Description

Technical Field

[0001] This utility model relates to the field of membrane production technology, specifically to a scratch-resistant, non-folding, white direct-output membrane. Background Technology

[0002] As living standards continue to improve, people's expectations for product packaging are also increasing. To enhance the aesthetics and visual impact of packaging, a transfer film is often laminated onto the surface of the packaging paper. This transfer film is usually composed of a PVC base film and a coating. However, the degradation process of PVC base film in the natural environment is relatively slow, which may cause certain pollution problems.

[0003] Faced with increasingly stringent national environmental protection requirements, the removal of plastics from packaging paper has become an urgent and important task. Currently, a common practice to achieve this goal is to remove the PVC base film from the surface of the packaging paper. However, the PVC base film not only serves as a carrier for the coating in packaging paper but also gives it excellent bending resistance. Therefore, after removing the PVC base film, the remaining transfer coating often cannot meet the stringent bending requirements of the packaging paper. This challenge necessitates finding new solutions to better meet environmental protection requirements while maintaining the aesthetics and practicality of packaging. Therefore, this case study was developed to address the aforementioned issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a scratch-resistant, non-folding, white direct-output film, which solves some of the existing background technology problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a scratch-resistant, non-folding white direct-output film, comprising: a polyvinyl chloride film, wherein the polyvinyl chloride film is in the form of a rectangular plate, the polyvinyl chloride film is embossed with fold-resistant texture grooves, and a fold-resistant layer is provided on the fold-resistant texture grooves by hot-melting;

[0006] The flexural layer comprises a phthalate layer and a styrene-acrylonitrile layer;

[0007] The phthalate layer and the styrene-acrylonitrile layer are thermally fused to the inside of the folding texture groove.

[0008] Preferably, the phthalate layer and the styrene-acrylonitrile mixed layer are embossed with scratch-resistant textured grooves, and a scratch-resistant layer is hot-melted onto the scratch-resistant textured grooves;

[0009] The scratch-resistant layer comprises silicon dioxide and aluminum oxide;

[0010] The silicon dioxide and stretchable alumina are thermally fused to the inside of the scratch-resistant textured groove.

[0011] Preferably, an adhesive layer is provided on the inner side of the fold-resistant textured groove and the scratch-resistant textured groove, and the adhesive layer is a hot melt pressure-sensitive adhesive.

[0012] Preferably, the thickness of the polyvinyl chloride film is between 0.5 and 1 mm.

[0013] Preferably, the thickness of both the fold-resistant layer and the scratch-resistant layer is between 0.25 and 0.3 mm.

[0014] Preferably, the depth of both the folding-resistant texture groove and the scratch-resistant texture groove is between 0.05 and 0.1 mm.

[0015] This invention provides a scratch-resistant, non-folding white direct-output film. It offers the following advantages: The folding-resistant layer of this film is a carefully blended mixture of a phthalate layer and a styrene-acrylonitrile layer. This combination not only enhances the film's folding resistance but also imparts excellent flexibility and impact resistance. Simultaneously, silica and alumina are incorporated into the scratch-resistant layer, forming a hard and wear-resistant surface after mixing, significantly improving the film's scratch resistance. Through a clever multi-layered structure design, a close synergistic effect is achieved between the layers. While each layer functions independently, the folding-resistant and scratch-resistant layers also support and reinforce each other, jointly enhancing the overall performance of the film. This multi-layered design allows the film to exhibit excellent stability and durability in various complex environments. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0022] Example

[0023] like Figure 1-3 As shown, the polyvinyl chloride film 1 is a rectangular plate, and the polyvinyl chloride film 1 is embossed with folding texture grooves, and a folding-resistant layer is provided on the folding texture grooves by hot melting;

[0024] Specifically, the flexural layer comprises a phthalate layer 2 and a styrene-acrylonitrile layer 3;

[0025] Specifically, the phthalate layer 2 and the styrene-acrylonitrile layer 3 are hot-melted to the inside of the folding texture groove.

[0026] Specifically, scratch-resistant textured grooves are embossed on the phthalate layer 2 and the styrene-acrylonitrile layer 3 mixed layer, and a scratch-resistant layer is hot-melted onto the scratch-resistant textured grooves;

[0027] Specifically, the scratch-resistant layer comprises silicon dioxide 4 and aluminum oxide 5;

[0028] Specifically, the silicon dioxide 4 and the extensible alumina 5 are hot-melted into the inner side of the scratch-resistant textured groove;

[0029] It should be noted that the above-mentioned design uses a combination of high-precision embossing wheels and coarse rubber wheels. After the scratch-resistant layer is hot-pressed by the embossing wheels, it is then rapidly cooled, causing a qualitative change in the original PVC film (which includes the scratch-resistant layer in the hot melt process), resulting in a strong three-dimensional effect. The formulation ratio of phthalate layer 2 and styrene-acrylonitrile layer 3 is adjusted, and conditions such as wheel temperature, plasticization degree, stretching ratio, and post-cooling temperature are adjusted using production equipment to change the internal molecular arrangement structure of PVC, thereby achieving the best effect of impact resistance and non-whitening. The material temperature, wheel temperature, production speed, and stretching speed ratio between each cooling section are well controlled to reduce the film's ridges and shrinkage rate, increase the film's flexibility, and ensure a uniform and flat film thickness. By utilizing a unique embossing wheel system design technology, a unique embossed pattern is produced, with a distinct surface texture, increasing the product's three-dimensional effect and scratch resistance. Through the adjustment technology of ridges, shrinkage rate, and thickness distribution, the surface embossed layer is clear and precise, making it more wear-resistant than other products, preventing whitening at folds, reducing shrinkage, and ensuring uniform thickness distribution.

[0030] As a preferred embodiment, the inner sides of the folding-resistant textured groove and the scratch-resistant textured groove are provided with an adhesive layer 6, which is a hot melt pressure-sensitive adhesive.

[0031] As a preferred embodiment, the thickness of the polyvinyl chloride film 1 is between 0.5 and 1 mm.

[0032] As a preferred embodiment, the thickness of both the fold-resistant layer and the scratch-resistant layer is between 0.25 and 0.3 mm.

[0033] As a preferred embodiment, the depth of both the flexural texture groove and the scratch-resistant texture groove is between 0.05 and 0.1 mm.
