Explore the differences between bagasse and cornstarch food containers, and discover how caterers choose the best eco-friendly option for their needs.


In an era where environmental consciousness is at the forefront of consumer and industry priorities, foodservice providers are increasingly turning to sustainable disposable tableware. This article aims to guide the foodservice industry in choosing between two popular eco-friendly food container options: bagasse and cornstarch containers. We will explore their differences, benefits, and the factors that caterers should consider when making their choice.


What Are Bagasse Food Containers?

Bagasse food containers are made from the fibrous residue left after extracting juice from sugarcane. This material is repurposed to create a sturdy, biodegradable, and compostable alternative to traditional plastic containers.


The production process helps you to recognize the properties of bagasse containers:

1. Collection of Sugarcane Residue: After sugarcane is processed to extract juice, the remaining fibrous material, known as bagasse, is collected.

2. Cleaning: The collected bagasse is thoroughly cleaned to remove any impurities or residual sugars.

3. Pulping: The cleaned bagasse is pulped, breaking it down into a slurry of fibers.

4. Blending: The pulp is blended with water and binding agents to improve its moldability.

5. Molding: The mixture is molded into desired shapes using high heat and pressure to form sturdy containers.

6. Drying: The molded containers are dried to remove excess moisture.

7. Finishing: The dried containers are trimmed and polished to achieve the final product specifications.

What Are Cornstarch Food Containers?

Cornstarch food containers are derived from polylactic acid (PLA), a bioplastic made from fermented plant starch, typically from corn. Cornstarch containers are appreciated for their clarity, lightweight, and biodegradability.


The following is the production process for corn starch containers:

1. Extraction of Starch: Corn kernels are processed to extract starch.

2. Conversion to Sugars: The starch is hydrolyzed into simple sugars.

3. Fermentation: The simple sugars are fermented by microorganisms to produce lactic acid.

4. Polymerization: The lactic acid undergoes polymerization to form polylactic acid (PLA).

5. Pelletizing: The PLA is formed into pellets for easy handling and processing.

6. Extrusion: The PLA pellets are melted and extruded into sheets or molds to create containers.

7. Forming and Cutting: The extruded PLA is formed into container shapes and cut to size.

8. Finishing: The containers undergo final quality checks and finishing processes.
