摘要: A seal layer for an easy open package consisting essentially of 40% or less, by weight, of a first polymer having a melt flow index of less than 5 selected from the group consisting of ionomers and ethylene-vinyl acetate copolymers, and 60% or more by weight of a second polymer having a melt flow index greater than 20 being selected from the group consisting of low density polyethylene, ethylene-vinyl acetate copolymers, and modified ethylene-vinyl acetate copolymers, whereby the second polymer is a low density polyethylene if the first polymer is an ethylene-vinyl acetate copolymer.
