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.

Misconception 1: Increasing the amount of glue applied can make it stick Many operators find that the BOPP film surface cannot stick, and their first reaction is to add glue. In fact, increasing the adhesive amount from 40g/m ² to 80g/m ² does not increase the bonding strength by less than 20%, but instead causes […]
Direct answer: The consumption of adhesive particles is relatively high, and 90% of the problem lies in four areas – excessive setting of adhesive amount, waste caused by improper temperature, equipment leakage, and mismatched selection of adhesive particles. After item by item investigation, most factories can reduce unit adhesive consumption by 15% -30% without sacrificing […]
How to deal with hot melt adhesive particles burning and smoking? First, give the order of disposal:Immediately lower the temperature of the glue pot by 20 ℃ → exhaust and ventilate → stop adding new glue → remove the coking glue from the pot → check if the temperature control is malfunctioning again.The essence of […]
The role and key elements of bookbinding adhesive in binding are the key to the quality of bookbinding! Hot melt adhesive becomes brittle when cooled, the back adhesive layer is not smooth, and insufficient penetration of the adhesive liquid leads to non stick properties. These are the issues that most books and publications face when […]
