ABOUT US

THE LEADING CONTAINER SEAL SPECIALIST IN FRANCE

 

MGJ, this is the story of a French industrial designer and leading manufacturer of a seemingly innocuous little disk that makes all the difference for your product.

For over 50 years we have been one of the world’s leading specialists in the design and manufacture of seals for containers. Our vision and mission go beyond the simple notion of competence.

We quickly outgrew our original role as processors to offer our customers skills and expertise as designers and manufacturers of seals for containers by developing, not only simple lining components, but also sealing solutions that add real value to an end product. Because the essential is often invisible!

TO INTEGRATE THE DESIGN OF SEALS INTO PACKAGING DESIGN

Although they are discreet or even invisible, seals have become a key component of primary packaging because, without them and their advanced properties, essential functions cannot be guaranteed or improved.

To protect and preserve your products, secure them and ensure primary and secondary sealing: the seal is the guarantor of your products, formulas and materials’ life.

Although it seems to be a small commonplace disk, it is actually the result of research, advanced R&D design and cutting-edge production.

 

TO DEVELOP RESPONSES ADAPTED TO NEW FUNCTIONS AND QUALITIES REQUIRED OF SEALS

It involves considering multiple constraints: type of container, type of closure, product compatibility, legislation, certifications, fitting processes, output, tamper-proofing and project economics: volume, throughput, logistics.

It is about selecting materials and processes that will meet challenges: cardboard and polyethylene/expanded polypropylene backings, plastic and metal-plastic surfaced films.

We offer you a wide range of seals: single-piece seals, with or without surface films, and with or without barrier film guaranteeing they are tamper-proof.
