ABSTRACT:
A coated bottle comprising a bottle having an inner and an outer coating is disclosed. The inner coating applied to the external surface thereof is prepared from non-tacky composite powder particles which are made up of powder particles which have surface deposited thereon comparatively smaller solid particles which are hard and non-tacky. The tacky powder particles comprise a mixture of a thermoplatic elastomer, a specifically defined melt flow modifier, and an adhesion promoter. The smaller, hard particles comprise a specifically defined melt flow modifier which has a glass transition temperature of at least about 20.degree. C. The first coating is applied to the bottle, preferably by electrostatic spraying techniques, and the bottle with the particles is baked to form a smooth coating. An outer coating comprising certain particularly defined synthetic resins, particularly acrylic polymers, is then applied and the coated bottle is again baked until a smooth second coat is formed. The coated bottle is fragment retentive and this coating is not substantially removed or destroyed during the cleaning and sterilization procedures commonly employed by carbonated beverage bottling companies.
