Abstract

The present invention relates to a multilayer film composition for packaging bitumen. The multilayer film is developed to withstand hot bitumen filling at 100°C with external cooling and dissolve completely into molten bitumen at 150 °C. The multilayer film comprises of an inner layer in contact with the bitumen comprising of a blend of 75-100 % ethylene-vinyl acetate copolymer and 0-25 % of a polymer selected from a group comprising of ethylene alpha-olefin copolymer and branched ethylene homopolymer and a plurality of outer layers comprising of 100 % ethylene-vinyl acetate copolymers. The multilayer film composition further comprises of additives to improve the properties of the film. The invention also discloses a method of packaging hot molten bitumen using the multilayer film.
