Dow launches INNATE resins for liquid packaging, and stand-up pouches
Dow Chemical Company’s Packaging and Specialty Plastics business has launched INNATE Precision Packaging Resins, for flexible food packaging such as pouches, bags, liquid packaging, and stand-up pouches.

The resins combine a patented molecular catalyst with process technology for scientists to control resin properties that it claims allows for more sustainable packaging that doesn’t compromise on performance. 

The need for more sustainable food packaging

Diego Donoso, business president, Dow Packaging and Specialty Plastics, Dow, told BeverageDaily, it created the resins after analysis of market trends and discussions with brand owners and converters, which, identify the need for more sustainable food packaging.

They address some of today’s more challenging packaging performance gaps with a balance of toughness and stiffness in combination with tear and puncture resistance, he said.

The product was named “INNATE” because it has innate characteristics ie raw talents or special abilities.

INNATE resins were developed as a result of many discussions with converters and brand owners and careful analysis of the market trends​,” said Donoso.

We’re excited about what INNATE will enable in future packaging design​.”

Film stiffness, toughness and 'processability'

David Parrillo, global R&D director, Dow Packaging and Specialty Plastics, added the chemistry behind the resins allows customers to control the properties to create performance through a combination of film stiffness, toughness and processability, all from one packaging resin.

He said the INNATE resins will create categories for everything from flexible food packaging to heavy-duty industrial shipping sacks because they offer light-weighting, material substitution, up to twice the abuse resistance in co-extruded films compared to tested standard polyethylene resins on the market, film toughness and processing ease with bubble stability.

The INNATE resins give flexible food packaging applications film stiffness for efficient filling, displaying, and storing of packages like stand-up pouches; improved toughness in combination with excellent flex crack resistance for liquid packaging as well as package integrity for excellent shelf life, helping keep foods protected longer to reduce food waste​,” he said.

It has excellent processability for large diameter bubbles without blending and the resins have shown high melt strength for bubble stability and more shear thinning to enable lower amps and melt temperatures​.”

According to Donoso, Dow is always listening to customers and other partners in the value chain as well as keeping up with the trends in today’s marketplace.

Through this research and collaboration, we learned there are some performance gaps that needed to be addressed. These include things like light weighting, food preservation, sustainability and processability​,” he added.

INNATE resins address many of these gaps and can help converters meet new performance requirements​.”
