Looking Ahead to New Packaging Material Innovation

Packaging engineers and product developers must work together to create new sustainable initiatives in packaging material innovation.

One of the UN sustainable development materials goals, according to a new report by PMMI Business Intelligence, is to increase the share of responsibly sourced, renewable content, to at least 75%.

Suppliers recognize that resin content is a key component to future material innovation, and according to one VP of Technical Excellence and Innovation at a material supplier, “We need to improve our material selections from resin suppliers and use more post-consumer recycled content to offer a more diverse product portfolio.”

Polymers:

·     Polypropylene (PP) is a versatile material demonstrating reliable barrier properties. High performance PP grades can often be used in place of polyethylene.

·      Polyethylene (PE) is a mono-material structure, meaning that it is naturally more recyclable than multi-material composites. PE often fails to provide adequate barrier protection, however.

·      Polylactic acid or polylactide (PLA) is a fully biodegradable thermoplastic polymer consisting of renewable raw materials for direct food contact compliance (USA and EU).

·      PHAs (polyhydroxyalkanoates) are bio-based, biodegradable, and have a wide range of potential applications, given their physical properties.

·      Bio-based PE and bio-based PET, as well as bio-based polyamides, make up a large portion of the global bioplastics market, accounting for 44% (1.1 million tons) of all bio-based plastics.
