I want to make 3M light box cloth doors, so I searched several 3M companies on the Internet, thinking about comparing prices, but I don’t know that the prices are very different? What happened here?

What are the differences between them, leading to a large price gap. ...

One, the material is different

Inferior 3M cloth, soft texture, thin thickness, low tear strength, and feel no difference from ordinary light box cloth. The authentic 3M light box cloth feels stronger and thicker in your hand.

Two, the use period is very different

Compared with the price of genuine 3M light box cloth, inferior cloth is much cheaper, but the service life is also very different. The genuine product has a three-year warranty, but it can be used for 4 to 5 years, and there is no quality guarantee for inferior fabrics. If you are lucky, they can be used for 3 years. If the quality is poor, it will only be 2 years old.

3. In terms of lighting effects, the effect was not bad at first, but after a while, the inferior 3M cloth will be revealed.

As mentioned above, inferior fabrics are soft and have low tear resistance, so they are not resistant to outdoor cold and strong winds. There are frequent strong winds, the picture swings back and forth, and the ductility is poor, causing the picture to be uneven.
