Description
本発明は、カールの少ないボイド含有ポリエステル系フィルムに関し、さらに詳しくは後加工時のハンドリング性および、給排紙特性に優れ各種印刷用、カード用フィルムとして好適な空洞含有ポリエステル系フィルム及びその製造方法に関する。 The present invention relates to a void-containing polyester film with less curling, and more specifically, a void-containing polyester film excellent in handling properties during post-processing and paper supply / discharge characteristics, and suitable for various printing and card films, and a method for producing the same About.
本発明の目的は、上記従来技術の欠点を解消し、空洞含有構造に由来する優れた特性(軽量、クッション性など)と良好なハンドリング性(搬送性)とを兼ね備えたフィルム及びその製造方法を提供することにある。 The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to provide a film having excellent characteristics (light weight, cushioning properties, etc.) derived from the cavity-containing structure and good handling properties (transportability) and a method for producing the same . It is to provide.
本発明は、上記のような状況に鑑みなされたものであって、上記の課題を解決することができた空洞含有ポリエステル系フィルム及びその製造方法とは、以下の通りである。 This invention was made | formed in view of the above situations, Comprising: The void-containing polyester-type film which could solve said subject, and its manufacturing method are as follows.
本発明の第1の発明は、ポリエステル樹脂に非相溶の熱可塑性樹脂に由来する空洞をフィルム内部に多数含有する空洞含有ポリエステル系フィルムであって、該フィルムは酸化チタン粒子を0.5〜20.0重量%含有し、下記(a)または(b)の条件でフィルムを保存したフィルムを切り出し、この切り出したフィルムを無荷重の状態で、(Tg+30)℃で30分間熱処理した後のカール値が1.0mm以下であることを特徴とする空洞含有ポリエステル系フィルムである。
(a)500mm四方に断裁し、室温で6ヶ月保存
(b)直径6インチの管にロール状に1000m巻いたものを、室温で3ヶ月保存
A first invention of the present invention is a void-containing polyester-based film containing a large number of voids derived from a thermoplastic resin incompatible with a polyester resin inside the film , and the film contains titanium oxide particles of 0.5 to Curl after cutting out a film containing 20.0% by weight and storing the film under the following conditions (a) or (b), and heat-treating the cut out film at (Tg + 30) ° C. for 30 minutes under no load A void-containing polyester film having a value of 1.0 mm or less.
(A) Cut to 500 mm square and stored for 6 months at room temperature (b) Stored 1000 m in a roll on a 6 inch diameter tube for 3 months at room temperature
第2の発明は、前記空洞含有ポリエステル系フィルムの厚みが50〜500μmであることを特徴とする第1の発明に記載の空洞含有ポリエステル系フィルムである。
第3の発明は、ポリエステル樹脂に非相溶の熱可塑性樹脂に由来する空洞をフィルム内部に多数含有する空洞含有ポリエステル系フィルムの製造方法であって、該フィルムは酸化チタン粒子を0.5〜20.0重量%含有し、フィルムの延伸工程及び熱固定固定の少なくともいずれかの工程で、フィルムの表裏の温度または熱量を異なる値とすることによって、
下記(a)または(b)の条件でフィルムを保存したフィルムを切り出し、この切り出したフィルムを無荷重の状態で、(Tg+30)℃で30分間熱処理した後のカール値を1.0mm以下に制御することを特徴とする空洞含有ポリエステル系フィルムの製造方法である。
A second invention is the void-containing polyester film according to the first invention, wherein the void-containing polyester film has a thickness of 50 to 500 μm.
3rd invention is a manufacturing method of the cavity containing polyester-type film which contains many inside the film the cavity derived from the thermoplastic resin incompatible with a polyester resin, Comprising: This film contains titanium oxide particle 0.5- By containing 20.0% by weight, the temperature or the amount of heat on the front and back of the film are different values in at least one of the film stretching step and the heat fixing step,
A film storing the film under the following conditions (a) or (b) is cut out, and the curled value is controlled to 1.0 mm or less after the cut film is heat-treated at (Tg + 30) ° C. for 30 minutes under no load. It is the manufacturing method of the void containing polyester-type film characterized by doing.
