    摘要: The invention relates to a coextruded, peelable, and biaxially oriented polyester film with a base layer (B) and with at least one outer layer (A) applied to this base layer (B). The outer layer (A) is heat-sealable and features good peelability with respect to nonpolar substrates, such as polystyrene and polypropylene. The heat-sealable and peelable outer layer (A) includes a copolymer of ethylene and polar-ethylene. The invention further relates to a process for the production of the film and to packaging formed from the film.

    摘要: The invention relates to a polyester film comprising at least one base layer (B) and at least one antimicrobially active coating, where this antimicrobial coating a) comprises an ammonium silane of the following formula (I) where R1 and R2 are in each case identical or different and, independently of each other, are hydrogen moieties or C1-C8-alkyl moieties, which are straight-chain or—in the case of C3-C8-alkyl moieties—can be branched, R1 and R2 preferably being identical and being —CH3; in aqueous dispersions, one, two or all of the R1 moieties are hydrogen; n is greater than 0 and smaller than 10, preferably from 2 to 5, and particularly preferably 3; m is greater than 0 and smaller than 30, preferably from 6 to 25, and particularly preferably from 15 to 20, and very particularly preferably 17; X− is chloride, sulfate, or nitrate; and b) the thickness of the coating is smaller than 1 μm, preferably smaller than 0.3 μm, and particularly preferably smaller than 0.15 μm.
