PEELABLE POLYESTER FILM HAVING IMPROVED OXYGEN BARRIER, PROCESS FOR ITS PRODUCTION AND ITS USE |
摘要 |
<p>Coextruded, biaxially-oriented polyester film with a base layer containing poly-(m-xylylene-adipamide) (MXD6) and a heat-sealable outer layer of polyester based on both aromatic and aliphatic dicarboxylic acid units and containing inorganic and/or organic micro-particles. - Coextruded, biaxially-oriented polyester film with a base layer (B) and a heat-sealable outer layer (A) which is peelable from amorphous/crystalline and crystalline polyethylene terephthalate (APET/CPET), in which (A) contains (a) 80-99 wt% polyester and (b) 1-10 wt% inorganic and/or organic particles with an average diameter (d50) of 2.5-12 microns, (c) the polyester comprises 12-89 mol% aromatic dicarboxylic acid units and 11-88 mol% aliphatic diacid units (total diacid units = 100 mol%), (d) the ratio of particle size (d50) to the thickness (dA) of layer (A) is at least 1, and the base layer (B) contains poly-(m-xylylene-adipamide) (MXD6). An INDEPENDENT CLAIM is also included for a method for the production of this polyester film by melt-coextrusion followed by biaxial stretching and heat-fixing.</p> |
