Description / Application / Shipment and storage / Risk factors
Plastic materials which become contaminated with dust, dirt, etc., may, if such foreign matter cannot be separated, become useless for the production of high-grade articles. When this material is in dried form, moulding powders, etc., and is packed in paper bags, it is particularly liable to depreciation by reason of the bags coming into contact with foreign substances. Care is necessary in handling damaged bags to avoid contamination of the unexposed portion of the contents. The following are individual comments on various plastic materials for guidance in assessing the cause and extent of damage, and in the handling and treatment of plastic materials:
