| description | The invention discloses a stretching sleeve film, and belongs to the technical field of high-strength cold stretching sleeve film compositions. In order to guarantee the comprehensive performance of the film, especially puncture resistance and tear resistance, a large amount of ultra-low density polyethylene resin and propenyl elastomer need to be added in the formula, and the propenyl elastomer with higher content enables the production cost to be higher. The composite material comprises a middle layer and an outer layer, wherein the middle layer comprises two kinds of metallocene polyethylene with specific density and MFR and a propenyl elastomer; the component of the outer layer is metallocene polyethylene with specific density. The cold-drawing sleeve film has high tensile property, puncture resistance, tear resistance and rebound resilience, is low in cost, and has excellent comprehensive performance.
一种拉伸套管膜，属于高强度冷拉伸套膜组合物技术领域。为了保证薄膜的综合性能，尤其耐穿刺和耐撕裂性能，在配方中需要加入大量的超低密度聚乙烯树脂和丙烯基弹性体，其中，含量较高的丙烯基弹性体使得生产成本较高。本发明 |
