Variable-Gauge Plastic Drawstring Bag

An apparatus comprising:

• a plastic sheet having a left portion with a left thickness and a left length, a left-center portion with a left-center thickness and a left-center length, a center portion with a center thickness and a center length, a right-center portion with a right-center thickness and a right-center length, and a right portion with a right thickness and a right length;
• wherein the left-center thickness and the right-center thickness are approximately equal;
• wherein the left thickness, the center thickness, and the right thickness are approximately equal;
• and
• wherein the left-center thickness and the right-center thickness are less than the left thickness, the center thickness and the right thickness.

A method comprising:

• a) extruding polyethylene using a die, wherein a cross-section of the die has an approximately circular shape with first large opening section, a second large opening section, a third large opening section, a fourth large opening section, a first small opening section, a second small opening section, a third small opening section, and a fourth small opening section;
• wherein the first small opening section is between the fourth large opening section and the first large opening section, the second small opening section is between the first large opening section and the second large opening section, the third small opening section is between the second large opening section and the third large opening section, and the fourth small opening section is between the third large opening section and the fourth large opening section;
• b) producing a plastic sheet from the polyethylene having a left portion with a left thickness and a left length, a left-center portion with a left-center thickness and a left-center length, a center portion with a center thickness and a center length, a right-center portion with a right-center thickness and a right-center length, and a right portion with a right thickness and a right length;
• wherein the left portion results from extrusion through the first larger opening section, the left-center portion results from extrusion through the first smaller opening and the third smaller opening, the center portion results from extrusion through the second large opening section and the fourth large opening section, the right-center portion results from extrusion through the second small opening and the fourth small opening, and the right portion results from extrusion through the third large opening section.
