1. A method for increasing the contained volume and the rate of outgassing of volatile corrosion inhibitor in a plastic bag comprising:
extruding the plastic bag in a continuous extrusion process from raw material having therein volatile corrosion inhibitor with a series of spaced apart parallel longitudinal ribs on the inside 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 contained in the plastic;
forming in said extrusion process 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.
2. The method of claim 1 further wherein said ribs are spaced apart from about 0.200 inch to about 0.750 inch.
3. The method of claim 2 further wherein said ribs have a height from about 0.020 inch to about 0.060 inch.
4. The method of claim 1 wherein the ratio of the distance the ribs are spaced apart to their height is from about 3:1 to 10:1.
5. The method of claim 1 wherein the ratio of the rib width to the rib height is from about 3:1 to 1:1.
6. The method of claim 1 further wherein said ribs are generally rounded in shape.

18. A method of increasing the contained volume and the rate of outgassing of volatile corrosion inhibitor in a plastic bag comprising:
providing an extrusion die having recess elements to form a series of spaced apart longitudinal ribs in the interior of plastic bags formed by such die;
extruding plastic bags from said die in a continuous extrusion process from raw materials having therein volatile corrosion inhibitor said plastic bags formed by said die having a series of spaced apart longitudinal ribs in the interior of the plastic bags formed by such die such that the total volume and total surface area of the inside of the bag is greater than it would be without ribs;
forming in said extrusion process 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;
whereby the longitudinal ribs provide increased volume to increase the contained volume of volatile corrosion inhibitor in the bag and the longitudinal ribs provide increased surface area in the bag interior thereby increasing the rate of outgassing into the bag interior of the volatile corrosion inhibitor contained therein.
19. A method of protecting electronic devices stored in a plastic bag comprising;
extruding the plastic bag in a continuous extrusion process from raw material having therein volatile corrosion inhibitor with a series of spaced apart parallel longitudinal ribs on the inside 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 contained in the plastic;
forming in said extrusion process 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; and
inserting an electronic device inside the plastic bag.
