Where Do Paper Bags Come From? A Brief History

Who Invented Paper Bags?

The origins of the modern paper bag date back to 1852, when Francis Wolle, an American schoolteacher, patented the first machine to mass-produce envelope-style paper bags. Later, in 1871, Margaret E. Knight revolutionized the industry by inventing the flat-bottom paper bag, making it far more practical for everyday use.

By 1883, Charles Stilwell developed the “self-opening sack” (SOS) bag—an upright, stackable version that still influences designs today.

Fun fact: Plastic bags weren’t introduced until the 1960s, meaning paper had already dominated for decades. (Source: Smithsonian Magazine)

Step-by-Step Paper Bag Production Process

At modern paper bag factories, the process has become highly automated and efficient. Here’s how paper bags are made:

1. Raw Material Selection
   
   
   • Most bags use kraft paper, made from virgin or recycled wood pulp.
   • For moisture resistance, some bags use laminated kraft paper.
2. Paper Cutting: Paper rolls are cut to precise dimensions based on the bag’s intended size.
3. Folding & Gluing: Machines fold the paper into the desired shape and apply adhesive to seal the sides and bottom.
4. Printing:Branding elements like logos, colors, and slogans are added using offset or flexographic printing.
5. Handle Attachment: Handles (twisted, flat, or rope) are glued on using automated systems.
6. Final Inspection & Packaging: Bags are quality-checked, stacked, and packed for shipping.

This streamlined process ensures high-volume production while maintaining brand consistency and eco standards.
