Top Custom Biodegradable Plate Manufacturer in China

Why Choose Custom Biodegradable Plates

In recent years, with global “plastic bans” and the rise of green consumption, biodegradable plates have become the preferred eco-friendly alternative for catering, takeout, and retail sectors. For brands, custom biodegradable plates are not just a product choice—they reflect corporate social responsibility and brand image.

(1) Environmental Trends Drive Demand for Biodegradable Products
According to Statista, the global market for biodegradable tableware is projected to reach $9.5 billion by 2024, with an annual growth rate exceeding 8% over the next five years. As consumer awareness of eco-friendly materials grows, brands increasingly adopt corn starch–based biodegradable materials, which comply with food safety and compostability standards in different countries.

(2) Customization Enables Brand Differentiation
Custom plates allow freedom in shape, thickness, color, and logo design, and corn starch–based materials can be formulated for different purposes—for instance, enhanced for heat resistance in hot food packaging or optimized for rigidity in disposable tableware.

(3) Consumer Experience and Brand Value
Consumers pay attention to texture, odor, and safety when using biodegradable tableware. Guanzhong’s products are made from food-grade corn starch, which is odorless, grease-resistant, and smooth to the touch, enhancing user experience while building long-term trust in the brand.
