MEDIUM MODULUS FILM COMPRISING SUBSTANTIALLY LINEAR POLYETHYLENE AND FABRICATION METHOD
Medium modulus polyethylene films with improved tear performance are made for heavy-duty packaging applications and hot-fill uses. Film compositions contain high molecular weight linear polyethylene and a substantially linear ethylene/ alpha -olefin interpolymer. The film is at least about 1.25 mils...

| description | Medium modulus polyethylene films with improved tear performance are made for heavy-duty packaging applications and hot-fill uses. Film compositions contain high molecular weight linear polyethylene and a substantially linear ethylene/ alpha -olefin interpolymer. The film is at least about 1.25 mils (31 microns) thick, has a film density in the range of 0.923 to 0.95 grams/cubic centimeter (g/cc) and typically has a tear strength or impact resistance at least 30 percent greater than current industrial polyethylene film. The novel film has good dimensional stability and strength poroperties which allow significant down-gauging savings.
Des films de polyéthylène de module moyen et à résistance à la déchirure améliorée sont destinés à des applications d'emballage surrésistant et à des utilisations de remplissage à chaud. Les compositions de ces films contiennent un polyéthylène linéaire de poids moléculaire élevé et un interpolymère d' alpha -oléfine/éthylène sensiblement linéaire. Ce film présente une épaisseur d'au moins environ 1,25 millièmes de pouce (31 microns), une densité comprise dans une plage de 0,923 à 0,95 g/cm et, généralement, une résistance à la déchirure ou aux chocs supérieure d'au moins 30 % aux films de polyéthylène industriels couramment utilisés. Ce nouveau film présente une stabilité dimensionnelle et des caractéristiques de résistance supérieures, qui permettent de réaliser des économies appréciables grâce à une réduction du calibre. |
