Abstract: A manufacturing method of an eco friendly foam package material includes a raw material mixing step for mixing raw materials uniformly and thoroughly to form a mixed raw material, a raw material hybrid-melting step for performing a hybrid-melting process to form a hybrid-melted material, a particle forming step for performing the particle forming process by putting the hybrid-melted material into a pelletizer to form plastic particles, and a foam extrusion step. In the foam extrusion step the plastic particles are melted to become a gelatinous state material, and foamed with non-chemical method. Since the properties of the biodegradable polymer are changed by the decomposition enzyme, and further to mix with bio-cellulose and the industrial starch, such that the eco friendly foam package material with compostability is obtained.

Abstract: The invention provides a tape film backing including a mixing layer comprising 40-60 parts by weight of PE and 60-40 parts by weight of EPDM rubber and a PE layer. The invention also provides a tape with an adhesive layer coated on the mixing layer or the PE layer of the tape film backing. The tape and the film backing is a halogen-free eco-material possessing superior physical properties as well as fine electrical insulating properties.

Abstract: A tape backing film is provided, comprising 20 to 80 parts by weight of polyolefin and 20 to 80 parts by weight of EPDM rubber or EPR rubber. The polyolefin comprises 50 to 90% by weight of polyethylene and 50 to 10% by weight of polypropylene.

Abstract: An electrical insulation tape, film backing thereof, and method of manufacturing the film backing. The film backing comprises about 20 to 80 parts by weight of polyethylene, about 80 to 20 parts by weight of EPDM rubber, about 0 to 30 parts by weight of fillers, 0 to 50 parts by weight of flame retardant, and about 0 to 20 parts by weight of processing aids. The film backing has physical properties similar to PVC film backings, and thus can replace the PVC film backing used in the electrical insulation tape.
