The bottle mouth should be straight and smooth, no burrs (burrs) should be used, and the thread and bayonet fitting structure should be intact and straight. The fit between the bottle and the cap should be tight, with no slippery teeth, loosening, and no leakage. The inside and outside of the bottle should be clean.

Second, the basic quality requirements of flexible packaging.
