How does Vertical Automatic Packaging Machine Work?

Vertical automatic packaging machine , also known as vertical form-fill-seal (VFFS) machines, are commonly used in the packaging industry to automatically form, fill, and seal bags or pouches. These machines are capable of packaging a wide variety of products, including food items, pharmaceuticals, hardware, and more.

Here's a general overview of how a vertical automatic packaging machine works :

Film Unwinding: The packaging process begins with a roll of packaging film mounted on a film spindle. The film is unwound from the roll and fed into the machine.

Film Forming: The film passes through a set of forming devices, such as forming tubes or collars, which shape the film into a tube or a cylindrical shape.

Vertical Sealing: The edges of the film tube are sealed vertically, creating a continuous back seal. This seal ensures that the product remains inside the packaging.

Product Filling: The product to be packaged is introduced into the film tube through a product filler, such as a volumetric filler or weigher. The filler accurately measures or weighs the product and releases it into the packaging.

Horizontal Sealing: As the product is being filled, the packaging machine advances the film tube vertically. When the desired amount of product has been dispensed, horizontal sealing jaws close and create a seal below the product, forming individual pouches or bags.

Bag Cutting: Once the horizontal seal is formed, a cutting mechanism severs the film above the seal, separating the pouch or bag from the continuous film tube.

Structure of vertical automatic packaging machine

A vertical automatic packaging machine consists of a film unwinding system, forming devices to shape the film into a tube, vertical sealing mechanisms to create a continuous back seal, product filling components, horizontal sealing jaws to form individual bags, a cutting mechanism to separate the bags, and a bag discharge system. Optional features like printing batch codes or attaching zippers may also be included.

 

Vertical automatic packaging machines are widely used in the packaging industry for various applications. They are employed to efficiently package a diverse range of products, including food items, pharmaceuticals, hardware, and more. These machines streamline the packaging process by automating the tasks of forming, filling, and sealing bags or pouches. With their versatility and speed, vertical automatic packaging machines contribute to increased productivity, improved product hygiene, and enhanced packaging aesthetics.
