Bag made of a breathable biodegradable uniform film having thickness from 10 to 40 &#x3bc;m and with permeability to water greater than 950 g 30 &#x3bc;m/m24 h in which the biodegradable film comprises starch and possibly a thermoplastic polymer insoluble in water with melting temperature between 60&#xb0; C. and 150&#xb0; C.

Highly-breathable biodegradable film bag

Biodegradable aliphatic/aromatic copolyester comprising: A) an acid component comprising repeating units of: 1) 53 to 54 mol % of an aromatic carboxylic acid; 2) 47 to 36 mol % of an aliphatic acid at least 50% of which is azelaic acid; B) a diol component selected from the group consisting of C, Cand Cdiols said AAPE being disintegrated according to the Standard ISO 20200 in 90 days.

Biodegradable aliphatic-aromatic copolyester

Biodegradable aliphatic/aromatic copolyester comprising 50 to 60 mol % of an aromatic dicarboxylic acid and 40 to 50 mol % of an aliphatic acid, at least 90% of which is a long-chain dicarboxylic acid (LCDA) of natural origin selected from azelaic acid, sebacic acid, brassylic acid or mixtures thereof; and a diol component.

Biodegradable aliphatic-aromatic polyesters

Biodegradable aliphatic/aromatic copolyester comprising: A) an acid component comprising repeating units of: 1) 49 to 63 mol % of an aromatic carboxylic acid; 2) 51 to 37 mol % of an carboxylic acid, at least 50% of which is brassylic acid; B) a diol component; said copolyester being disintegrated according to the Standard ISO 20200 in 90 days.

Biodegradable aliphatic-aromatic polyester

Biodegradable aliphatic/aromatic copolyester comprising 49 to 66 mol % of an aromatic polyfunctional acid; 51 to 34 mol % of an aliphatic acid, at least 70% of which is sebacic acid; and butandiol; and blends containing such copolyester.

Ventilated system for the collection and temporary storage of organic waste which comprises a rigid container provided with a plurality of holes and a removable bag inserted in and supported by said container. The bag is supported by the container in a spaced relationship with respect to the ground or the surface on which said container is placed, so that air can flow from the bottom into the bag. The bag is obtained from a breathable biodegradable plastic.

The biodegradable heterophase compositions comprise partially or completely destructurised and/or complexed starch, a polysaccharide ester and a plasticizer for the polysaccharide ester. In these compositions, the polysaccharide ester constitutes the matrix and the starch the dispersed phase in the form of particles or domains of numeric mean dimension lower than 1 &mgr;m and preferably than 0.5 &mgr;m for at least 80% of the particles. The compositions also comprise an additive which can increase and maintain at values of 4 or more the pH of a solution obtained by placing the compositions in pellet form in contact with water at ambient temperature for 1 hour, with the use of a pellet:water ratio of 1:10 by weight.

Biodegradable compositions comprising starch and polysaccharide esters

Thin-walled biodegradable starch-based articles, particularly sheets of film including at least one first layer of polymeric material including starch and at least one second layer of hydrophobic material, are characterized in that the second layer includes a natural or synthetic wax or mixture of waxes.

Biodegradable starch based articles

A laminated film including at least one first layer of a polymeric material which has a starchy matrix and is insoluble in water or at most expands in water, constituted by destructured starch and an olefinic copolymer and a second layer of a hydrophobic material adhering to the first. Applications are for the packaging of food products and for colostomy containers, for which a very effective barrier against gases and vapours is needed.
