Rainy Season has come. How's Your Delivery Box Holding Up?
Every June brings not only a logistics peak for major e-commerce promotions but also concentrated rainfall across many parts of China. Mountainous piles of parcels inevitably face damp conditions during transportation and storage—cardboard boxes absorb moisture and soften, get damaged at edges and corners, and may even compromise the integrity of the contents. This year, Anhydrous Gypsum Packaging Boxes developed by Guizhou Phosphate Chemical Group are gradually making their way into the logistics sector. Could they become a game-changer for deliveries during the rainy season? Let’s take a look.
More than “Eco-Friendly”, meanwhile a practical choice
Many people still view eco-friendly packaging as plain-colored, low-strength and costly. In fact, the Anhydrous Gypsum Packaging Boxes from Guizhou Phosphate Chemical Group stand out in appearance, strength and practicality. Visually, they can be customized in color as required, with a smooth, clean surface and the distinctive texture of industrial products. Structurally, their compression and impact resistance are vastly improved compared with traditional cartons, delivering stable performance in real-world use. Trials in parts of China and overseas markets including Australia and Dubai have earned positive feedback from logistics companies and users.
Steady performance in humid conditions
As June arrives with rising humidity and frequent rain, traditional cartons easily absorb water, soften and deform, or even go moldy. The main raw material of Anhydrous Gypsum Packaging Boxes———Modified Anhydrous Gypsum——features low water absorption and excellent dimensional stability. Verified by professional institutions and on-site applications, the boxes maintain their shape and protective functions even in humid environments or after brief exposure to rain. For moisture-sensitive goods such as electronic products, dried goods, vegetables, fruits and seafood, they offer more reliable protection than ordinary cartons.
Unboxing a Green Initiative
Focusing only on their practical performance tells just half the story. The greater value of these boxes lies in the resource recycling cycle behind them. Phosphogypsum is an industrial by-product generated from phosphorus chemical production. After years of technical research, Guizhou Phosphate Chemical Group processes Anhydrous Gypsum into powder through high-temperature calcination or chemical crystal transformation, then composites it with polymer materials to produce eco-friendly boxes that can replace part of paper packaging.
Producing one ton of Anhydrous Gypsum Packaging Boxes saves approximately 800–1100 kg of wood compared with traditional wood-pulp cartons.
At present, Guizhou Phosphate Chemical Group has built a production facility with an annual capacity of 25,000 tons of Anhydrous Gypsum masterbatch and packaging boxes, one of China’s earliest large-scale production projects using this technical route. The products have passed testing and certification by SGS and other authorities, with all indicators meeting international standards.
A New Trend Taking Shape Guided by Policies
The revised Regulations on Express Delivery that took effect in 2025 explicitly encourages green, reduced and recyclable express packaging. Recently, Guizhou Post Administration took the lead in organizing a promotion event for phosphogypsum eco-friendly packaging products, where multiple delivery and courier companies held on-site negotiations and announced plans to promote the application of such packaging for suitable product categories. This means Anhydrous Gypsum Packaging Boxes are no longer just a corporate experiment, but gradually becoming a viable option in the green logistics system.
