A gift paper bag processing workshop in Guangzhou can produce 2000 handmade paper bags per day, using white milk adhesive at the bottom. The humidity in the southern region is high, causing slow curing and low initial adhesion of white latex. Even after workers have glued the bottom and left it for 2 hours, 30% of the adhesive still needs to be reworked, resulting in extremely low efficiency. Customer reminders are causing headaches.
Under the recommendation of peers, Sunlife hot melt adhesive was found. After on-site inspection, the engineer recommended fast curing EVA hot melt adhesive particles with an opening time of 1.5 seconds and high initial adhesion, which can be applied with a small glue gun. First week trial production results:
Although the unit price of hot melt adhesive particles is about 40% higher than that of white latex, the amount used is only one-third (coating line width 3mm vs white latex coating surface 15mm), and the overall bonding cost is actually reduced by about 15%. Guangzhou Sunlife Trading provides monthly supply and small batch minimum order, which is very friendly to small processing workshops.

The force, material combination, and equipment rhythm borne by the lifting rope, side edges, and bottom adhesive of paper tote bags are not completely the same. When choosing hot melt adhesive for hand-held bags, the spraying method, pressing cycle, paper material, and usage environment should be clearly explained first, and then the matching degree between […]
