Use of a structure based on poly(dimethylketene) and objects comprising this structure

The objective of the present invention lies in providing a resin composition which enables water vapor permeability to be controlled over a broad range while maintaining a high gas permeability, together with molded articles or packaging materials comprising said composition, in particular a packaging material for foodstuffs like fruit and vegetables. A thermoplastic resin composition which is characterized in that a polymer (A) containing polyether chains as structural units, polyethylene (B) of density as specified in JIS K6760 of less than 0.91 g/cm and a compatibilizing agent (C) are blended together in proportions by weight of A/B/C&equals;99.5 to 0.5/0.5 to 99.5/0 to 30 (where A&plus;B&plus;C&equals;100); and molded articles comprising said composition, in particular a packaging material for vegetables and fruit cultivation or foodstuffs storage.

Thermoplastic resin composition and molded articles

A gas-impermeable elastic membrane including a co-polymeric gas-impermeable film including OH groups, positioned between two layers of a co-polymer containing blocks of polyamides and of polyesters, with a rubber coating on at least one of the two layers, as well as a method of manufacturing the membrane.

Gas-impermeable elastic membrane and hydropnematic accumulator equipped with this measure

The invention relates to a breathing film constituting a mixture including: (a) at least one thermoplastic elastomer which has polyether blocks; (b) at least one copolymer including ethylene and at least one alkyl (meth)acrylate. They can be used in combination with fabrics or with nonwovens.

Breathable waterproof film
