Description

本発明は、深絞り成形用包装材料に関するものである。   The present invention relates to a packaging material for deep drawing.

深絞り包装は、真空、圧空、真空圧空成形などで深絞り成形され、くぼみを設けた底材のくぼみに被包装物を収納し、平らなシートやフィルムからなる蓋材でシール密封した包装である。   Deep-drawing packaging is a packaging that is deep-drawn by vacuum, compressed air, vacuum / pressure forming, etc., contains the package in a hollow in the bottom, and is sealed and sealed with a lid made of a flat sheet or film. is there.

深絞り包装では、スライスハムや、ソーセージなどの畜肉加工品やその他薄型の製品や部材の包装に用いられている。そして、平らな蓋材に印刷がなされ、深絞り成形された底材は、無印刷や無地で用いられ、あるいは着色樹脂が用いられていて、印刷の見当を考慮する必要がなかった。また、底材は無延伸ポリプロピレンや無延伸ナイロンが積層された真空、圧空、真空圧空成形性のよい積層フィルムが使用されてきた（例えば、特許文献１）。   Deep-drawing packaging is used for packaging sliced ham, processed meat products such as sausages, and other thin products and components. The bottom material printed on the flat lid material and deep-drawn is used without printing or with a solid color, or with a colored resin, so there is no need to consider printing registration. In addition, a laminated film having good vacuum, pressure, and vacuum / pressure forming properties in which unstretched polypropylene or unstretched nylon is laminated has been used as the bottom material (for example, Patent Document 1).

最近になって、店頭で底材が上になって展示されることがあり、底材にも表示印刷が要求されるようになると、底材と蓋材の印刷見当、底材の印刷と深絞り成形型との見当、底材の印刷とシール型との見当が問題となってきた。   Recently, there are cases where the flooring is displayed at the storefront. When display printing is also required for the flooring, printing registration of the flooring and the lid, printing of the flooring and the depth of the flooring are required. The registration with the drawing mold, the printing of the bottom material and the registration with the seal mold have become problems.

しかし、前述の深絞り成形性の良い無延伸ポリプロピレンなどを印刷基材とした深絞り成形用包装材料では、印刷ピッチ寸法安定性が悪く、底材として良好な印刷ピッチ寸法安定性を得ることができない。   However, the deep-drawing packaging material using the above-mentioned non-stretched polypropylene with good deep-drawing formability as a printing substrate has poor printing pitch dimensional stability and can obtain good printing pitch dimensional stability as a bottom material. Can not.

そこで、印刷ピッチ寸法安定性の良い１６μｍの２軸延伸ポリエチレンテレフタレートフィルムを印刷基材として採用すると、見当の問題は解決されるが、今度は深絞り成形性が悪くなり、浅絞りしか出来ないと言う二律背反的な問題があった。   Therefore, if a 16 μm biaxially stretched polyethylene terephthalate film with good printing pitch dimension stability is used as a printing substrate, the problem of registration is solved, but this time the deep drawability becomes worse and only shallow drawing is possible. There was a contradictory problem to say.
