How to choose ink for printing paper bags
Date: Aug 01 2024 From: Star Color
The application of paper bags is very extensive. Compared with plastic bags, paper bags are more environmentally friendly. At the same time, paper bags also have good weight capacity. Paper bags are simpler to print than plastic bags. As for which ink to choose for printing paper bags, we can analyze the characteristics of various inks.
Water-based inkFeatures: Water based ink uses water as a solvent instead of traditional organic solvents, which has the advantages of environmental protection, non toxicity, and no irritating odor. Meanwhile, water-based ink has a moderate drying speed and good color performance, making it suitable for various paper and cardboard materials.
Applicable scenarios: For most paper bag printing, especially food packaging paper bags and paper bags that need to meet environmental standards, water-based ink is an ideal choice. It can meet basic printing requirements while reducing its impact on the environment and human health.
UV inkFeatures: UV ink cures quickly through UV irradiation, with advantages such as fast drying speed, bright colors, light resistance, wear resistance, and chemical resistance. Its printing effect is delicate and suitable for high-quality printed materials.
Applicable scenarios: If paper bags need to display exquisite patterns or colors and have high requirements for printing speed and quality, UV ink can be chosen. However, it should be noted that the curing of UV ink requires specialized UV irradiation equipment, which may increase equipment costs and operational complexity.

Solvent based inkCharacteristics: Solvent based ink is composed of resin, pigment, solvent, and additives, and has the characteristics of fast drying speed, strong adhesion, and good wear resistance. However, solvent based inks contain volatile organic compounds (VOCs), which have a certain impact on the environment and human health.
Applicable scenarios: Although solvent based inks are still used in certain specific situations, they should be avoided as much as possible in paper bag printing due to environmental considerations. If it is indeed necessary to use, solvent based inks with low VOC content should be selected and good ventilation conditions should be ensured.
Choose SuggestionsPrioritize environmentally friendly inks: In paper bag printing, the use of
water-based inks and other environmentally friendly inks should be given priority. These inks meet environmental standards and can reduce their impact on the environment and human health.
Choose ink according to printing requirements: If the paper bag needs to display exquisite patterns or colors and has high requirements for printing quality,
UV ink can be chosen. If the printing requirements are relatively low or cost reduction is needed, ordinary water-based ink can be chosen.
Considering the cost-effectiveness of ink: When choosing ink, in addition to considering its performance characteristics, it is also necessary to consider its cost-effectiveness. The prices of different grades of ink vary greatly, and the appropriate ink type should be selected according to the actual situation.
Pay attention to the storage and use of ink: Regardless of which ink is selected, it is necessary to pay attention to its storage and use conditions. The viscosity and dryness of ink are sensitive to changes in environmental temperature and humidity. It should be stored in a suitable environment and kept clean and functioning properly during use.
A high concentration, low viscosity water-based ink produced by Huizhou StarColor is particularly suitable for printing paper bags. Not only does the printed pattern have clear color and high glossiness, but it is also more environmentally friendly and safe. Welcome to your inquiry.
