Title (EN) WRAP FILM AND BODY WOUND WITH WRAPPED FILM
(FR) FILM D'EMBALLAGE ET CORPS ENROULÉ PAR UN FILM ENVELOPPÉ
(JA) ラップフィルム及びラップフィルム巻回体
Abstract:
(EN) Provided is a wrap film that has excellent adhesion during use, has tension and stiffness, is transparent, exhibits an effect for preventing vertical splitting and an effect for preventing re-winding, does not readily split even after being heated at high temperatures (e.g., over an electric range), has a low frequency of splitting during rewinding, and has exceptional oxygen/water barrier properties. This wrap film has a tensile strength of 100 MPa or higher, a tensile elasticity of 100% or lower, and a tensile modulus of 280 MPa or higher in the direction (TD) perpendicular to the flow direction, and has a tensile modulus of 380 MPa or higher in the flow direction (MD), the crystal long period preferably being 12.5 nm or less.
(FR) L'invention concerne un film d'emballage qui présente une excellente adhérence pendant l'utilisation, qui présente une tension et une rigidité, qui est transparent, qui présente un effet pour empêcher une déchirure verticale et un effet pour empêcher un ré-enroulement, qui ne se déchire pas facilement, même après avoir été chauffé à des températures élevées (par exemple, sur une cuisinière électrique), qui présente une basse fréquence de déchirure pendant le ré-enroulement et qui présente d'exceptionnelles propriétés de barrière à l'oxygène/eau. Ce film d'emballage présente une résistance à la traction de 100 MPa ou plus, une élasticité à la traction de 100 % ou moins et un module de traction de 280 MPa ou plus dans la direction (TD - sens transversal) perpendiculaire à la direction d'écoulement et un module de traction de 380 MPa ou plus dans la direction d'écoulement (MD - sens machine), la longue période de cristal étant de préférence de 12,5 nm ou moins.
(JA) 使用時の密着性の良好な、ハリ・コシ感、透明性、縦裂け防止効果及び巻戻り防止効果を有し、高温(例えば、電子レンジ)で加熱した後にも裂けにくく、リワインド時の裂け発生率が低く、酸素・水バリア性に優れた、ラップフィルムの提供。 流れ方向と垂直な方向(TD)の引張強度が100MPa以上、引張伸度が100%以下、引張弾性率が280MPa以上であり、流れ方向(MD)の引張弾性率が380MPa以上であり、好ましくは結晶長周期が12.5nm以下である、ラップフィルム。
