【０００１】[0001]
本考案は、環境保全用発泡袋に関するもので、特にポリエチレンを主成分とす る発泡されてなるフイルムを包装用袋の材質とし、主にポリエチレン、炭酸カル シウム及び発泡剤の三者を適する比率で混合してなる環境保全用発泡袋に関する ものである。 The present invention relates to a foaming bag for environmental protection, and in particular, uses a foamed film mainly composed of polyethylene as a material of the packaging bag, and mainly uses polyethylene, calcium carbonate, and a foaming agent in a suitable ratio. It relates to a foamed bag for environmental preservation, which is mixed with the above.
【０００２】[0002]
一般のビニール袋に使用する成分は、単一原料（例としてポリ塩化ビニールＰ ＶＣ）からできている。 The components used in common plastic bags are made from a single material (eg, polyvinyl chloride PVC).
【０００３】[0003]
しかしながら、この種の環境保全用発泡袋には、その原料の材質及び燃焼させ たときに発生する問題として、次に述べる問題がある。 １．ビニール袋を焼却炉で、焼却すると、その成分が壁に粘着し、焼却炉の燃焼 効率を下げる。 ２．一般のビニール袋は、焼却後に滴状になり、その滴状物は高温の滴状残留物 となって延焼現象を起こす。 ３．一般のビニール袋は、焼却すると、環境を汚染する。 ４．一般のビニール袋は、袋上に直接書けない上、書いても簡単に消えてしまい 、実用的でない。そのため、上述の欠点を改善し、環境を保全し、実用性のある 環境保全用発泡袋を提供する。 However, this kind of foam bag for environmental protection has the following problems as problems that occur when the material is used and when it is burned. 1. When a plastic bag is incinerated in an incinerator, its components stick to the walls, reducing the combustion efficiency of the incinerator. 2. General plastic bags become droplets after incineration, and the droplets become hot droplets and cause the spread of fire. 3. General plastic bags pollute the environment when incinerated. 4. A general plastic bag cannot be written directly on the bag, and even if it is written, it easily disappears, making it impractical. Therefore, the above disadvantages are improved, the environment is preserved, and a practical foam bag for environmental conservation is provided.
【０００４】[0004]
上記課題を解決するため、本考案は上記の問題に鑑み、鋭意検討した結果、ビ ニールフィルムに代わって、オレフィン系材質を使用し、地球に大量に存在する 炭酸カルシウムを多く添加して発泡剤とを配合し、オレフィン系発泡フィルムを 得ることを見出し、本考案の環境保全用発泡袋に至った。 本考案の環境保全用発泡袋は、下記の点を特徴とするものである。 １．焼却炉で焼却後、炉内壁に粘着することなく、焼却炉の効率を下げない。 ２．焼却すると、粉末状になって、滴状化現象を起こさないため、安全性に優れ 、延焼現象を引き起こさない。 ３．ビニール袋の成分構成を改善して、表面に書け、印刷品質を向上させる。 このため、本考案は主にポリエチレンを主成分とする発泡された材質からなる ことを特徴とする。 In order to solve the above problems, the present invention has been intensively studied in view of the above problems, and as a result of using the olefinic material instead of the vinyl film, adding a large amount of calcium carbonate present in a large amount on the earth to a blowing agent. Was found to obtain an olefin-based foamed film, and led to the environmentally-friendly foamed bag of the present invention. The foam bag for environmental protection of the present invention is characterized by the following points. 1. After incineration, the incinerator does not lose its efficiency without sticking to the inner wall of the incinerator. 2. When incinerated, it turns into a powder and does not cause a dropping phenomenon, so it is excellent in safety and does not cause a fire spread phenomenon. 3. Improve the composition of plastic bags to write on the surface and improve print quality. For this reason, the present invention is characterized by being made of a foamed material mainly composed of polyethylene.
【０００５】 以下、本考案環境保全用発泡袋のポリエチレン発泡フィルムの製造を図面に基 づいて説明する。 先ず、図１が示すように、主にポリエチレン（ＰＥ）（５０％〜７０％）、炭 酸カルシウム（２０％〜３０％）及び発泡剤のアゾ化合物（ＡＺＯ）（ジメチル アシド）（０．１〜０．２％）を使用し、上述の三種類の原料を撹拌器Ａで混合 し、１５０℃〜２００℃の間に温度制御をしながら発泡機Ｂで加熱発泡を行う。 図２に示すように、結晶型のポリエチレン（ＰＥ）樹脂は、発泡時、その加工区 （成形加工可能域）は非常に狭いため、原料混合時、加工温度を１５０℃〜２０ ０℃に制御してブローイング成形を行い、製品Ｄを完成させる。Hereinafter, the production of the polyethylene foam film of the environmentally-friendly foam bag of the present invention will be described with reference to the drawings. First, as shown in FIG. 1, polyethylene (PE) (50% to 70%), calcium carbonate (20% to 30%), and an azo compound (AZO) (dimethyl acid) (0.1%) as a blowing agent were mainly used. The above three types of raw materials are mixed with a stirrer A and heated and foamed with a foaming machine B while controlling the temperature between 150 ° C and 200 ° C. As shown in FIG. 2, the processing temperature of the crystalline polyethylene (PE) resin is controlled to 150 ° C. to 200 ° C. when the raw materials are mixed because the processing zone (formable processing area) is very narrow during foaming. Then, blow molding is performed to complete the product D.
【０００６】 上述の製造工程に従う本考案の１実施例の成分比率及び条件は以下のとおりで ある。 ａ．ポリエチレン（ＰＥ） ６９．８％ ｂ．炭酸カルシウム（ＣａＣＯ３） ３０％ ｃ．発泡剤−アゾ化合物（ＡＺＯ）（ジメチルアシド）０．２％ ｄ．温度制御： １８０℃ 上述成分を図１に示す製造工程によって、ブローイング成形にて、発泡袋を製 造すると、その表面に鉛筆、ボールペンで簡単に書くことができる。また、この 環境保全用発泡袋は、焼却すると、粉末状になり、焼却炉内の壁に粘着したり、 延焼現象を起こすことがない。更に組成中に適当な比率の光分解剤または生物分 解剤を加えると、本考案環境保全用発泡袋は、更に経時的に分解する為に実用性 も高まる。[0006] The component ratios and conditions of one embodiment of the present invention according to the above-described manufacturing process are as follows. a. Polyethylene (PE) 69.8% b. Calcium carbonate (CaCO3) 30% c. Blowing agent-azo compound (AZO) (dimethyl acid) 0.2% d. Temperature control: 180 ° C. When the above-mentioned components are manufactured by blow molding in the manufacturing process shown in FIG. 1, foaming bags can be easily written on the surface with a pencil or a ballpoint pen. In addition, this foam bag for environmental protection becomes powdery when incinerated, and does not stick to the walls inside the incinerator and does not cause fire spread. Further, when an appropriate ratio of a photodegrading agent or a biodegrading agent is added to the composition, the foamed bag for environmental protection according to the present invention is further degraded with time, so that the practical use is enhanced.
