Description

Technical Field

[0001] This utility model relates to the field of plastic products technology, specifically to high-temperature resistant films. Background Technology

[0002] Cast film is a type of film produced in the plastics industry through a casting extrusion process.

[0003] In the existing technology of cast film, there are composite iridescent films, so that when the composite film is attached to the surface of the object after the iridescent film is composited, there is no need to attach an additional outer film to protect the iridescent film.

[0004] However, due to the poor heat resistance of the iridescent film itself, the temperature during processing such as hot pressing or high-temperature coating cannot exceed 80 degrees Celsius, otherwise it is easy to wrinkle, shrink or break directly.

[0005] To address the above problems, a high-temperature resistant cast film technology solution is proposed. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a high-temperature resistant film.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-temperature resistant film, comprising a main body, the main body comprising a holographic layer, a shaping layer and a protective layer being sequentially disposed on one side of the holographic layer, the molten protective layer flowing into and filling the accommodating cavity inside the protective layer through a plurality of connecting openings on the protective layer, and protrusions forming in the opposite direction to the main body of adjacent accommodating cavities.

[0008] The present invention is further configured such that the connecting port is located near the protrusion.

[0009] The present invention is further configured such that: the shaping layer is provided with a communication port on both sides opposite to the receiving cavity.

[0010] The present invention is further configured such that: the shaping layer includes two support films connected by heat sealing, a plurality of the contacting end faces of the two support films are in the same plane, and the plane is arranged parallel to the main body.

[0011] The present invention is further configured such that the protrusions on the shaping layer are distributed in an array.

[0012] The present invention is further configured such that a release layer is provided on the other side of the shaping layer of the main body.

[0013] In summary, the present invention has the following beneficial effects: the molten protective layer can flow into and fill the internal cavity of the protective layer through several connecting openings, thereby expanding the cavity and further improving the support effect of the shaping layer after the protective layer flows into the cavity, thereby achieving the effect of blocking heat and avoiding the phenomenon of wrinkling or shrinkage of the film due to excessively high pressing temperature.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] High-temperature resistant films, such as Figures 1 to 3 As shown, the film includes a main body 1, which includes a holographic layer 3. A shaping layer 5 and a protective layer 2 are sequentially disposed on one side of the holographic layer 3. A release layer 4 is disposed on the other side of the shaping layer 5. The release layer 4 can be separated from the film during use. The protective layer 2 is made of polyethylene material by casting. The melting point of the polyethylene film is related to its density. This application uses low-density polyethylene material to make the protective layer 2, which has a melting point of 85 degrees Celsius to 100 degrees Celsius. The protective layer 2 is also made of high-density polyethylene material.

[0020] When the film is coated with clothing and other items at high temperature, the molten protective layer 2 can flow into and fill the receiving cavity 52 inside the protective layer 2 through several connecting holes 6 opened on the protective layer 2, thereby expanding the receiving cavity 52. ​​After the protective layer 2 flows into the receiving cavity 52, it further improves the support effect of the shaping layer 5, thereby achieving the effect of blocking heat, thus avoiding the phenomenon of wrinkling or shrinkage of the film due to excessively high pressing temperature.

[0021] like Figures 1 to 3 As shown, the shaping layer 5 includes two support films 51 connected by heat sealing. Several contact end faces of the two support films 51 are in the same plane and the plane is parallel to the main body 1. Several protrusions on the shaping layer 5 are distributed in an array. Protrusions are formed in the opposite direction of the adjacent receiving cavity 52 towards the main body 1. The protrusion structure effectively improves the support effect of the shaping layer 5.

[0022] In order to increase the rate at which molten polyethylene material flows into the receiving cavity 52, the connecting port 6 is located near the protrusion, and the shaping layer 5 is provided with connecting ports 6 on both sides opposite to the receiving cavity 52.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
