No. Viscosity is just one of the many parameters of hot melt adhesive. Blindly pursuing high viscosity can lead to problems such as overflow, penetration, and difficulty in cleaning. Choosing particles depends on “matching”, not on a single number.

| Scene | Viscosity orientation | reason |
|---|---|---|
| Book and magazine adhesive packaging | Medium to high viscosity | Penetrating paper fibers, preventing falling pages |
| High speed sealing box | Medium viscosity and fast solidification | Balancing speed and initial adhesion |
| tissue paper | Low viscosity | Anti penetration glue damage literal |
Q: Does high viscosity make it stick firmly?
Answer: Not necessarily, excessive high viscosity can cause glue overflow and make it difficult to apply evenly.
Q: How do I know what viscosity to use?
Answer: Ask the manufacturer by paper type/box type/model, Sunlife hot melt adhesive provides parameter combinations.
Q: Can viscosity be adjusted on site?
Answer: It mainly depends on the model selection, and the temperature is only fine tuned for fluidity.
I’m not sure about the selection, Guangzhou Sunlife Trading will match the viscosity scheme of Sunlife hot melt adhesive according to your production line.
Not all cardboard boxes are standard rectangles The e-commerce and retail industries are increasingly using irregular cardboard boxes (such as hexagonal boxes, drawer boxes, and top and bottom covers), and the sealing and gluing path is much more complex than standard unboxing. Here are 5 common types of irregular box shapeshot melt adhesive pelletsGlue application […]
The terms “back glue” and “edge glue” are often heard in book and magazine packaging, but many people cannot distinguish whether it is the same glue with a different name or two completely different glues? Choosing the wrong one not only wastes money, but also directly leads to loose pages and cracked covers. Below, using […]
In the book printing and binding industry, hot melt adhesive is the core auxiliary material that determines the quality, environmental protection level, and compliance of books. Many printing and binding factories encounter these problems: new books that have been left out of the factory for a long time turn yellow and peel off, pages crack, […]
