Coating Technology And Application Of Kraft Paper

Kraft paper coated product is a process that enhances the water resistance and wear resistance of kraft paper. This process involves bonding a layer of transparent polyester or polyethylene film onto the surface of kraft paper, providing it with advantages such as waterproofing, stain resistance, and wear resistance. At the same time, it also has good thickness and hardness, ensuring the long-term service life of the product. Suzhou Yisheng has been specializing in producing kraft paper coated products for 15 years, customized according to customer requirements. The width of the coated products can reach 2.6 meters, while the industry's average width is 2 meters. As a leader in the industry, let me introduce the process, application range, and product advantages of coated kraft paper for your reference.

The production process of kraft paper coating can be divided into the following steps:

The first step is to first place the kraft paper in an oven for degreasing treatment to remove fat and impurities from the surface of the kraft paper, in order to ensure better film coating effect.

The second step is to place the treated kraft paper on a specialized coating machine, place polyester or polyethylene film on the surface of the kraft paper, heat it, and then press it together.

The third step is to wait until the leaching is completed before proceeding with drying treatment. This step is very important, as the drying time and quality directly affect the effectiveness of kraft paper coating.

The fourth step is to carry out subsequent processing procedures such as rewinding and slitting to ensure that the final product meets the requirements.

Kraft paper coated products are suitable for various fields such as packaging, books, labels, etc. They are commonly used in the production of waterproof, moisture-proof, and product protection packaging materials for outer packaging boxes, folders, and industrial products. Various colors and printing services can be customized according to customer needs. It can also be applied to places such as kitchens and bathrooms that require waterproofing, reducing people's home maintenance costs and avoiding problems such as friction and water leakage during product use.

The advantages of kraft paper coated products mainly include the following:

1. Waterproof and stain resistant, avoiding contamination of kraft paper;

2. Enhance the hardness and thickness of kraft paper, and increase the product's service life;

3. Prevent product wear and tear during transportation and use, ensuring a beautiful appearance;

4. Prevent dust from entering the product and maintain internal cleanliness.

Overall, kraft paper coated products are a new type of product that is reprocessed and improved on the basis of traditional kraft paper processes. Its emergence has changed the limitations of traditional kraft paper products, solved the problems of waterproofing, stain resistance, and brought convenience to people's daily life and work, and has a wide range of application prospects.
