Established in 1998, located in Zhejiang Industrial Park on the upper reach of Fuchunjiang River, Tonglu Aoer Stationery Co., Ltd. is a fast growing manufacturer and supplier of a wide range of ball pens, gel pens, highlighters and other plastic products. Since the year of 2007, Tonglu Aoer Stationery Co., Ltd has been engaged in the application of a new biodegradable material which is called polylactide (PLA). Now, we have already successfully used this material to produce pens. We use annually renewable plant resources (corn) as raw material, which is fermented and distillated to produce lactic acid. Following by the process of dehydration polymerization, high-temp depolymerization, refining, and final polymerization, lactic acid is then transformed to PLA. This material can be decomposed through composting after used and is considered to be the most promising biodegradable plastics in
