MULTILAYER FILM STRUCTURE

摘要

A multilayer film structure includes: a biaxially oriented multilayer film s tructure comprising: (A) a core layer of high density polyethylene which either includes a minor proportion of a maleic anhydride modified high density polyethylene blended therein and/o r has a skin layer (B) of maleic anhydride modified polyethylene on one side; and (C) a heat sealable or a printable skin layer on one sid e of the core layer, the side being remote from skim layer (B), where present; said s tructure comprising polyethylene of greater orientation in the transverse direction and having a rippled and striated appearance with the r ipples and striations being parallel to the transverse d irection; the structurc may also comprise; (D) a layer of ethylene vinyl alcohol copol ymer on the maleic anhydride modified polyethylene-conta ining layer.
