What is the biggest fear when buying Laminating Film? Of course, buying a product of poor quality! Today, I will teach you a few super simple judgment methods. You can test the quality of Laminating Film at home without professional equipment.
1. Look at the appearance first
The surface is smooth and flat, without bumps and bumps
High transparency, as clear as glass
No impurities, black spots or bubbles
The edges are cut neatly, not rough
2. Feel the feel
High-quality Laminating Film:
✓ It feels delicate and smooth
✓ It has a certain elasticity and is not too brittle
✓ The thickness is uniform, without the feeling of uneven thickness
Low-quality Laminating Film:
✗ The surface is rough and grainy
✗ Too hard or too soft
✗ It feels greasy
3. Simple test
Fold the Laminating Film in half several times:
Good film: shallow creases, can be restored to flatness quickly
Poor film: deep creases, and may even turn white and crack
4. Smell the odor
Qualified products: no odor, or a very light plastic odor
Low-quality products: pungent chemical odor
5. Actual plastic sealing test
The last step is the most practical:
Use ordinary A4 paper to seal
Observation:
Is it easy to wrinkle?
Is the edge bonding firm?
Will the edge curl after laminating?
Remember these 5 points:
Check whether the appearance is clean and smooth
Touch whether it feels fine
Fold it to see if it is elastic
Smell whether it has a pungent smell
