60 Years Exploring the World of Metal Packaging

In the 1960s, the canning industry began to flourish in the Region of Murcia and Auxiliar Conservera opened its doors. Since then, we have maintained our commitment to service, offering our customers the products and attention they deserve. 




AC was founded in 1961 as a small family workshop with only two employees working side by side. At that time we manually produced about 40 cans per person per day.

Since our founding, we have always been committed to innovation in order to keep moving forward. This was a period of major investments that would mark AC’s innovative spirit: chain machines, automation of seaming machines, etc.

We continue our journey, evolving and learning every day. During these years we experienced a great technological and material revolution: electric welding and the thinning of tinplate.

We grew more and more and strengthened our national expansion with the opening of the Seville center (1995). At the international level, our main breakthrough focused on the development of the ‘easy-open’ lid.

We entered the 21st century by taking a leap forward in quality and environmental management, achieving ISO 9001 and ISO 14001 certifications in the Torrealta, Molina de Segura, and Mairena del Alcor centers. We created our own Design and Prepress department and acquired state-of-the-art machinery for the lithography section. In this decade, we incorporated new developments in our catalog of Easy-Open lids. In addition, we added new management tools: ERP – SAP, to optimize our processes to the maximum, and we opened an international production center with the new plant in Concepción, Chile.
In this first decade we also grew with the acquisition of several companies in the sector: Unión Metalgráfica, S. A., Metalgráfica de Envases, S. A., and Derivados de Hojalata.

In 2011 we celebrated our 50th anniversary with the inauguration of a pioneering smart warehouse. This is also the decade in which we developed two new centers that would bring us closer to our customers in the North of Spain, in La Rioja, and to those in Germany, in Dortmund, which was a step towards reducing CO2 emissions from the containers we transported. We began calculating the carbon footprint of our processes and adapted all our sites to obtain BRC Packaging certification.

Over this decade we won several awards recognizing our work in personnel management, product innovation, and internationalization: the “Murcia Flexible Company” Award in 2011, the “La Caixa Incorpora Award” in 2015, the “Can of the year Canmaker” Award in 2017, and the “Best International Strategy” Award in 2019.

We started the decade adapting to Covid-19 and working with more vigor than ever. We received an award for training and professional development management, the “Cegos HR 2020 Award,” and another for collaborating with the School of Industrial Engineering of the Polytechnic University of Cartagena (UPCT), the “Mateo Vodopich 2020 Award.” It is also the year in which we created a Chair with the UPCT for the innovation of more sustainable packaging and conservation solutions.
