The present invention relates to a polyester product having a relatively high atypical density of greater than 1 g/cm.sup.3 at 25° C., the polyester product comprises the reaction product of one or more C2 to C12 polybasic acid and one or more polyol. The invention also relates to methods of making the polyester product, compositions containing or comprising the polyester product and the use of such compositions. More especially, the polyester containing compositions may advantageously be utilised in aqueous environment applications, or other applications, where environmental containment is an important consideration.

Ethylene oxide composition having a recycle content value is obtained by reacting an ethylene stream containing recycle content ethylene to make a recycle content ethylene oxide or by deducting from a recycle inventory a recycle content value applied to ethylene oxide composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by ethylene oxide M manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil. An alkylene diol composition and/or an alkylene diol polyester composition having a recycle content value that is obtained by reacting a recycle content feedstock to make a recycle content alkylene diol or alkylene diol polyester or by deducting from a recycle inventory a recycle content value applied to an alkylene diol composition and/or alkylene diol polyester. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an alkylene diol or alkylene diol polyester manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

The presently disclosed subject matter is generally directed to a packaging film constructed from water-dispersible and/or biodegradable compositions. Particularly, the disclosed film comprises a first layer constructed from one or more water-dispersible materials, such as water-dispersible paper. The film further comprises a second layer constructed from one or more biodegradable materials, such as poly(hydroxyalkanoate). The first and second layers can be constructed to form a packaging material used to enclose a wide variety of products, including liquids and moisture-sensitive solids. Advantageously, the disclosed film (and associated packaging materials) are dissolvable in water and/or biodegrade when exposed to landfill conditions and/or water.

The present invention is a multi-component fiber includes a core and a sheathing surrounding the core. The core includes a first aliphatic polyester or copolymer of an aliphatic polyester. The sheathing includes a second aliphatic polyester or copolymer of an aliphatic polyester or a polyamide, and a hydrophobic agent. The second aliphatic polyester or copolymer of an aliphatic polyester or a polyamide has a melt flow index of between about 0.5 and about 19.5 g/10 min using a 2.16 Kg weight at 190° C.
