How to Choose Wet Strength Paper

Introduction

We consume a wide range of beverages every day — from juice and beer to milk and soft drinks. On hot summer days, when you grab a chilled bottle from the refrigerator, have you ever noticed that the label remains smooth and intact, even in a wet and humid environment? This durability comes from a specially treated paper known as wet strength paper.

Characteristics of Wet Strength Paper

The defining feature of wet strength paper is its ability to retain strength and structure even after direct exposure to moisture. Unlike ordinary paper, which quickly loses integrity when wet, wet strength paper maintains its mechanical properties, shape, and usability.

Other important characteristics include:

• Moisture resistance: Performs well even after being soaked, without tearing or disintegrating.
• Durability: Its chemically reinforced structure makes it resistant to wear, tear, and aging.
• Food safety compliance: When used in the food industry (such as tea bag paper or coffee filter paper), it must be manufactured with wet strength agents that meet international food contact safety standards.

Applications of Wet Strength Paper

Thanks to its moisture resistance and strength, wet strength paper is widely used in different industries:

Food and Beverage Packaging: Tea bags, coffee filters, and other food packaging applications.

Labels: Especially for beer bottles, juice bottles, and beverage containers stored in coolers or refrigerators, ensuring labels remain intact in cold, wet environments.

Tickets and Tags: Outdoor event tickets, luggage tags, and admission passes that must withstand rain and humidity.
