Our offers of envelopes range from common paper or PVC in various sizes, to technologically advanced envelopes for security transportation of money, documents and valuable objects. These envelopes, completely non see-through, are made in high density coextruded polyethylene (HDPE) or low density polyethylene (LDPE). Upon request, they can be made in transparent LDPE. Joints are voltaged for high resistance. Our envelopes can be customised with a 6 colour print. Upon request it is also possible to print bar codes or use special ink able to highlight any possible permanent sealing tampering. The vast range and robustness of our items make them the best solution to seal and send any type of document or valuable item, irrespective of form or material.
