Patent

CA 2147828

The present invention relates generally to compositions of polyalkylene imine ("PAI"), particularly polyethylene imine ("PEI") and polyolefin polymer (including copolymers and derivatives thereof); such compositions can be used in producing packaging films for oil containing foods, whereby the film is capable of scavenging unwanted aldehydes from the food product. The preferred compositions comprise a PAI substantially discontinuous phase and an olefinic polymer (including copolymers or derivatives thereof) substantially continuous phase in a weight ratio of PAI to olefinic polymer of about 0.001-30:100 which optionnally also includes a binding agent.
