Abstract

Abstract: Using ethylene/vinyl acetate copolymer (EVOH), polyamide 6 (PA6), metallocene polyethylene (mPE) and linear low density polyethylene (PE-LLD) as raw materials, PA6/EVOH/PA6, PA6/PE-LLD/mPE and EVOH/PE-LLD/mPE three-layer barrier films were prepared via co-extrusion in this paper. The optimal processing technology of three-layer barrier films was obtained by analyzing thermal and rheological properties of raw materials. The results showed that the mechanical and helium barrier properties of PA6/EVOH/PA6 films were the best.

Key words: three-layer co-extrusion film, thermal property, rheological behavior, mechanical property, barrier property
