Films|Flexibles|Bags A lightweight coffee pouch made from renewable resources using NatureFlex from Innovia Films. Renewable Lightweight Coffee Pouches Today metal cans, glass jars and rigid plastic containers dominate instant coffee packaging, all of which are recyclable but none are made from renewable resources or offer compostability. 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. 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 coffee pouches – NatureFlex. “Coffee producers are moving towards 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 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 as existing laminate structures for lightweight coffee packaging can be difficult to dispose of except through landfill, whereas NatureFlex can be composted.” Typical comparison of conventional versus NatureFlex 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 (biaxially oriented PP) 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 Solution Innovia’s NatureFlex 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: Thickness / µm 100 90 80 70 60 50 40 30 20 10 PET, 12 µm Aluminium Foil, 7 µm Polyethylene, 60µm NatureFlex 20N Printable, transparent barrier NatureFlex 20N921M Metallised high barrier layer Bio-Polymer sealant layer High seal strength and integrity PET, 12 µm Metallised Polyester, 12 µm Polyethylene, 60µm Clear NatureFlex NK, 20 µm Metallised NatureFlex, 20 µm Biopolymer Sealant, 50 µm 0 Standard Packaging 1 Standard Packaging 2 NatureFlex based Bio-Laminate NatureFlex 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.” www.innoviafilms.com 32 bioplastics MAGAZINE [06/11] Vol. 6

Order now! A new study from The Freedonia Group, Inc. Degradable Plastics Book-Review Bookstore The degradable plastic industry has been on the verge of commercial success for decades. However, demand growth was limited because most degradable plastics were too expensive, were unavailable in large enough quantities or had performance drawbacks that limited them to niche markets. This situation began to change in the early 2000s, as interest in environmentally friendly products gained strength, boosted by the efforts of major users like Wal-Mart. At the same time, the availability of biodegradable plastics increased significantly due to expansions by key producers. These and other trends are presented in Degradable Plastics, a new study from The Freedonia Group, Inc., a Cleveland-based industry market research firm.

It is obvious that you went to great lengths on this work. You have listed biopolymers I haven‘t even heard of. This report will be very helpful to all involved in the biopolymer world.“ A reader‘s remark Hans-Josef Endres, Andrea Siebert-Raths Engineering Biopolymers Markets, Manufacturing, Properties and Applications 660 pages, hard cover. 278 coloured pictures, 70 tables Reduced Now available Price ! Author: Jan Th. J. Ravenstijn, MSc The state of the art on Bioplastics, January 2010 The report ‘The state-of-the-art on Bioplastics 2010‘ describes the revolutionary growth of bio-based monomers, polymers, and plastics and changes in performance and variety for the entire global plastics market in the first decades of this century. Trends, issues, technologies, products, markets, manufacturers, investment plans, performances, needs, expectations, and new opportunities are reviewed and discussed. This includes the assimilation of the agricultural industry with the polymer industry to a new value chain. Today, bio-based thermosets are larger than bio-based thermoplastics, while also the volume of bio-based durable materials exceeds the volume of bio-based biodegradable plastics.
