Selection method of aluminum-plastic cover

In terms of the selection of aluminum-plastic caps, according to the structure and shape of aluminum-plastic caps, it has a great impact on the sealing quality of large infusions. The size is probably determined according to the diameter of the mouth of the salt water bottle, if it is too large, it will be difficult to seal firmly, and if it is too small, the cover will go down.

Although there are relevant rules for the diameter of the bottle mouth, some manufacturers do not strictly implement the standards, resulting in different details. In addition, the standards of each manufacturer acquired by the medical unit are there, and the comparison is messy. Therefore, in the case of regular aluminum-plastic cap standards, salt water bottles of different calibers should be selected and suitable bottle caps should be selected.

The shape of the aluminum-plastic lid is usually multi-digit and flat-topped, and the shape after restriction depends on the capping mold of the capping machine. If the mother and child and the flat top are sealed into an aluminum-plastic cap flat top, it will often not be tightly attached to the cork, and it is easy to loosen the appearance. However, if the mold is changed to rounded corners and the country is restricted, this defect can be overcome.
