Mexico City — A large white tent located just outside of the back corner of Hall D at Plastimagen 2019 in Mexico City was the spot where one company set out to prove the importance of plastics recycling.
Sure, Maquinaria Industrial Cabrera S.A. de C.V. had plenty of brochures and booklets talking about its plastics machinery.
But the company, known as Maincasa, also showed attendees during the trade show in early April how the equipment could turn recycled low density polyethylene film into brand new, bright-white T-shirt bags emblazoned with the company's logo.
Maincasa had another booth on the main show floor where the company displayed injection molding machinery producing waste cans. During production, attendees lined up patiently along the side of the company's booth, waiting for their chance to receive a free garbage container.
But back in that white tent, where food trucks also sat on one side, Maincasa assembled an entire production line of equipment to show off recycling machinery.
Men, at one end of the line, fed used low density polythylene film onto a conveyer that took the material into a shredder capable of handling some 1,200 kilograms per hour. From there, the recycled LDPE was melted, filtered, extruded and made into pellets.
The process was loud — very loud — as multiple machines ran at the same time to create the production line.
These dark gray pellets were then master batched with white pigment and sent to a blown film extrusion machine to create film that was then rolled and eventually moved to a printing machine, and then to a bag-making machine.
