TRANSPARENT LID MATERIAL FOR SEALED CONTAINER

摘要

PURPOSE:To develop a transparent lid material for a sealed container by a method wherein an oxygen barrier film absorbs moisture by retort sterilization to reduce a drop in oxygen barrier property and discharging speed of moisture from the oxygen barrier film is increased to increase recovery speed of the oxygen barrier property. CONSTITUTION:A transparent lid material for a sealed container comprises a film/oxygen barrier film/structural material film/sealant film having water vapor permeability of 15cc/m<2>.24hr.1atm/100mum or higher.
