Common processing technology of Paper Bag

With the advancement of national technology, the Paper Bag printing factory has also made great progress in the Takeaway Paper Bag printing process. Today, the common processes are UV, bronzing, glazing, embossing, lamination, etc. Using these processes can make ordinary Paper Bags a high-end atmosphere. Today, WELMBAGS will tell you about these common processes.

Here is the content list:

• UV process

• Varnishing process

• Embossing process

• Lamination process

UV process

UV is mainly used for brightening and adding dimension. Most of them are used on the company's Paper Bag LOGO. UV printing has good printability for most substrates. UV printing is clear and smooth with high printing consistency. At the same time, since the UV curing process is a photochemical reaction process, both the ink layer and the light oil layer have strong adhesion, durability, chemical resistance, abrasion resistance, aging resistance, and other advantages.

Varnishing process

The process of varnishing oil is to prevent the ink between the Paper Bag and the Paper Bag because a large area of printing content accumulates a lot of ink, and the ink will not dry in a short time, and it is easy to scratch the ink to other Papers Bag. This is common discoloration, but discoloration can be effectively prevented by varnish.

Embossing process

Embossing is the process of creating plastic deformation by applying a printed product under a certain pressure using a concave and convex mold to treat the surface of the printed product. After printing, the surface of the print has different patterns and textures. It has a distinct three-dimensional feel that enhances the artistic appeal of the print. Embossing is a commonly used process in the printing process of a Square Bottom Paper Bag. It uses a concave-convex mold and a pressure printing process determined by a press so that the surface of the printed Paper Bag is produced according to the corresponding pattern of the mold. It is a printing process for surface processing. So what are the benefits of adding embossing to printing? Embossing can make the flat pattern three-dimensional and increase the infectiousness of the Paper Bag. It can also be used to emboss the paper as a whole so that the whole Paper Bag can produce a completely different texture and three-dimensional effect from other papers. We have a Paper Bag, customers need to customize and find a special paper pattern for their new product, mainly because the texture of the special paper is very close to their product, but the output and cost of the special paper they need exceed them. At that time, it was suggested that they use coated paper with full embossing. Embossed patterns can be provided by them, solving their doubts in terms of cost and usage. The embossing process is not only used in the process of making Paper Bags, but other handicrafts also use the embossing process in large quantities. However, in the printing of Paper Bags, the embossing process is generally used for clothing Paper Bags and Gift Paper Bags in the packaging.

Lamination process

The effect of the bright film is that the surface of the Paper Bag looks very beautiful. The bright film and bright film will reflect the ambient light, which is a specular reflection. In addition, the bright film is relatively bright, and there is no frosted feeling, and the color of the bright film is brighter. The matte film makes the printed matter darker and looks softer, and the bright film makes the printed matter more brilliant, but it is prone to random reflections, and the cost of the matte film is higher than that of the bright film.
