For example, the traditional surface decoration technology can be applied to notebook computers, smart phones, Portable multifunctional digital multimedia players, language translators, vehicles or home appliances, etc.

In addition, with the rise of environmental awareness in recent years, spraying or painting involves volatile organic compounds (VOC), and the implementation of traditional surface decoration techniques may be restricted by existing laws and regulations.

Although the products decorated by traditional surface decoration technology can bring convenience to people, the shell of this kind of product can be divided into metal shell or plastic shell. The appearance of the shell is relatively monotonous, so manufacturers will further use film or Paste film method to improve the appearance of the shell.

The film used for the above-mentioned coating or sticking film is designed to meet the needs of consumers and adopts a multi-layer design. Each layer has its own function, such as an antibacterial layer, a printing layer, an antenna layer, a metal layer, a hardened layer or a heat dissipation layer. However, the multi-layer design of the film will invisibly cause material waste and cost increase, so how to achieve the effect of the existing film with a smaller number of layers of film, so as to achieve cost reduction and material saving has become a matter for manufacturers to discuss project.

In view of the above shortcomings, the purpose of this creation is to provide a film that uses a combination of a carrier layer with a release effect and a universal functional layer with universal functions, so as to save materials and achieve the effect of reducing costs.

In order to achieve the above-mentioned purpose, the technical means of this creation is to provide a film body, which includes: a carrier layer; and a universal functional layer, which is arranged on one side of the carrier layer.

In one embodiment, a mask of the carrier layer has a first texture, and the universal function layer has a second texture for a mask of the first texture; when the universal function layer is disposed on the carrier layer, the first texture When the first texture is the side of the first texture, the universal function layer is transferred to the first texture to form the second texture.

In one embodiment, the carrier layer is a transparent layer or a translucent layer, and the carrier layer is a material with a release force; or the universal function layer is a soft material or a hard material. The universal functional layer is a single functional layer or a composite functional layer.

In summary, the universal functional layer of this creation has the multi-layer effect or the single-layer effect of the existing membrane body, so this creation can save a lot of materials during production, thereby achieving the effect of reducing costs.

The universal function layer 11 is disposed on the side of the carrier layer 10 having the first texture 100, and the universal function layer 11 has a second texture 110 relative to the first texture 100. The second texture 110 is a texture with a polyurethane (PU) effect. The universal functional layer 11 can be a single functional layer or a composite functional layer.

When the carrier layer 10 is a semi-transparent layer, it has the characteristic of accumulating energy. Therefore, when the universal functional layer 11 is an ultraviolet (Ultraviolet, UV) hardened resin layer, the carrier layer 10 that accumulates energy can be used as a universal functional layer. 11 Hardening. If discussed further, the translucent layer is formed by combining a transparent layer with a pigment, and the color of the pigment can be the natural color of the carrier material, or a translucent color created by adding other color masterbatch, such as translucent black and translucent blue. The semi-permeable black layer is used to gather energy and has the effect of stable control.

As mentioned above, the second texture 110 is formed in such a way that when the universal functional layer 11 is provided on the side of the carrier layer 10 with the first texture 100, the first texture 100 is the universal functional layer 11 of transfer printing facing the first texture 100 to form a second texture 110.

The single functional layer is a printing layer, a hardening layer, an adhesive layer, an antibacterial layer, a heat dissipation layer or a metal layer. For example, the single functional layer can be a polyurethane layer or a purple External light hardening resin layer, or polyurethane layer combined with metal materials, pigments, dyes, paper, leather, plasticizing additives or wood.

The composite functional layer is a combination of an adhesive layer and a hardened layer; or a combination of an adhesive layer, a hardened layer and a printing layer; or a combination of an adhesive layer, a hardened layer and an antibacterial layer; or a adhesive layer, a A combination of a hardened layer and a heat dissipation layer; or a combination of a bonding layer, a hardening layer and a metal layer; or at least one of a printing layer, a hardening layer, a bonding layer, an antibacterial layer, a heat dissipation layer, and a metal layer layer.

Wherein, the preparation methods of the printing layer, the hardening layer, the adhesive layer, the antibacterial layer, the heat dissipation layer, and the metal layer are all conventional methods known in the prior art, so they will not be repeated here.

The universal functional layer 11 can be a soft material or a hard material, the soft material is polyurethane, and the hard material is an ultraviolet curable resin; or the side of the universal functional layer 11 opposite to the carrier layer 10 is a bright surface; or Layer 10 has a bright side.

The hardened layer has a metal additive, a plasticizing additive, a pigment additive, a wood additive, a leather additive, a paper additive, or at least one of the foregoing.

Or the adhesive layer has a metal additive, a plasticizing additive, a pigment additive, a wood additive, a leather additive, a paper additive or at least one of the foregoing.

Or the universal functional layer 11 has a metal additive, a plasticizing additive, a pigment additive, a wood additive, a leather additive, a paper additive, or at least one of the foregoing.
