Wet strength paper finds a variety of applications in different industries. Here are some common uses and fields where wet strength paper is applied:

Food packaging: Wet strength paper is widely used in food packaging, particularly for items that require moisture resistance and protection. It is commonly used for packaging products like frozen foods, meat and poultry, confectionery, bakery items, and snacks. The paper's anti-permeability and moisture-proof properties help maintain the freshness and quality of the packaged food.

Beverage packaging: Wet strength paper is suitable for packaging beverages that may come into contact with moisture or require resistance to condensation. It is commonly used for beer labels, water bottle labels, wine labels, soft-drink labels, and other beverage containers. The paper's ability to retain its strength and integrity even when wet makes it a reliable choice for these applications.

Overall, wet strength paper's anti-permeability, moisture-proof properties, softness, and ability to retain strength in wet conditions make it suitable for packaging, labeling, filtration, and other applications where moisture resistance and durability are required.
