Abstract

PROBLEM TO BE SOLVED: To prepare a pasted film which can be used as a covering film having excellent transparency, can also be used as a thin and tough heat-insulating film, hardly forms wrinkles when adhered, can easily be peeled, can easily be adhered, and is inexpensive. SOLUTION: This film with a paste is obtained by adhering the paste 21 to a synthetic resin film surface 11 to form many fine enclosures 20. When the synthetic resin surface 11 is adhered to an opposite article surface 41, an intercepted air layer 30 can be formed between the paste enclosures 20 and the article surface 41. When the synthetic resin film 10 is cut in response to the size of the article surface 41, the cut paste enclosures 20B has an adhesion distance between the paste 21 and the paste 21 in a range hardly permitting the release of the adhesion of the article surface 41.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glued film in which a surface of a synthetic resin film is glued.

[0002]

2. Description of the Related Art In a conventional glued film, glue is applied over the entire surface of a synthetic resin film, or
Many small point-like pastes were applied on the entire surface so as to be scattered. The former is firmly adhered once adhered to the surface of the article when it is adhered to the surface of the article.However, on the other hand, it has drawbacks such as easy wrinkling at the time of attachment and difficulty in reattaching. There is an advantage that it is difficult to wrinkle when wearing, it is easy to peel off and re-attach, but when you want to use both the former and the latter as a heat insulating film, there are cases where it is formed on a metallized film and a case where a foam film is used, The former has the disadvantage that it is easy to secure transparency, but has the disadvantage of being expensive.
In addition to its extremely poor transparency, it has a disadvantage that it is thick and extremely fragile when made extremely thin.

[0003]

SUMMARY OF THE INVENTION The present invention provides a glued film which can be used as a highly transparent coated film and which can be used as a thin and tough heat insulating film. Another object of the present invention is to provide a glued film that is less likely to be wrinkled at the time of sticking, is easily peeled off, and is easily re-attached. Further, the present invention provides a glued film which can be easily mass-produced and which can be produced at low cost.

[0004]

In order to achieve the above-mentioned object, the glued film of the present invention is formed by adhering a glue 21 to a synthetic resin film surface 11 to form a large number of fine glue enclosures 20 as shown in the drawing. When the synthetic resin film surface 11 is adhered to the opposing article surface 41, the adhesive
When the synthetic resin film 10 is cut in accordance with the size of the article surface 41, the cut-off adhesive enclosure 20B is formed. However, the glue 21 has an adhesion interval between the glue 21 and the glue 21 in a range where the glue 21 is not easily peeled off from the article surface 41.

[0005] In the present invention, the synthetic resin film surface,
A large number of minute glue enclosures formed by glue adhesion can be formed by applying glue on the synthetic resin film surface in various lattice patterns or by applying glue on irregular pattern patterns. Also, there are those which are formed by applying a large number of glue lines so as to be separated from each other.These fine and large number of glue enclosures apply the glue to the synthetic resin film surface by a known printing method such as gravure or flexo. It can be easily achieved by application. The adhesive or coating interval between the glue forming the glue enclosure and the glue is about 3 mm or less, and when the synthetic resin film is cut in accordance with the size of the article surface, the cut glue enclosure is attached to the adhered article. It is preferable as a range that is difficult to peel off from the surface. Further, in addition to the above-mentioned glue-to-glue adhesion interval, the glue or glue line has a glue width of about 1 mm or less and a glue thickness of about 0.2 mm or less. It is preferable from the viewpoint of easy peeling and reattaching. In the present invention, when it is necessary to peel the synthetic resin film from the surface of the article in the future, a known adhesive that can be peeled off is used as the glue. In this case, a water-soluble adhesive may be particularly preferable.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention is shown in FIGS. Reference numeral 10 denotes a known thin synthetic resin film such as a polyethylene terephthalate film, a polypropylene film, and a polyvinyl chloride film. 2
1 is a linear glue attached to the synthetic resin film surface 11,
It is made of known adhesives such as acrylic, butyl rubber, polyisobutylene, etc. having low weather resistance, low adhesiveness, non-staining property, and no adhesive residue, and is suitable for adhesion on glass surfaces and the like. The linear glue 21 has a large number of glue enclosures 2 formed by a lattice pattern.
0 is formed. In the case of this example, the glue enclosure 20 has a linear glue width of about 0.5 mm, a thickness of about 0.2 mm, and a glue interval S1 or S2 of about 2 mm. Therefore, if the product of the present invention is cut in accordance with the size of the window glass surface 41 and is adhered to the window glass surface 41, a large number of glue enclosures 20 adhere to the window glass surface 41 as shown in FIG. Air layer 3 blocked between windowpane surface 41 and glue enclosure 20
0 is formed to perform an adiabatic action. Synthetic resin film 10
If the transparency of the glue 21 is large, the transparency of the window glass 40 is not hindered. In winter, the indoor heat is hardly radiated to the outside through the window glass 40 in winter, and
In summer, solar heat is rarely cut off to raise indoor temperature. When the product of the present invention is cut C, the adhesion interval S1 or S2 between the glue 21 and the glue 21 of the cut glue enclosure 20B.
Is small, the cutting of the adhesive enclosure 20B of the synthetic resin film 10 does not largely separate from the window glass surface 41.
In addition, since the glue 21 of the glue enclosure 20 can be applied to the synthetic resin film surface 21 at minute intervals as a fine linear glue, when the product of the present invention is stuck to the article surface 41, it does not easily wrinkle. It is easy to peel off and reattach.

[0007]

As described above, the product of the present invention can be easily applied to window glass of buildings and automobiles, frozen / refrigerated showcases, etc., easily peeled off, and has high transparency (in the case of colored transparent and large light transmittance) It has the advantage that it can be easily and easily used as a heat-insulating coated film having a high metal (including the case of metal deposition) and is extremely inexpensive.
