    摘要: The invention relates to multilayer degradable thermoplastic articles. In one embodiment the novel multilayer thermoplastic article comprises a first outer layer, a core layer and second outer layer, wherein the first outer layer and second outer layer are degradable by photo, thermal or chemical means and contain an effective amount of a prodegradant and the core layer is a water-soluble and/or biodegradable core layer, preferably both water-soluble and biodegradable. Bags formed from the multilayer thermoplastic article are useful for use in the composting of organic material.

    摘要: A plastic bag with flexible sidewalls defining an interior volume for holding contents includes a reinforcing feature to resist puncture and/or rupture of the bag. The reinforcing feature may include reinforcing the portion of the bag proximate the bottom edge with additional or thicker thermoplastic material. In various embodiments, the reinforcing feature may be a multilayer strip of plastic material attached along a bottom edge of the bag, either internally or externally, to provide additional material resistant to puncture. The reinforcing feature may be adhesively bonded, heat bonded, or cold bonded to the bag sidewalls. In other embodiments, the sheet material used to produce the bag may be made with varying thicknesses. In addition, methods of manufacturing a bag with such reinforcing features in a high speed automated process are disclosed.

    摘要: The instant invention generally relates to absorbents formed from compacting bentonite-containing materials containing an effective amount of the bentonite particles of a size under 100 U.S. mesh. The absorbent is compacted under effective compacting pressures to form a bentonite material suitable for use as an absorbent and is characterized as having lower costs, increased absorbency over similarly sized and compositionally similar non-compacted bentonite-containing materials and/or improved clump strength when used as an absorbent.
