First, non-essential processing technology
This face-to-face process is mainly to increase the aesthetic section of the product. Common processing techniques include:
1, film
It is a processing technique that coats the plastic film with an adhesive and heats and presses the printed product to bond them together. After the film has been coated, the film is smoother due to an extra layer of plastic film on the surface, and the gloss and color are also better. The graphics are bright and three-dimensional, and they are waterproof, stain-proof and wear-resistant. Fold-resistant, corrosion-resistant features.
2, glazing
A common technique in high-grade prints is to coat (or spray or print) a colorless, transparent coating on the surface of the print, thereby forming a thin, uniform, transparent and glossy layer on the surface of the print. It not only protects prints, but also changes the texture and visual effects of prints.
3, from the drum
The process name is embossing and embossing, that is, a piece of intaglio plate and a relief plate with a close fit, and the printed matter are sandwiched. Under a certain pressure, a graphic or a pattern similar to the relief plate is formed on the surface of the printed product, so that the printed product has a distinct sense of relief.
Second, the necessary processing technology
Because the jacket has a distinctive feature in its structure, it has a paper pocket for loading documents (called "tongue" inside the printing industry), and the production of this part must go through "folding" and "paste". The process.
1, folding
By mechanical action, set indentations that change the shape of the material on paper or other cut sheets to facilitate folding.
2, paste
The print is adhesively formed. According to the choice of adhesive, adhesive strength, and the use of environmental restrictions will be divided into general and high quality paste, in two cases.
It should be noted that, in general, these two processes need to be priced separately and cannot be ignored when calculating the cost of printed materials.
In addition to the advantages of convenient opening and multiple sealing of bottle and barrel packaging, upright bag with mouth has the advantages of less consumption of packaging materials, high printing decoration, low packaging storage, low transportation cost and small waste disposal, and is praised as an environment-friendly packaging. According to statistics, compared with bottles and barrels of the same capacity, the raw material consumption of upright bags with mouth can be reduced by more than 30%, the storage and transportation cost of packaging materials can be reduced by more than 60%, and the waste disposal volume can be reduced by more than five times. These bags have many excellent functions , just like Waterproof, moisture-proof, UV- proof, prevent leakage, Prevent food from odor,extend product preservation time etc, you can pack drinks, juice and washing liquid safely , for the bag`s shape , size , thickness, color which we can customize according to your requirements, we can provide the best quality and service for you .
