Aqueous Coating Paper

Specific applications of Water-based coated paper in the food industry

Food packaging bags: Water-based coated paper is widely used to make various food packaging bags, such as bread bags, snack bags, candy bags, etc. The water-based coating can effectively improve the water resistance and oil resistance of the paper, prevent the moisture or grease of the food from penetrating to the outside of the packaging, and maintain the freshness of the food. This coating can also increase the strength of the paper bag, making the packaging bag less likely to break during transportation.

Application examples:

Bread and pastry packaging: used to package fresh bread, cakes and biscuits, etc., water-based coated paper can prevent grease penetration and keep the packaging appearance neat.

Ready-to-eat food packaging: such as potato chips, popcorn, etc., water-based coated paper improves the moisture resistance and sealing of the packaging, which helps to extend the shelf life of the food.

Takeaway packaging boxes: With the rapid development of the takeaway industry, water-based coated paper is also used in food takeaway packaging boxes. Whether it is hot meals, cold meals or drinks, water-based coated paper can effectively resist the intrusion of external moisture and oil, keeping the takeaway food clean and tidy. It can also help maintain food temperature and prevent food from spoiling due to packaging problems.

Application examples:

Fast food boxes and bento boxes: Water-based coated paper increases the oil resistance and heat resistance of food packaging boxes, can maintain the temperature of hot food, and prevent grease penetration.

Takeaway beverage cups: Beverage cups made with water-based coated paper not only prevent liquid leakage, but also have good moisture resistance, which can effectively protect the packaging from moisture.

Frozen food packaging: Frozen food requires special packaging materials to resist low temperatures and prevent water evaporation. Water-based coated paper is very suitable for frozen food packaging due to its strong moisture resistance and cold resistance. The coating can effectively prevent the loss of water in frozen food and keep the food moist and fresh.

Application examples:

Quick frozen vegetable packaging: Water-based coated paper has waterproof and moisture-proof properties, which can effectively keep frozen vegetables fresh and prevent packaging damage.

Ice cream packaging: Water-based coated paper is also used for ice cream packaging, which can prevent water vapor condensation during the packaging process of ice cream and keep the packaging dry and clean.

Food labels and hangers: Labels and hangers on food packaging need to be not only beautifully printed, but also water-resistant, oil-resistant, and stain-resistant to cope with various food environments. Water-based coated paper provides excellent printability and anti-staining properties, ensuring that the information on the label is clearly readable for a long time and is not easily affected by moisture, grease, or food residues.

Application examples:

Juice and beverage bottle labels: Labels made of water-based coated paper are waterproof and oil-resistant, keeping the information clear in a humid environment.

Condiment and sauce bottle hangers: Labels made of water-based coated paper are suitable for condiment packaging, can resist grease contamination outside the bottle, and maintain the clarity of the brand image.

Paper cups and paper trays: Water-based coated paper is also commonly used in the manufacture of paper cups and paper trays, especially when it is necessary to avoid direct contact between drinks and food and packaging. The water-based coating prevents liquid from penetrating the outside of the paper cup, keeping the paper cup dry and strong, and also improves the moisture resistance of the paper tray.

Application examples:

Beverage cups: such as coffee cups, juice cups, etc., water-based coatings can not only enhance the water resistance of paper cups, but also avoid packaging damage caused by moisture.

Fast food trays: provide good moisture resistance, which can prevent the bottom of the tray from softening due to moisture in the food.

Advantages of water-based coated paper in the food industry

Environmental protection: Water-based coated paper uses water as a solvent, avoiding the volatile organic compounds (VOCs) used in solvent-based coatings. This environmental protection feature makes water-based coated paper more in line with the environmental protection and safety requirements of modern food packaging.

Safety: Water-based coated paper does not contain harmful chemical ingredients and can be directly in contact with food to ensure that it does not cause pollution or harm to food and meets the safety standards of food packaging.

Improve packaging functionality: Water-based coated paper can improve the water resistance, oil resistance, wear resistance and stain resistance of packaging, effectively extend the shelf life of food and protect food from the influence of the external environment.

High-quality printing effect: Water-based coated paper has good printing suitability, can provide clear and bright printing effects, enhance the visual effect of packaging, and attract consumer attention.

Water-based coated paper is increasingly used in the food industry. With its environmentally friendly, safe and powerful features, it has become an ideal choice for food packaging materials. Whether it is used for daily food packaging, takeaway packaging, frozen food packaging, or for food labels and hangers, water-based coated paper can provide superior performance and meet the high standards of modern consumers for packaging materials.
