Water-based lamination technology is a new green choice for kraft paper bags

Kraft paper bags are widely used in many industries such as food, agricultural products, and daily chemical products due to their environmentally friendly and degradable characteristics. However, their natural paper materials are relatively fragile in the face of humid environments, and it is difficult to meet the high requirements of some products for moisture-proof and waterproof performance. For this reason, water-based lamination technology, as an innovative solution, is gradually becoming a new favorite for moisture-proof and waterproof treatment of kraft paper bags.
Advantages of water-based lamination technology
The use of water-based environmentally friendly glue as an adhesive is the technical point of water-based lamination technology, which is a process of covering the surface of kraft paper bags with a layer of transparent plastic film. Compared with traditional oily lamination and hot-pressed pre-coated film, water-based lamination has significant advantages:
Environmental protection and pollution-free: Water-based lamination glue uses water as a dispersant, does not contain toxic and harmful organic solvents, reduces VOCs (volatile organic compounds) emissions, and is more friendly to the environment and the health of operators.
High efficiency and energy saving: Since there is no need for heating and drying equipment, the water-based lamination process greatly reduces energy consumption and improves production efficiency. While quickly laminating, the quality and stability of the laminating products are guaranteed.
High gloss and good aesthetics: The surface of the kraft paper bag after water-based lamination is smoother and brighter, with bright colors, which enhances the visual effect and grade of the product.
Significant moisture-proof and waterproof effect: The formed plastic film protective layer can effectively isolate moisture and humidity, protect the products in the bag from moisture, and extend the shelf life of the products.
