Abstract:
1. A method for increasing the contained volume and the rate of outgassing of volatile corrosion inhibitor or antistatic material or both in a plastic bag comprising: extruding a plastic tube in a continuous extrusion process from raw material having therein volatile corrosion inhibitor or antistatic material or both with a series of spaced apart parallel longitudinal ribs on the inside of the tube; forming after said extruding step a layflat bag having two adjacent flat sides and heat sealing across the two adjacent sides to define a closed bottom end of the bag and separating said bags proximate the heat seal to define an open top end of the bag such that the total volume and total surface area of the inside of the bag is greater than it would be without ribs thereby increasing the contained volume and rate of outgassing into the bag interior of volatile corrosion inhibitor or antistatic material or both contained in the plastics; such that the total volume and total surface area of the inside of the bag is greater than it would be without ribs thereby increasing the contained volume and rate of outgassing into the bag interior of volatile corrosion inhibitor or antistatic material or both contained in the plastic.
