How to determine the quality of aluminum-plastic composite cover?

Medical aluminum-plastic composite cover is mainly used in medical, chemical packaging and other industries. Different industries have different requirements for medical aluminum-plastic composite covers. In order to better understand the medical aluminum-plastic composite cover, let us look at how to judge the quality of the medical aluminum-plastic composite cover by appearance.

Check the riveting point: the riveting point has the same size, the surface should be smooth, the thickness is uniform, no burr, and the color is consistent with the color change of the plastic cover. The diameter of the riveting point should be 1-1.5mm larger than the diameter of the riveting hole of the aluminum cover. The automatic forming function of the medicinal aluminum-plastic combination cover can all meet the above requirements. When hand riveting, the surface will have unevenness, non-round edges, wire drawing, burrs, etc. Especially when riveting with hand tools, the electric heating temperature control, the riveting material is unevenly heated, there will be discoloration, or even burnt phenomenon. https://www.vial-box.com/flip-of...ssed-flip-off-seals.html
