Description
本発明者らは鋭意研究の結果、特定の塗布剤を使用することによりかかる課題が解決できることを見いだし、本発明を完成するに至った。
すなわち本発明は、基紙の表面に、天然ゴム及びエチレン−酢酸ビニル系共重合樹脂を主成分とし、天然ゴム含有量が固形分換算で２０〜４５重量％であるエマルジョン１００乾燥重量部に対して、無機系填料を１０〜５０重量部の割合で含む塗布剤を、固形分として１〜２０ｇ／ｍ２塗布した滅菌紙、を提供するものである。
As a result of intensive studies, the present inventors have found that such a problem can be solved by using a specific coating agent, and have completed the present invention.
That is, the present invention, the surface of the base paper, natural rubber及 beauty ethylene - vinyl acetate copolymer resin as the main component, the emulsion 100 parts by dry weight of natural rubber content of 20 to 45% by weight in terms of solid content On the other hand, a sterilized paper coated with 1 to 20 g / m 2 of a solid coating containing a coating agent containing 10 to 50 parts by weight of an inorganic filler is provided.
本発明で用いられる天然ゴム及びエチレン−酢酸ビニル系共重合樹脂を主成分としたエマルジョンは、天然ゴム含有量が固形分換算で２０〜４５重量％のものが好適である。エマルジョン中の天然ゴム含有量が２０重量％未満ではピール性が十分に得られず、４５重量％を超えるとシール強度が低下する。かかる天然ゴム及びエチレン−酢酸ビニル系共重合樹脂を主成分としたエマルジョンを作製するには、天然ゴムラテックス、エチレン−酢酸ビニル系共重合樹脂エマルジョンそれぞれを塗布前に混合して用いても良いし、また予め天然ゴムとエチレン−酢酸ビニル系共重合樹脂の分散体を用いても良い。天然ゴムとエチレン−酢酸ビニル系共重合樹脂の分散体としては、例えば、東洋モートン社製ＡＤ−７１６、ムサシノケミカル社製コアテックスＨＭ−１００等を例示することができる。 Natural rubber及 beauty ethylene used in the present invention - emulsion the vinyl acetate copolymer resin as a main component are those amounts of natural rubber containing closed is 20 to 45 wt% in terms of solid content is preferable. Natural rubber containing chromatic amount is not sufficiently obtained peel properties is less than 20 wt% in the emulsion, the seal strength is lowered when exceeding 45 wt%. Such natural rubber及 beauty ethylene - To produce an emulsion composed mainly of vinyl acetate copolymer resin, natural rubber latex, ethylene - be used in the respective vinyl acetate copolymer resin emulsion was mixed before coating good to also advance the natural rubber and ethylene - may be used a dispersion of a vinyl acetate copolymer resin. Natural rubber and ethylene - The dispersion of vinyl acetate copolymer resin, for example, produced by Toyo Morton Co., Ltd., AD-716, can be exemplified Musashino Chemical Co. Coatex HM-100 and the like.
無機系填料の配合比は、天然ゴム及びエチレン−酢酸ビニル系共重合樹脂を主成分としたエマルジョン１００乾燥重量部に対し、１０〜５０重量部、好ましくは２０〜４５重量部添加される。無機系填料が１０重量部未満であると通気性が劣ったりシール痕が残り難くなり、５０重量部を越して用いると無機系填料が脱落したりヒートシール強度が低下したりする。 The compounding ratio of the inorganic filler include natural rubber及 beauty ethylene - to emulsion 100 parts by dry weight composed mainly of vinyl acetate copolymer resin, 10 to 50 parts by weight, preferably added from 20 to 45 parts by weight . If the inorganic filler is less than 10 parts by weight, the air permeability is poor or seal marks hardly remain, and if it exceeds 50 parts by weight, the inorganic filler falls off or the heat seal strength decreases.
実施例１

The base paper 1, natural rubber containing chromatic ethylene weight natural rubber containing closed is 41% by weight in terms of solid content - vinyl acetate copolymer resin emulsion (produced by Toyo Morton Co., Ltd., AD-716) 100 parts by dry weight of talc A coating liquid consisting of 43 parts by weight and 1 part by weight of a surfactant (manufactured by Nippon Emulsifier, New Coal TN-6618) was applied as a solid content at 8 g / m 2 to prepare a sterilized paper of the present invention.
The evaluation results of the obtained sterilized paper are shown in Table 1 together with other examples and comparative examples.
実施例４
実施例１において、天然ゴム含有量を固形分換算で３５重量％にかえるために、塗布液中の天然ゴム含有エチレン−酢酸ビニル系共重合樹脂エマルジョン添加量を１００乾燥重量部から８６乾燥重量部にかえ、エチレン−酢酸ビニル系共重合樹脂エマルジョン（東洋モートン社製ＡＤ３７Ｒ３４５Ｊ）を１４乾燥重量部加えた以外は実施例１と同様に実施し、本発明の滅菌紙を得た。
Example 4
In Example 1, in order to change the 35% by weight of natural rubber containing chromatic amount in terms of solid content, natural rubber containing chromatic ethylene in the coating liquid - vinyl acetate copolymer resin emulsion added amount from 100 parts by dry weight The sterilized paper of the present invention was obtained in the same manner as in Example 1 except that 14 dry parts by weight of an ethylene-vinyl acetate copolymer resin emulsion (AD37R345J manufactured by Toyo Morton Co., Ltd.) was added instead of 86 dry parts by weight.
実施例５
実施例４において、基紙１にかえて基紙２を用いた以外は実施例４と同様に実施し、本発明の滅菌紙を得た。

Comparative Example 3
In Example 4, in order to change the 18% by weight of natural rubber containing chromatic amount in terms of solid content, natural rubber containing chromatic ethylene in the coating liquid - vinyl acetate copolymer resin emulsion amount from 86 parts in dry weight The sterilized paper of the present invention was obtained in the same manner as in Example 4 except that the amount of the ethylene-vinyl acetate copolymer resin emulsion was changed from 14 to 60 dry parts by weight instead of 40 dry parts. It was.
