Abstract: Low energy surfaces based on nanostructured films exhibit advancing and receding contact angles for liquids such that (1) the difference between the advancing and receding contact angles approaches zero and (2) the advancing and receding contact angles approach 180.degree.. The low energy surface of the present invention comprises a nanostructured film coated with an organized molecular assembly (OMA). Advantageously, the chemical and wetting characteristics of the surface can be altered by changing the functionality of the OMA end groups exposed to the environment in contact with the surface of the nanostructured film.

Abstract: A peelable and heat sealable lidstock material comprises a metal or polymer substrate laminated with a film comprising a mixture of a butene-1 and ethylene copolymer, an ethylene homopolymer or copolymer, an inorganic filler and optionally, a propylene homopolymer or copolymer. The filler makes up at least about 18 wt. % of the mixture and is preferably talc having an average particle size of about 1-2 microns and a carboxylic acid surface coating.

Abstract: A bag for packaging heavy materials, exhibiting excellent strength, content packaging performance, stacking performance on the pallets, and anti-collapsing performance. The bag is made of a multi-layer laminated film which comprises an outermost layer of a polyethylene film containing an inorganic filler in an amount of from 20 to 80% by weight and an innermost layer of a polyethylene film containing an inorganic filler in an amount of from 10 to 40% by weight, the outermost layer having on the surface thereof a coefficient of static friction of not smaller than 0.5 (ASTM D 1894), a coefficient of dynamic friction of not larger than 0.5 (ASTM D 1894) and a gloss of not larger than 50% (JIS Z 8741, at a measuring angle of 60.degree.), and the content of the inorganic filler in the innermost layer being from 1/2 to 1/6 of the content of the inorganic filler in the outermost layer.

Abstract: The present invention relates to a multilayered hollow plastic article having an inner first portion of thermoplastic material and an outer second portion of pressure molded thermoplastic material. The second portion of thermoplastic material extends from the closed bottom of the article to the open neck of the article, and the first portion of thermoplastic material extends from the closed bottom to below the neck region of the article. The present invention also relates to the method for preparing said article.
