Hot melt glue machine is a common industrial equipment, widely used in carton packaging, cardboard manufacturing and other industries. It heats the solid glue block to convert it into molten glue, and then applies the glue to the cardboard by spraying or coating to achieve the bonding effect. The following will introduce the application of hot melt glue machine on cardboard.

1. Cardboard packaging: Hot melt glue machine plays the role of bonding cardboard in cardboard packaging. When making cartons, the cardboards need to be firmly connected to ensure that the structure of the carton is strong and can withstand heavy objects and vibrations during transportation. The hot melt glue machine can spray hot melt glue on the seams of the cardboard or other locations that need to be bonded. The glue liquid quickly cools to form a strong bonding layer, which firmly connects the cardboards together.

2. Cardboard repair: During cardboard packaging or carton transportation, the cardboard may be damaged or cracked due to external impact or other reasons. The hot melt glue machine can glue the damaged parts together by spraying hot melt glue, repair the damage of the cardboard, and maintain the integrity and service life of the cardboard.

The application of hot melt glue machine on cardboard has the following advantages:

1. High efficiency: The hot melt glue machine can quickly melt the solid glue block into a molten liquid, and the glue liquid quickly cools down after contacting the cardboard to form a strong adhesive layer. This high efficiency can improve production efficiency and reduce downtime in the process.

2. Uniform coating: The hot melt glue machine can achieve uniform spraying or coating of the glue liquid, ensuring that all parts of the cardboard can be fully bonded. This is very important for quality control in the cardboard manufacturing and packaging process.

3. Environmental protection: The hot melt adhesive used in hot melt adhesive machines is usually made of environmentally friendly materials, does not contain organic solvents and volatile organic compounds, and does not pollute the environment.

Hot melt adhesive machine provides a reliable bonding solution and is widely used in carton packaging, cardboard manufacturing and other industries, providing reliable packaging materials for product transportation and protection.
