How to choose low odor for hot melt adhesive particles with strong odor? These 5 misconceptions to avoid

Smell is not a small matter

Book and magazine factories, graphic and text stores, food packaging workshops,Hot melt adhesive granulesOdor directly affects worker comfort and customer perception. But the typical misconception is that ‘strong odor equals firm adhesion’, and there is no necessary relationship between the two.

5 common misconceptions

• Misconception 1: The stronger the odor, the more sticky it is. Wrong, the adhesion comes from the resin and viscosity, not the odor.
• Misconception 2: Having an odor is toxic. Not necessarily, it depends on whether it has passed RoHS/food contact testing.
• Misconception 3: You can judge good or bad by just smelling with your nose. Wrong, you should refer to the VOC testing report.
• Misconception 4: Low temperature makes it tasteless. Low temperature only slows down volatilization, the formula itself is the root cause.
• Misconception 5: All low odor adhesives are expensive. Choose the right brand, and the bulk price is controllable.

Correct selection method

Request a third-party low odor/low VOC testing report from the supplier and conduct a small sample test on your actual equipment: after heating to working temperature, smell the emitted odor and check the workshop feedback. Sunlife Hot Melt Adhesive’s Guangzhou Sunlife Trading provides low odor books, magazines, and packaging models with testing data, suitable for odor sensitive stores and food lines.
