ABSTRACT:
A processed meat packaging tube is a tube of an orientated laminated film having more than 5% of a shrinkage coefficient at 80.degree. C., less than .+-.5% of percent elongation-shrinkage at 80.degree. C. under tensile modulus of 20 Kg/cm.sup.2 and more than 8 Kg/cm.sup.2 of tightening modulus at 5.degree. C. and more than 1.0.times.10.sup.3 Kg/cm.sup.2 of a tensile modulus of elasticity at 80.degree. C. which is formed by stretching a composite film having an inner layer made of an oxygen barrier thermoplastic resin having less than 1.times.10.sup.-11 cc.multidot.cm/cm.sup.2 .multidot.sec.multidot.cmHg (measured by Seikaken method) of oxygen permeability coefficient and outer layers made of the other thermoplastic resin having smaller water absorption than that of the inner layer.
