BAG AND METHOD FOR PACKAGING GRANULAR COMPOUNDS

摘要

A bag and method for packaging granular compounds and especially dust-prone, lead-based stabilizer compounds. The bag (10) is preferably formed from a thermoplastic film, such as low molecular weight ethylene vinyl acetate copolymer (EVA) film which is initially sealed around substantially its entire periphery (16, 18, 20, 22) prior to filling the bag (10) with the lead-based heat stabilizer compound (36). The bag (10) includes a relatively small diameter spout portion (26) extending outwardly from a main body portion (12). The spout portion (26) is sealed except for an open end (28) through which the bag (10) may be filled with granular compound (36) by a filling tube (32). The end of the spout portion (26) includes a cuff (31) which is folded back onto the spout portion (26) to prevent contamination thereof with the granular compound (36). When the cuff (31) is unfolded, a heat sealable area is defined between an outer edge (28) of the spout portion and a discretely formed fold line (30).
