Inner is plastic bag and outer is sealed vacuum aluminumplating bag. Generally 10gram/bag and 100gram/bag are provided. Customer's special requirement are also available.2 ,Lactide TransportRefrigerated transport are preferred. Under normal circumstance, logistic and express also work. During transportation, the friction between bags can make damage to the AL-plated bag and make the seal invalid.3, Lactide StorageKeep in the vacuum environment under 4°C;or refrigeration storage. Avoid keeping the bag open in the air and storage in room temperature to prevent its hydrolysis.4, Abnormal Lactide Good lactide is dry white crystal. And when there is hydrolysis, pastiness will appear. We suggest that treat the abnormal lactide with ethyl acetate before use.5 ,Kindly remind Please check at the receiving and if there is abnormal situation, keep us informed in 5 work days. Or the lactide will be recognized accepted by the customer.
