Case Study: 3 Springs Water Automates Bottle Bundling with Polypack’s TangoII-24L Shrink Wrap Machine

3 Springs Water is known for its high-quality bottled spring water, carefully sourced and packaged. As demand grew, the team at 3 Springs sought a shrink wrap water bottles machine that could keep up with production without sacrificing product integrity or efficiency. That’s where Polypack stepped in.

The project centered around the TangoII-24L shrink wrap system, a fully automated solution equipped with a 90-degree infeed transfer—ideal for high-speed bundling and shrink wrapping of loose water bottles into secure, distribution-ready packs.

A System Designed for Smooth Flow and Smart Automation

The process begins with a side transfer infeed conveyor, which receives bottles in single file from upstream equipment. From there, the product is smoothly redirected through two 90-degree infeed conveyors, orienting the bottles in the opposite direction and transferring them to the flood feed conveyor. This flood feed ensures a steady stream of bottles moves toward the bundling section without interruptions.

Next, bottles enter the staging mechanism, where an oscillator and a precise clamp-and-gate system configure them into organized bundles. The bundles are transferred onto the flybar conveyor, where they are gently pushed across the film feed deadplate by the flybars. This mechanism ensures each group of bottles stays in place and aligned as it enters the film section.

Film is dispensed through the film cradle and film feed section, which includes a splice unit for fast film roll changes and print registration for precise placement. The wrap arm then applies the film around each bundle while the transfer conveyor moves them forward at a consistent pace.

Once wrapped, the bundles are carried through a shrink tunnel via the tunnel conveyor, where a carefully controlled combination of heat and airflow creates tightly sealed, tamper-evident packaging. Finally, products exit onto the discharge conveyor, where labels are applied before the bundles are transferred to downstream equipment.

Throughout the installation and training process, the Polypack team worked closely with 3 Springs Water to ensure every detail was addressed. From the first contact to final handoff, the focus was on precision, support, and long-term reliability.

“From the start of the project, the team at Polypack has been exceptional. They truly care about the customer and go above and beyond to make sure every request is handled with care and precision. The technicians who came on-site were professional, efficient, and incredibly thorough. The team has been very helpful and methodical in training my crew. Everything was done right the first time, which is a hard quality to find in a Tech these days. What really sold us on the machine was the service department. They supported us with our old equipment in ways no other company ever has, and that commitment made all the difference. I would highly recommend Polypack to anyone.”— Joe Sokolowski, Plant Manager, 3 Springs Water

Meeting Today’s Demands with Confidence

The TangoII-24L system is now a critical part of 3 Springs Water’s production line, ensuring efficient, consistent, and scalable shrink wrapping for their bottled products. With smart engineering and a service-first approach, Polypack helped 3 Springs automate with confidence and peace of mind.
