Description

A velvet touch film

technical field

The utility model relates to the technical field of printing film, in particular to a velvet touch film.

Background technique

Usually, it is often necessary to mount a transparent film on objects such as paper products. Specifically, for parts that are easy to wear, such as the cover in the printing of the product manual and the outer surface of the carton, if a protective film is required, it must be printed after printing. Laminate it before folding and cutting, the film must be clear, tough, even texture, no blisters, flat surface, it's usually made of polypropylene, it's pre-coated with thermoplastic The polymer adhesive is used to combine with the paper, and the printing factory uses a hot roller to stick it firmly on the paper. The result is a paper with a better gloss finish, a thicker texture, and the colors printed on it are protected.

The surface of ordinary plastic film is relatively hard and very smooth, so it gives people a very stiff touch; and it is not wear-resistant, which can easily cause scratches on the film and even damage the surface of paper products and other objects.

Utility model content

In view of the deficiencies in the prior art, the purpose of the utility model is to provide a velvet tactile film, which has the advantages of strong wear resistance and scratch resistance, and a soft and delicate surface.

In order to achieve the above object, the utility model provides the following technical solutions:

A velvet tactile film, comprising a PTFE layer, a BOPP layer, an ink layer and a base layer for adhesion to objects arranged sequentially from outside to inside.

With the above technical solution, the surface of the PTFE layer is smooth, so that there is a smooth and delicate feel after touching, the comfort of silk and a strong velvet touch, and it also has chemical resistance, large air permeability, flame retardancy, high temperature resistance, and strong acid resistance. Alkali, non-toxic and other properties, so the PTFE layer is placed on the outermost layer, which not only improves the smoothness of the surface, but also has the characteristics of anti-wear, corrosion resistance and reducing the probability of fire; the BOPP layer has the advantages of high light transmittance and high barrier , so as to block the water vapor passing through the PTFE layer; the ink layer is located between the PTFE layer and the base layer, and the high barrier property of the BOPP layer prevents the ink from extending to the PTFE layer, improving the overall cleanliness; using the base The adhesiveness of the layers binds the whole to the object, thus achieving a stable connection.

Further, the base layer includes a PET layer and a PVC layer, and the PET layer is arranged between the ink layer and the PVC layer.

Using the above technical scheme, the PVC layer is attached to the surface of the object at the required temperature of the vacuum laminator, thereby realizing the effect of stable connection. At the same time, the PVC layer has the advantages of waterproof and antistatic, which reduces the influence of static electricity; the PET layer The toughness is the best among all thermoplastics, the tensile strength and impact strength are much higher than ordinary films, and the PET layer is set in the base layer to improve the overall stability.

Further, the PET layer includes a PET antistatic layer and a PET reflective layer, and the PET antistatic layer is located between the PET reflective layer and the PVC layer.

Using the above technical scheme, the PET layer is set as a PET antistatic layer and a PET reflective layer, and the PET antistatic layer is used to further improve the overall antistatic property; the PET reflective layer has excellent optical properties, and the PET reflective layer is arranged on the ink layer below, thereby improving overall clarity.

Further, an anti-ultraviolet coating is provided between the BOPP layer and the ink layer.

By adopting the above technical scheme, the anti-ultraviolet coating has high transparency and good adhesion. Visible light has a high transmittance to the anti-ultraviolet coating, and the anti-ultraviolet coating can effectively prevent the radiation, aging and leg color of strong ultraviolet rays on articles and ink layers, and has good adhesion and surface hardness.

Further, the thickness ratio of the PTFE layer, the BOPP layer, the ink layer and the base layer is 2:6:1:8.

Using the above technical solution, the thickness ratio of the PTFE layer, BOPP layer, ink layer and base layer is 2:6:1:8, so as to improve the overall flexibility and stability.

Further, the ink layer is set as environment-friendly water-based ink.

By adopting the above technical scheme, the environment-friendly performance is improved by setting the environment-friendly water-based ink.

Compared with the prior art, the utility model has the advantages of laminating the PTFE layer, BOPP layer, ink layer, PET layer and PVC layer sequentially, thus having the advantages of high light transmittance, smooth surface and wear resistance.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

A kind of velvet tactile film, as shown in Figure 1, comprises PTFE layer 1, BOPP layer 2, ink layer 4 and base layer 5 successively from outside to inside, PTFE layer 1 has the advantage of smooth surface, thus a kind of smoothness after touching Delicate hand feeling, while PTFE layer 1 has the advantages of wear resistance, corrosion resistance and flame retardancy, thereby reducing damage to objects to a certain extent; the thickness ratio of PTFE layer, BOPP layer, ink layer and base layer is 2:6 : 1:8 (the specific ratio is not shown in the figure), so as to improve the overall flexibility.

The PTFE layer 1 and the BOPP layer 2 are bonded together, so that the water vapor flowing from the PTFE is blocked from the outside of the ink layer 4 under the high barrier property of the BOPP layer 2; patterns are printed on the BOPP layer 2, thereby improving the overall performance. aesthetics.

An anti-ultraviolet coating 3 is adhered between the ink layer 4 and the BOPP layer 2, and the anti-ultraviolet coating 3 is composed of water-based nano-zinc oxide slurry or oily nano-zinc oxide slurry, polyurethane resin and coating additives, thereby avoiding the impact of ultraviolet rays on The ink layer 4 and the aging and fading caused by the radiation of the object; the ink layer is set as an environment-friendly water-based ink, thus having the advantage of environmental protection.

The base layer 5 sequentially includes a PET reflective layer 511, a PET antistatic layer 512 and a PVC layer 52 from outside to inside, and the ink layer 4 is arranged between the PET reflective layer 511 and the anti-ultraviolet coating 3, thereby protecting the ink layer 4 function and light concentrating; at the same time, the PET reflective layer 511 and the PET antistatic layer 512 increase the overall strength.

The PET antistatic layer 512 is adhered to the PVC layer 52 to reduce the damage caused by static electricity, and at the same time, the adhesion of the PVC layer 52 is used to achieve a stable overall connection to the object.

The specific implementation method of this embodiment: PTFE layer 1, BOPP layer 2, UV protection coating 3, ink layer 4, PET reflective layer 511, PET antistatic layer 512 and PVC layer 52 are adhered successively so that the tactile film has a surface The advantages of smooth, wear-resistant, corrosion-resistant, flame-retardant, UV-resistant, and anti-static.

When the tactile film needs to be installed, the PVC layer 52 is facing the surface of the object, and the PVC layer 52 is attached to the surface of the object at the required temperature by the vacuum laminating machine, thereby achieving the effect of stable connection.
