ABSTRACT:
A packaging system including novel and improved packaging apparatus, packaging webs, and packaging methods having particular utility in the packaging of powder, granular and other fluent materials. The improved apparatus includes a movable loading chute which extends into a bag positioned in a loading station to funnel materials into the bag. The loading chute is guided by a cam during extension into the bag to assure that it properly enters and opens the bag. The bag is only partially opened by the entering loading chute and a seal is formed between the bag and the chute to prevent the escape of powder, etc. around the chute.
The packaging system is operable with existing packaging webs and with an improved packaging web which is partially sealed to define a restricted fill opening. After the bag is filled, the seal is completed across the fill opening, preferably at a location spaced outwardly from the contents of the bag.
Other features, including a vacuum system for evacuating air from loaded bags, are disclosed together with packaging methods utilizing the improved apparatus and packaging webs.
