Method for unitizing containers

A method of unitizing a plurality of boxes comprising the steps of:

• sealing the top and bottom of each box with a linerless double-backed adhesive tape structure having a first tape strip with adhesive on one side thereof and second and third tape strips each having an adhesive on one side thereof, said second and third tape strips overlapping said first strip along the edges of said first strip with said adhesive sides of said second and third steps facing said adhesive side of said first strip thereby joining said strips together with an exposed adhesive side of said first strip facing in an opposite direction to an exposed adhesive side of said second and third strips, said exposed adhesive sides of said second and third strips being adhered to the box;
• and
• stacking the boxes on one another with said exposed adhesive surface of said first tape strip on each box joined and adhered to at least a portion of said exposed adhesive surface of said first tape strip on an adjacent box.

A method of unitizing a plurality of containers comprising the steps of:

• placing on a surface of each container a single-sided adhesive tape having an adhesive coated side and an adhesive free side with the adhesive coated side adhering to said surface;
• folding at least one lateral edge of said tape to expose a portion of the adhesive coated side;
• stacking said containers together with said exposed portion of said adhesive surface of said tape being adhered to a surface of an adjacent container.

A method of sealing and unitizing a plurality of boxes comprising placing on the top of each of said boxes a linerless double-backed adhesive tape structure having a first tape strip with an adhesive on one side thereof and second and third tape strips each having an adhesive on one side thereof, said second and third tape strips overlapping said first strip along the edges of said first strip with said adhesive sides of said second and third strips facing said adhesive side of said first strip thereby joining said strips together with an exposed side of said first strip facing in an opposite direction to an exposed adhesive side of said second and third strips, and aligning said tape structure on the top whereby said second or third tape strip seals the top,

• sealing the bottom of each of said boxes with a single sided adhesive tape,
• stacking said boxes on one another with said exposed adhesive surface of said first tape strip on the top of each box adhered to the bottom of an adjacent box at a location spaced apart from said single sided adhesive tape.

A method of unitizing and sealing a plurality of containers comprising:

• placing on each of said containers a double-backed adhesive tape structure having a first strip portion for providing one exposed surface with an adhesive thereon and a second strip portion for providing a second adhesive coated surface that is adhered to said container for sealing said container;
• stacking said containers together with the exposed adhesive surface of said tape structure on each container being adhered to at least a portion of the exposed adhesive surface of said tape on an adjacent container.
