Dow and Menshen, manufacturers of caps, closures and single-serve capsules, announced reverse spout sealing technology that enables the production of spouted pouches made of mono-material films. This technology allows converters to address the recycling criteria for flexible packaging and can help brands meet their sustainable packaging goals.

“We basically reversed the idea of where and when the heat needs to be applied during the spout sealing process,” explained Peter Sandkuehler, global application technology leader at Dow’s Packaging and Specialty Plastics business. “By transferring the heat from the pre-melted spout base directly to the sealant layer of the film, we’ve solved two challenges at the same time – how to easily seal spouts to mono-material films, and how to prevent the hard spout ribs from cutting into the film,” he added.

The new process easily seals spouts in more heat-sensitive, mono-material structures made from all polypropylene or all polyethylene packaging layers. Rather than traditionally applying the heat from outside the pouch forming film to melt the seal layer and the spout, the latter is pre-melted at its base before insertion into the pouch and sealing.

“The beauty of the process is its simplicity,” said Sarah De La Mare, business development officer at Menshen. “It is actually more logical to apply the heat from the inside rather than from the outside, whether you use mono-materials or not. We are currently working with several machine manufacturers to ensure that this technology can be integrated into new and existing spouted pouches making lines.”

Reversing the traditional sealing process reduces the excess heat needed to be applied from the outside of the film to seal the inner, lower density film layers to a high-density spout base. At the same time, the packaging structure is less dependent on a film’s thermal resistance and film cut-in is avoided, resulting in good quality spout sealing and a pouch.

“At Dow, we have been working on expanding our portfolio of polyethylene-based mono-material solutions for several years. When looking at spouted pouch applications, we knew that changing this would not be an easy task and would require out-of-the-box thinking,” said Jaroslaw Jelinek, marketing manager for EMEA, Dow Packaging and Specialty Plastics. “What Dow and Menshen bring to the market today is a transformative technology that contributes to the plastic circularity goals that Dow and the entire industry have committed to,” Jelinek says. The reverse spout sealing technology is the result of a three-year joint development between Dow and Menshen who are working with a number of partners on technology integration and assist brand owners and converters to put the new sealing approach into practice. Both companies are working with leading manufacturers of pouch-packaging machines worldwide in order to commercialize the technology.

The reverse spout sealing technology was successfully tested at Dow’s Pack Studios in Horgen, Switzerland, with Menshen spouts sealed in mono or laminate film structures containing Dow solutions such as DOWLEXTM 2750ST, ELITETM 5960G in outer layers coated with OPULUXTM HGT and AFFINITYTM sealants. The technology is suitable for most pouch sizes and for a wide range of applications – from baby food, condiments and detergents, to personal care applications such as shampoos, shower gels or body lotions. For packaging applications that cannot compromise on content preservation, Dow combines this technology with barrier solutions in structures that are designed for recyclability.

Dow and Menshen at K 2019

Dow will be attending K 2019, the conference for the plastics and rubber industry, from 16 to 23 October 2019 in Düsseldorf, Germany. The event will gather the most influential and creative suppliers of machinery, parts and products under one roof. It will allow visitors to ask challenging questions, forge new relationships and start collaborations that will help transform businesses and society.

Packaging South Asia’s editor, Naresh Khanna will be covering K 2019 and can be reached through the TeamIndia@K WhatsApp group. Interested persons can join the WhatsApp group by sending their name, phone number, and company name to edit10@ippgroup.in.

Packaging South Asia — resilient, growing and impactful — daily, monthly — always responsive

The multi-channel B2B in print and digital 17-year-old platform matches the industry’s growth trajectory. The Indian, South Asian, Southeast Asian, and Middle East packaging industries are looking beyond the resilience of the past three years. They are resuming capacity expansion and diversification, with high technology and automation in new plants and projects.

As we present our 2024 publishing plan, India’s real GDP growth for the financial year ending 31 March 2024 will exceed 6%. The packaging industry growth will match the GDP growth in volume terms and surpass it by at least 3% in terms of nominal growth allowing for price inflation in energy, raw materials, consumables, and capital equipment.

The capacity for flexible film manufacturing in India increased by 45% over the past four years. With orders in place, we expect another 20% capacity addition in 2024 and 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels are growing similarly. As the consumption story returns over the next six months, we expect demand to return and exceed the growth trajectory of previous years. The numbers are positive for most of the economies in the region – and as shown by our analytics, our platform increasingly reaches and influences these.

For responsible and sustainable packaging, with its attendant regulations and compliances, there is significant headroom to grow in India and the region. Our coverage includes the entire packaging supply chain – from concept to shelf and to waste collection, sorting, and recycling.

We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers. This is a large and complex canvas – the only thing that can work is your agile thinking and innovation together with our continuous learning and persistence.

The coming year looks to be an up year in this region, and this is the right time to plan your participation and marketing communication – in our rich and highly targeted business platform with human resources on the ground. Share your thoughts and plans to inspire and mobilize our editorial and advertising teams!
