Analysis of embossing process for packaging paper bags

Common types of embossing

In the design and production process of packaging bags, embossing technology is a commonly used processing method, which can make some patterns or textures appear on the surface of the packaging bag, increasing its beauty and touch. Common types of embossing include the following:

1. Ordinary embossing: Commonly used simple patterns such as lines, squares, dots, etc. can be pressed through process templates and embossing rollers, with simple effects but deeply loved by consumers.

2. Raised embossing: Compared with ordinary embossing, raised embossing has a more three-dimensional and realistic effect, which can be produced through processing molds and heating rollers. Applied to high-end packaging boxes, cards, and other products.

3. Concave embossing: Unlike convex embossing, concave embossing needs to be made through pressing molds and cooling rollers, with a softer and more natural effect, suitable for packaging bags, paper products and other products.

Production process

1. Design pattern: Firstly, it is necessary to convert the designed pattern into a template that can be pressed, and calculate and determine each detail.

2. Manufacturing molds: Based on the designed template, manufacture corresponding pressing molds and rollers.

3. Prepare paper: Select suitable paper for pre cutting, folding, and hot stamping.

4. Pressing process: The produced paper is combined with heating rollers and pressing molds to form patterns or textures through pressing, heating, cooling, and other steps.

5. Follow up processing: Finally, clean and organize the produced packaging bags to make them more perfect.

Precautions

1. When pressing, it is necessary to heat the mold and roller, and the temperature needs to be controlled within a certain range to avoid problems such as paper gelatinization and oxidation caused by excessive heat.

2. The choice of paper is also very important. Choosing materials with moderate strength and easy processing can greatly reduce production costs, while also paying attention to factors such as the glossiness and flexibility of the paper surface.

3. Each production process needs to be strictly controlled to ensure the stability and consistency of the process, so as to ensure the quality and effectiveness of the product.

In short, the embossing process of packaging bags plays an important role in packaging design, and its details also need to be carefully controlled and mastered. I hope this article can help everyone better understand the embossing process of packaging bags and play an innovative role in future production practices.
