What Are The Classifications Of Plastic Bottle Caps?

I believe everyone is very familiar with plastic bottle caps. You will see it on every plastic bottle, but everyone only knows its use. Do you know what kinds of classifications it has? There are mainly screw caps, snap caps, welding caps, and other plastic caps. And the production processes and functions of different caps are also different. Depending on the color of the cap can be divided into: white cap, yellow cap, green cap, red cap, blue cap, etc. Basically, any color you can think of can be produced.

Basic classification of plastic bottle caps:

1. Screw cap

As the name implies, screw cap means that the cap is connected and matched with the container through its own threaded structure. Thanks to the advantages of the threaded structure, when the screw cap is screwed, a relatively large axial force can be generated through the engagement between the threads, and the self-locking function can be easily realized.

2. Push pull cap

The push pull cap is designed based on the high toughness of the plastic itself, maximizing its structural advantages. It is extraordinarily favored in industrialized mass production.

3. Flip top cap

Flip top cap has a simple structure and is characterized by a certain slot at the top of the cap. Advantages include good sealing performance, easy operation (one hand can open or close the cap), large cork opening, reusable, and wide application.

The production process of plastic bottle caps:

Plastic caps can be divided into: injection caps, pressure caps, injection caps mainly refers to the use of injection molding machine caps, there is a single injection molding and multiple injection and then combined caps, this can be used to liquor packaging, or cosmetics, perfume caps, etc.; pressure caps refers to the use of machine pressed caps, generally refers to aluminum caps or aluminum oxide caps, etc.
