ABSTRACT:
A package is provided of wound strand of filaments coiled in layers, into a tubular configuration, with a sheet material covering of ionic polymer that has a surface attraction to the strand, for keeping the strand against the sheet material or film during unwinding of the strand from the package, completely through to the end of strand removal from the package. Electrostatic charge is induced on the strand and sheet material, to create electrostatic attraction at their common interface, for holding the strand to the sheet material and preventing the last portion of a strand package that is being unwound, from becoming tangled. Accordingly, this electrostatic attraction causes the film to support the outer strand coils in the package as the strand is withdrawn from the package, thereby preventing coils from slumping or falling together and becoming tangled.
