摘要： A polymeric film, multiple-compartment container (io) having an internal frangible seal (20) comprising a curved portion and variable width with a maximum width near the portion of the curve having the smallest radius of curvature, for confining a fluid and related beverage container with a re-closable fitment (26) for storing and delivering two different flavored liquids or the like. The frangible seal (20) of the container will burst when sustained squeezed thus allowing the components in the container to mix within the container (10).

摘要： Provided are functionalized polypropylene adhesive compositions having a desirable range of melt flow rate. These compositions are obtained by grafting at least one impact polypropylene copolymer or by co-grafting a blend containing at least one impact polypropylene copolymer and at least one random polypropylene copolymer. The polypropylene copolymer(s) are grafted with one or more ethylenically unsaturated carboxylic acids or derivatives of these acids, such as anhydrides. Maleic anhydride is a preferred grafting monomer. Also provided is a multilayer film or sheet structure containing at least one barrier layer and at least one adhesive layer produced from the functionalized polypropylene adhesive composition. The multilayer film or sheet structure may also contain at least one predominantly polypropylene-based layer. In addition, a multilayer film or sheet structure is provided in which a barrier layer or a primer layer is adjacent to at least one layer that is produced from a dry blend or a melt blend of the functionalized polypropylene adhesive composition with a polypropylene matrix polymer.

摘要： Co-extrudable adhesive compositions which have excellent adhesion, and which bond well to ionomers, even after long aging, are formed by blending polyethylene with a very low density of 0.86 to 0.91 with polyethylene having a density of 0.91 to 0.935, together with a hydrocarbon elastomer. Acid grafting of any of the components is preferably present. More than an insubstantial amount of polyethylene with higher density than 0.935 is deleterious to initial or age-down peel strength of the adhesive ionomer bond, and is not part of the adhesive composition.
摘要翻译：通过将密度为0.91〜0.935的聚乙烯与0.91〜0.935密度的低密度共聚乙烯与碳氢化合物一起形成，即使经过长时间老化也具有良好的粘合性，并且与离子交联聚合物的共挤出粘合剂组合物弹性体。优选存在任何组分的酸接枝。高于0.935密度的非实质量的聚乙烯对粘合剂离聚物键的初始或老化剥离强度是有害的，并且不是粘合剂组合物的一部分。

摘要： Polyethylene-based adhesive compositions which contain as little as 5 weight percent, and up to 35 weight percent of an acid-grafted metallocene polyethylene have superior peel strength to comparable compositions containing an acid grafted non-metallocene polyethylene. Compositions where the acid-grafted metallocene polyethylene component is based on a metallocene polyethylene having a melt-flow ratio of less than 6.53 and an Mw/Mn of greater than the melt flow ratio less 4.63 are as good adhesive compositions as those based on metallocene resins falling outside these parameters.
