Why does laminating film bubble? Below we analyze several common causes and provide solutions.
1. Improper Temperature
When the laminating machine temperature is too low, the adhesive layer of the laminating film cannot completely melt, resulting in a weak bond between the film and the document, which can easily form bubbles.
Solution:
Adjust the temperature according to the thickness of the laminating film; thicker films require higher temperatures.
Preheat the laminating machine to ensure that the machine reaches a stable operating temperature.
2. The laminating film or document is damp
If there is moisture on the surface of the document paper or laminating film, the moisture will evaporate when heated, causing bubbles.
Solution:
Keep the document and film dry before use.
In humid environments, lightly dry the document in a dryer beforehand.
3. Laminating film quality issues
Low-quality laminating film may have uneven adhesive application or defects in the material itself, which can easily cause bubbles when exposed to high temperatures.
Solution:
Choose high-quality laminating film, such as the laminating film produced by YIDU Factory. Its uniform adhesive layer and strong adhesion can effectively reduce bubbling.
4. Improper Operation
If the film and document are not aligned or placed unevenly when placed in the laminator, bubbles will form during the laminating process.
Solution:
Center the document and ensure that the film fits tightly against the document.
Feed the document into the laminating machine slowly during laminating to avoid tilting the document.
How to prevent bubbling in the laminating film?
Use a laminator with the appropriate temperature and speed.
Select high-quality laminating film.
Keep the document, film, and the environment dry.
Pay attention to detail and ensure that the film and document are placed evenly.
