Put a certain amount of goods into the container bag. When testing, it should increase to nearly double the negative weight, and do different test experiments, repeatedly improve, and do more than one container bag.

Pull the full loaded container bag 0.8m away from the ground, let the bag fall naturally, observe whether there is any goods falling, and check whether the surface of the bag is damaged or not.
