CN106633342A 一种低熔点包装膜 无效 - 驳回

一种低熔点包装膜
摘要：
本发明公开了一种低熔点包装膜，按质量百分数计，该低熔点包装膜的配方为：乙烯醋酸乙烯共聚物65％；二氧化硅2％；硫酸钡(沉淀法)2％；低密度聚乙烯23％；复合开口母料8％。本发明在配方中添加成核剂二氧化硅，使得包装膜具有良好的透明度；并且熔点控制在90±1℃，熔点稳定，不易破损。该低熔点包装膜特别适用于生产袋宽≤400mm的低熔点包装袋，获得的包装袋尺寸稳定，纵横向物性一致，封合强度高，不易产生形变，不易破损；透明度高，无皱褶，外观优良。
摘要（英）：

The invention discloses a low-melting-point packing film. The low-melting-point packing film is prepared from, by mass, 65% of vinyl acetate copolymer, 2% of silicon dioxide, 2% of barium sulphate (precipitating method), 23% of low-density polyethylene and 8% of compound open master batch. The nucleating agent silicon dioxide is added in the formula, so that the packing film has good transparency. In addition, a melting point is controlled to be 90 +/-1 DEG C and is stable, and the packing film does not easily break. The low-melting-point packing film is especially suitable for a low-melting-point packing bag with the production bag width smaller than or equal to 400 mm, the obtained packing bag is stable in size, convenient in vertical and horizontal physical property and high in sealing strength, does not easily deform, does not easily break and is high in transparency, free of wrinkles and excellent in appearance.
