FIELD: technological processes.
SUBSTANCE: invention relates polymer laminar materials for flexible package, and concerns a peelable film. Film is designed to bond to substrates based on polyester. Film comprises a coextruded multilayer structure comprising: a discontinuous sealing layer based on polyester; an adhesive layer in contact with said discontinuous layer, a gas barrier layer in contact with said adhesive layer containing a gas barrier polymer. Average peel strength between adhesive layer and a discontinuous sealing layer is lower than 15 N/15 mm when measured at a peel angle of 180°.
EFFECT: invention provides a multilayer peelable film for bonding to substrates based on polyester, or with itself, in case of using a three-seam package having acceptable peel strength.
