Packaging of the photo frame:

Mainly the carton is foam-proof.
Use Poly Dragon, which is foam. According to the pressure of the picture frame, it is easy to deform, and the glass is easy to break under pressure. Therefore, pay attention to the compactness of the packaging and do not dangle it. Also pay attention to anti-vibration, the filling material used should not be too hard, must have a certain elasticity, it is best to pack each picture frame with bubble bags, both shock-proof and not easy to scratch.
You can use Poly Dragon to separate the picture frames one by one. Pay special attention to the glass should be close to Poly Dragon, so this Poly Dragon film is best to have a circle of grooves to place the picture frame. Or you can use a thinner Polyuron or cardboard (carton paper) in the middle, not too thick.

There are various types of hanging frames. There are swing-table and wall-mounted ones.
