LAMINATED FILM FOR BOTTOM MATERIAL OF CONTAINER PRODUCED BY DEEP DRAWING

摘要

A laminated film for a bottom material of container produced by deep drawing, which laminated film excels in not only deep drawing moldability and printability but also design flexibility, being suitable for use in a bottom material for deep drawing packaging employed to carry out filling/packaging for slice products such as hams and sausages. In particular, laminated film (1) for a bottom material of container produced by deep drawing, characterized in that the film comprises outermost layer (10) of a polyester resin having its back surface printed, interlayers (20), the interlayers (20) including gas barrier layer (21), and sealant layer (30) of a polyolefin resin superimposed in this order, that a film for use as the outermost layer (10) has a Young's modulus of 1400 MPa or higher (measured at 23˚C) and a storage elastic modulus at 85˚C of 1000 MPa or less (measured at 110 Hz), and that the outermost layer (10) has a thickness ranging from 10 to 50 mum.
