Environmentally friendly material "Plastic-free water-absorbing sheet (water-retaining paper)"
No use of plastic sponges or water-absorbing polymers. Achieved water absorption performance of over four times its own weight by improving the swelling properties of paper materials! This is an environmentally friendly product.
This is an environmentally friendly product that enhances the water absorption function of paper. While regular paper has a water absorption performance of about twice its weight, the new product "Water-Absorbing Paper" has over four times the water absorption capacity. Additionally, it has excellent water retention properties to hold the absorbed water. The mechanism works by allowing "Water-Absorbing Paper" to absorb and swell with water within the fibers themselves, as opposed to regular paper, which stores water in the gaps between wood fibers. The water absorbed by "Water-Absorbing Paper" gradually evaporates and is released into the surrounding environment, as if the paper is breathing, depending on the humidity, which helps maintain the freshness and quality of food. It is used in various fields, including the absorption of drips from fresh food and prevention of drying, primarily for freshness preservation. 【Features】 ● Made from wood pulp, it has high water absorption and retention properties. ● Excellent water absorption capacity for saline solutions. ● Does not use water-absorbing resins. ● Can be cut to any desired size. ● Can be printed on. 【Examples of Use】 ● Absorption of drips from fresh fish ● Absorption of condensation water inside packaging ● Prevention of drying for fresh vegetables ● Retention of various chemical solutions *For more details, please feel free to contact us.

Applications/Examples of results
■Absorption of Condensation Water Inside Wrapping When wrapped in films, condensation may occur on the inside or outside. With "water-absorbing paper," it can absorb condensation water and gradually release it as vapor into the surrounding environment, preventing water droplets and wetness. ■Drip Absorption for Fresh Fish While absorbing moisture, it retains water with its moisture retention properties. It helps maintain the freshness of ingredients such as fish and meat, which require freshness. Additionally, since it is made solely from paper materials, it can be safely used for food packaging. ■Prevention of Drying for Fresh Vegetables By pre-soaking "water-absorbing paper" with water, it helps prevent the drying of fresh vegetables. The absorbed water does not remain in the paper fibers indefinitely but evaporates gradually, helping to maintain the freshness of the food. *For more details, please feel free to contact us.*
