How do you manufacture a paper bag? 2025 New

If you want to make paper bags by hand, you must first determine the thickness of the paper. If the paper thickness is >100gsm and it is not easy to bend by hand, you will need a die-cutting machine for die-cutting. You need to go through the following steps to make a paper bag:

(1) Paper creasing

(2) manual paper side gluing

(3) paper side pasting

(4) Folding the paper gusset

(5) Opening the paper bag bottom

(6) Folding the bottom in half

(7)paper bag bottom gluing

(8) paper bag sealing.

This is how a basic paper bag is made.

As time goes by, the requirements for the quality of paper bags are getting higher and higher, and the requirements for craftsmanship are also getting higher and higher. The reasons are (1) the need to load items of different weights (2) to better demonstrate the brand image of the company.

To improve the load-bearing capacity of paper bags, folding the paper bag mouth, reinforce top card, insert bottom card, punching hole,manual stringing, etc. have been gradually added, or paper handles have been directly pasted.

There are many steps involved in making a paper bag. Each person can only produce 300 bags in 12 hours. In addition, due to the inevitable manual errors in the paper gluing stage, there are large errors between large batches of handmade paper bags. The output and quality of paper bags will become important factors restricting the development of enterprises. Therefore, Zenbo has been trying to automate and standardize the production of paper bags since its establishment in 2009.

At this stage of development, there are professional machines to produce corresponding paper bags for different types of paper bags.

A professional fully automatic machine can make paper into full paper bags in one time forming, but the price of a fully automatic machine is relatively expensive. The paper bag company needs to have more paper bag orders to quickly recover the cost of the machine and continue to produce paper bags to earn money.

Since paper bags can be made step by step, buying a machine that includes part of the paper bag making process can also greatly reduce labor. For example: paper bag tube gluing machine, paper bag bottom gluing machine, etc.

Paper bag gluing machine: including automatic paper feeding, gluing, pasting, folding gusset, compacting and output. With the update of machine functions, the top folding function has been added.

Paper bag bottom gluing machine: including manual bag feeding, hot melt glue (water-based glue), bottom sealing, compaction and forming. With the update of machine functions, automatic paper bag feeding and automatic insert bottom card have been added.

By combining manual work with machines, production efficiency is greatly enhanced and the precision of each paper bag is improved.

If you are currently using large quantities of manual paper bags, and want to gradually improve the accuracy and stability of paper bags through machines, whether you start the transition from semi-automatic or use a fully automatic machine to directly complete the process from paper to paper bags, Zenbo can provide a complete solution to help you earn more money.
