This disclosure relates to ethylene interpolymer product having intermediate branching. Intermediate branching was defined as branching that was longer than the branch length due to comonomer and shorter than the entanglement molecular weight (M.sub.e). Intermediately branched ethylene interpolymer products were produced in a continuous solution polymerization process employing an intermediate branching catalyst formulation. Intermediately branched ethylene interpolymer products were characterized by a Non-Comonomer Index Distribution (NCID.sub.i), a melt index from 0.3 to 500 dg/minute, a density from 0.858 to 0.965 g/cm.sup.3, a polydispersity (M.sub.w/M.sub.n) from about 2 to about 25 and a CDBI.sub.50 from about 10% to about 98%. A method based on triple detection cross fractionation chromatography (3D-CFC) was disclosed to measure NCID.sub.i.

A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.

A flame-retardant electric cable has a core including at least one electric conductor, an electrically insulating coating and an outermost layer made from a substantially thermoplastic, low smoke zero halogen flame-retardant polymer composition. The composition includes a polymeric base made of at least one polyethylene homopolymer or copolymer having a density of 0.94 g/cm.sup.3 at most. The composition further includes 60-64% by weight of a metal hydroxide, at least 2% by weight of an ammonium coated montmorillonite having average particle dimensions of from 5 to 20 m, and a polysiloxane. The cable has improved reaction to fire performances, especially reduced dripping or absence of dripping during burning, which render it compliant with the requirements of the more recent international standards.
