Is the green production capacity of Rosinpack corn starch fully biodegradable plant tray implemented?

With the implementation of the domestic dual carbon policy and the introduction of disposable agricultural plastic restrictions in many countries around the world, corn starch seedling trays have become an essential product in horticulture, facility agriculture, and cross-border horticulture. The Rosinpack packaging factory based in Guangzhou ,zengcheng.has completed the upgrade of its starch modification production line, and the new corn starch fully degradable plant tray has been put into mass production. From raw material modification, integrated molding, to performance testing, the entire chain is self-developed, filling the gap in large-scale environmental protection seedling tray production capacity in South China. It can provide one stop customized degradation tray solutions for large greenhouse bases, cross-border horticultural brands, and vertical hydroponic farms in China.

Industry background: Degradable seedling trays usher in an explosive window period

1. Domestic policy driven: The control of plastic pollution during the 14th Five Year Plan period continues to deepen, and many greenhouse parks and seedling bases are gradually phasing out non degradable PP/PS plastic plug trays. Degradable seedling raising equipment is included in the category of agricultural support and promotion, and the annual growth rate of starch based seedling consumables exceeds 12%. By 2026, the market size of biodegradable horticultural trays will exceed 5.3 billion yuan, with corn starch substrates accounting for nearly 47% of the biodegradable tray market share due to their easy availability and complete composting advantages.
2. Overseas compliance pressure: The EU PPWR packaging regulations officially came into effect in August 2026, and California in the United States introduced new regulations for agricultural plastics. Traditional plastic seedling trays are restricted from export, and corn starch trays with OK Composite and FDA environmental certifications have become standard sources for foreign trade. Orders from horticultural buyers in Japan, South Korea, Southeast Asia, and North America have been increasing year by year.
3. Transformation of planting demand: Large scale farms and hydroponic bases for sprouts and seedlings prioritize the use of starch trays that can be directly degraded into the soil, saving labor costs for tray removal and waste plastic recycling. Transplanting does not damage the roots, significantly reducing overall planting costs.

Key Highlights of Rosinpack Factory Production | Our self-developed corn starch plant tray production line

Rosinpack has been deeply involved in vacuum forming packaging in Guangzhou for more than ten years. The original plastic seedling tray, 1020 flat tray, and 18 grid split hole tray have been matured and mass-produced. This time, a modified corn starch biodegradation automated production line has been added, which connects the entire process from modified corn starch mixture to finished product vacuum forming. The advantages of the factory have been implemented:

Self developed and modified raw materials, with performance comparable to traditional plastic pallets

• Under normal temperature greenhouse water and fertilizer environment, it can withstand water for 30-60 days to meet the requirements of full cycle seedling cultivation;
• The rigidity of the finished product meets the standard and can be planted, transported, and stacked on a mechanized assembly line;
• After being abandoned, the soil will naturally compost and fully degrade within 6-12 months, with no residual microplastics and organic matter feeding back into the soil.

Customized production for all categories, compatible with all specifications of seedling products

The new production line can mass produce a full range of plant trays: 1020 hydroponic flat tray, 18 grid seedling tray, multi specification sprout cultivation tray, flower cutting seedling bowl; Support full customization of size, thickness, bottom opening, color, and logo printing. Starch ratio can be adjusted as needed to adapt to two major scenarios: dryland seedling cultivation and hydroponic planting.

Environmentally friendly production with zero pollution, full chain green manufacturing

The entire starch tray production line produces no harmful waste gas or wastewater, and 100% of the corner starch materials are recycled and blended for production, which meets the standards of a circular factory. From the production end to the use end, it achieves low-carbon throughout the entire life cycle, and the carbon footprint of the tray is reduced by more than 62% compared to traditional plastics.

Core advantages of corn starch plant tray products

1. Direct planting without removing the tray: After seedling cultivation, there is no need to remove the tray, and the tray is directly buried in the soil for natural degradation, preventing root breakage during transplantation. The survival rate of seedlings is increased by 15% to 20%, saving the cost of manual tray removal.
2. Dual properties of breathability and water retention: The starch substrate has its own fine pores, which can balance breathability and water retention, reducing root rot and sudden collapse diseases. It is suitable for the cultivation of wheat grass, lettuce, melon and fruit seedlings, and succulent flowers.
3. Fully degradable and residue free: Both natural soil and industrial composting environments can be completely degraded without producing white waste, perfectly meeting the standards of organic farming and ecological horticultural planting.
4. Multiple scene structures are available for selection: the non porous water storage model is suitable for hydroponic seedlings, the guided hole model is suitable for soil cultivation seedlings, and the same mold can flexibly switch between opening schemes.
5. Safe food grade raw materials: free of BPA and plasticizers, sprouts and ready to eat vegetable seedlings are safe and compliant, meeting domestic and international food contact material standards.

FAQ

1.Can it be made to the same specifications as the original plastic socket? Do you support small batch sampling?

Full specification mold customization, mature molds such as 18 grid hole discs and 1020 flat discs are available in stock. A small number of samples can be produced within 2 days, and the size and aperture can be adjusted as needed for mass production.

2.Export requires environmental certification. Can factories provide supporting qualification documents?
Rosinpack corn starch tray can provide a complete set of OK Composite (EN13432), ROHS, and FDA testing reports to meet the import customs clearance audits of the European Union and North America.
