Description
本発明では、シートの厚みは、100μm以下であることが好ましく、1〜50μmであることがより好ましく、3〜30μmであることがさらに好ましく、5〜18μmであることが最も好ましい。
また、本発明の製造方法では、前記レーザーの強度は95W以上であり、好ましくは95〜130Wである。
レーザー透過性樹脂部材として、ポリエチレンテレフタレート樹脂(E.I.DuPont製 ライナイト(登録商標) 530NC010)を準備した。この樹脂を2軸押出機で溶融混練した後、ペレット化した。
吸収率(%)は、溶着に用いるレーザーの波長において、100%−透過率(%)−反射率(%)にて算出したものを使用した。なお、透過率および反射率の測定は、島津製作所株式会社製UV-VIS-NIR分光光度計(UV3100)を用いて行った。
シートを樹脂部材間に介在させない以外は、実施例1と同様にしてレーザー溶着を試みた。結果を図4および表1に示す。45W〜89Wまでのレーザーパワーにおいては高い溶着強度が確保されたが、100W付近にまでレーザーパワーを上昇させると、焦げ付きが生じ、溶着強度は急激に低下した。
