Description
本発明は、生分解性フィルム並びにこれを用いた生分解性容器及び生分解性防湿紙に用いる防湿層用ワックスに関する。 The present invention relates to a biodegradable film, a biodegradable container using the biodegradable film, and a moisture-proof layer wax used for biodegradable moisture-proof paper.
従って、本発明の目的は、防湿性に優れた生分解性フィルム並びにこれを用いた生分解性容器及び生分解性防湿紙に用いる防湿層用ワックスを提供することにある。 Accordingly, an object of the present invention is to provide a biodegradable film excellent in moisture resistance, a biodegradable container using the same, and a moisture-proof layer wax used for biodegradable moisture-proof paper.
本発明は、生分解性のマイクロクリスタリンワックス及び生分解性の高分子物質を含んでいる防湿層用ワックスを提供することにより、前記目的を達成したものである。 The present invention achieves the above object by providing a moisture barrier wax containing a biodegradable microcrystalline wax and a biodegradable polymer substance .
以下、本発明の防湿層用ワックスを、生分解性フィルムに適用した好ましい実施形態に基づいて説明する。ここで、本発明において、生分解性（フィルム）とは、フィルムを構成する主な成分が生分解性を有することを意味しており、酸化防止剤やスリップ剤等の添加剤や全ての成分にまで生分解性を要することを意味するものではないが、フィルムの構成成分が元々天然物として存在する形態まで分解し得るものであることが好ましい。 Hereinafter, the wax for a moisture-proof layer of the present invention will be described based on preferred embodiments applied to a biodegradable film. Here, in the present invention, biodegradability (film) means that the main components constituting the film have biodegradability, and additives such as antioxidants and slip agents and all components Although it does not mean that biodegradability is required, it is preferable that the constituent components of the film can be decomposed to a form originally existing as a natural product.
先ず、本発明の防湿層用ワックスを用いた生分解性フィルム（以下、単に生分解性フィルムという。）について説明する。
本発明の生分解性フィルムは、二つの生分解性樹脂層の間に生分解性の防湿層を備えている。
First, a biodegradable film (hereinafter simply referred to as a biodegradable film) using the moisture barrier layer wax of the present invention will be described.
The biodegradable film of the present invention includes a biodegradable moisture-proof layer between two biodegradable resin layers.
本発明の生分解性フィルムにおける、前記生分解性の防湿層（以下、単に防湿層ともいう）は、前記熱成形性を得る上で、生分解性を有する防湿層用ワックス（以下、単にワックスともいう。）を主成分として形成することが好ましく、特に、熱成形が容易な点からワックスが好ましい。 In the biodegradable film of the present invention, the biodegradable moisture-proof layer (hereinafter also simply referred to as a moisture-proof layer) is a moisture-proof layer wax (hereinafter simply referred to as a wax) having biodegradability in obtaining the thermoformability. It is preferable that the main component is formed as a main component, and a wax is particularly preferable from the viewpoint of easy thermoforming.
前記ワックスには、前記生分解性樹脂層との接着性の点からマイクロクリスタリンワックスを用いる。 Wherein the wax, using a microcrystalline wax from the viewpoint of adhesion to the previous SL biodegradable resin layer.
本発明の生分解性のフィルムは、上述のような最終的な使用形態においても、前記その端部から前記防湿層の成分が外部にもれ出さないように上述の二つの生分解性樹脂層どうしの融着処理が施された形態とすることが好ましい。例えば、包装袋やパウチ容器の形態とする場合には、その封止部分において各フィルム端部の二つの前記生分解性樹脂層どうしを融着し、前記成分のもれを防止することが好ましい。また、容器本体に本発明の生分解性フィルムを被覆する容器の場合には、容器を覆うように圧空成形や真空成形によってフィルムを成形した後、不要な部分をカットする際に、加圧しながら溶断する等して二つの前記生分解性樹脂層の融着処理を施し、前記成分のもれを防止することが好ましい。さらに、本発明の生分解性フィルムを成形して単体で容器の形態とする場合にも、上記フィルムによる被覆の場合と同様に、不要部分のカット時に加圧しながら溶断する等して二つの前記生分解性樹脂層の融着処理を施すことが好ましい。 The biodegradable film of the present invention has the two biodegradable resin layers described above so that the components of the moisture-proof layer do not leak out from the end portions even in the final use form as described above. It is preferable to have a form in which two fusion processes are performed. For example, in the case of the form of a packaging bag or a pouch container, it is preferable that the two biodegradable resin layers at the end of each film are fused together at the sealing portion to prevent leakage of the components. . In addition, in the case of a container in which the biodegradable film of the present invention is coated on the container body, after forming the film by pressure forming or vacuum forming so as to cover the container, while cutting unnecessary portions, pressurizing Preferably, the two biodegradable resin layers are subjected to a fusion treatment by fusing or the like to prevent leakage of the components. Furthermore, even when the biodegradable film of the present invention is molded into a single container, as in the case of coating with the film, the two above-mentioned ones may be cut by pressurizing while cutting unnecessary portions. It is preferable to subject the biodegradable resin layer to a fusion treatment.
