Color-printed woven bags are a common packaging material and are widely used in food, cosmetics, daily necessities and other industries.

It increases the aesthetics and publicity effect of the product by printing colorful patterns or text information.

In order to ensure the quality and use effect of color printed woven bags, coatings and surface treatments need to follow some standards.

The following are common standards for coatings and surface treatments for color printed woven bags.

1. Coating selection.

Color-printed woven bags generally use flexible coatings, which mainly include solvent-based coatings, water-based coatings and solvent-free coatings.

These coatings have high adhesion, durability and abrasion resistance, and can keep the color and texture of the bag stable under different environmental conditions.

2. When choosing coatings, you also need to consider the uses and special needs of color-printed woven bags.

For example, food packaging needs to choose coatings that meet hygienic standards, and cosmetic packaging may need to choose coatings that are resistant to chemical solvents.

In addition, for some color-printed woven bags that require special surface treatment, such as waterproofing, UV protection, etc., corresponding special coatings need to be selected.

3. Next is the construction of paint.

The coating construction of color-printed woven bags generally includes printing and drying.

During the printing process, the thickness and color uniformity of the ink need to be controlled to ensure that the printing effect meets the requirements.

During the drying process, the temperature and time need to be controlled so that the paint can fully solidify on the bag to improve the durability and color stability of the bag.

4. Paint construction also requires attention to environmental protection and safe operation.

During the operation of the printing press, it is necessary to control the discharge of waste water and the treatment of waste ink to avoid environmental pollution.

Staff need to wear protective equipment when operating.

Especially when using toxic and hazardous paints, be sure to wear a respirator to protect your own safety.

5. In addition, the surface treatment of color-printed woven bags is also one of the most important links.

Common surface treatment methods include bright surface treatment, rough surface treatment and anti-slip treatment.

The bright surface treatment can increase the gloss and touch of the bag, and the rough surface treatment can increase the anti-slip property and feel of the bag.

Anti-slip treatment can improve the safety of the bag during use.

The choice of surface treatment depends on the specific use and design requirements of the color printed woven bag.

6. When performing surface treatment, it is necessary to control the concentration of the treatment agent and the uniformity of the coating.

At the same time, you also need to pay attention to the selection of surface treatment agents.

Some surface treatments may contain hazardous substances and need to ensure compliance with environmental and health standards.

In addition, the surface-treated bags need to undergo quality inspection to ensure that the treatment effect meets the requirements.

7. To sum up, the coating and surface treatment of color-printed woven bags need to follow some standards to ensure the quality and use effect of the bag.

The choice of coating needs to consider the use and special needs. During the construction process, the thickness and uniformity of the ink need to be controlled, while paying attention to environmental protection and safe operation.

Surface treatment requires different methods to be selected according to specific requirements, and quality inspections are conducted to ensure that the treatment effect meets the requirements.

By strictly following the standards for coating and surface treatment, color-printed woven bags of excellent quality can be produced to meet customer needs.
