る紙フィルム複合体に関する。Detailed Description of the Invention [Industrial Application Field] The present invention relates to a paper film composite of a stretched composite film and paper, particularly a polypropylene (hereinafter referred to as PP) film and a polyvinylidene chloride (hereinafter referred to as PvDC) film. The present invention relates to a paper film composite used for archival stationery, in which paper is laminated to a stretched composite film.
［従来の技術］
従来、写真用のポケットアルバム、名刺入れ、切手入れ

なる保存用文具には、フィルムとして塩化ビニルフィル
ムが用いられることが多い。[Prior Art] Conventionally, vinyl chloride film has often been used as a film for storage stationery consisting of a film and a mount, which are used for a relatively long period of time, such as pocket albums for photographs, business card holders, and stamp holders.

ニルフィルム内に写真を収納して保存している。For example, a pocket album for photos is made by partially bonding paper and vinyl chloride film using an ethylene-vinyl acetate adhesive, etc., and the photos are stored inside the vinyl chloride film that is formed into a bag shape on a mount. I have saved it.

より、更に安価なポケットアルバム用フィルムとして、
延伸ｐｐフィルムも一部に用いられている。The reason why vinyl chloride film is used is that it is transparent, has good adhesion to the mount (initial adhesion, permanent adhesion), does not change color, and does not cause blocking with photos. This is because the cost is low among films that satisfy these necessary physical properties. Also, as a pocket album film that is cheaper than vinyl chloride film,
Stretched PP films are also used in some cases.

で、限られている。[Problems to be solved by the invention] However, since there is no adhesive for the stretched PP film for adhesion to the mount, an adhesive is used, which has low creep strength and causes problems with peeling from the paper. Their use is limited, mainly as disposable, low-quality, inexpensive pocket albums.
このため、本発明者等は、接着剤と親和性のある樹脂を

めた。For this reason, the present inventors investigated a stretched PP film whose surface was coated with a resin that has an affinity for adhesives, and found that PVOC was suitable as the resin from the viewpoint of initial adhesion.

文具には使用できなかった。However, the so-called PVDC-coated stretched PP film, which is a generally known stretched PP film coated with PVDC,
Usually, the coating amount of PVDC is 39/g or more because the purpose is to provide gas barrier properties or heat sealing properties against oxygen and the like. The disadvantage of this composite film is that it discolors over time, so it cannot be used for long-term archival stationery such as pocket albums.
また、一般に延伸ｐｐフィルムにＰＶＤＣを塗工すると

いう問題点もあった。In addition, generally, coating PVDC on stretched PP film increases the number of steps, resulting in high costs.
There was also the problem that the advantage of using film was lost.

った。[Means for Solving the Problems] The present inventors have developed a paper film composite for use in archival stationery in which a stretched PP film is coated with PVDC.
As a result of various studies on the initial adhesion and permanent adhesion of VDC, blocking with stored items such as photographs, discoloration of photographs, and discoloration of the PVDC film itself, we found that by making the PVDC film layer Fi thinner than conventional ones, The inventors have found that the above-mentioned problems can be solved, and have completed the present invention.

The thinner the thickness, the better, but if it is less than 0.05 μm, the PV in the stretching process
Film cracking occurs in the DC coating layer, and uncoated areas are formed.
There is a risk that the initial adhesive strength will decrease. Also, 0.5 μm

発明では得られる延伸後の薄層フィルムが０．５μｍ以
下という極薄フィルムである点で特徴がある。There are two types of PVDC: water-based (emulsion-based) and solvent-soluble PVDC, but in both cases it is necessary to lower the concentration in order to reduce the amount of coating required. Water-based systems have the disadvantage of not only having problems with wettability, but also causing the painted surface to become rough and spoiling the appearance. Solvent-based systems have the advantage of reducing the amount of coating applied compared to water-based systems; Because problems are likely to occur in the engineering department,
It is extremely difficult to apply uniformly with a coating amount of 0.59/rd or less. Therefore, on the stretched pp rough file surface, P
As a result of intensive studies on the method of forming an ultra-thin VDC film, we found that a PvDC film obtained by on-machine coating of PVDC during the film manufacturing process satisfies the ultra-thin thickness of 0.5 μm or less according to the present invention, and is effective in terms of production and cost. They have found that it is the most suitable in terms of physical properties, has good film ductility, produces a uniform film with a good appearance after stretching, and does not discolor due to long-term use. On-machine coating of PVDC is usually done by melt-extruding the resin that becomes the base film and longitudinally stretching it, then on-machine coating PvDC on the stretched film, stretching it laterally, and creating a biaxially stretched composite film coated with PVDC. is obtained. On-machine coating of PVDC is a conventionally known method, but the present invention is characterized in that the thin film obtained after stretching is an extremely thin film of 0.5 μm or less.
ＰＶＤＣのオンマシンコーティングは、工程を増やさず
、薬品費も、基材フィルム単体よりほとんどアップしな
いという利点がある。PVDC on-machine coating has the advantage of not increasing the number of steps and requiring almost no increase in chemical costs compared to the base film alone.

要とする酸素など高度のガスバリア性を要求しないので
、使用するＰＶＤＣ樹脂の成分は特に限定されない。Since the PVDC used in the PVDC film of the present invention does not require the normally required high gas barrier properties such as oxygen, the components of the PVDC resin used are not particularly limited.

A pvoc coating liquid adjusted to a concentration of 20% was applied to the surface so that the solid content coating port was 19/1d. Then, it was immediately stretched horizontally to an effective magnification of 9 times to a thickness of 0.1 μm.
A biaxially stretched PP composite film (Example 1) having a PVDCI layer of Thereafter, the PvDCM layer films shown in the table were laminated in the same manner as in Example 1 to obtain biaxially stretched E)l) films (Examples 2 to 4). FIG. 1 is a perspective view showing an example of a paper film composite used in the storage stationery of the present invention. The 2nd side of the PVDC film of the stretched PP film 1 on which the obtained PVDC was laminated was coated with a separately prepared paper 3, i.e. 1209/7d high-quality paper, and a vinyl chloride emulsion (trade name: Vinyblanc, manufactured by Shin Kagaku 8) was applied as an adhesive 4. ) to 2
The adhesive surface partially coated with 0 g/Td (solid content 10 g/m) is immediately pressed with a pressure of 1 kg/d to obtain a photo pocket album having a storage section 5 formed between the partially coated sections 4 on three sides. Ta. FIG. 2 is a sectional view taken along line A--A in FIG. 1. For comparison, a polyvinyl chloride film with a thickness of 30 μm (control example), a normal PVDC coated stretched PP film (a biaxially stretched PP film with PVDC coated to a thickness of 3 μm, Alphan CN-01 manufactured by Honshu Paper Industries) (Conventional Example) and a corona-treated biaxially stretched PP film (Comparative Example 3) were used to create a pocket album in the same manner as in the Example. The adhesive used to bond the high-quality paper was an ethylene/vinyl acetate emulsion for the polyvinyl chloride film, and PvDC.
The coated stretched PP film uses vinyl chloride emulsion adhesive, and the corona-treated biaxially stretched PP film uses ethylene/vinyl chloride emulsion adhesive.
Vinyl acetate emulsions were used in each case. Color and monochrome photos were inserted into the pocket albums obtained in the above examples and comparative examples, and the temperature was 40°C and 70%RH.
We investigated the change in power over time. These results are shown in the table.
