    摘要: The present invention is directed to melt blown polyolefin film which is produced cheaply by melt blowing polyolefin resins which contain 25 to 60 wt% fillers selected from the fillers including an inorganic carbonate, synthetic carbonates, nepheline syenite, talc, magnesium hydroxide, aluminum trihydrate, diatomaceous earth, mica, natural or synthetic silicas and calcined clays or mixtures thereof, having a particle size less than 150 mesh.A further aspect of the present invention is directed to polyolefin resins, especially polyethylene, which are chemically degradable by the incorporation of the combination of the above group of fillers and a metal carboxylate. The metal carboxylates of the present invention are inclusive of a large number of metals, such as cerium, cobalt, iron, and magnesium.

    摘要: The present invention is directed to an additive degradable/compostable package, the combination of a metal carboxylate and an aliphatic poly hydroxy-carboxyl acids, which is added to polyolefin resins in the production of specific products. The addition of the additive degradable/compostable package produces a packaging product which is degradable/compostable. The additive package may include calcium oxide (CaO) to make the modified polyolefin resin more processable. Further, stabilizers or oxidizers may be added to the additive package. The additive package is specifically modified or tailored to the application of the packaging product, e.g. trash bag, compost bag, merchant bag, diaper liner, wrapping film, agricultural film, landfill cover or foamed planks. The present invention further includes the method or process of producing the degradable/compostable concentrates and the improvement of the process of making the degradable/compostable packaging products by the addition of calcium oxide (CaO).

    摘要: The present invention is directed to the process and apparatus for compounding and pelletizing of chemical foaming agents in a high melt resin carrier and producing unique, uniform encapsulated and pelletized chemical foaming concentrates. More specifically, the present invention is directed to the compounding, encapsulating and pelletizing in a high melt resin carrier a highly loaded concentration (5 to 70 wt %) of foaming agents which include an endothermic foaming agent, an exothermic foaming agent or hybrid combinations of these two such that when incorporated into a thermoplastic resin to produce a foamed product will chemically react to form carbon dioxide, nitrogen or hydrogen or mixtures thereof as the active foaming gas.
