the heat label film is mostly applicable to food packaging, and this heat shrinkable label film mostly uses an adhesive layer of chemical adhesives for bonding, it is easy to be rubbed off, which is not conducive to the use of personnel.

[0005] Therefore, a PVC heat shrinkable label film is proposed here to solve the above problems. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a PVC heat shrinkable label film.

[0007] The utility model is realized by adopting the following technical scheme:

[0008] A PVC heat shrinkable label film includes a label film main body. The label film main body includes an ink coating, a PVC layer, and an adhesive layer. The ink coating, the PVC layer, and the adhesive layer are laminated and fixedly connected in sequence from top to bottom. A card slot is provided on one side of the front surface of the label film main body. There are multiple card slots, which are arranged vertically and evenly at equal intervals;

[0009] On the back of the label film body, on the side away from the card slot, there are multiple clamping blocks. There are multiple clamping blocks, which are arranged vertically and evenly at equal intervals. The size of the clamping blocks is adapted to the card slot. The inside of the clamping blocks is hollow, and there is an adhesive in the inside of the clamping blocks. There are multiple glue outlet holes on the surface of the clamping blocks, and the glue outlet holes are communicated with the inside of the clamping blocks.

[0010] There are multiple tearing holes on the label film body. The tearing holes are arranged vertically and evenly at equal intervals. At the upper and lower ends of the tearing holes, there are symmetrically arranged notches.

[0011] On the upper surface of the ink coating layer, there is an ultraviolet absorption layer, and on the upper surface of the ultraviolet absorption layer, there is an ultraviolet barrier layer.

[0012] On the upper surface of the ultraviolet barrier layer, there is a wear-resistant protective layer.

[0013] There is an antioxidant layer between the ultraviolet absorption layer and the ink coating layer.

[0014] The present utility model has the following beneficial effects compared with the prior art:

[0015] 1. By arranging clamping blocks and card slots on the label film body, when the label film is placed on a commodity, the clamping blocks can be inserted into the card slots to form a mechanical lock. In addition, the hollow structure and glue outlet hole design inside the clamping blocks allow the adhesive to be released by squeezing the clamping blocks when needed, further enhancing the fixing effect, so that the label film can be more firmly fixed on the commodity during use and is not easy to fall off;

[0016] 2. By arranging tearing holes and notches on the label film body, the tearing holes and notches provide stress concentration points of the label film, enabling users to more easily separate the label film from the commodity surface when tearing, so that the label film is easy to tear and remove after use and will not cause damage to the commodity.

Specific embodiments

[0024] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0025] The present utility model will be further described below with reference to the accompanying drawings

[0026] As Figures 1 to 6 shown, a PVC heat-shrinkable label film includes a label film body 1. The label film body 1 includes an ink coating 7, a PVC layer 5, and an adhesive layer 6. The ink coating 7, the PVC layer 5, and the adhesive layer 6 are laminated and fixedly connected in sequence from top to bottom. On one side of the front surface of the label film body 1, there are provided a plurality of card slots 2, which are longitudinally arranged and evenly spaced;

[0027] On the back surface of the label film body 1, on the side far from the card slot 2, there are provided a plurality of card blocks 3, which are longitudinally arranged and evenly spaced. The size of the card blocks 3 is adapted to that of the card slots 2. The inside of the card blocks 3 is hollow, and an adhesive is provided inside the card blocks 3. The surface of the card blocks 3 is provided with a plurality of glue outlet holes 31, and the glue outlet holes 31 are communicated with the inside of the card blocks 3.

[0028] A plurality of tear holes 4 are provided on the label film body 1, which are longitudinally arranged and evenly spaced. At the upper and lower ends of the tear holes 4, notches 41 are symmetrically provided. The design of the tear holes 4 and the notches 41 makes it convenient to tear and remove the label film after use without damaging the commodity

[0029] An ultraviolet absorption layer 9 is provided on the upper surface of the ink coating 7, and an ultraviolet barrier layer 10 is provided on the upper surface of the ultraviolet absorption layer 9. The ultraviolet absorption layer 9 can be an ultraviolet PET film. The ultraviolet absorption layer 9 is used to absorb and shield ultraviolet radiation to protect the ink coating 7 and the PVC layer 5 from ultraviolet damage. The ultraviolet barrier layer 10 further blocks the penetration of ultraviolet rays and improves the weather resistance of the label film.

[0030] The upper surface of the ultraviolet ray barrier layer 10 is provided with an abrasion-resistant protective layer 11. The abrasion-resistant protective layer 11 generally has high hardness and wear resistance, and can form a protective barrier on the surface of the label film to resist the damage of external friction and impact, and prevent being scratched or worn during daily use.

[0031] An antioxidant layer 8 is provided between the ultraviolet ray absorption layer 9 and the ink coating layer 7. The antioxidant layer 8 generally contains chemical substances that can inhibit oxidation reactions. These substances can react with oxygen or other oxidants in the air, thereby slowing down or preventing the oxidation process of the ink coating layer 7.

[0032] The working principle of the present utility model is as follows: during use, the cut PVC heat-shrinkable label film is placed on the surface of the commodity, and the label film is heated. During the heating process, the PVC layer 5 undergoes heat shrinkage and closely adheres to the surface of the commodity. The label film is pressed, and the adhesive layer 6 on the back of the label film body 1 is first adhesively fixed.

[0033] Then, the clamping block 3 is snapped into the clamping groove 2. When the clamping block 3 is inserted into the clamping groove 2, mechanical locking is formed. At the same time, the clamping block 3 is pressed, and the adhesive in the clamping block 3 oozes out of the glue outlet hole 31 and adheres to the surface of the commodity. Through the dual actions of mechanical locking and the adhesive, the fixing effect is further enhanced, greatly enhancing the adhesive effect and effectively avoiding the detachment of the label film.

[0034] The above embodiments are only the preferred embodiments of the present utility model, and the protection scope of the present utility model cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the protection scope required by the present utility model.
