What is wet strength paper used for?

Wet strength paper is a type of paper that is designed to maintain its strength and integrity even when it is wet. This is achieved through the use of special resins or chemicals that are added to the paper during the manufacturing process. Wet strength paper is commonly used for packaging products that will come into contact with liquids, such as tea bags, disposable cups, and paper towels. It can also be used for other applications such as filter papers, labels, and maps.

Wet strength paper is commonly used for packaging products that will come into contact with liquids, such as tea bags, disposable cups, and paper towels. It can also be used for other applications such as filter papers, labels, and maps. Some other examples of its usage are:


.Packaging for wet products, like frozen foods, or items that may be affected by dampness during storage or transportation.


.Tissue paper, sanitary products, baby wipes, etc.


.Labels, tags and maps that need to hold up to moisture, humidity, or exposure to liquids.


.Filter paper, utilized in labs and chemical industries where wet filtration is needed.


.Packaging for cleaning and chemical products that could cause the ordinary paper to lose strength or dissolve when wet.


What is high wet strength paper?

High wet strength paper is a type of paper that has been designed to maintain a high level of strength even when it is wet. This is achieved through the use of special resins or chemicals that are added to the paper during the manufacturing process. These resins or chemicals can be synthetic or natural, and the type used will depend on the desired properties of the final product.


The wet strength of the paper is usually measured by comparing the wet tensile strength (the amount of force required to break the paper when it is wet) to the dry tensile strength (the amount of force required to break the paper when it is dry). High wet strength paper will have a wet tensile strength that is significantly higher than its dry tensile strength, meaning it can maintain its strength even when it is wet.


High wet strength paper typically used for packaging and labeling products that are exposed to high moisture or liquid contact, such as, food packaging, beverage packaging, filter papers, paper towels and facial tissues, sanitary products, and also for industrial uses as filter papers in chemical industries, as well as in labs, etc.
