Manufacturing Process

Primary Mixing Phase

  1. Combine sugarcane bagasse and ground bamboo fiber in a large industrial mixer.
  2. Gradually add water at 50°C to ensure even distribution, mixing for 30 minutes.
  3. Monitor fiber dispersion using a sieve test to confirm uniform size and consistency.

Binder Addition Phase

  1. Slowly incorporate the starch binder into the fiber mixture.
  2. Maintain a temperature of 40°C, ensuring even distribution by mixing for an additional 20 minutes.
  3. Conduct a viscosity check to ensure proper binding characteristics.

Additives Integration Phase

  1. Introduce natural additives, ensuring they are evenly distributed across the mixture.
  2. Continue mixing at a lowered temperature of 30°C for 10 minutes.
  3. Verify antimicrobial distribution using sample microbial growth tests.

Molding and Curing Phase

  1. Transfer the homogenized mixture into trays using an automatic molding machine.
  2. Heat press each tray at 80°C for 5 minutes to achieve desired shape and firmness.
  3. Allow trays to cure under controlled humidity (30%) to ensure dryness and stability.

Usage Instructions

Use trays to package fresh vegetables and fruits, ensuring trays are dry and intact before placing produce. Trays can be customized in size and shape for various types of produce packaging.
