An improved instrumentation and method for manufacturing from film wrapping material hermetically sealed packages containing an untangled, unknotted segment of flaccid filament, and packages produced by the instrumentation and method. Instrumentation improvements include a gripper assembly for impeding uncut filament from backing up during filament loading in the course of package construction, an improved piston also impeding filament backup and facilitating deposition of a filament segment into an open package compartment, and a sealing mechanism for superimposing a seal over the top and bottom package seals.
