Wet Strength Paper is a high-performance special paper that is processed by adding wet strength agents during the papermaking process, and undergoes special curing treatment. It retains high physical strength (tensile, tear, burst strength) even when fully wetted or soaked in water, which is the core feature distinguishing it from ordinary paper. It is divided into permanent wet strength paper and temporary wet strength paper according to water resistance durability, and is widely used in packaging, medical, daily chemical, food and other fields with water contact requirements.

Water-Resistant Wet Strength Paper is a high-performance specialty paper engineered for commercial operators and industrial manufacturers with water-contact operational needs. Produced by adding food-grade wet strength agents during the papermaking process and undergoing specialized curing treatment, this paper retains exceptional tensile, tear, and burst strength even when fully wetted or soaked in water – the core advantage that sets it apart from standard paper. It is categorized into permanent wet strength paper and temporary wet strength paper based on water resistance durability, delivering reliable performance across high-humidity, water-exposed scenarios.

Our waterproof wet strength paper maintains structural integrity even after full water immersion, drastically reducing packaging breakage, product spoilage, and after-sales complaint rates during transportation, storage, and end use, cutting your operational losses significantly.
It offers excellent compatibility with die-cutting, printing, and laminating processes, with stable chemical properties that resist oil, high and low temperatures. This makes it adaptable to frozen, refrigerated, and hot food service scenarios, eliminating the need for frequent material adjustments in your production line.
The food service wet strength paper complies with global food contact material standards, using non-toxic, food-grade raw materials with no harmful migration, helping you meet strict market access requirements and reduce regulatory risks.
It maintains stable performance during long-term storage in conventional warehouse conditions, resisting moisture deformation and adapting to automated packaging lines, boosting your production efficiency and reducing downtime.
Ideal for catering packaging liners, frozen food wrappers, beverage labels, fresh produce packaging, and disposable catering supplies, the wet strength paper for food packaging adapts to dry, wet, and oily food scenarios.
Suitable for disposable medical dressings, disinfectant wipe substrates, medical packaging, and hygiene products, meeting strict water resistance and safety requirements in medical scenarios.
Used for wet wipe packaging, cosmetic labels, cold chain logistics packaging, and outdoor transport labels, ensuring packaging integrity in high-humidity environments.
We provide fully customized water-resistant wet strength paper solutions for commercial enterprises, including tailored basis weight, roll width, wet strength type, surface treatment, and food-grade formula adjustments. Our flexible bulk supply system supports both small-batch trial production and large-scale mass production, with strict quality control to ensure batch-to-batch consistency and reliable global delivery to keep your production schedule on track.
Standard water-repellent paper only has surface water resistance, and loses all strength once the surface is damaged or fully soaked. Our wet strength paper retains high mechanical strength even when fully saturated, suitable for long-term water contact.
Yes, our food service wet strength paper meets global food contact safety standards, using food-grade raw materials with no harmful migration, suitable for direct contact with all food types.
We offer flexible MOQ adjusted to your specific specification needs, supporting both small-batch trials and large-scale mass production for commercial operators.
