Description

本発明は紙ラベルが貼り付けられているプラスチックボトル、ガラスボトル等の被着体に関するものである。
The present invention relates to an adherend such as a plastic bottle or a glass bottle to which a paper label is attached .

食品や非食品などの各種内容物を充填密封したポリエステルボトル等のプラスチックボトルあるいはガラスボトルには、意匠性を向上させ、販売促進を図る等の目的で絵柄などを印刷した各種ラベルが多く装着されている。前記各種ラベルとしては、基材がプラスチックフィルムのものや紙のものが多く使用されている。近年、循環型社会構築の為に、充填された中身が無くなった後に廃棄されたガラスボトルやポリエステルボトルは再利用される場合が多く、その場合表面に装着されているラベルは表面から引き剥がす必要がある。シュリンクラベルの場合は一部を手でカットして引き剥がすことができるが、紙ラベルの場合はボトル表面に種々の接着層を介して接着されているので簡単に引き剥がすことが難しい。紙ラベルとして種々のものが提案されている(例えば、特許文献1参照。)
特開2003−5647号公報
Plastic bottles and glass bottles such as polyester bottles filled and sealed with various contents such as food and non-food are often equipped with various labels printed with designs for the purpose of improving design and promoting sales. ing. As the various labels, a substrate made of plastic film or paper is often used. In recent years, in order to build a recycling society, glass bottles and polyester bottles that have been discarded after filling up are often reused. In that case, the label attached to the surface must be peeled off from the surface There is. In the case of a shrink label, a part can be cut by hand and peeled off. However, in the case of a paper label, it is difficult to peel off easily because it is bonded to the bottle surface via various adhesive layers. Various paper labels have been proposed (see, for example, Patent Document 1).
