Performance comparison of three kinds of medical aluminum-plastic composite cover

The fundamental reason for the appearance of the aluminum-plastic combination cap is not only because of its beautiful appearance and convenient opening, but more importantly, because the original rubber stopper for sealing the bottle mouth has been eliminated, and replaced by a new material bottle mouth. Seals-butyl rubber. Therefore, the aluminum-plastic composite cover is used in conjunction with the butyl rubber stopper. The aluminum-plastic combination cover is the product after replacing the butyl rubber stopper. At present, my country's aluminum-plastic composite cover has the following three commonly used cover types:









Breakpoint




Flanging




Notched






Features




.
The opening force of the plastic cover is determined by the width of the connection point, the general connection point is
~
pieces with a width of.
~
.mm


.
The plastic cover is assembled together by hot pressing and riveting.


.
Tear the connection point of the aluminum cover through the riveting point of the plastic cover to complete the opening function.




.
The opening force depends on the width of the plastic cover flange, the thickness of the flange material and the shape of the flange.


.
The plastic cover is folded and deformed by hot pressing and combined with the aluminum cover.


.
Through the elastic deformation of the plastic cover flange, the opening function is completed.




.
Rely on the depth of the notch to ensure the opening force.


.
The plastic cover is assembled together by hot pressing and riveting.


.
Tear the nicks of the aluminum cover through the riveting points of the plastic cover to complete the opening function.






Advantages




.
Easy to manufacture


.
Stable opening force




.
Easy to manufacture


.
Plastic and aluminum lids are easy to recycle




.
Good sealing performance


.
Easy to clean






Disadvantages




.
The aluminum ring is not easy to recycle after the plastic cover is opened.


.
When the cotton ball sterilizes the rubber stopper, it is easy to hang the cotton ball at the tearing point.






.Opening force is not easy to control




.The aluminum ring is not easy to recycle after the plastic cover is opened.


. The notch processing is difficult, if the processing accuracy is not enough, the opening force will be unstable







From the above three types of aluminum-plastic composite lids, we can see that the functions of the aluminum and plastic lids in the so-called aluminum-plastic composite lid are: The sealing of the bottle mouth; the plastic cap is shaped by the change of shape and color to shape the appearance of the combined cap, and the image of the company is shaped through the pattern on the plastic cap and the corporate trademark, and the mission of the combined cap is completed by the plastic cap-opening.


As a pharmaceutical company, we all hope to use those aluminum-plastic composite covers with reliable quality, beautiful appearance, and their own corporate trademarks to encapsulate our various preparations. When these preparations are used in hospitals, they all hope to use stable opening force. , Easy-to-open aluminum-plastic lid combination.
