Regarding the sealing method of aluminum caps, let me briefly introduce the issues of recycling and selecting aluminum caps. In terms of the selection of aluminum caps, the size, structure, and shape of the caps have a significant impact on the sealing quality of large infusion fluids. The size should be determined based on the diameter of the saltwater bottle mouth. If it is too large, it will be difficult to seal it firmly. If it is too small, it will be covered with cloth. Although there are relevant regulations for the diameter of bottle caps, some manufacturers do not strictly adhere to the standards, resulting in differences in size. In addition, the specifications of various manufacturers purchased in medical institutions are quite messy.
Therefore, when specifying the specifications of aluminum caps, saltwater bottles with different diameters should be selected and suitable bottle caps should be selected. The shape of aluminum caps is generally multi position flat, and the shape after pressing depends on the capping mold of the capping machine. If the mother and child are sealed into an aluminum cap with a flat top, it often cannot tightly adhere to the bottle stopper, which can easily cause loosening. However, if the mold is changed to rounded corners and pressed by Qing Guo, this drawback can be overcome.
