If, like many manufacturers, hot melt adhesive on the packaging line may encounter problems, resulting in slower packaging speed, increased costs, and potential product damage or loss. Let’s take a look at the common hot melt adhesive problems that manufacturers face today and explore possible solutions.

Problem 1: UsingHot melt adhesiveToo little
If your packaging accidentally opens during assembly, storage, or distribution, it may indicate that too little hot melt adhesive was used. Although attempts may be made to use less hot melt adhesive to help reduce overall packaging costs. But the time and effort spent returning and reapplying hot melt adhesive on the opened box – not to mention the cost of lost or damaged products due to packaging rupture – exceeded any potential savings. Ensure that sufficient packaging hot melt adhesive is used to form a strong bond.
Problem 2: Excessive use ofhot melt adhesive
Using too much hot melt adhesive can greatly consume hot melt adhesive and increase usage costs, and may also lead to additional packaging issues, such as longer fixation time or damage to the external pull wires of the packaging. When it comes to hot melt adhesive, more is not necessarily better. Collaborate with your adhesive supplier to determine how much packaging hot melt adhesive your application requires.
Problem 3: Not considering extreme temperatures
When choosing the appropriate hot melt adhesive for your packaging needs, be sure to keep in mind the temperature and humidity/humidity level so that you won’t encounter any problems. Please remember to consider not only the temperature at which the product is placed in packaging, but also the temperature to which the product is exposed during production, storage, and distribution.
Some types of hot melt adhesives perform better at extremely high temperature and humidity levels, while others are more suitable for low temperature and low humidity levels. Collaborate with your suppliers to explore the most suitable packaging hot melt adhesive for your specific needs.

Direct answer:Hot melt adhesive pelletsThe cost of raw materials generally accounts for 65% to 80% of the factory price. Taking EVA type hot melt adhesive granules commonly used in book binding as an example, in 2026, the raw material cost will be approximately 9000-13000 yuan per ton, while the finished product price will mostly fall […]
Direct answer: The smaller the particles, the faster they melt, but to a certain extent, it can lead to new problems such as clumping, clogging, and carbonization. For most book binding and sealing equipment, a standard particle size of 3-5mm is the most comprehensive and optimal, and blindly pursuing small particles is a typical misconception. […]
Handbags are indispensable daily necessities in our lives, so the market sales of hot melt adhesive for handbags also account for a large proportion of the entire hot melt adhesive market. Some people buy hot melt adhesive sticks to manually bond handbags, while others buy hot melt adhesive granules to machine bond handbags. Here are […]
Hot melt adhesive is a type of thermoplastic that melts into a solid state by heating and applying temperature. When the adhesive begins to solidify (heat loss) before the material is bonded, cold bonding occurs, which can lead to bonding failure. Usually, it appears to be firmly adhered after bonding, but the bonding strength may […]
