Our Grinding Technology

2000-Mesh Ultra-Fine Grinding Process

Our disposable 3-compartment bamboo lunch box utilizes industry-leading ultra-fine grinding technology. The core manufacturing process—spanning the entire journey from raw bamboo material to finished product—is conducted entirely without the use of chemical additives.

Eco-Friendly Process:

Raw Material Selection: We select fresh Moso bamboo that is free from mold and insect infestation. Immediately following harvest, the bamboo undergoes a low-temperature drying process, being continuously dried for 48 hours in an environment maintained at 60–80°C to reduce its moisture content to below 8%, thereby ensuring the purity and stability of the raw materials.

Ultra-Fine Grinding:

Using specialized micro-pulverizing equipment, the bamboo material is ground to a fineness of 2000 mesh (D90 ≤ 6μm). This significantly exceeds the industry's conventional standard of 200–1200 mesh, enhancing the fineness of the bamboo powder by over 30% and laying a solid foundation for the subsequent molding stage.

Bio-based Granulation:

The 2000-mesh bamboo powder is blended with eco-friendly additives—such as natural plant starch and cellulose ethers—and processed through a twin-screw extruder to produce "Bamboo Bio-granules." These granules boast a uniformity rate of 99%, making them perfectly suited for automated injection molding processes.

Precision Molding:

We employ a high-temperature, high-pressure compression molding process (180–220°C) to create a seamless, one-piece structure featuring three compartments and secure sealing grooves. The edges are free of burrs, and the finished product is completed following trimming, sterilization, and coating treatments. The entire process strictly adheres to FDA and LFGB food-contact safety standards.

FAQ

What are the degradation conditions for the Disposable Bamboo Lunch Box?

The product is made from 100% biodegradable bamboo material; it can fully degrade within 175 days in various environments, including natural compost, soil, and marine settings.

What is the heat resistance limit of the Bamboo Compartment Lunch Box? Can it be microwaved?

The temperature resistance range is from -30°C to 130°C. It can hold hot soups and dishes, and can be placed directly into a microwave for heating (removing the lid is recommended). It is also suitable for refrigeration to keep food fresh and does not release any harmful substances.

Do you support customization? What is the Minimum Order Quantity (MOQ)?

As a leading source factory for disposable tableware in China, we offer comprehensive customization options (including specifications, logos, packaging, and set combinations). The MOQ for customized items varies depending on specific requirements (e.g., an MOQ of ≥10,000 sets for logo engraving). We also support small-batch trial orders to help minimize purchasing risks for our clients.

Does the Bamboo Compartment Lunch Box have any surface burrs or rough edges? Does it meet food contact safety standards?

The product has obtained various international and domestic food contact safety certifications—including CE, REACH, RoHS, TÜV Rheinland (Germany), and SGS (US FDA)—and contains no chemical residues, making it safe for use by both the elderly and children.

Compared to PLA and pulp-based meal boxes, what are the advantages of bamboo bio-based meal boxes?

① Superior Heat Resistance: Bamboo bio-based meal boxes can withstand temperatures up to 130°C—far exceeding the 60°C limit of PLA and the 80°C limit of pulp—making them ideal for holding hot food.
② Higher Hardness: Hardness is increased by 35%, making the boxes less prone to deformation or breakage, resulting in a longer service life.
③ Faster Degradation: They degrade within 175 days in natural environments, whereas PLA requires industrial composting conditions, and pulp-based products tend to soften when exposed to moisture.

What certifications are required to export these products to the EU and the US?

Exporting to the EU requires CE certification and REACH test reports; exporting to the US requires FDA certification and FDA food contact test reports. We can provide a complete set of export qualifications and test reports to assist our clients in clearing customs smoothly.

Can the product be reused?

Although designed as a single-use product, its high material hardness—combined with water- and oil-resistant properties—allows for 3 to 5 reuses if cleaned properly (using warm water and a neutral detergent, while avoiding abrasion by hard objects). This makes it suitable for non-disposable, high-frequency applications—such as daily household use or corporate group dining—thereby further reducing environmental costs.
