FIELD: food production industry. SUBSTANCE: this actually relates to repeated use of plastic bottles which are filled with food products. Method for washing of bottle-type vessels intended for containing food products or drinks and adapted for repeated use includes washing of vessel with water solution at temperature higher than 70 C. Multiple-use vessel is manufactured from homopolymer or copolymer or of their mixture. Material is transparent and has average degree of crystallization above 30%. Thickness of vessel walls is over 0.35 mm in body, and over 1.0 mm in bottom. Application of aforesaid method of washing and design of vessels improves mechanical properties and chemical stability to various food products, gas impermeability is improved. Residual fouling after washing is also reduced. EFFECT: higher efficiency. 22 cl, 2 tbl
