摘要:
A food-packaging bag the materials of which can be easily recycled. The bag is made of a laminated film composed of a polyester-based low-melting sealant layer, a barrier layer (vapor-deposited layer of a ceramic or metal), and a polyester-based high-melting heat-resistant layer. It is formed by heat-sealing the laminated film so that the polyester-based low-melting sealant layer faces inward.
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.
