Having control of web tension is necessary because it helps to reduce the wear and tear in the paper. The EPC system from Italy allows for automatic web alignment, which saves both paper and time.

It has a single feeding frame and an automatic glue system. After loading the paper roll on the shaft, it starts unwinding and the cutters cut the papers into the required shape.

Handle pasting unit makes handles of your required choice. In the next step, the paper and handles are mounted on the pasting unit. Here the handles are pasted with the paper bags through the system of glues. 

The bottoms of the papers are also glued to form the block shape. In the case of printing, the paper is printed prior to the handle pasting. 

After this process, the paper bags are shifted to the assembling unit. Here the square bottom paper bags are counted and accumulated.

Before going to that, let’s understand the sheet-feeding mechanism.

Sheet-fed mechanism

Sheet feeding machines can work manually and automatically depending upon their features. 

You can use paper sheets of different sizes in sheet-fed machines. 

In the automatic sheet-fed square bottom paper bag machine, the shaft automatically takes the paper sheets. However, in a manual system, you need to place the sheets by yourself.

After pasting the sides of the paper bags together, the bottom structure is complete.

These devices are typically used to produce small-format paper items such as brochures, Business cards which are used to promote a company, and Flyers

Can a square bottom paper bag machine make plastic windows in paper bags?

square bottom paper bag machine make plastic windows

Nova ensures that its personnel and equipment are up to date. As paper bags with plastic panes are becoming increasingly popular, Nova also provides solutions for making plastic windows. 

Nova has invented square bottom paper bag production machines that create plastic windows in the paper bags for this purpose.

These windows are in the form of strip and die-cut plastic windows. 

  • Strip plastic windows 

For making strip windows, you don’t have to cut the paper.  Plastic film is glued all the way around the front panel of the brown paper bag.

Strip plastic window paper bags are widely seen in bakeries. 

Hot temperature-controlled machines are used to connect the plastic film. A specified temperature is applied to the plastic window so that it adheres to the paper.

  • Die-cut plastic windows 

To make a die-cut plastic window, Nova inserts special die-cutters into the square bottom paper bag machine. These cutters are available in a range of sizes and shapes.

The cutter cuts the desired shape from the paper before forming the tube. The plastic film is glued to the paper web using an automatic adhesive process.

The plastic film works as an inside liner and provides a see-through window in the square bottom paper bag.

The sides of block bottom paper bags are sealed with a cold glue method.

With the help of a level sensor, the cold glue is automatically administered to the paper from an enclosed high-pressure storage tank.

However, we use hot glue to attach the handles to the paper bags.

  • Flat handles 
  • Twisted handles 
  • D-cut handles 

Flat handles have flat ropes. They are not twisted or folded by any means. These are mostly used in the retail and food industries.

Twisted handles have handle-loops that are twisted and used in fashionable paper bags. They add style to the square bottom paper bags.

D-cut handles are widely used in grocery stores for fruits and vegetables. These handles are not in the form of ropes, rather a D-shaped cavity is created on the paper tubes.
