Step 1: Receiving Customer Requests for Paper Bags

In order to ensure the production of high-quality paper bags, manufacturers specializing in paper bag printing begin by receiving and comprehending customers’ specific requirements.

  1. Determining Paper Bag Dimensions: (Length × Width × Height/Depth)
  2. Design Elements: Customers can provide instructions regarding the inclusion of text, images, and color preferences for the bag’s design.
  3. Choice of Materials: Art Paper, Silver Card, Gold Card, Black Card, Special Paper, Kraft Paper, or according to customer requirements
  4. Quantity: The number of paper bags required for production is confirmed.
  5. Specifications and Styles: Both parties work together to finalize the specific details and styles of the paper bags to be produced.


Step 2: Paper Bag Design

Using the provided basic information, the packaging manufacturer will develop the structure and artwork designs for the paper bag.

The structure design includes the bag’s size, design elements, loading capacity, and functional features. On the other hand, the artwork design represents the outer layer that displays all the desired information and messages to customers.

Once the customer reviews and approves the physical sample, the packaging manufacturer will proceed with mass production.


Step 3: Printing the Paper Bag

Various printing technologies are available, including offset, silkscreen printing, and digital printing. Offset printing offers several notable advantages, such as:

Superior image quality: The use of a rubber sheet evenly applied to the printed surface results in higher, sharper, and cleaner images compared to direct printing from a plate to paper.

  • Cost savings: The more quantity you print, the lower the cost per unit, making offset printing a cost-effective option.
  • Short printing time: Offset printing is suitable for industrial-scale production that requires large quantities, as it offers a quick printing process.
  • Ease of plate production: Offset printing plates are relatively easy to produce, adding to the efficiency of the printing process.

Given its combination of high quality and low cost, offset printing is an excellent choice for high-volume paper bag printing. To learn more about the difference between the offset printing and digital printing process, explore the details in this article.
