ートから作られた防虫性の穀類・生鮮食品用包装袋に関
する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an insect repellent cereal / fresh made from a film or sheet formed from a polyolefin composition containing an organic compound which is one component of a natural product. The present invention relates to a food packaging bag.
ポリオレフィン樹脂は、機械的性質、化学的性質、衛
生性等において優れているために、包装用、産業用、農
業用など幅広く利用されている。特に穀類などの包装分
野においては、防虫効果のある包装容器或いは袋の要求
が近年高まりつつある。Polyolefin resins are widely used for packaging, industrial use, agricultural use, etc. because of their excellent mechanical properties, chemical properties, hygiene properties and the like. In particular, in the field of packaging of cereals and the like, the demand for packaging containers or bags having an insect repellent effect has been increasing in recent years.

〜700nmの範囲で光線透過律を調整することが必要であ
る。このことは、包装材料の大きな要件である透明性が
犠牲にならざるを得ない。さらに、この方法は一般的に
即効性の点で難があることは否めない。The insect repellent effect of the use of light quality is based on the application of the insect's tropophilic reaction. Basic. Also,
Some types of pests respond more strongly to visible light than near-ultraviolet rays.
It is necessary to adjust the light transmission rule in the range of ~ 700 nm. This has to sacrifice transparency, a major requirement for packaging materials. Furthermore, this method cannot be denied a problem in general in terms of immediate effect.
これに対して、有機化合物を包装材に含有させる方法
及び防虫剤を包装袋に内包させる方法等については、即
効性という点では優れているが、人体に有害であった

あることからその使用範囲に限界がある。特に、食品関
係においては、その普及率が小さい。On the other hand, the method of including an organic compound in a packaging material and the method of including an insect repellent in a packaging bag are excellent in terms of immediate effect, but are harmful to the human body and have an odor which is not harmful to the package. And the range of use is limited due to its unpleasant appearance. In particular, the spread rate of food is small.
従って、無臭であり且つ人体に対して安全であって害
虫を寄せつけない効果を持つ物質があれば、食品関係を
初めとしてその利用価値は大きく開けてくる。Therefore, if there is a substance that is odorless, is safe for the human body, and has an effect of repelling pests, its utility value will be greatly increased, especially in the food industry.
