Market Backgroud

Flat rope paper bags and small batch orders stil rely on pure handmade production;
Most of the paper bag processes on the market are side edge sealing + bottombonding, and the bottom is the main stress-bearing part of the paper bag, which easilyleads to bottom degumming;
When the bag is folded flat, there is a waistline on the front and a waistline with largecharacters on the side. The bottom is multi-loyered and the lines are complicatedwhich destroys the integrity of the paper bag and the printed pattern;
There is no bonding on the inside of the bag opening, and the inside is elastic, whichaffects its use.
