Why doesn't the personal chef's wonton sauce bag get his hands dirty?

1, heat sealing: put the sauce package into a heat sealing machine, and heat seal the mouth to make the seal firm and difficult to disassemble.

2. Knot: Fold the bag mouth at the sauce mouth and tie it with a rope. The seal is firm and not easy to disassemble.

3. Labeling: Fold the bag mouth at the sauce mouth and label it with adhesive tape. The seal is firm and not easy to disassemble.

4. Sewing: Fold the bag mouth at the sauce mouth and sew it with a sewing machine. The seal is firm and not easy to disassemble.
