PURPOSE:To prepare the title sheet excellent in impact strength, resistance to heat distortion, and bonding to a lid film by laminating a core layer comprising a PET resin and an olefin resin with skin layers comprising an olefin resin and a specific PET resin. CONSTITUTION:The title sheet comprises a core layer consisting of a PET resin and an olefin resin and skin layers consisting of an olefin resin in a wt. of 1.5-5 times that of the olefin resin in the core layer and a PET resin that is made up of 10-40wt.% copolymer of ethylene glycol and terephthalic acid and 90-60wt.% copolymer of ethylene glycol, terephthalic acid, and 1,4- cyclohexanedimethanol or isophthalic acid. The wt. of the skin layer accounts for 10-40% of the total wt. of the sheet. |
