METHOD FOR PACKING CRYSTALLIZED ACRYLAMIDE

PURPOSE:To secure stabilization of the quality for a long period of time by using as a packing material an inner sack of an air-permeable film or nonwoven fabric and by using a drying agent as filling between the inner sack and an outer sack having a gas-barrier property. CONSTITUTION:Crystallized acrylamide is packed in an inner sack of a moisture- permeable wrapping material such as an air-permeable film or nonwoven fabric. The resulting pack is packed with an intermediate sack of a material having a gas-barrier property and being impermeable to water vapor in air putting a drying agent therebetween. The pack is packed on the exterior side with a packing material such as ordinary multiply kraft paper. Examples of materials applicable to the inner sack are an air-permeable film or nonwoven fabric and a sheet made from polyethylene fibers. For the drying agent a product for packs, such as silica gel, or a like product is applicable; such a drying agent contained in a cloth sack, a container having fine pores, a sack of nonwoven fabric, or the like is used. This constitution makes it possible to prevent moisture in the crystallized product in a pack from undergoing condensation at the interior surface of the inner sack due to changes in temperature during transportation or storage or the like.
