摘要:
A multilayer film includes a core layer having recycled, commercially used plastic therein and opposed skin layers, at least one of said opposed skin layers including a whitening agent or other pigmenting agent therein to mask any undesired coloration created by the recycled plastic. Laminations employing the above multilayer film also form part of this invention. A method of this invention for making a multilayer film including a core layer with recycled plastic therein includes the steps of: separating a plastic film or label from a package of commercial product; pelletizing the plastic film or label into pellets for introduction into an extruder of a film forming device and introducing the pelletized plastic film or label into said extruder for introducing the recycled plastic film or label pellets into a core layer of a multilayer film.

Disclosed is a method of reclaiming a multilayered film which comprises a plastic layer including polyester (PET), polypropylene (PP), and polyethylene (PE) as main components, and an aluminum layer. The method comprises selective dissolution of aluminum, separation using a difference in specific gravity, selective extrusion using a difference in melting point, and selective dissolution using an organic solvent.

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.

A wrapping multilayer film comprising at least 5 layers of(A) both the outermost layers each comprising an ethylene-.alpha.-olefin copolymer having an ethylene content of at least 50 mol %,(B) layers each comprising a propylene polymer and being disposed between the outermost layers (A), and(C) a layer comprising recycled resins and being disposed between the layers (B).
摘要:
A polymer composite and its method of manufacture using a recycled multilayer material. An example of the recycled multilayer material is comprised of a polyethylene/polyethylene terephthalate/aluminum film that may be extruded with organic filler to obtain desirable performance in wood-substitute products such as deck boards, railing, fencing, pergolas, residential cladding/siding, sheet products, and other applications.

A display device comprising a first receiving layer and a second receiving layer located onto and in direct planar contact with the first receiving layer; a first support later and a second support layer located onto and in direct planar contact with the first support layer; and a sleeve for receiving the first and second receiving layers and first and second support layers.
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.
