Answering the industry needs of high performance, consumer convenience, and recyclability, Dow has announced an innovative brand extension to the family of Innate precision packaging resins. Innate TF polyethylene resins for tenter frame biaxial orientation are bringing commercial viability to a long-desired packaging goal – Tenter frame biaxially oriented polyethylene (TF-BOPE) films. Compared to traditional polyethylene (PE) films, the TF-BOPE film made with Innate TF Polyethylene Resins for Tenter frame biaxial orientation, according to Dow, has higher mechanical properties and material rigidity, better optical and printing performance. It offers considerable sustainability advantages, including the potential for all-PE structures for recyclability.

TF-BOPE films made using Innate TF resins demonstrate many properties valued across the value chain – optical properties such as transparency and glossiness; up to 80% less haze compared to traditional PE films; twice the impact strength and tensile modulus; three times the puncture resistance and tensile strength of traditional blown PE films; flex crack resistance, even under low temperature; and good tearability for convenience-in-use.

Sustainable packaging solution

Innate TF Polyethylene Resins for tenter frame biaxial orientation offer distinctive physical properties which can enable material substitution, film layer elimination, or downgauging, to reduce overall packaging materials.

According to Dow, the TF-BOPE film can be used directly as the printed layer of the packaging, allowing a combination of PE functional layers to achieve an all-PE structure, making it convenient for recycling and increasing the sustainability quotient.

Applications are already on the shelf

Collaborating with a variety of value chain members, such as Guangdong Decro Film New Materials, CaiHua, NanCheng, and KAIDA Group, commercial applications – including all-PE pillow pouches, recyclable SUP packaging, and liquid product SUPs – are now in the marketplace.

Applications include rice bags, pet food bags, heavy-duty shipping sacks, liquid detergent pouches, and others. Case studies regarding some of these applications are available for review.

Asia Pacific marketing director for Food & Specialty Packaging, Dow Packaging and Specialty Plastics, Kodak Xiao, stated, “As one of the leading materials solutions providers to the packaging industry, Dow hopes to collaborate with key stakeholders across the value chain to promote innovative and sustainable packaging solutions, and promote the healthy and dynamic development of the industry. With its downgauging and recyclability potential, Innate TF resins already offer answers to the plastic waste issue, and we believe more advantages can be found together.”

These successes come after more than a decade of effort. According to Wu Chang, Asia Pacific director for Technical Services and Development (TS&D), Dow Packaging and Specialty Plastics, “Our Asia-Pacific regional R&D team engaged in intensive research into the future trends of the packaging market. This revolutionary product breaks through the limits of traditional PE products and showcases Dow’s futuristic and cutting-edge insights, as well as our strong R&D capacity.”

Since the initial release in 2017, Dow’s TF-BOPE resins have earned three prestigious awards – an Edison Awards Gold, an R&D 100 Award, and the Ringier Technology Innovation Award.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.
