"At least one" appearing in the embodiments of the present invention refers to one or more, and "more than one" refers to two or more.

[0027] "Scope" disclosed in the utility model is defined in the form of lower limit and upper limit, and a given range is defined by selecting a lower limit and an upper limit, and the selected lower limit and upper limit define the boundary of a particular range. The scope defined in this way can be inclusive or exclusive of end values, and can be arbitrarily combined, that is, any lower limit can be combined with any upper limit to form a range. For example, if the scope of 60-120 and 80-110 is listed for a particular parameter, it is understood that the scope of 60-110 and 80-120 is also expected. In addition, if the minimum range values ​​1 and 2 are listed, and if the maximum range values ​​3, 4 and 5 are listed, the following ranges can all be expected: 1-3, 1-4, 1-5, 2-3, 2-4 and 2-5.

In addition, when a parameter is expressed as an integer ≥ 2, it is equivalent to disclosing that the parameter is, for example, an integer of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc.

[0028] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0029] When conventional film packaging materials are printed with water-based inks and UV inks, the patterns printed with water-based inks and UV inks have the problem of easy falling off due to the low adhesion of water-based inks and UV inks to plastic films. Therefore, conventional film packaging materials are not suitable for printing patterns with water-based inks and UV inks.

[0030] To this end, the utility model provides a film packaging material, which comprises at least one group of plastic film layers, and at least one side of the at least one group of plastic film layers is provided with an ink adhesion layer.

[0031] The ink adhesion layer refers to a coating to which the ink can adhere firmly.

[0032] At least one side of at least one group of plastic film layers is provided with an ink adhesion layer means that: when the film packaging material has only one group of plastic film layers, the ink adhesion layer can be provided on one side or both sides of the plastic film layers; when the film packaging material has multiple groups of plastic film layers, the ink adhesion layer can be provided on one side or both sides of one group of plastic film layers, or the ink adhesion layer can be provided on one side or both sides of multiple groups of plastic film layers.

[0033] The film packaging material of the utility model comprises an ink adhesion layer. When water-based ink and UV ink are used for printing, the ink adhesion layer can improve the adhesion of the ink, thereby firmly adhering the ink to the plastic film layer, improving the problem of pattern shedding when printed with water-based ink or UV ink. Therefore, the film packaging material of the utility model can be suitable for printing with water-based ink and UV ink.

[0034] In an embodiment of the utility model, the film packaging material further comprises a printed pattern layer, and the printed pattern layer is arranged in contact with the ink adhesion layer.

[0035] The printed pattern layer refers to a pattern layer formed by printing with ink, which can display relevant information of the product. The printed pattern layer is laminated with the ink adhesion layer, which means that the ink is printed on the surface of the ink adhesion layer to enhance the adhesion of the ink.

[0036] In an embodiment of the present invention, the film packaging material further includes an aluminum coating layer.

[0037] The aluminum coating layer refers to an aluminum layer formed by vacuum evaporation or other methods. The aluminum coating layer can be provided on the plastic film layer or on the printed pattern layer. The provision of the aluminum coating layer can make the film packaging material have metallic luster, and can give the film packaging material metal properties, improve its folding resistance, toughness, etc.

[0038] In an embodiment of the present invention, the film packaging material further comprises a UV varnish layer, and the UV varnish layer is provided as the outer surface layer of the film packaging material.

[0039] The UV varnish layer is formed by UV varnish, which is also called UV varnish. It is a transparent coating that can be hardened from liquid to solid by UV lamp irradiation, thereby forming a film packaging material with a scratch-resistant surface. That is, the setting of the UV varnish layer can improve the wear resistance and chemical resistance of the film packaging material.

[0040] In an embodiment of the present invention, the film packaging material further comprises a hot melt adhesive layer, and the hot melt adhesive layer is provided as an inner surface layer of the film packaging material.

[0041] The innermost layer of conventional film packaging materials is a pressure-sensitive adhesive layer to facilitate bonding and fixing with the packaged items. The adhesive layer needs to be protected by release paper or release film. As disposable materials, release paper or release film is not easy to degrade and may cause pollution to the environment. On the other hand, the cost of release paper and release film is high, which will increase the cost of packaging materials.

[0042] In this embodiment, the innermost layer of the film packaging material is a hot-melt adhesive layer that is heated and glued. Since the hot-melt adhesive layer is not sticky after being coated and cooled, it does not need release paper or release film protection, thus saving costs and not causing environmental pollution.

[0043] In an embodiment of the present invention, the film packaging material further comprises a composite adhesive layer, and the composite adhesive layer is arranged between the two groups of plastic film layers.

[0044] The composite adhesive layer is a bonding layer formed by composite adhesive. The composite adhesive is a special adhesive for thermal composite made of thermoplastic polyester resin. It has strong adhesion to various films. By bonding two sets of plastic film layers through the composite adhesive layer, the separation of plastic film layers can be avoided.

[0045] In an embodiment of the present invention, the ink adhesion layer is selected from one of acrylic paint, polyurethane paint, and vinyl paint.

[0046] Acrylic paint, also known as acrylic polymer paint, is a paint based on acrylic resin, which is made by adding chlorosulfonated polyethylene rubber, weather-resistant pigments and fillers to acrylic resin. Acrylic paint has good adhesion to plastic products, so it can bond with plastic film layers, and acrylic paint has good compatibility and can cooperate with water-based inks and UV inks, so that water-based inks and UV inks can adhere firmly to its surface.

[0047] Both polyurethane and vinyl coatings have good adhesion to plastics and provide good ink adhesion.

[0048] In an embodiment of the present invention, the thickness of the ink adhesion layer is 1 μm to 10 μm.

[0049] In an embodiment of the present utility model, the plastic film layer is selected from one of PET shrink film, PETG shrink film and aluminized shrink film.

[0050] PET shrink film, PETG shrink film and aluminized film thereof include PET shrink film, PETG shrink film, PET aluminized shrink film and PETG aluminized shrink film.

[0051] PET shrink film is a polyethylene terephthalate film, which has excellent transparency and gloss, can provide good visual effects, and has excellent mechanical properties, heat resistance and cold resistance, and can adapt to a variety of application environments; PETG shrink film is a polyethylene terephthalate-1,4-cyclohexane dimethanol film, which has higher transparency, better gloss and is easier to print than PET shrink film.

[0052] The utility model also provides a battery, including a battery body and the above-mentioned film packaging material, wherein the film packaging material is coated on the battery body. The specific arrangement of the film packaging material refers to the above-mentioned embodiment. Since the battery of the utility model adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
