A plastic film or laminates comprising films blended with flame retardants and corrosion inhibitors to provide simultaneous flame retardancy and corrosion protection for metallic particles when enclosed or packaged in envelopes comprising such films. The additives, while typically mutually antagonistic, are compatible when the flame component is a mixture of an antimony oxide such as antimony trioxide, antimony pentoxide, or zinc borate with a bromoaryl compound commonly bromoaryl having a bromine content ranging from between 36% to 75% and selected from group consisting of decabromodiphenyl oxide, poly (dibromostyrene) and bis-(tribromophenoxy ethane) and with the antimony oxide component in the flame retardant mixture being present in an amount such that the molar ratio of the antimony or zinc to bromine is such that for each mole of the antimony or zinc, approximately between about 2.5 and 3.5 moles of bromine are present; said plastic resin film consisting of a blend of from between about 8% and 12% flame retardant component, from between about 0.5 and 1.5% corrosion inhibiting compound, balance polyethylene resin. An anti-static component may also be added. These films may be laminated to form composites with high concentrations of corrosion inhibitors on the interior layers and high concentrations of flame retardant on the external layers.
