In the egg industry, packaging is more than just a container; it is a critical component of the cold chain and shelf-life management. While plastic and heavily coated alternatives focus on being "waterproof," straw pulp technology focuses on something far more important: The micro-climate of the egg.

The Science of Vapor Exchange Eggs are naturally porous. As they age, they release moisture and carbon dioxide. In a non-breathable environment (like plastic), this moisture can condense on the shell, creating a breeding ground for bacteria and mold.

Our straw pulp cartons are engineered to provide a "breathable barrier." The natural fibers allow for consistent air exchange, ensuring that the egg stays dry and cool, which is essential for maintaining internal quality and food safety standards.

Superior Performance Under Stress: The Moisture Absorption Test We recently put our straw pulp trays to the test to see how they handle liquid spills—a common occurrence during transit or in-store mishaps.

As demonstrated in our latest laboratory test, when egg liquid is introduced:

Surface Tension Management: The carton effectively absorbs the liquid into the fiber matrix rather than letting it pool and contaminate neighboring eggs.

Structural Retention: Unlike standard recycled paper which can become "mushy," our straw pulp maintains its rigid structure.

Anti-Leak Base: Even after several hours of saturation, the bottom of the tray remains dry and structurally sound, preventing the "bottom-drop" failure common in lower-quality molded pulp.

Why Professional Producers are Switching For large-scale producers, the "grit" and natural texture of straw pulp represent high-performance engineering. It provides the necessary friction for automated packing lines while offering the cushioning needed for long-distance transport.

The balance of breathability, cushioning, and controlled absorbency makes straw pulp the gold standard for primary egg packaging. It doesn’t just hold the egg; it protects its biological integrity.
