Box Type Paper Bag Making Machine – The Definitive FAQ Guide

Box type paper bags have prevailed in different industries over the years.

Many retail and food industries long for the box type paper bags due to their vicious space and strength.

If you are going to start a business of box type paper bags, then you are at the right place.

I’ll tell you in depth the working of the box type paper bag machines and their benefits.

1. What Is Meant by Box Type Paper Bag Making Machine?

A box type paper bag is a low-cost approach to package a variety of products.

It usually has a rectangular bottom, unlike a flat or satchel paper bag. Because thicker paper material can hold greater weight, this type of paper bag is more extensively employed in various fields.

Box type paper bags with printed company information can also be used for brand marketing and product advertising.

Box type paper bag making machine is an electromechanical machine that converts roll paper material into box bottom paper bags (also named as ” block bottom paper bag” or “square bottom paper bag” or “SOS paper bag”.)

The bottom folding structure of the square bottom paper bag making machine is more sophisticated than that of the flat and satchel paper bag making machine.

It also includes more customization options for certain functions.

Box type paper bags have a wide range of applications and can be used to pack fast food, gourmet, gift, hardware, medicine, and more.

2. How Does a Box Type Paper Bag Making Machine Work?

Your box type paper bag making machine has the following mode of working.

HMI Control Panel

In order to start, the operator enters all the required data into the control panel that includes the paper bag’s dimensions and the working speed.

Paper Roll Unwinding

The method starts at the end of putting the material in the machine. In the unwinding unit, a hydraulic shaft carries the paper roll.

The paper roll unwinds mechanically, resulting in a stretched, aligned web of paper.

Paper Web Formation

The paper roll is un-winded which results in a stretched and straight paper web. The EPC system is in charge of the web tension control sensors.

These sensors aid in the detection of the correct paper tension based on a scale.

Using tractioning rollers and friction wheels, the paper web tension is maintained at various speeds.

Side Gluing

Water-based glue is applied to the paper web’s side with gluing guns.

The glue guns spray a precise amount of glue onto the paper, securely adhering it to the tube and forming it.

Paper Tube Formation

Following that, the paper web is put into the tube-forming part.

In this unit, the paper web is folded using a forming plate or a forming template.

The forming template determines the width of the paper bag. Folding the sides inward with the side edge discs creates side gussets.

Friction wheels and pull rollers stretch and align the paper tube while firmly pressing the folds.

The side seams are additionally sealed with the help of pressure.

Tube Cutting

After exiting the tube forming unit, the paper tube enters the cutting unit. It is equipped with a sharp knife that slices the brown paper tube to the desired bag length.

Bottom Formation

The cylinder-shaped paper bags are sent to the bottom-forming apparatus. The mechanical fingers help open the bottom of the paper bag.

Glue is used to cover the bottom. The bottom folding device folds the paper and seals the bottom suitably.

Bag Counting

At this moment, the paper carry bags are ready. The bags are then mechanically counted in a bag counting unit by the equipment.

Accumulating Table

The machine then discharges the counted paper carry bags in predetermined groups. The operator, for example, instructs or programs the control panel to discharge 25 bags at once.

The machine will release 25 bags, then pause for a few seconds before releasing the next set of 25 bags.

By the above-mentioned steps, your machine makes box type paper bags.
