INDUSTRY CHALLENGE

The goal of manufacturers when producing plastic bags, particularly waste bags, is to provide the best bags that do not smell like nasty plastic at the lowest feasible cost. This entails precisely managing the amount of scent metered onto the warm melted sheet plastic. The biggest challenge is to establish an efficient system that can uniformly distribute the fragrances with repeatable accuracy. Many questions arise during the production of high-quality scented plastic bags. Is the exact amount of fragrance provided to the process with certainty? Are the pumps providing additives to the process in an erratic pulsing pattern right now? Is an extra extruder line with a vacuum exhaust cover needed to eliminate fumes? Is it more expensive to buy pre-scented pellets? Are the powerful fragrances from the pellets endangering the workers' health? Is it necessary to have different pellet silos for each scent?

THE ZENITH SOLUTION

The precision gear metering pump system from Zenith provides a continuous pulse-free procedure that ensures accuracy and consistency even at low flow rates. The Zenith B9000 Series pump, which has an accurate, repeatable, pulse-free flow in a compact design, is the ideal solution for effectively metering additives. The B-9000 pumps are available with magnetic drive (mag-drive) sealing, which helps minimize fluid shaft leakage, boosting plant safety and lowering volatile organic compound emissions. The use of a magnetic coupling also minimizes downtime caused by mechanical seal failures and the requirement for buffer fluids.

The pump mechanism delivers a continuous pulse-free method that ensures equal and homogeneous scent dispersion. By adding the scent directly to the bags after they exit the extruder, you may eliminate the requirement for separate pellet silos for each aroma, as well as the need to exhaust the fumes produced by the pellets as they travel from the silos to the extruders.
