Bamboo powder substrate sheet extrusion production line (a sheet production line that crushes and powders bamboo to use as the base material, then adds additives in specific proportions to produce standardized sheets used for thermoforming to manufacture disposable packaging products such as bowls, plates, lids, cups, trays, containers, etc.)
What is a Bamboo Powder Sheet Extrusion Line?
A ​100% biodegradable Bamboo powder sheet extrusion line is an advanced manufacturing system. It transforms bamboo powder into fully compostable sheets using a core ​bamboo powder sheet making machine, typically a twin-screw extruder. This machine mixes bamboo powder with biodegradable polymers (e.g., PLA/PBAT) and melts the blend. The molten material is then extruded through a flat die to form a continuous sheet. After precision cooling and calibration via rollers, the sheet is wound into rolls. This integrated ​100% biodegradable Bamboo powder sheet extrusion line automates production for eco-friendly packaging and tableware.
Advantages of 100% Biodegradable Bamboo-Based Sheet:
Sheets made on a ​bamboo powder sheet making machine offer critical environmental benefits. Their ​100% biodegradability ensures complete breakdown into harmless organic matter in industrial compost (per EN13432/ASTM D6400), eliminating microplastics. Bamboo’s fast growth makes these sheets highly renewable with a low carbon footprint—outperforming fossil-fuel plastics. The material also provides versatile performance: good strength, rigidity, and barrier properties for demanding uses like food packaging. Using a ​100% biodegradable Bamboo powder sheet extrusion line lets manufacturers meet eco-regulations and rising global demand for sustainable alternatives.

Solution Of 100% Biodegradable Bamboo Powder Sheet Extrusion Line:
The bamboo powder sheet production line consists of five parts: extrusion, calendaring, cooling, traction, and winding. (The material is extruded through an extruder, filtered and extracted, then calendared, cooled, shaped, and finally rolled onto rolls of specified dimensions.) The main components are made from high-quality materials with wear resistance and high-temperature resistance, processed using special techniques. The line utilizes a high-strength screw and high-precision molds, along with calendaring rollers featuring a special internal spiral channel, resulting in sheets with uniform thickness and high gloss.
