This is the pillar that sustains our activity and indispensable condition on which the manufacture and distribution of our products is based. Our thinking is based on offering solutions that last longer and achieve greater efficiency. By offering quality, our customers’ costs can be reduced in the long term. That is why we have been granted certifications, under whose rules our commitment and our work system are based, but always trying to go a step further: ISO 18001, ISO 14001 and ISO 9001.



The management system of the company is participatory and transversal, promoting the responsibility of all personnel involved in all areas of company management.
The involvement of the Company’s Management in its achievement is decisive and therefore helps to generate the cross-cutting characteristic of the policies in general of CSR and in particular of Calvo Sealing.
For this reason, the activities of the company are oriented to a vocation of continuity and permanence, good work and employment practices, special care of our clients, compliance with legislation and sensitivity in respect for the environment.
As very specific characteristics that make up part of the DNA of the company, we can mention fostering teamwork, transparency in both permanent communication and decision-making, maintaining a family environment that obeys our origins.
The human factor is indispensable. We bet for it in the hiring, collaboration and insertion of all kinds of valid people regardless of their age and condition favoring the employment of disabled and youth employment. In this last area, we have an active collaboration with the Chamber of Commerce.


We also care about the environment and try to carry all our production in a sustainable and respectful way with the limited resources of nature. We also contribute to the circular economy, so we take advantage of all the waste generated, which is managed and reused by a recycling company.
