Plastic has become an omnipresent material. Take a look down the aisles of any hypermarket or major retailer and you will find an endless range of products that use it for containers and other types of packaging.
Flexographic techniques are used to print on such packaging. This relief printing method is suitable for many different types of items and has numerous advantages over other printing systems.
Comexi Group Industries, located in the province of Girona (northeastern Spain), was one of Spain’s pioneers in manufacturing machinery for printing on plastic in the 1950s. Although it initially specialized in repairing and maintaining machinery for the paper and textile industries, the company successfully adapted to the new needs of its clients, which wanted to modify their machines to be able to print on plastic film. "It was this need that gave rise to the first printer designed and manufactured by the Comexi Group - the CF 2/35", remembers Manel Xifra, Chairman of the company.
A commitment to the environment and sustainability is one of the elements that differentiates this company from the competition. The company has been at the forefront of changes in the flexible packaging printing industry, “moving towards a cleaner environment with no atmospheric emissions and the lowest possible impact”, points out Xifra.
Aware of the importance of reducing greenhouse gases and appropriately managing its carbon footprint in the industrial world, the Comexi Group is channeling its energy toward making printing solutions without solvent inks.
Two types of curable inks can be used to print without solvents – using ultraviolet radiation (UV) or electron beams (EB). The former, which does not have sufficient energy to initiate the polymerization process, requires the intervention of a photoinitiator, leading to major problems for use in food packaging.
