During daily use of laminating film, you may encounter issues with "loose adhesion" or "loose sealing." Documents may fall apart easily when pulled, or the edges may curl, which not only affects the appearance but can also cause moisture or damage. The causes of these issues are relatively simple. Let's analyze them one by one and provide solutions.
1. Insufficient Temperature
If the laminator's temperature is too low, the adhesive layer in the laminating film won't fully melt, resulting in poor adhesion.
Solution:
Raise the laminator's temperature appropriately or slow down the laminating speed to allow the laminating film sufficient time to heat and fully melt.
2. Laminating Film Quality Issues
Poor-quality laminating film may have an uneven adhesive layer or insufficient adhesion, resulting in poor sealing even at higher temperatures.
Solution:
Choose high-quality laminating film and ensure a thick, even, and strong adhesive layer.
3. Documents Too Thick or Uneven
If the laminating material is too thick or has an uneven surface, it can also result in a poor seal.
Solution:
Before laminating, ensure the document surface is clean and flat to avoid air or impurities.
4. Storage Environment Impact
Prolonged storage of laminating film in a humid or high-temperature environment may cause the adhesive layer to age, resulting in a decrease in adhesion.
Solution:
Store laminating film in a dry, cool environment, away from direct sunlight, and use it within its shelf life.
5. Laminator Issues
Uneven heating in the laminator or aging of the rollers may also cause the laminating film to seal poorly.
Solution:
Regularly inspect the laminator to ensure proper heating and pressure, and perform maintenance or replacement if necessary.
