Title: Growth in the Plastics Industry The plastics processors in Brazil are considered to be a “weak link” of the productive chains in which they are inserted. Plastic processors are a “supplier dominated” industry according to Pavitt’s typology. Nevertheless, some firms in this industry seem to be able to explore the increasing use of plastics in different applications as an opportunity for growth. A question that has not yet been explored is: How do firms surpass the limitations of the industry, evolving in successful growth trajectories? This article analyses the growth dynamics of small companies of low to medium technology in order to explore the factors that stimulate the growth of firms in this industry, focusing on organizational profile and technological learning. A case study is presented in order to illustrate the growth trajectory of a Brazilian plastic processor.Title: Growth in the Plastics Industry The plastics processors in Brazil are considered to be a “weak link” of the productive chains in which they are inserted.

Por outro lado, a crescente utilização dos plásticos em diferentes aplicações representa uma oportunidade para o crescimento dessa indústria. Uma questão ainda não explorada é: Como empresas de transformação de plásticos superam as limitações da indústria, evoluindo em trajetórias de crescimento bem sucedidas? Com o foco na dinâmica do crescimento de pequenas empresas de média-baixa tecnologia, esse artigo busca aprofundar o conhecimento dos mecanismos que estimulam o crescimento de empresas nessa indústria com enfoque em dois aspectos: perfil organizacional e aprendizagem tecnológica.
