Politics Mater-Bi

Politics Mater-Bi starch-based material. These packs now show the famous ‘Seedling’ logo, with conversion carried out by printers such as Natura A.S.P. Packaging, Amcor Flexibles & Paragon Flexibles. Marks and Spencer, who have gained prominence in the whole environmental debate through the introduction of their ‘Plan A’ scheme, (whereby they aim to be carbon neutral by 2012, and for no packaging to landfill before that date) have focused more on the drive for sustainability & renewability rather than compostability. Materials such as metallised NatureFlex (twistwrap & board lamination applications) and transparent PLA (flexible film in sandwich box windows, and rigid trays for delicatessen products such as prepared salads) can be found in store at M&S. Other retailers have followed with similar introductions and Morrisons, Tesco, Waitrose & Co-op have all introduced their first product lines. All indications are that further retail lines will follow in 2008. Increasing technical capabilities Until 2007 most Bioplastics applications in the UK were either rigid trays, unprinted or simple motifs on singleweb flexible films. 2007 saw the introduction of higher levels of specification. For instance the starch based films, which typically provide only limited levels of transparency are now printed with much more developed graphic designs. Late 2007 saw a major technical breakthrough with the launch of Jordan’s organic Muesli and Granola lines. Converted by Alcan Packaging these packs use a ‘bio-laminate’ structure. A reverse-printed transparent Nature- Flex film replaces conventional PET or OPP films for the outer ply which provides heat-resistance, barrier and dimensional stability properties. A film manufactured from Mater Bi is laminated to the NatureFlex and replaces the conventional PE film used on the inside of the pack. This film provides the required mechanical strength, tear-resistance and integral sealing properties. The structure is expected shortly to become the first certified compostable laminate solution in the market and earned Alcan the 2007 Bioplastics award for best packaging application. Marrying the properties of two totally different materials is standard practice in flexible packaging today, but this is the first example of its use on a branded product in a ‘bio’ format. Looking to the future, such concepts should allow biomaterials to extend their use beyond the short-shelf life & fresh produce categories into a much wider range of applications, in the UK and beyond...
