There are provided multi-layered structures comprising at least one layer that is an ethylene/alpha-olefin copolymer having a density of less than 0.916 g/cc and a melting peak temperature of greater than 118&deg; C. The multi-layered structures comprise at least two layers. Also provided are articles of manufacture produced from the multi-layer structures such as films, containers, pouches, packages, tubing and the like.

Multi-layered polymeric structures including a layer of ethylene copolymer

A heat sealable packaging film producing a peelable seal is formed from a blend of 99 to 75 weight percent of a copolyester and 1 to 25 weight percent of an epoxy-containing impact modifying polymer. The copolyester has a diacid component of at least 50 mole percent terephthalic acid, naphthalenedicarboxylic acid, 1,4-cyclohexanedicarboxylic acid, or mixtures thereof and diol component of about 90 to 35 mole percent ethylene glycol and 10 to 65 mole percent of at least one of diethylene glycol or 1,4-cyclohexanedimethanol.

Polyester packaging films producing a peelable seal

There are provided multi-layered structures comprising at least one layer that is an ethylene/alpha-olefin copolymer having a density of less than 0.916 g/cc and a melting peak temperature of greater than 118&deg; C. The multi-layered structures comprise at least three layers. Also provided are articles of manufacture produced from the multi-layered structures such as films, containers, pouches, packages, tubing and the like.
