The appearance quality of the Cosmetic Acrylic Bottle is divided down into material color, smoothness, transparency, etc.;
The first element is the color of the glass bottle
According to regional standards, there are three grades: fine white material, high white material, and ordinary white material; the same material color is the smoothness and transparency of the glass bottle. The appearance of the good bottle should be free of impurities, bubbles, cold spots, sticky bottles, There is no wrinkled skin, no putty, etc., and one more thing to pay attention to is the "double stitching" of the bottle body. Some glass bottle manufacturers are not strict in quality requirements, and there are often large stitches and double stitches; finally, watch directly Bottle body, large mouth glass bottle has better clarity and permeability, and small mouth glass bottle should not have particularly obvious dizzy wave patterns.
Secondly, the intrinsic quality of glass bottles
In this way, there are more subdivisions, such as the strength of the glass bottle, the temperature difference between the rapid cold and the hot temperature, the verticality of the bottle body, the thickness of the bottle body, no deformation of the bottle body, crooked neck, flatness, and roundness of the bottle mouth, no cold pattern frying, full silk pattern Pisi has broken filaments, and there is no diameter tumor in the bottle mouth. The most common problems are the following: small-mouth bottle crooked neck, small-mouth flat bottle body shaking, large-mouth bottle swelling, etc.; the result of small-mouth bottle crooked neck is that it affects the appearance and cannot be machine-filled and cannot be machine-sealed; the reason is Mould factors, fast production speed, unmatched bottle clamps, etc.; small-mouth flat bottle shaking is mostly caused by the failure of the anti-slip line at the bottom of the mold, but also the head printing deviation, and the fast speed of the machine. The consequence of the silk pattern is that the silk pattern becomes thicker and cannot be sealed. The reason is that the die is large and the heat dissipation is not good or the pumping head is shallow.
