AI Technical Summary

Technical Problem

Existing fiber-based products are insufficient in terms of barrier properties against oil, water, vapor and oxygen, making it difficult to compete with plastics. Furthermore, the production process is cumbersome and costly.

Method used

By using cationic emulsion polymers and alkyl ketene dimers (AKD) to improve fiber raw materials, fiber-based products are produced through molding processes, thereby improving dryness and reducing Cobb value.

Benefits of technology

The produced fiber-based products have high dryness and low Cobb value, good barrier properties, and are biodegradable, making them suitable for a variety of packaging and container applications.
