Reasons Why Choose Cornstarch Packaging Instead of Single-Use Plastic Packaging

Our dependence on single-use plastic packaging has become a major environmental concern. However, a promising alternative is emerging: cornstarch, a type of plant-based packaging. This article will delve into the world of cornstarch packaging, exploring its creation process, lifecycle, and the advantages and disadvantages it presents. Ultimately, we will examine the compelling reasons why choosing cornstarch packaging can be a significant step towards a more sustainable future.

What Is Cornstarch Packaging?

Cornstarch packaging represents a novel approach to sustainable packaging solutions. It leverages polylactic acid (PLA), a bioplastic meticulously derived from the fermentation of plant starches, predominantly cornstarch. This innovative material offers functionality akin to traditional plastics, but with crucial distinctions:

  • Renewablity: In stark contrast to conventional plastics sourced from petroleum, cornstarch packaging relies on a renewable resource - cornstarch. This shift promotes a more sustainable material life cycle.
  • Biodegradability: Under appropriate industrial composting conditions, cornstarch packaging exhibits the remarkable ability to decompose. This stands in stark contrast to traditional plastics, notorious for their persistence in landfills for extended periods, often exceeding centuries.

The confluence of these characteristics’ positions cornstarch packaging as a compelling alternative for environmentally conscious consumers and businesses alike.

What Is Cornstarch Packaging?

How Is Cornstarch Packaging Made?

The production of cornstarch packaging leverages a biorefining process to convert readily available plant starches into a bioplastic material.

Here's a breakdown of the key steps:

  1. Starch acquisition: Cornstarch serves as the primary raw material.
  2. Fermentation: The starches undergo a controlled fermentation process, similar to yogurt production. This step utilizes microorganisms to convert the complex starches into simpler sugars.
  3. Polymerization: The resulting sugars are then transformed into polylactic acid (PLA) through a polymerization process. PLA essentially functions as the building block for the bioplastic.
  4. Pellet formation: The PLA undergoes a gentle heating process, followed by molding into uniform pellets.
  5. Thermoforming: Finally, the PLA pellets are reheated to a molten state and shaped into the desired final product forms, such as food containers or utensils.

This biorefining approach offers a significant advantage compared to traditional plastics derived from petroleum. Cornstarch, a renewable resource, forms the foundation of cornstarch packaging, promoting a more sustainable production cycle.

Lifecycle of a Cornstarch Packaging

Unlike traditional plastics, cornstarch food packaging boasts a lifecycle centered on renewable resources and potential biodegradation. Let's explore its journey from production stage to use stage and end-of-life stage.

  • Production Stage: The journey begins with corn, a plant grown from readily available seeds. The kernels are processed to extract starch, which then undergoes fermentation and other processes to transform into polylactic acid (PLA), the building block of corn starch packaging. Finally, the PLA is molded into desired shapes like food containers or utensils.
  • Use stage: During its use stage, the cornstarch packaging protects and contains the product, similar to traditional plastics.
  • End-of-life: This is where cornstarch truly shines. Ideally, used containers enter industrial composting facilities. Here, controlled heat and moisture create optimal conditions for microorganisms to break down the PLA into its natural components in just 180 days. This breakdown leaves behind organic matter that enriches the soil, promoting a circular economy.

Cornstarch food packaging offers a clear advantage in its potential biodegradability compared to traditional plastics that can last in landfills for centuries.

Advantages and Disadvantages of Cornstarch Packaging

Cornstarch food packaging has emerged as a promising alternative to traditional plastics, but like most innovations, it comes with its own set of advantages and disadvantages. They are explained as below.

Advantages

Corn starch packaging offers differents advantages, including:

  • Biodegradable and Compostable: Under ideal conditions, cornstarch food packaging breaks down through composting, significantly reducing landfill waste and its associated environmental issues.
  • Renewable Resources: Unlike traditional plastics derived from petroleum, cornstarch packaging relies on readily available and renewable resources like corn, promoting sustainability.
  • Reduced Carbon Footprint: Studies suggest the production of cornstarch packaging generally requires less energy compared to conventional plastic manufacturing.
  • Safe for Food Contact: Cornstarch packaging is generally considered safe for food contact, free from harmful chemicals commonly found in some traditional plastics.
  • Versatility: Cornstarch-based materials can be molded into various shapes, offering a viable option for diverse packaging applications, from food containers to utensils.

Disadvantages 

Beside the numerous advantages, there are still some disadvantages, including:

  • Limited Heat Resistance: Cornstarch packaging often struggles with high temperatures compared to traditional plastics. This limits its use in applications requiring heat tolerance, like hot food containers.
  • Composting Infrastructure Dependence: Optimal biodegradation relies on industrial composting facilities, which may not be readily available in all regions.
  • Potential for Land-Use Changes: Large-scale corn production for cornstarch packaging could lead to land-use changes or contribute to existing agricultural concerns.
  • Higher Cost: Currently, cornstarch food packaging might be more expensive than traditional plastic options due to evolving production processes.
  • Home Composting Limitations: While possible in some cases, home composting of cornstarch food packaging may be slower and less efficient compared to industrial facilities.

In brief, cornstarch food packaging offers a compelling alternative with its eco-friendly attributes. However, factors like composting infrastructure availability and potential agricultural concerns should be considered. So, should you choose packaging made from cornstrarch? We will explain the main reasons in the next section.

Reasons Why Business Choose Cornstarch Food Packaging Instead of Single-use Plastic

In today's environmentally conscious marketplace, businesses are increasingly seeking sustainable solutions. This shift has led many to favor cornstarch packaging over traditional single-use plastics. Here's a breakdown of the key reasons driving this trend:
