There is a problem in that it increases the size of fruits and vegetables, accelerates the aging and discoloration of fruits and vegetables, and also promotes the blooming of flowers.
（課題を解決するための手Ｄ）
本発明者らば上記問題点を解決し、より優れた青果物・
切花の保存用フィルムを開発すべく研究を行った結果、
ゼオライトと高吸水性樹脂の両者を活用することによっ
て目的を達成できることを見出し本発明を完成した。(Mean D for Solving the Problem) The inventors of the present invention will solve the above problems and produce better fruits and vegetables.
As a result of research to develop a film for preserving cut flowers,
The present invention was completed by discovering that the object can be achieved by utilizing both zeolite and super absorbent resin.
すなわち、本発明はゼオライト及び高吸水性樹脂が塗布
されていることを特徴とする青果物・切花の鮮度保持用
フィルム又はシートを提供するものである。That is, the present invention provides a film or sheet for preserving the freshness of fruits, vegetables, and cut flowers, which is coated with zeolite and a super absorbent resin.
本発明フィルム又はシートは段ボールの内側にラミネー

ましい。As the superabsorbent resin used in the present invention, any superabsorbent resin that is generally used as a superabsorbent resin can be used. For example, highly water-absorbent polymers such as polyacrylic acid, starch-acrylate, vinyl acetate, and maleic acid copolymer are used. Particularly preferred is the body.

塗布することによって行うことができる。To produce the film or sheet of the present invention, a film or sheet in which zeolite and a superabsorbent resin are dispersed in a solvent such as alcohol, acetate, methyl edyl ketone, etc. is prepared using a gravure printing machine, an O-le coater, etc. This can be done by applying it.
この際ゼオライト及び高吸水性樹脂のフィルム、シート
への塗布をより良く行うためには、バインダーを入れる
ことが好ましい。At this time, in order to better coat the zeolite and superabsorbent resin onto the film or sheet, it is preferable to add a binder.
本発明のようにゼオライト及び高吸水性樹脂をフィルム
又はシートに塗布せずに、フィルム又はシート中に混練
することも考えられるが、該フィルム、シートの強度が
低下し、且つゼオライト及び高吸水性樹脂の作用効果も
劣るので好ましくない。Although it is possible to knead the zeolite and super absorbent resin into the film or sheet without applying them to the film or sheet as in the present invention, the strength of the film or sheet may decrease, and the zeolite and super absorbent resin may be kneaded into the film or sheet. This is not preferable because the effect of the resin is also inferior.
ゼオライトのフィルムへの塗布量としては１００ｍＦｌ
／尻以上必要でおり、それ以下にすると効果が劣るので
好ましくない。The amount of zeolite applied to the film is 100 mFl.
/ butt or more is required, and if it is less than that, the effect will be inferior, so it is not preferable.
高吸水性樹脂のフィルムへの塗布量としては５０〜２０
００１ｆｔｇ／Ｔｄの範囲が好ましく、５０ｍｙ／ｒｄ
以下にするとその効果に乏しく、２０００ｍｇ／７７（
以上にすると青果物・切花のしおれをかえって促進する
ので好ましくない。The amount of super absorbent resin applied to the film is 50 to 20
A range of 001 ftg/Td is preferable, and 50 my/rd
If it is less than 2000mg/77(
Exceeding this level is undesirable because it will actually accelerate the wilting of fruits, vegetables, and cut flowers.
本発明のフィルム又はシートが青果物・切花の鮮度保持
に有効なのは青果物・切花から発生するエチレンガスを
ゼオライトが吸着し、エチレンガスによる老化を防げる
とともに、青果物・切花から蒸散する水分を高吸水性樹
脂が吸水し、該包装体内の湿度をコントロールするとい
う２つの作用効果が相乗的に動くためと推定される。The reason why the film or sheet of the present invention is effective in maintaining the freshness of fruits, vegetables, and cut flowers is that zeolite adsorbs ethylene gas generated from fruits, vegetables, and cut flowers, and prevents aging due to ethylene gas. It is presumed that this is because the two effects of absorbing water and controlling the humidity inside the package work synergistically.
従って、ゼオライトと高吸水性樹脂の両者が塗布という
作用しやすい形で存在していることが重要なのであって
、ビオライ１〜だけでは先に水分を吸着してしまい、肝
心のエチレンガス吸着能が喪失するし、一方、高吸水性
樹脂だけではもともとエチレンガスの吸着能がなく、青
果物・切花の老化を防ぐことができないのである。Therefore, it is important that both zeolite and superabsorbent resin exist in a form where they can easily act as a coating, and Bioly 1~ alone will adsorb water first, reducing the essential ethylene gas adsorption ability. On the other hand, superabsorbent resins alone do not have the ability to adsorb ethylene gas and cannot prevent the aging of fruits, vegetables, and cut flowers.
