接触界面からイソチオシアン酸エステルが蒸気状で浸過
し、成形品中の吸着剤に吸着保持される。Next, a polymer molded article (hereinafter also simply referred to as a molded article) containing an adsorbent is brought into contact with an isothiocyanate ester in liquid or vapor form. Examples of the method of contacting the molded article with the isothiocyanate ester in vapor form include a method of holding the molded article in the vapor of the isothiocyanate ester or a gas containing the same, such as air or nitrogen. Through this contact treatment, the vapor of the isothiocyanate ester permeates into the molded article and is adsorbed and retained by the adsorbent in the molded article. Methods for contacting the molded product with the inthiocyanate ester in liquid form include spraying or coating the molded product with a liquid isothiocyanate ester or a solution thereof, or a method of contacting the molded product with a liquid isothiocyanate ester or its solution. Examples include a method of immersing a molded article in the solution. Even in such a treatment, the isothiocyanate ester permeates into the molded article from the contact interface in vapor form and is adsorbed and retained by the adsorbent in the molded article.

からはイソチオシアン酸エステルの蒸気が放散される。The molded product thus obtained has the property that the adsorbent present therein contains isothiocyanate ester and gradually releases the isothiocyanate ester, and the polymer constituting the molded product contains isothiocyanate. Since acid esters are permeable, vapor of the isothiocyanate ester is radiated from the surface of the molded article.

題となっている分野に有利に用いることができる。Further, when the molded article is a container, the outer surface thereof can be laminated or coated with a polymeric film that is substantially impermeable to isothiocyanate esters. In such a molded article, isothiocyanate ester is emitted from the side that is not coated with a film or coating. Examples of polymers that do not substantially allow isothiocyanate to pass through include polyester, polyamide, polyvinyl chloride, polyvinylidene chloride, etc. Isothiocyanate ester is released from its surface and has antibacterial properties by itself. Therefore 1

ことにより、食品の鮮度保持を行うことができる。In the molded article of the present invention, the sheet or film can be used as a packaging material for hermetically packaging foods and other articles where microorganisms are likely to multiply. In articles hermetically packaged with such packaging materials, the antibacterial action of the isothiocyanate ester released from the surface of the film or sheet prevents the growth of mold as well as the proliferation of other microorganisms. Also,
Container-shaped molded articles can also be used as anti-fungal and anti-bacterial containers. The thread-like molded product can be used as a mold-proof and antibacterial mesh bag for fruits, vegetables, etc. by making it into a bag. Since isothiocyanate ester is generated from the surface of the pellet-shaped molded article, it can be used as an isothiocyanate ester generator. These isothiocyanate ester generators can be packaged in isothiocyanate ester-permeable packaging materials such as paper or polyethylene or polypropylene, and the package is sealed together with the food in the packaging material to maintain the freshness of the food. It can be performed.
（実施例） 次に本発明を実施例によりさらに詳細に説明する。(Example) Next, the present invention will be explained in more detail with reference to Examples.
実施例
吸着剤（セピオライト微粉末）４０重斌部とポリエチレ
ン６０重麓部を溶融混合した後、フィルム状に成形して
吸着剤を含有する厚さ約５０−のフィルムを得、このフ
ィルムの一方の面にポリエステルフィルムを積層接着し
た。Example After 40 parts of adsorbent (sepiolite fine powder) and 60 parts of polyethylene were melt-mixed, they were formed into a film to obtain a film containing the adsorbent with a thickness of about 50 cm, and one side of this film was A polyester film was laminated and adhered to the surface.
次にこのフィルムを、液状のイソチオシアン酸エステル
イソチオシアン酸アリル）を入れたシャーレとともに密
閉性容器に入れて密封し、温度４０℃の恒温槽に入れ、
２４時間放置した後、容器を開放してフィルムを取り出
した。このフィルムはそのポリエチレンフィルム面のみ
から辛子臭を発し。Next, this film was placed in an airtight container together with a petri dish containing liquid isothiocyanate ester (allyl isothiocyanate), sealed, and placed in a constant temperature bath at a temperature of 40 ° C.
After standing for 24 hours, the container was opened and the film was taken out. This film emits a mustard odor only from the polyethylene film surface.
イソチオシアン酸エステルが放出されていることが確認
された。It was confirmed that isothiocyanate ester was released.
次に、このフィルムから袋体を形成し、その袋の開口部
から切もちを入れてその開口部をヒートシールにより封
止した。この包装物は、外面にイソチオシアン酸エステ

ＩＳされていることから。Next, a bag was formed from this film, a cutter was inserted through the opening of the bag, and the opening was sealed by heat sealing. This package has a polyester film on the outer surface that is substantially impermeable to isothiocyanate ester,
Because it is IS.
その外面からは辛子臭を発生しないものであった。No mustard odor was emitted from the outside.
また、比較のために、ポリエチレンの袋に同様に切もち
を入れてヒートシールにより密封した。For comparison, a cut mochi was similarly placed in a polyethylene bag and sealed by heat sealing.
前記した包装切もちを室温で放置したところ、比較用の
切もちは３日間でカビの発生が見られたのに対し、本発
明のフィルムで包装された切もちは、１力月を経過して
もカビの発生は認められなかった。When the above-mentioned packaged cut mochi was left at room temperature, mold growth was observed in the comparative cut mochi after 3 days, but mold growth was observed in the cut mochi wrapped in the film of the present invention after 1 month. However, no mold growth was observed.

ことが確認された。Example 2 A laminated adhesive film of a polyethylene film and a polyester film containing the adsorbent shown in Example 1 was soaked in a 10% alcohol solution of inthiocyanic acid ester.
After being immersed for a period of time, it was taken out and dried. This film also emitted a mustard odor only from the polyethylene film surface, and it was confirmed that inthiocyanate ester was released.
