Take away food packaging refers to packaging materials made from corn starch or modified corn starch. It is a type of bioplastic that is derived from renewable resources such as corn kernels. The starch is extracted from the corn and processed to create a material that can be used for packaging applications.

How is Cornstarch Packaging Made?

Corn starch packaging is made through a process that involves extracting starch from corn and transforming it into a plastic-like material. Frist, corn kernels are harvested from corn plants, usually in large-scale agricultural operations. The harvested corn kernels are processed to remove the outer husk and germ, leaving behind mainly the starchy endosperm. Then, the starchy endosperm is ground into a fine powder and milled to break it down further. This creates a corn starch powder with fine particles. The corn starch powder is mixed with water to create a slurry. The slurry is then passed through a series of centrifuges or sieves to separate impurities and separate the starch from the remaining components. After that, the separated starch is usually wet at this stage and needs to be dried. It is typically passed through a drum dryer or air drying system to remove moisture and create a dry corn starch powder. In some cases, the corn starch may undergo modification through chemical or physical processes to enhance its properties. For example, modifications can be done to increase the material's heat resistance, flexibility, or strength.The dried and potentially modified corn starch powder is then typically mixed with plasticizers, additives, and water to create a slurry or paste. This mixture is then fed into an extrusion or molding machine, where heat and pressure are applied to shape the material into desired forms like films, containers, or packaging products. Once shaped, the corn starch-based material is cooled to solidify and retain its form. The cooling process may involve passing the material through water or chilled rollers.

Corn Starch Based Materials Packaging Types

Corn starch food packaging is typically used as an alternative to traditional packaging materials like plastic. It can be molded into various shapes and forms, such as containers, bowls, trays, plates, cups, bags, and wrappers. It is often transparent or translucent, making it suitable for showcasing the contents of the package.

Benefits of Corn Starch Packaging

Renewable: Corn starch is derived from corn, which is a renewable resource. Unlike traditional packaging materials like plastic, which are made from fossil fuels, corn starch packaging utilizes a natural and sustainable resource.

Biodegradable: Biodegradable corn starch packaging, meaning it can break down and decompose over time. This reduces the amount of waste that ends up in landfills and minimizes the environmental impact of packaging materials.

Reduced carbon footprint: The production of corn starch packaging typically requires less energy compared to traditional packaging materials. This results in a lower carbon footprint and helps reduce greenhouse gas emissions.

Source reduction: Corn starch packaging can be molded into various shapes, making it versatile for different packaging needs. This ability to customize packaging reduces the amount of material required, leading to source reduction and less overall waste.

Non-toxic: Corn starch is a safe and non-toxic material, making it a suitable alternative to plastic packaging, which can leach harmful chemicals into the environment. Corn starch packaging is often food-grade and can be safely used for packaging edible products.

Compostable: Corn starch packaging can be composted, either in industrial composting facilities or in home composting systems. This allows the packaging to be returned to the soil as organic matter, reducing waste and potentially improving soil health.

Importance of Switching To Cornstarch Packaging

The importance of switching to corn starch packaging lies in its positive impact on the environment, meeting consumer demand, complying with regulations, building brand reputation, and showcasing industry leadership. By making this switch, you contribute to a more sustainable future while reaping the benefits of responsible business practices.

Corn starch packaging is considered a more sustainable and eco-friendly alternative to traditional packaging materials, as it utilizes renewable resources and offers biodegradability and compostability.
