Abstract
Description
本出願は、2008年6月27日に出願された米国仮特許出願第61/133,356号の出願日の利益を主張する。
本開示は、製造、保存、輸送または使用の間の、基材表面を保護するのに用いるフィルムに関する。本開示は、また、上記フィルムを作製する方法に関する。
1つの実施形態では、マスキングフィルムは、少なくとも1つの三次元剥離面を有する高分子フィルムウェブを含む。
表1の組成を有する一連のフィルムを調製した。
1つの滑らかな接着面および対向する剥離面を有する一連の単層ポリエチレンフィルムを作製した。滑らかなチルロール上に前の実施例で用いた低密度ポリエチレン/スリップ剤のブレンドをキャスティングすることによってフィルムを作製した。図8に見られるように、テクスチャード加工または彫刻エンボスロールでフィルムの反対側に圧力を加えた。テクスチャード加工エンボスロールはゴムから作製され、1.397ミクロン(55マイクロインチ)の粗さを有する表面テクスチャを有していた。彫刻エンボスロールもゴムから作製され、ダイヤモンド形状パターンで一連の深い彫刻溝を有していた。次いで、フィルムの各表面を、180°剥離試験で特別の開発接着強度試験方法を使用して接着についてテストした。結果を表3に記載する。
各側に剥離面を有する一連のポリエチレンフィルムを作製した。彫刻チルロール上に前の実施例で用いた低密度ポリエチレン/スリップ剤のブレンドをキャスティングすることによってフィルムを作製した。チルロールは、ダイヤモンドパターンの形状で一連の深い彫刻溝を含む彫刻面を有していた。図8に見られるように、テクスチャード加工エンボスロールでフィルムの反対側に圧力を加えた。テクスチャード加工エンボスロールはゴムから作製され、1.397ミクロン(55マイクロインチ)の粗さを有する表面テクスチャを有していた。次いで、フィルムの各表面を接着についてテストした。結果を表4に記載する。表4に見られるように、本実施形態では、フィルムは基材に接着しなかった。
表5に記載した組成を有する一連の3層同時押出し成形フィルムを調製した(層2はコア層であり、層1および3は外側すなわち「表皮」層である)。フィルムは、成形スクリーン上に成型し、成形スクリーンは、周囲に巻き付けられ、真空を施して図4Aに表したフィルム材料を形成する薄いワイヤーを有する。フィルムの様々な物理的特性についてテストした。結果を表6に記載する。
