ALDEHYDE SCAVENGING COMPOSITIONS AND METHODS RELATING THERETO

摘要

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 substantiallly 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.
