【発明の詳細な説明】
本発明は、貯蔵中の穀類に害虫が発生することを防止し
得る包装材料に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging material that can prevent pests from infesting grains during storage.
穀類、特にコメには貯蔵中コクゾウなどの食害を受ける
ことが良く知られている。これらの害虫は収穫時の原末

とのえば卵から幼虫へ郷化し、やがて成虫となって繁殖
する。従って原末には必ずこれら害虫の卵が産みつけら
れており、成育に通した環境になれば原末やそれを加工
した精米にはこれら害虫が発生する。It is well known that grains, especially rice, are susceptible to damage from insects such as brown elephants during storage. These pests lay their eggs on the raw powder at the time of harvest, and if conditions such as light, temperature, and humidity are right during storage, the eggs transform into larvae, and eventually become adults and reproduce. Therefore, the eggs of these pests are always laid in the powder, and if the environment is conducive to growth, these pests will appear in the powder and the milled rice processed from it.
穀類、特に精米の包装材料として、ポリエチレン等の光

は冷蔵庫を備え、プラスチック袋に入った穀類を常時冷
蔵庫に貯蔵している。紙袋等の光を透過しない容器を使
用すれば、ポリエチレンフィルム製の袋に比べて常温で
貯蔵しても害虫は発生しにくいが、包装を破ることなく
中味を観察することができず、かつヒートシールにより
口を閉鎖することができない等の不便がある。Light-transparent plastic films such as polyethylene have come to be used as packaging materials for grains, especially polished rice. For example, this product is widely used as a packaging material for milled rice because it allows consumers to observe the contents without opening the bag. Even in grains packaged in such light-transmitting plastic film bags, pests such as the brown elephant will appear if the environment is suitable for growth as described above. For this reason, rice retailers are equipped with refrigerators and store grain in plastic bags at all times. If you use a container that does not transmit light, such as a paper bag, pests will be less likely to occur even when stored at room temperature compared to polyethylene film bags, but it will not be possible to observe the contents without tearing the package, and There are inconveniences such as the inability to close the mouth with a seal.
そこで本発明者らは、内容物を外部から観察することが
できるように光透過性であるが、光不透過性材料と同様
に害虫の成育条件において貯蔵しても害虫の発生を防止
し得る包装材料について探索したところ、真珠光沢顔料
を練り込んだポリエチタン等のプラスチックフィルムが
その目的に適うものであることを知った。Therefore, the present inventors developed a material that is light-transparent so that the contents can be observed from the outside, but which, like light-opaque materials, can prevent pest infestation even when stored in pest-prone conditions. After searching for packaging materials, they found that plastic films such as polyethitane with pearlescent pigments were suitable for this purpose.
それ故、本発明はチタンマイカ、塩基性炭酸鉛、塩化ビ
スマス等の真珠光沢顔料を０．１〜２０重量％練り込ん
だ少なくとも部分的に光透過性のプラスチックフィルム
よりなる穀類貯蔵用包装材料を提供する。Therefore, the present invention provides a packaging material for grain storage consisting of an at least partially light-transparent plastic film incorporating 0.1 to 20% by weight of a pearlescent pigment such as titanium mica, basic lead carbonate, or bismuth chloride. provide.
光の干渉現象によって真珠様光沢を発する顔料は、例え

ては、チタンマイカ、塩基性炭酸鉛、塩化ビスマス等が
知られているが、鱗片状のマイカ薄片の表面を微粒子酸
化チタンで被覆したチタンマイカ顔料が無毒性のため好
ましい。Pigments that produce pearl-like luster due to light interference phenomena are used, for example, in the production of artificial pearls. Titanium mica, basic lead carbonate, bismuth chloride, and the like are known as pearlescent pigments, but titanium mica pigments, which are made by coating the surface of scale-like mica flakes with fine particles of titanium oxide, are preferred because they are nontoxic.
フィルムを形成するプラスチック材料としては、本来透
明で、可撓性があるプラスチックであればよい。その例
としては、可塑化ポリ塩化ビニル、ポリエチレン、ポリ
プロピレン、ポリエステル等がある。ポリエチレンが特
に好ましい。The plastic material forming the film may be any plastic that is inherently transparent and flexible. Examples include plasticized polyvinyl chloride, polyethylene, polypropylene, polyester, etc. Polyethylene is particularly preferred.
真珠光沢顔料の配合量はあまり少ないと効果がなく、反
対にあまり多いとフィルムが不透明になるので、一般に
０．１〜２０重量％、特に１〜５重量％の範囲が適当で
ある。If the amount of the pearlescent pigment is too small, the effect will be ineffective, and if it is too large, the film will become opaque, so the appropriate amount is generally 0.1 to 20% by weight, particularly 1 to 5% by weight.
上記配合量はフィルムへ直接線り込む場合であるが、固
形骨中対応量の真珠光沢顔料を含む塗料を、真珠光沢顔

ができる。Although the above blending amount is for direct inking into the film, the purpose can also be achieved by applying a paint containing pearlescent pigment in an amount corresponding to that in solid bone to a film that does not contain pearlescent pigment.
本発明の包装材料は一般に袋に加工して用いられるが、
他の形でも用いることができる。The packaging material of the present invention is generally processed into bags and used,
Other forms can also be used.
また穀類とは、コメ、オオムギ、コムギ、ソバ、および
それらの粉類、豆類、コーヒー豆、コシヨウ等を含み、

虫や、ダニ等も対象になる。In addition, grains include rice, barley, wheat, buckwheat, and their flours, beans, coffee beans, koshiyo, etc.
Pests are not limited to beetles such as the black elephant, but also include insects belonging to the order Lepidoptera, mites, etc.
本発明の包装材料による害虫発生予防効果を確かめるた
め、以下の実験を行った。In order to confirm the effectiveness of the packaging material of the present invention in preventing pest outbreaks, the following experiment was conducted.
チタンマイカ顔料（帝国化工■製ＴＰ−６９０）を２重
量％練り込んだポリエチレン袋と、対照としてチタンマ
イカ顔料を含ま５ないポリエチレン袋とを用意した。A polyethylene bag kneaded with 2% by weight of titanium mica pigment (TP-690 manufactured by Teikoku Kako ■) and a polyethylene bag containing no titanium mica pigment as a control were prepared.
これらポリエチレン袋に、同時に精米機で精白した精米
を１０に＋ｒづつ充填し、ヒートシールした。These polyethylene bags were simultaneously filled with polished rice polished using a rice milling machine and heat-sealed.
テスト包装品および対照各５袋づつを、ランダムに明る
い室内に常温で保管した。試験は夏期に実施した。Five test bags and five control bags were randomly stored in a bright room at room temperature. The test was conducted during the summer.
１週間後袋を開封し、コクゾウおよびココクジラの成虫

チレン袋に包装した精米にはコクゾウおよびココクジラ
が多数認められた。After one week, the bags were opened and inspected with the naked eye for the appearance of adult black elephants and gray whales. Although no pests were observed in the milled rice stored in polyethylene bags containing titanium mica, In the polished rice packaged in the control polyethylene bag without the fertilization, large numbers of gray elephants and gray whales were observed.
さらに３ケ月後、チタンマイカを練り込んだ袋を開封し
たが、コクゾウおよびココクシうの成虫の発生は認めら
れなかった。After a further three months, the bag containing the titanium mica was opened, but no adult moths of K. kokusai or K. kokukushi were observed.
