Aiming at solving the difficult problem that plastic bottles are inconvenient for batch squashing, the invention discloses a quick rolling device for plastic recycling. The quick rolling device comprises a baseplate, a placing plate, support rods and sleeves, wherein teeth are uniformly welded on the surface of the placing plate; a baffle is fixedly mounted on the inner side of the surface of theplacing plate; a fastening screw is mounted between each support rod and the corresponding sleeve; a motor is fixedly mounted at the upper end of each support rod; a rotating shaft is mounted on the inner side of each motor; a rotary rod is fixedly mounted at the inner end of each rotating shaft; a connecting rod is fixedly mounted between the rotary rods; a fixed drum is fixedly mounted in the middle of the connecting rod; and an extrusion drum is fixedly mounted on the lower side of the fixed drum. According to the quick rolling device for plastic recycling, the plastic bottles are rolled bythe extrusion drum to be conveniently squashed; since the motors are used for driving, manpower is relieved; and the quick rolling device for plastic recycling is simple in structure, reasonable in design and convenient to operate and is safe and reliable.

The invention belongs to the technical field of petrochemical engineering, and particularly relates to a method for producing an ethylene raw material, which comprises the following steps of: mixing a waste plastic material flow with hydrogen, decolorizing the waste plastic through a fixed bed hydrogenation reactor A filled with a catalyst, and removing metals, sulfur, nitrogen and other impurities to obtain a material flow I; and mixing the material flow I with external hydrogen again, cracking the material flow I through a fixed bed hydrogenation reactor B filled with a catalyst to obtain a material flow II containing an ethylene raw material, and fractionating the material flow II to obtain the ethylene raw material. Waste plastic recycling is achieved, the source of the ethylene raw material is expanded, and the circulation process of the ethylene raw material, ethylene propylene, polyolefin plastic and waste polyolefin plastic is formed.

An improved nylon-free recyclable multilayer package and a method for manufacturing the same is provided that addresses the shortcomings of currently available recyclable materials for flexible packaging and containers. One object of embodiments of the present invention will be to provide a flexible plastic package suitable for curbside recycling, for example, a package that may be in compliance with recyclability as defined by the Association of Plastic Recyclers (APR). One such embodiment comprises a package manufactured from a material that is substantially free of nylon. Another or a second embodiment comprises a package manufactured from a material using a certain optimized ratio of compatibilizers in order to achieve suitable packaging performance and standards for recyclability. The flexible recyclable multilayer packaging material comprises a first laminate film and a second laminate film. The first laminate film further comprises, in order: a first sealable polyethylene layer with low initial seal band defining an exterior layer of the first laminate film; a second sealable polyethylene having a certain pre-determined thickness; a first tie layer; a first gas barrier layer of ethylene vinyl alcohol (EVOH); a second tie layer; a second sealable polyethylene layer; and a third sealable polyethylene layer. The second laminate film further comprises, in order: a first sealable polyethylene layer with low initial seal band defining an exterior layer of the second laminate film; a first sealable polyethylene layer having a certain pre-determined thickness; a first tie layer; a first gas barrier layer of ethylene vinyl alcohol (EVOH); a second tie layer; a second sealable polyethylene layer; a third sealable polyethylene layer; and wherein the flexible material is substantially free of nylon.
