Poly(L-lactide) Infrared Spectrum：Among them about 1250cm-1 C-O-C asymmetric stretching vibration peak, about others C-O-C symmetric stretching vibration peak, around 1750 cm-1 for the carbonyl absorption peak, 3500cm 1 about - Oh absorption peak, and 2890cm-1 2960cm-1 for and CH3.
■ According to biodegradable materials,in order to ensure product quality,a special package to aviod water is very neccessary.
■ We filled high qurity dry nitorgen in the Polyethylene bag for hot plastic, the outer lining of thermal plastic foil pouch, built-in desiccant. All the packing is done in a highly clean room.
■ All of the polymers should be stored at 0 ° C or less, and should prevent hydrolysis. Before opening, the product should be allowed to adjust to room temperature to avoid condensation polymer concentrate combined with moisture in the bag. To re-opened after the product packaging sealing, must be of high purity dry nitrogen filled to prevent moisture generated in the bag.
