Seamless paper bags, also called “waistline-free” bags, are made by automatic machines. Unlike traditional folded bags, they are formed in one piece using hot melt glue.
The process starts with stacked sheets of paper. After machine adjustment, a single sheet passes through multiple stations and becomes a finished bag. This one-step method ensures uniform quality and faster production.
Seamless paper bags are strong and neat. They are popular for retail, gifts, and takeout. Their clean appearance gives a premium feel, making them ideal for brand presentation.
