摘要： Plastic containers exhibiting reduced plastic resin usage, while maintaining a specific gravity of below 1.0, so as to allow their quick and easy separation using floatation techniques during recycling. Within a layer or portion some of the plastic resin of the container body may be replaced with an inorganic mineral filler material, while within another layer or portion of the plastic container, the plastic material (e.g., polyethylene, polypropylene) may be foamed. The fraction of mineral filler material that may be included within the polyethylene may thus be increased beyond that previously possible while maintaining the specific gravity below 1.0, by also foaming a layer or portion of the polymeric material, so as to create voids therein. This allows significantly less resin material to be employed, while maintaining strength characteristics of the plastic container so as to be at least comparable to existing plastic containers not including such mineral filler materials.

摘要翻译： 塑料容器的塑料树脂使用量减少，同时保持比重低于1.0，以便在回收过程中使用漂浮技术快速方便地分离。 在层或部分中，容器主体的一些塑料树脂可以用无机矿物填充材料代替，而在塑料容器的另一层或部分内，塑料材料（例如聚乙烯，聚丙烯）可以发泡。 因此，通过还可以使聚合物材料的一个或多个部分发泡，从而可以将聚乙烯内包含的矿物填充材料的分数提高到超过先前可能的范围，同时保持比重低于1.0，从而在其中产生空隙。 这允许使用明显更少的树脂材料，同时保持塑料容器的强度特性，以便至少与不包括这种矿物填料的现有塑料容器相当。
