    摘要: It is an object of the present invention to provide a biodegradable bag for packing a food capable of storing a food such as a snack food which is required to have an oxygen barrier property and a water vapor barrier property, which can be produced at a high speed by a bag making and packaging machine, which can be degraded by naturally occurring microorganisms in soil or water finally to a non-hazardous degradation product, which can be biorecycled, and which is not accumulated in nature. The present invention is directed to a biodegradable bag for packing a food, which comprises a laminated film obtainable by laminating in the following order; a sealant layer comprising a biodegradable polymer; a barrier layer having an oxygen barrier property and a water vapor barrier property; and a barrier layer-supporting substrate layer comprising a biodegradable polymer, said laminated film being heat-sealed in order for the sealant layer to be inside.

    摘要: The present invention relates to a delamination method for recovering constituents of a paper-based multi layered laminated packaged waste. The method comprises using of a mixture of inorganic bases to separate the constituents of the packaged waste and recover paper, plastic and/or aluminium components separately. The paper can be recovered as pulp, the plastic can be recovered as is, and the aluminium can be recovered as a water soluble salt. The delamination method of the present invention is also effective on cardboard-based multi layered laminated packaged waste.
