Metalized BioPBS™ film development – a journey to become a leader in compostable films

According to the United Nations Environmental Program (UNEP), 1.3 billion tons of food is either lost or wasted yearly across the world. With world hunger on this rise due to the COVID-19 pandemic, the need to reduce food waste is becoming increasingly urgent. In addition, food loss and waste contribute to the three global crises that threaten our future – climate change, biodiversity loss, and pollution.

Guidelines issued by UNEP and the Institute for Global Environmental Strategies (IGES) show the practice of composting is one of the best options for managing organic waste while also reducing environmental impacts. This is being underlined by the publication prepared by Sustainable Packaging Coalition that compostable packaging should not be treated as a blanket solution. When used in the right applications, compostable packaging can create a simplified consumer dining experience and serves as a solution for non-recyclable packaging. More broadly, compostable packaging can be part of healthy biological loops in the circular economy where food waste is being diverted from landfills, resulting in reducing Green House Gas (GHG) and contributing to compost that helps recover soil fertility.

As for non-recyclable packing, it is linked to multi-layer flexible packaging that is in contact with food and it is difficult to recover the packaging for recycling due to complexity of multi-material structure, limited capability of infrastructure to recover the materials as well as the availability of store drop-off for collection that is being limited relatively. Based on these trends and study, compostable solution is being served crucially as a promising option to help companies and brands meet their packaging goals.

PTT MCC Biochem Company Ltd. (PTTMCC) is a manufacturer of Polybutylene Succinate, which is plant-derived biodegradable and compostable plastic under trademark “BioPBS™”.  BioPBS™ has excellent low-temperature heat-sealing properties and flexibility and is being applied for compostable flexible packaging for a wide range of dry food products, such as coffee bean, coffee powder, tea, biscuit, organic powder and much more.

In response to high barrier property requirement of oxygen and moisture by end market in flexible packaging in order to meet expected performance for conventional structure, PTTMCC has been developing metalized BioPBS™ film with strategic converter – Kimpai Flexible Packaging Company with an aim to offer new generation of home compostable sealant film that can provide excellent sealability and high barrier property at the same time.  With this new development, it would create more endless opportunity for adoption by brands who seeks for sustainability goal in flexible packaging without sacrificing functionality.
