Environmental respect

SEI is committed to reducing its environmental impact by adopting the latest generation solutions with maximum eco-sustainability and eco-compatibility. For some years now, in fact, SEI has powered its production processes with photovoltaic panels and recycles all PVC, polypropylene, paper, cardboard and metal parts waste using advanced zero-emission systems.

Innovation

Innovation

Years of research, experimentation and development make SEI one of the most innovative companies.
COLPAN
SEI is the first to develop its own COLPAN production system. Although the technique is currently in the public domain, the innovations in technology and construction we introduced on our production lines have transformed the COLPAN: from a simple PVC-coated cardboard to a product that stands out for its quality and finish.
COLPAN 2000
The evolution of the species. Unique on the market to know how to accomplish this advanced and exclusive high-quality materials: PVC foam.
STRATOPAN-P
Designed and manufactured with a keen eye on market demands, STRATOPAN-P is composed of a top quality cardboard plank coupled with a complete coating PP: it is assembled with animal glues.
COLPANPACK
The newest member of the family of coated products, it is certainly the most economical, but also the most versatile. The thicknesses of the coated layers on one side only in phthalate-free PVC, range from two millimeters to a few tenths of a millimeter and use top-quality cartons on the visible side, completed with water-based ink prints.

PP (Polipropilene)

PP (Polipropilene)

Polypropylene is plastic material that is lightweight and compact. It derived entirely from oil, was invented in 1954 by the Italian Nobel Prize winner Giulio Natta. It has been one of the protagonist of the modern “Age of Plastic”for several decades and it is used in many sectors. in SEI we use it for nearly thirty years to produce transparent punched jackets, folders, pocket envelopes, adhesive jackets, display books and binders. It is a non-toxic material, fully recyclable and is particularly suitable for use with photocopies or laser prints. Transparent, neutral, coloured, opaque or multicoloured, polypropylene is processed in our facilities with traditional machinery and advanced technologies developed by our research and development department.

PVC (Polyvinylchloride)

PVC (Polyvinylchloride)

PVC is the classic “plastic material” that appears in the entire modern history of humanity. It is composed only ùby 43% petroleum derivates and 57% common sodium chloride (table salt). It can be found in any industry and it has several uses: from medical to construction, from cars to airplanes, from sports to leisure, from clothing and furnishings, and so on. Like all plastics, if properly collected, it is 100% recyclable with a virtually endless cycle. Beautiful and durable material, it is also extremely versatile: it can be soft, rigid, foamed, transparent, opaque, colored or neutral. In SEI it is used for the production of the most prestigious items such as binders, project boxes, punched and adhesive envelopes, price lists and much more.
