A consumable package for use in melt-processing operation comprises a container and a melt-processable product such as polymers, elastomers, or additives. The container is formed from a film made from a random ionomer copolymer comprising of ethylene and 20-45 wt % of an unsaturated monocarboxylic acid, the copolymer being neutralized with a metal ion such as lithium, sodium, magnesium, or zinc. The film has a low melting point and a stiffness of greater than 400 megapascals.
