IPA, originally known as Indústria de Plásticos da Azóia, was founded in 1961, appearing as a small production unit located in Azóia - Leiria.

Its activity was based on the business dynamics of those days, while assisting to the great expansion of the plastic transforming industries.

Initially, the company dedicated itself to the production and sale of toys, flowers and fishing needles. In the following years the abandonment of certain articles of reduced demand was inevitable, leading to the development of articles for household and sanitary use, some of them still in production to the present day.
The 80's were marked by a strategy of product specialization. In 1987, the company owners decided the renaming to Plásticos Domésticos IPA, Ltd. In addition, the Plásticos Domésticos IPA, continued the production and sale of its household and sanitary articles.

To consolidate the adopted specialization strategy it was created Plásticos IPA II, with the purpose of marketing the products manufactured by Plásticos Domésticos IPA and SET. From then on, these two companies had to devote himself exclusively to the development and production.

In 2001, the 3 companies were acquired by Joaquim Ribeiro and Idalina Ribeiro, who in due course, decided to merge them and create Plásticos IPA, SA.

Since then, the bet has been in the technological development of the business, to continue to occupy a prominent place in the market for household products, sanitary accessories and agrochemicals.

With a dynamic and enterprising spirit, the Plásticos IPA SA, has invested in new equipments and products in order to improve and innovate and answers to the growing demands of both national and international markets. In this context, in 2009, the company moved premises, and is now in an industrial park, where their infrastructure has been conceived to the needs of the organization and its employees.
