How to use Hot melt adhesive for book binding

1. Add the hot melt glue for book binding into the hot melt glue pot, and then set the temperature of the hot melt glue pot.
2. Preheat the hot melt glue until the glue becomes molten.
3. According to the opening time of the glue, set the binding speed and glue amount of the book binding production line.
4. After the glue roller evenly applies glue to the book, it is necessary to apply a certain amount of pressure to complete the initial curing.
5. Leave the book for a few minutes, and wait for the glue to completely cure before proceeding to the next processing step.

Hot melt adhesive for book binding application notes

1. The paper type of the book and the speed of the gluing line will affect the bonding effect. It is recommended to try it first before using it in large quantities.
2. When using hot melt adhesive for book binding, it is recommended to apply a certain amount of pressure to the bonding point so that the glue can penetrate into the bonding material well.
3. The hot melt adhesive must be seen to be molten before bonding.
4. Before using hot melt adhesive for book binding, the paper needs to be flattened to ensure that the hot melt adhesive can fully exert its viscosity.
5. The setting temperature of the glue melter should not be too high to avoid carbonization of the glue, which will affect the bonding strength of the glue.
6. The glue melt furnace needs to be cleaned regularly to avoid carbonization of the hot melt adhesive after long-term use, which will affect the bonding effect.

Hot melt adhesive for book binding FAQs

Q1.What is the best glue for book binding?

A1. For commercial book manufacturing, considering mass production and bonding performance, EVA (ethylene-vinyl acetate) hot melt adhesive and PUR (polyurethane) hot melt adhesive are the most suitable glues. For ordinary book binding, PVA (polyvinyl acetate) glue can also be used.

Q2. Why does the book binding fall off after being glued with hot melt glue?

A2.a. The open time of the glue is too short. b. The temperature of the glue is set too low. c. The thickness of the book is inconsistent. d. The bonding position of the book core is not in proper contact.

Q3. Why do pages fall off after the book is glued with hot melt glue?

A3.a. The pages are not arranged neatly. b. The amount of glue applied is too low. c. The permeability of the paper is too poor. d. There is a gap in the glue shaft. e. The glue opening time is too short.

Q4. Why does the book core break after the book is glued with hot melt glue?

A4.a. The temperature of the hot melt glue is too low. b. The amount of glue applied is too low. c. The glue is uneven. d. The paper and the hot melt glue do not match.

Q5. Why are there bubbles in the glue layer after the book is glued with hot melt glue?

A5.a. The hot melt glue itself has bubbles. b. The hot melt glue contains moisture and produces bubbles when heated. c. The temperature of the melt glue is too high.

Q6. How to choose between EVA hot melt adhesive, PO hot melt adhesive, and PUR hot melt adhesive for book binding?

A6. If there is no special bonding requirement and cost is considered, choose EVA hot melt adhesive. If you are sensitive to odor and require good low temperature resistance, choose PO hot melt adhesive. If you require high and low temperature resistance and excellent bonding strength and toughness, choose PUR hot melt adhesive.
