Wet Strength Agent

I. Introduction

Wet strength agent is a key additive for papermaking. It enables paper to maintain strength and avoid disintegration when damp or immersed in water.

Main product: PAE resin (formaldehyde-free with optimal performance).

Main applications: paper cups, kitchen towels, food packaging paper, medical-grade paper.

II. Recent News (2025–2026)

Low-chlorine / chlorine-free PAE is mandatory for food packaging, phasing out high-chlorine products rapidly.

Recyclable and easily repulpable GPAM and bio-based wet strength agents represent emerging trends.

National standards have tightened environmental indicators, pushing the industry toward higher safety and greener development.
