Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a writable film, and, for example, to a film suitable for protecting a delivery slip attached to a delivery parcel.

[Prior Art] Transparent resin films have been used for various purposes and uses.

For example, if the material itself is strong, it can be used as a packaging material because it can protect what is inside while allowing the interior to be seen through. For example, the top layer is overlaid to protect the delivery slip for parcels.
When a client attaches a written slip to a parcel, the surface of the slip is protected from rainwater.

[Problems to be Solved by the Invention] When writing on such a delivery slip, the film is once turned over to expose the writing surface. After writing, the release paper attached to the back of the film is peeled off and the film is attached directly to the outside of the parcel so that the slip can be read through the film.

However, writing on the slip requires flipping over the film, which is cumbersome, and conversely, if the film is not used, the slip cannot be protected, leading to misdelivery or loss.
This results in a loss of customer trust.

SUMMARY OF THE INVENTION Therefore, the present invention aims to solve the conventional drawbacks by not only protecting slips using a transparent resin film but also making it possible to write directly on the film.

That is, the present invention allows for writing to be performed directly on the protective film that is superimposed on the slip, and furthermore, the description can be written on the water friction resistance against rainwater etc.,
To provide a writable film which has sufficient abrasion resistance and scratch resistance and is free from staining.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a transparent writing layer having a fine writable uneven surface on the surface of a transparent synthetic resin film base material. It is characterized by being formed by coating.

[Function] According to the technical means of the present invention, it is sufficient to attach the writing layer to an appropriate object surface with the upper surface side, and write necessary information on the surface of the writing layer using a prescribed writing instrument.

The writing layer that is written with the writing instrument has a finely uneven surface that allows writing, so that the writing material from the writing instrument penetrates in the form of a drawing and is integrated with the writing layer, so that the writing is retained as it is. Ru.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 shown in the figure is a film base material made of a transparent synthetic resin film, and has a wall thickness sufficient to protect an object 4 to be pasted.

On the surface of this film base material 1, a writing layer 2 on which writing is possible is formed by coating. The writing layer 2 is formed of varnish and is applied to the surface of the film base material 1 by gravure printing, flexographic printing, or other printing means.Although it is solidified after application, it is transparent in itself, and is transparent to the film base material. The flexibility of material 1 is not impaired.

Therefore, the writing layer 2 itself consists of 70% resin, 4% matting agent, 4% dispersion aid, and 20% solvent.
, others have a component ratio of 2%, and fine irregularities are formed on the surface of the writing layer 2 after coating and solidification.

The finely uneven surface of the writing 112 is such that oil-based ink from a ballpoint pen, water-based ink from a pencil, lead from a pencil, ink from an ink pen, and writing materials from other writing instruments penetrate into the writing layer 2 and become integrated with the writing layer 2. It has become.

Further, an adhesive layer 3 is applied to the back surface of the film base material 1, so that it can be directly bonded to an appropriate object 4 to be pasted. Note that a release paper (not shown) is usually attached to the adhesive layer 3 to protect the adhesive layer 3.

The object to be pasted 4 is, for example, a delivery slip made up of a plurality of sheets that can be copied using pen pressure. It is designed so that it can be attached to parcels etc.

[Effects of the Invention] As described above, in the present invention, since the transparent writing layer 2 having a fine writable uneven surface is formed by coating on the surface of the transparent synthetic resin film base material 1, an appropriate covering can be applied. By pasting it on the 4 surfaces of the object, it not only protects the object 4, but also protects the object 4.
By writing the necessary information on the surface of writing layer 2 with a writing instrument,
Various information can be written directly.

When writing, the pressure of the pen is also applied below the film base 1, so for example, by placing a photocopy slip or the like below the film base 1, necessary information on a delivery parcel can be easily and quickly entered. Furthermore, the description provides sufficient water friction resistance, friction resistance, and scratch resistance against rainwater and the like, and there is no risk of staining.

Naturally, the film of the present invention can be applied not only to delivery slips, but also to various other items as long as it protects the object 4 to be pasted and requires shorthand writing, and is extremely versatile. Further, since the writing layer 2 itself is transparent, the writing layer 2 does not make it impossible to see through the film base 1 downward, and necessary entries corresponding to the object 4 to be pasted can be written without omission.
