High-elasticity tear-proof polyethylene cast winding film

The invention discloses a high-elasticity tear-proof polyethylene cast wound film, which comprises the following components in percentage by weight: 55-70% of low-density polyethylene, 28-35% of metallocene, 1-3% of an olefin-based elastomer and 0.5-1.5% of a binder. The high-elasticity tear-proof polyethylene tape casting wound film has excellent strength and tensile performance and good tensilerebound performance and is not easy to damage. 本发明公开了一种高弹性防撕裂聚乙烯流延缠绕薄膜，按重量百分比计，由以下组分组成，低密度聚乙烯55-70％、茂金属28-35％、烯烃基弹性体1-3％和粘结剂0.5-1.5％。该高弹性防撕裂聚乙烯流延缠绕薄膜具有强度和拉力性能优良，拉伸回弹性能好，不易破损。
