Step 1: Receive customers' demand for paper bags

To be able to provide quality paper bags, paper bag printing manufacturers first need to receive and understand customers' needs.

• Paper bag size
• Text, image, the color shown on the bag
• Materials
• Production number
• Unit cost
• Specifications and styles

The consensus between the two parties about which information to print will help facilitate the next steps. The paper bag designs are varied depending on different purposes. We have compiled into 10 most common paper bag models, to which you can refer here.

Step 2: Design the paper bag

Based on the agreed basic information, the packaging manufacturer will create the structure and artwork designs.

The paper bag structure design shows the size, design, loading capacity, as well as other functional features of the bag. The artwork design is the skin layer showing all the information and messages customers want to convey.

After the customer evaluates and approves the actual sample, the packaging manufacturer will proceed to mass production.
 

Step 3: Print the paper bag

There are many printing technologies, such as offset, flexo printing, gravure printing, silkscreen printing, and digital printing ... Offset printing has many outstanding advantages, such as:

• Its image quality is higher, sharper, and cleaner than printing directly from a printing plate to paper because the rubber sheet is evenly applied to the printed surface.
• Cost savings. Print the more quantity, the lower the cost
• Printing time is very short, suitable for industrial printing where a large quantity of production is required.
• It is easy to produce an offset printing plate.

Therefore, offset printing is an excellent option for high-volume paper bag printing because of its high quality and low cost. Learn 5 basic steps in the offset printing process that you may not know in this article.
