| description | A hermetically sealed package material and method of making the same which includes a breakaway or peelable seal formed between first and second layers of packaging materials. The first layer of packaging material includes a backing member, preferably formed from lightweight paper stock, which is bonded to a saran film or coating while in a supercooled state by a suitable adhesive, such as, for example, an adhesive selected from the group consisting of styrene-butadiene latex compounds, vinyl printing inks, ethylene-vinyl acetate latex compounds, acrylonitrile-vinylidene chloride copolymers and other adhesive compounds exhibiting equivalent bonding characteristics with saran type films. The second layer of packaging material is formed from an ethylene-polar monomer copolymer film or coating material, such as, for example, an ethylene-vinyl acetate film, which is bonded to a suitable oxygen barrier material such as, for example, an oxygen barrier saran film. The peelable or breakaway seal is formed between the saran film or coating of the first layer of packaging material and the ethylene-polar monomer copolymer film or coating of the second layer of packaging film. |
