Partnering for precision: SigmaQ and MM Board & Paper optimise folding carton packaging performance
When MM Board & Paper’s Technical Product Services (TPS) expert Michael Zelingr visited SigmaQ, a prominent packaging converter based in Guatemala City, the objective was clear: collaborate on optimising the performance of high-spec folding cartons for a major FMCG brand.
Through hands-on collaboration, SigmaQ and Zelingr identified opportunities for fine-tuning steps in the converting process. This resulted in a clear demonstration of how partnering with MM adds value in terms of quality, consistency, performance and running packing lines without unnecessary interruptions.
Maximising the benefits of sustainable folding carton packaging
A leading packaging supplier in Latin America, SigmaQ’s portfolio includes UV-varnished cartons made with MCM® cartonboard, part of MM Board & Paper’s recycled board portfolio. As part of its continuous improvement efforts, SigmaQ relies on MM’s expertise to help ensure that its materials and processes meet the demanding standards of its customer’s folding carton application.
Zelingr’s visit was structured to address areas that could influence overall product reliability—particularly around UV varnish consistency, crease integrity and gluing precision.
Step-by-step folding carton process optimisation at SigmaQ
The SigmaQ team walked Zelingr through the production set-up, beginning in the warehouse. Here they reviewed storage conditions and the climate-wrapped pallets of cartonboard. If pallet wrapping did not appear to be according to in the specification, the team flagged it for quality assessment.
In the printing department, Zelingr and Production Manager Marco A. Jurado, together with operations colleagues, assessed print press settings – especially the printing and coating units. Together they fine-tuned the settings to reduce stress on the cartonboard significantly.
The team proceeded with a deep dive into cutting and creasing at the die-cutting machines – with an intensive review of the die forms in use. Zelingr and the die-cutting crew examined the current state of die-board cutting and creasing lines. Zelingr recommended adapting the make-ready sheet type. The reason: compression in the current make-ready sheet material was sometimes leading to unclean punch cuts and, as a result, re-do costs.
Defining folding carton performance success metrics
In line with MM’s recommended parameters, SigmaQ set itself the goal to eliminate cutting dust from the die-cutting step. “We wanted to optimize the creasing process to reduce bending resistance while achieving precise, reproducible results,” explained Zelingr. “Our measures are designed to significantly reduce the risk of breakage and ensure smooth performance on the customer’s packaging line.”
After assessing gluing machine conditions, SigmaQ technicians and Zelingr identified a path forward for achieving optimal machine performance and minimising quality issues that might arise from the folding carton’s creasing and erecting behaviour.
A partnership approach to operational excellence in folding carton packaging
MM Board & Paper’s in-person, technical engagement exemplifies its commitment to acting as a collaborative partner to customers like SigmaQ. By jointly addressing challenges and identifying practical improvements, MM helps its customers maintain high standards, minimise material waste and support the integrity of premium brand packaging. Through this hands-on collaboration, MM and SigmaQ demonstrate their shared focus on operational excellence in folding carton packaging.
