FIELD: chemistry.
SUBSTANCE: wall has a layer which contains a polyamide dispersed in a crystallisable polyester and an agent which reduces interphase tension, selected from a group comprising lithium sulphoisophthlate and lithium sulphobenzoic acid. The polyamide contains a product of reacting aminocaproic acid with itself, or a product of reacting A-D, where A is a residue of adipinic, isophthalic, terephthalic, 1,4-cyclohexane dicarboxylic, resorcinol dicarboxylic or naphthalene dicarboxylic acid or mixtures thereof, and D is a residue of m-xylenediamine, n-xylenediamine, hexamethylenediamine, ethylenediamine or 1,4-cyclohexane dimethylamine or mixtures thereof. The polyester contains 85% links obtained from terephthalic acid or dimethyl ester of terephthalic acid. The wall does not contain cobalt compounds.
EFFECT: invention enables to obtain packed articles with high interphase bonding strength and low turbidity.
