1. Poor lamination film quality
If the lamination film itself is made of poor quality, such as recycled material, the adhesive layer is too thin, or the PET film is not strong enough, it can easily cause loose sealing, warping, or oxidation and yellowing.
Solution:
Choose lamination film with guaranteed quality and environmental certification.
2. Inappropriate thickness
If the film is too thin, it will easily wear out from frequent use. If it is too thick, if the machine temperature is not high enough, the seal will not be secure and may even delaminate over time.
Solution:
Choose the appropriate thickness based on the intended use for a stable effect.
3. Incorrect laminator temperature
If the temperature is too high, it will cause bubbling or deformation, while if the temperature is too low, it will not seal securely. Many people use the laminator without waiting for the machine to preheat, resulting in poor sealing quality.
Solution:
Always wait for the machine to preheat and ensure a stable temperature.
4. Improper Storage Environment
Although laminated documents are moisture-proof and waterproof, prolonged exposure to humidity, sunlight, or high temperatures can still damage the edges of the film, potentially causing mold and discoloration inside the document.
Solution:
Laminated documents should be stored in a dry, cool place, away from direct sunlight and moisture.
5. Improper Laminating Method
For example, improper laminating technique, failure to remove air bubbles, or pulling during the laminating process can affect the final result.
Solution:
Ensure that the document is placed flat, the film is aligned, and that the document is fed slowly and evenly into the laminator.
