Oxo-degradable debate | additives feature
over 90% of the finished masterbatch weight. The active ingredients are best side-fed to reduce residence time – otherwise dry-mix preparation can be used. The mixture is a combination of stabilisers and pro- degradant(s) geared to suit the final application and its service life. The masterbatch produced is introduced into the finished products at the processing stage. In most cases, the let-down ratio is 1%. Therefore the impact on processing parameters is zero. There is no need to alter line speeds or temperatures. The finished product suffers no detriment to performance in barrier properties, clarity, printability or sealability.

able plastics now offer a solution. Many supermarkets, retailers and other large
commercial users worldwide are now using oxo-biode- gradable plastic to demonstrate practical concern for the environment. There are no heavy metals used in Reverte additives and this has been independently certified. Despite the belief of some people that oxo-biodegradable plastics
