Laminating pouches are originally used to protect documents, photos and various materials, but sometimes, after laminating, the film is found to be wrinkled, which looks very unsightly. What is going on? How to solve it? Today we will talk about the causes and solutions of laminating pouches wrinkling.
Why do laminating pouches wrinkle?
Temperature is too high or too low
If the temperature of the laminating machine is too high, the film will soften or even bubble, causing wrinkles.
If the temperature is too low, the laminating pouches cannot be fully fitted, and the clamped documents may have gaps, thus wrinkling.
Mismatched laminating speed
The machine is too fast, and the film is pulled over before it has time to fit, which is easy to wrinkle.
If the speed is too slow and the heating time is too long, it will also cause deformation.
Laminating pouches quality problem
If the film is too thin or the quality is unstable, it is easy to shrink unevenly after heating, which will also wrinkle.
The laminated items are too thick or uneven
If the laminated documents are too thick, or have creases, dust, etc., the film cannot fit tightly and wrinkles are likely to appear.
How to solve the problem of laminating pouches wrinkling?
1. Adjust the temperature of the laminating machine
The laminating temperature is set between 100-130°C.
If the film wrinkles, lower the temperature a little, test it several times, and find the most suitable temperature.
2. Control the laminating speed
The speed should not be too fast or too slow, and feed it into the laminating machine evenly and steadily.
Try to adjust the speed setting of the machine to find a suitable balance point.
3. Choose high-quality laminating pouches
High-quality laminating pouches are heated evenly and are not easy to wrinkle.
The laminating pouches produced by Vietnam Gangyue Film New Material Co., Ltd. are made of high-quality materials, with uniform thickness and strong heat resistance, which effectively reduces the wrinkling problem.
4. Make sure the laminated items are flat
Before laminating, make sure the documents have no creases, dust or foreign matter.
If it is thicker paper, try to flatten it before laminating.
5. Preheat the laminator
First, fully preheat the laminator and start the operation after the temperature stabilizes to avoid high and low temperature affecting the laminating effect.
