The compositions may include an ethylene polymer having a density in the range of from about 0.947 to 0.962 g/cm3, a melt index of from about 1 to about 10 g/10 min., and another ethylene polymer having a density in the range of from about 0.912 to 0.932 g/cm3, a melt index of from about 0.25 to about 6 g/10 min., wherein the two ethylene polymers have a density difference of equal to or greater than 0.03 g/cm3. In other cases, the composition may include a single component resin with a density in the 0.935-0.955 g/cm3 range with a melt index in the range of 0.3-1.2 g/10 minutes, and wherein the resin comprises a polyethylene polymer.
摘要翻译：本发明涉及配制的组合物，其可以容易地形成瓶盖，而不需要衬垫，同时仍然保持压力要求，例如用于碳酸饮料。组合物可以包括密度在约0.947至0.962g / cm 3范围内的乙烯聚合物，熔体指数为约1至约10g / 10分钟，而另一种乙烯聚合物的密度范围为约0.912至0.932g / cm 3，熔体指数为约0.25至约6g / 10min，其中两种乙烯聚合物具有等于或大于0.03g / cm 3的密度差。在其它情况下，组合物可以包括密度在0.935-0.955g / cm 3范围内的单组分树脂，熔体指数在0.3-1.2g / 10分钟的范围内，并且其中树脂包含聚乙烯聚合物。
