UFlex partners with Hoffer Plastics, Mespack, to bring recyclable monopolymer bags to the market

UFlex has partnered with Mespack, an international manufacturer of flexible packaging, end-of-line and soluble capsules for consumer goods companies serving the world’s leading brands, and Hoffer Plastics, an industry leader and innovator in the custom injection molding industry. Develop a sustainable solution that eases the complexities of recycling associated with hot fill bags.

In order to tackle the problem of bags being completely recyclable, the three titans have jointly developed a turnkey solution that, with its new monopolymer structure, not only enables hot-fill bags to be 100 percent recyclable, but also the spout caps, bringing many ecologically responsible brands closer to one another to achieve their sustainability goals.

Typically, hot fill bags are used to package ready-to-eat food segments, which allow sterile packaging of a range of fresh, cooked or semi-cooked foods, juices and beverages and are used as an alternative to traditional industrial canning methods. The benefits of hot fill bags have exceeded consumer expectations due to the functionality of easy storage and direct consumption of the food contents after heating in the package itself.

The newly developed, recyclable, PP-based hot fill bag made from a single material combines the strength of the layered OPP and CPP laminate structure developed by UFlex and offers improved barrier properties, easy heat sealability and longer shelf life for unrefrigerated food storage; sealed with patented closures from Hoffer Plastics in the form of tamper-proof, strongly sealing spout caps; and manufactured with the mechanical integrity of the Mespack HF series fill and seal machine, which enables efficient filling through the spout of pre-made bags.

The new design offers 100% easy recyclability of the laminate and pouring cap, as well as within existing PP recycling streams and infrastructures. Manufactured at the UFlex India factory, these bags are exported to American markets and used for packaging edible products such as baby food, food puree, pet food, etc.

Thanks to the Mespack technology, the HF series is completely developed and constructed to work with recyclable materials, and the continuous filling through the spout reduces up to 15% of the head space by eliminating the wave effect.

“With our future-proof approach, which focuses on circular packaging, we try to offer products that expand our sustainable footprint in the ecosystem,” said Luc Verhaak, Vice President Sales at UFlex Packaging. “The mono-material design, like this recyclable PP hot-fill spouting bag, creates added value for the recycling industry and helps build a better recycling infrastructure. This joint creation with Mespack and Hoffer Plastics is an achievement that is supported by a shared vision for a sustainable future and excellence in packaging, and it also marks the beginning of new possibilities in the future that can be tapped with our respective strengths. “

“One of our Mespack promises is to focus on developing innovative equipment for sustainable packaging solutions to protect the environment and reduce the carbon footprint,” said Guillem Clofent, Managing Director of Mespack. “To do this, we are pursuing three main strategies – reducing the use of raw materials, replacing them with recyclable solutions and adapting our technology to these new recyclable, biodegradable or compostable materials. In this case, thanks to the collaboration between key strategic partners, our customers already have a recyclable solution for pre-made bags that contribute to the circular economy while helping to achieve their goals.

“Sustainability has always been a critical focus and driving force at Hoffer Plastics,” said Alex Hoffer, Chief Revenue Officer at Hoffer Plastics Corporation. “More than ever, products that are completely recyclable and cycle-oriented from the start are not only in demand, but will shape the future of our industry and the environment. We pride ourselves on working with innovative, responsible partners like the UFlex and Mespack teams to lead the way forward. “
