Square bottle capping machine

There are several types of capping methods used in square bottle capping machines. Some of the common types include:

1. Screw capping: In this method, the cap is screwed onto the bottle using a rotating spindle. This is a popular method for square bottles as it provides a secure seal.
2. Snap capping: This method involves snapping the cap onto the bottle using a set of jaws. It is often used for bottles that have a narrow neck.
3. Press-on capping: This method involves pressing the cap onto the bottle using a set of rollers. It is often used for bottles that have a wide neck.
4. Corking: This method involves inserting a cork into the bottle neck and compressing it using a set of jaws.

The choice of capping method will depend on factors such as the type of product being bottled, the viscosity of the product, and the desired level of seal.
