INTRODUCTION More environmental protection requirements force users of solvent-based coating to look for an environmentally safe procedure which emit considerably less solvents or cracked products into the atmosphere and water. Also the new EC Super directive regarding migration of less then 10 ppb into the food will force the packaging producer to look for new technologies. [28] The chemistry has new groups of products to offer: - System with low content of solvents and with high solid contents - coating material containing water - coating with solid resin in powder form - 100 % solid system.
