Description

本実施形態の紙容器は、プラスチックフィルムを含まないことが好ましい。ここで言うプラスチックフィルムとは、延伸フィルム、キャストフィルムなどの紙とラミネートして使用するプラスチックフィルムだけでなく、プラスチックペレットなどを溶融して紙の上に直接押し出して製造する溶融押し出しラミネート法によるプラスチックフィルムも含む。なお、プラスチックを水系に分散、溶解させた水系プラスチック樹脂を、コーターで塗工して製造された水系プラスチックフィルムは、ここで言うプラスチックフィルムに含まない。紙にバリア性、強度物性、耐水性、耐油性などの各種性能を付与するためにプラスチックフィルムをラミネートすることは一般的に行われているが、プラスチックフィルムは薄いものでも15μm程度の厚みを有している。プラスチックフィルムをラミネートした紙製品を離解する場合には通常の紙製品を離解する設備ではなく専用設備が必要となる場合があるため、これらのプラスチックフィルムは紙容器を紙原料として再利用する際に、主に離解する工程で障害になるおそれがある。最終製品である紙容器がプラスチックフィルムを含まないものであれば、紙容器の紙原料としての再利用性(リサイクル性)が向上する。なお、水系プラスチック樹脂をコーターで塗工して製造された水系プラスチックフィルムは、フィルムの厚みが1~10μm程度であり、紙原料として再利用する際に障害となるおそれは少ない The paper container of the present embodiment preferably does not contain a plastic film. The plastic film referred to here is not only a plastic film used by laminating it with paper such as stretched film and cast film, but also a plastic produced by melting and extruding plastic pellets directly onto the paper. Also includes film. The water-based plastic film produced by coating a water-based plastic resin in which plastic is dispersed and dissolved in a water-based material with a coater is not included in the plastic film referred to here. It is common practice to laminate a plastic film on paper in order to impart various performances such as barrier properties, strength properties, water resistance, and oil resistance, but even thin plastic films have a thickness of about 15 μm. are doing. When disassembling paper products laminated with plastic film, special equipment may be required instead of the equipment for disassembling ordinary paper products, so these plastic films are used when reusing paper containers as raw materials for paper. , There is a risk of obstacles mainly in the process of disintegration. If the final product, the paper container, does not contain a plastic film, the reusability (recyclability) of the paper container as a paper raw material is improved. The water-based plastic film produced by coating the water-based plastic resin with a coater has a film thickness of about 1 to 10 μm, and is unlikely to be an obstacle when reused as a paper raw material .

本実施形態において紙容器の赤外線透過率は5%以下であることが好ましい。保温性、保冷性に優れる。5%を超えると保温性、保冷性が低下する恐れがある In the present embodiment, the infrared transmittance of the paper container is preferably 5% or less. Excellent heat retention and cold retention. If it exceeds 5%, the heat retention and cold retention may be deteriorated .
