How To Avoid Bubbles In Cold Lamination?
Cold lamination has a better lamination effect under low-temperature conditions, so we will properly heat the laminating film (below 60°C) to ensure the laminating effect. However, if the heating is excessive or the temperature is not uniform, bubbles will be generated.
The appearance of bubbles during cold lamination is very troublesome. How to avoid the appearance of bubbles?
To avoid bubbles during cold lamination, we must first understand the cause of the bubbles.
MEFU summarizes several reasons:
1. Problems with laminating film and laminating materials: If the laminating material itself is damp, has dust, or uneven surface, bubbles will appear in the finished product after lamination. If the laminating film has the same problem, it will also cause bubbles.
2. Problems with laminating machine parameter settings: Cold lamination has a better lamination effect under low-temperature conditions, so we will properly heat the laminating film (below 60°C) to ensure the laminating effect. However, if the heating is excessive or the temperature is not uniform, bubbles will be generated.
3. Laminating operation skills: Laminating work requires certain skills and experience. If the operation is improper, it may also cause bubble problems.
After understanding the causes of bubbles, we can avoid them:
1. Regularly check the film and laminating materials: The laminating materials should be completely dry, clean, and free of impurities before lamination; choosing high-quality laminating films is also the key to avoiding bubbles.
2. Reasonable setting of laminating machine temperature: Selecting different laminating temperatures according to the characteristics of different laminating materials can effectively avoid the generation of bubbles.
3. Laminating technology training: Before starting the laminating work, the operator should fully understand the characteristics of the laminating machine and master the skills of using the laminating machine.
