Abstract
Abstract @ A resin laminate is disclosed, which comprises a gas permeation-resistant resin layer having laminated on each side thereof a polyolefin based resin layer, wherein said polyolefin based resin layer contains an inorganic filler in an amount of 20 to 80% by weight based on the total weight of the resin composition. The resin laminate may be provided with a thermoplastic resin layer containing no inorganic filler on the outersurface thereof. The resin laminate has a minimized oxygen gas permeability and has a low calorific value and is useful as a packaging material.
