In the latest episode of the Magnum Systems Podcast, AIM, host Mike Abare, and guest Wayne Revell, an application engineer focusing on packaging at Magnum Systems, discussed the complexities and advancements in valve bag sealing. The conversation provided invaluable insights for anyone involved in the packaging industry, particularly those dealing with consumables for humans or animals and other products requiring stringent packaging protocols.
The Essence of Valve Bags
Wayne Revell set the stage by explaining the basic concept of a valve bag—a packaging traditionally made from paper and designed to be filled through a spouted opening. The "passive seal" has historically kept the product inside the bag, relying on the product's pressure against the seal to remain closed. However, this method leaves room for potential contamination and product leakage, raising concerns for businesses aiming to maintain the highest standards of cleanliness and product integrity.
"Many customers are not satisfied with their products being displayed and with product leaking out onto the display floor in their business," Wayne states, highlighting the need for a more secure sealing method.
The Evolution of Sealing Methods
The discussion transitioned into the evolution of sealing techniques, from simple tuck-in sleeves to more sophisticated methods like ultrasonic sealing and heat jaw sealers. The shift toward these advanced sealing methods addresses the industry's need for better protection against contamination and leakage.
Ultrasonic Sealing: A Game Changer
Ultrasonic sealing is a focal point of the conversation, with Wayne providing a detailed overview of its advantages, such as not requiring traditional heat, which can benefit certain products. However, the technique isn't without its challenges, including cost and the limitation on the production rate.
"The advantage is that it doesn't use traditional heat. So the seal is made by high-frequency sound, and the amplified high-frequency sound drives the product away from the sealing area and causes the plastic to bond itself together," Wayne elaborated, showcasing the innovative nature of ultrasonic sealing.
Balancing Cost and Efficiency
Cost, production rates and the potential need for multiple spouts to increase production were discussed as critical considerations when choosing a sealing method. The conversation highlighted the importance of aligning the sealing process with businesses' operational objectives and budget constraints.
Safety and Automation in Ultrasonic Sealing
Addressing concerns around safety and the potential for automating the ultrasonic sealing process, Wayne reassured listeners that, despite some limitations, ultrasonic sealing presents a safe and viable option for many applications, especially when integrated with automated systems for improved efficiency.
A Customer-Focused Approach
Mike and Wayne emphasized the importance of working closely with customers and bag vendors to ensure the chosen sealing solution meets each application's specific needs. This collaborative approach is crucial for navigating the complexities of valve bag sealing and achieving optimal outcomes.
"There's no reason to waste the customer's time leading them down the road to something they can't afford to implement," Wayne said, underlining the value of transparency and proper qualification in customer engagements.
The comprehensive discussion in this episode of AIM is a must-listen that illuminates the critical aspects of valve bag sealing, offering listeners expert advice and guidance. Focusing on innovation, safety and customization, Mike Abare and Wayne Revell's insights reinforce Magnum Systems' commitment to addressing the challenges and opportunities in packaging solutions.
