Renewable Lightweight Coffee Pouches

The move to conventional flexible packaging began some time ago for many premium gourmet makers of ground coffee and coffee beans with some every day instant coffee brands mirroring this trend. Many of these lightweight packs are stand-up bags or pouches with some using vacuum packed blocks.

Renewable Coffee Pouches

Innovia Films, a leading innovator in filmic solutions for packaging, has developed a range of cellulose-based films that when laminated together with other bio materials, can provide a fully renewable filmic structure suitable for renewable coffee pouches - NatureFlex^TM.

"Coffee producers are moving towards renewable packaging which weighs less to save on transportation costs in the supply chain and to lower the product's carbon footprint," expressed Innovia Films Neil Banerjee, Market Developer - Cello.

He continued "NatureFlex^TM films offer a viable alternative to coffee producers who want a complete packaging structure that is lightweight and able to not only protect their product but at the same time is also compostable and made from renewable resources. This is the real point of differentiation for NatureFlex^TM as existing laminate structures for lightweight coffee packaging can be difficult to dispose of except through landfill, whereas NatureFlex^TM can be composted."

Typical comparison of conventional versus NatureFlex^TM film structures:

Existing Structure

Flexible packaging for the roast and ground coffee and coffee bean market typically consists of a laminate structure made up of three layers:

1. A reverse printed outer layer: 20μm BOPP or 12μm PET
2. A high barrier middle layer: 6-10μm Aluminium foil or 12μm metallised PET
3. An inner sealant layer: 50-90μm Polyethylene

The NatureFlex^TM Solution

Innovia's NatureFlex^TM films can be combined with other biopolymers by a converter, to produce a renewable alternative to the above structure.

The comparison properties are highlighted in the graph below:

NatureFlex^TM films comply with standards for compostable packaging, including EN13432, AS4736 and ASTM D6400. Depending on the individual films selected, the finished laminate structure could be certified compostable to the same standards subject to appropriate ink, print design and adhesive choices. If required, the pouches can be vented or a fully compostable zip closure could be added.

Neil Banerjee explained "We are happy to work with coffee manufacturers to ensure that they get the right laminate structure to protect their product all they need to do is contact us."
