What should I pay attention to for hot melt adhesive film in humid weather?

When the hot melt adhesive film faces humid weather, what problems should we pay attention to to make it play its due role? Let's take a look at the explanation of TPU hot melt adhesive film manufacturer Tepuyou Environmental New Material Co., Ltd.

The first point

1. If hot melt adhesive film is produced in this case, please pay attention to temperature changes and humidity changes in the equipment.

2. Changes in temperature and humidity will cause changes in the quality of the hot melt adhesive film, because in the production process, the use of ink and other glue and other raw materials will cause color changes due to humidity, which cannot meet the accurate color requirements. Therefore, in production, the requirements of the factory must be strictly controlled.

Second point

1. Next, the hot melt adhesive film will use a heat transfer machine in hot stamping.

2. These devices will get wet in humid air, which will affect the efficiency and effectiveness of operation.

3. Then, when using the equipment, the machine should be preheated first to remove moisture to make the hot stamping effect better.

Third point

1. Do you know how to save the remaining hot melt adhesive film? The editor made recommendations for storage conditions. The temperature is preferably within 25 degrees to prevent sunlight and prevent pressure.

2. If you need to store for a long time, pay attention to keeping the environment ventilated to keep the space smooth, which is more conducive to storage.

These are some of the issues that hot melt adhesive films need to pay attention to when facing humid climates. Hope they can help you.

TPU hot melt adhesive film vs anaerobic adhesive: "Scene flexibility" difference in automotive interior bonding
2025-09-11
​From the perspective of curing conditions, TPU hot melt adhesive film does not need to rely on special environments, while anaerobic adhesives are severely restricted by "auerobicity". The curing principle of anaerobic glue is to undergo polymerization under conditions of lack of oxygen and catalyzed by metal ions (such as iron and copper). If it is in an environment where air circulation or metal substrates are not available, the curing speed will be greatly slowed down or even unable to cure. In automotive interiors, most bonding scenarios are "open" (such as bonding the door panel skin to PP substrate, and the ceiling fabric to the sponge), the air can freely contact the bonding surface, and the substrate is mostly non-metallic (PP, ABS, fabric, etc.), lacking metal ion catalysis, and additional catalyst is required when using anaerobic glue, and the curing time is as long as several hours, which is difficult to meet the needs of industrial production. The TPU hot melt adhesive film only needs to be melted by heating (120-160℃) and can be cured after pressurization and cooling. It does not need to rely on the ambient oxygen concentration or the base material. It can be cured stably in open or closed bonding scenarios, and the curing time only takes a few dozen seconds to a few minutes, adapting to the fast-paced needs of the interior production line.
