Loopla recycling to lactic acid claims to capture embodied energy and returns the product to nature or convert it to recycled PLA. In February 2009, Fonti di Vinadio, one of Italy’s leading marketers of mineral water, launched its Santa Anna brand reference packaged in Ingeo PLA manufactured by NatureWorks. 5 litre sizes, uses a vegetable dye to colour the bottle green, in order to distinguish it from the usual PET colour of blue. The non-petroleum origin of the bottle material is marketed as an advantage, as it represents an environmental plus, and though the price per unit is higher than PET, it is lower than glass.

61mm biodegradable PP. In order for satisfactory closure of bags formed from the films to be achieved, the biodegradable PP and HDPE required the use of an impulse sealer. 7°C) and 80% relative humidity. Results indicated that improvements were needed to extend the heat seal temperature range of biodegradable films for ease of running on commercial VFFS machinery. Lincoln and York, a UK coffee roasting company, launched a new range of biodegradable packaging for its beans and blends products in June 2010.

Designed for use in food packaging, the film contains a plasticiser extracted from brine, which improves transparency and makes the plastic easier to form. Research had shown that when magnesium chloride extracted from brine used in the manufacture of tofu was added to starch used to make biodegradable plastic, it enhanced the resultant plastic’s sheet forming and hot press moulding characteristics. Sheets made with the brine were also found to have improved transparency and flexibility, together with heat resistance, hygroscopicity, antibacterial and water solubility properties.
