[New Product] Drip Absorbent Material for Food: "Water Absorbing Paper" (Water Absorption and Retention)
We obtained "water-absorbing paper" with a water absorption capacity of more than four times its own weight by using wood pulp, a forest resource, as the raw material and enhancing the swelling properties of the pulp fibers themselves!
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 a water absorption capacity of over four times that. 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, thereby enhancing its water absorption capacity. The water absorbed by "Water-Absorbing Paper" gradually evaporates and is released into the surrounding environment based on humidity, allowing it to 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
■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 the "Moisture Absorbing Paper" with water, it helps prevent the drying of fresh vegetables. The absorbed water does not remain in the paper fibers indefinitely but gradually evaporates, helping to maintain the freshness of the food. ■Condensation Water Absorption Inside Wrapping When wrapping moisture-rich foods with films, condensation occurs on the inner surface of the films, and that water can affect the food. With "Moisture Absorbing Paper," it absorbs the condensation water and gradually releases it as vapor into the surrounding environment, thereby protecting the freshness and quality of the food. *For more details, please feel free to contact us.*
