Increased Quality And Performance For Heavy Duty Bags

The recent installation of a new servo-driven Amplas converting machine in the Convex Plastics Hamilton plant has significantly increased the quality and performance of their heavy duty bags.

The ability to tightly control the tension of the packaging film throughout the converting process enables the new machine to weld materials in the bed of the machine without stretching the film. This maximises the strength of welds such as tack, angle and spot seals, and significantly reduces any chance of creasing.

The new machine incorporates a high strength lap sealing feature, and a rotating gusseter, which allows both back and front print to be registered. The rotating gussetter also enables the lap seal to be concealed in the gusset.

According to Convex Plastics conversion and extrusion manager, Ray Pickett, the new machine is the latest addition to a range of technologies that Convex Plastics has invested in to maximise quality and service for their customers. The features offered by the new machine, combined with the company's utilisation of state-of-the-art sealing materials and expertise in controlling film properties associated with slip and blocking, will ensure that maximum quality is achieved.

He says, "At Convex Plastics we are constantly driving toward best practice in our quality, equipment, personal, systems and procedures, and installing this piece of equipment is a big step forward in achieving this."
