Corsico, Italy-based PlastiBlow srl is focused on developments to use recycled or post-consumer material with extrusion blow moulding machines.
Initially a brand introduced in 1972, PlastiBlow has been an independent partner of Plastimac Group since 1981.
PlastiBlow supplies systems to produce bottles with recycled resin in monolayer or two- and three-layer configurations.
During a growth spurt last year, the company expanded its production area and built a new headquarters.
PlastiBlow Sales Manager Frank Varuzza said the company has seen a consistent increase in the number of machines sold to process post-consumer material.
The two markets currently keeping the company busiest are home and personal care products, particularly detergents, cleaners and sanitisers, Varuzza said in an email.
"We expect to see this business segment grow further and are thus developing new ideas to enable our machines to perform more," Varuzza said.
PlastiBlow has made several improvements to its existing products, Varuzza said, pointing to a special treatment to extend the life cycle of screws and barrels.
Also, the extruder processing the post-consumer material now is equipped with a screen changer that can be actuated with an electric motor instead of manual or hydraulic operation.
Screen changers are usually mounted on the main extruder to capture any impurities or "unmelts" while processing regrind or post-consumer resin.
"Due to the fact that our machines are all-electric, we generally mount a manual screen changer. This means that when the filter gets dirty, you have to manually operate a lever on top of the screen pack and change the filter," Varuzza said. "With the electric actuated system, you can do this safely from the operator panel and then just quickly change the filter and get back in production."
