Kraft paper has become synonymous with eco-friendly packaging, widely used across industries for its strength, durability, and most importantly, its biodegradability. But what exactly makes kraft paper biodegradable, and how does it contribute to a more sustainable future?
In this blog, we’ll break down the science behind the biodegradability of kraft paper, explore how its production process influences its environmental impact, and why businesses worldwide are turning to kraft as a sustainable packaging solution.
What Does It Mean for a Material to Be Biodegradable?
Biodegradable materials are substances that can be broken down naturally by microorganisms, such as bacteria and fungi, into harmless byproducts like water, carbon dioxide, and biomass. These materials decompose over time without leaving harmful residues, which is crucial for minimizing environmental pollution.
Kraft paper, made from natural wood fibers, falls into this category because its organic components can be naturally decomposed, unlike plastic, which can take hundreds of years to break down.
The Kraft Process: Key to Biodegradability
The biodegradability of kraft paper begins with its production. Kraft paper is made using the kraft process, a chemical pulping method that converts wood into wood pulp. During this process, the lignin (the part of wood that makes it rigid) is separated from the cellulose fibers. The resulting pulp, made primarily of cellulose, is used to create kraft paper.
Since cellulose is a natural organic compound, it can easily be broken down by microorganisms in the environment. This is one of the core reasons kraft paper is biodegradable. Unlike other types of paper, kraft paper is often unbleached, which further enhances its biodegradability by avoiding the introduction of harsh chemicals that can slow down the decomposition process.

How Long Does It Take for Kraft Paper to Biodegrade?
The time it takes for kraft paper to biodegrade depends on several factors, including the environmental conditions, thickness of the paper, and exposure to moisture and microorganisms. Under ideal composting conditions, kraft paper can break down completely within 2 to 6 weeks.
This is a stark contrast to plastic packaging, which can take anywhere from 400 to 1,000 years to decompose. By using kraft paper, businesses can significantly reduce their contribution to landfill waste.
Kraft Paper and Composting
Because kraft paper is made from natural materials and does not contain synthetic chemicals, it is also compostable. Composting is an environmentally friendly way to dispose of biodegradable materials, where they are broken down into nutrient-rich compost that can be used to improve soil health.
In Australia, kraft paper is often included in green waste composting programs. The NSW Environment Protection Authority encourages businesses and households to compost biodegradable materials like kraft paper as part of their strategy to reduce landfill waste.
Unbleached Kraft Paper: The Purest Form of Biodegradable Packaging
Unbleached kraft paper is the most eco-friendly version of kraft paper. Because it does not undergo the bleaching process, it retains its natural brown color and remains free from chlorine and other harmful chemicals that could hinder its biodegradability.
Unbleached kraft paper is a preferred option for businesses seeking to reduce their environmental footprint. It’s often used in eco-friendly product packaging, food packaging, and retail bags. The Australian Government’s National Waste Policy emphasizes the use of recyclable and compostable materials like unbleached kraft paper as part of their broader waste reduction goals.
Why Kraft Paper is Better Than Plastic
One of the primary reasons businesses are moving towards kraft paper is the significant difference in environmental impact compared to plastic. While plastic packaging is durable, it takes hundreds of years to decompose, contributing to pollution and damaging ecosystems.
Kraft paper, on the other hand, naturally breaks down within a few weeks. Its biodegradability helps to reduce waste in landfills and oceans, making it an excellent alternative for companies looking to minimize their environmental impact.
How Businesses Are Using Kraft Paper for Sustainable Packaging
Many businesses in Australia have already switched to kraft paper products for their packaging needs. Retail stores, food outlets, and e-commerce businesses are increasingly using kraft paper bags, wrapping, and boxes to align with the growing demand for sustainable solutions.
For example, cafes and restaurants are opting for kraft food packaging for takeaway meals, replacing plastic containers with eco-friendly alternatives. Retail stores are offering kraft paper bags to customers instead of plastic, helping to reduce single-use plastic consumption.
One such case study is that of BioPak Australia, which offers kraft-based packaging products and emphasizes their compostable nature. Their kraft paper packaging has helped businesses significantly reduce their reliance on plastic and meet growing consumer expectations for eco-friendly solutions.
Environmental Benefits of Using Kraft Paper
1. Reduces Landfill Waste: Since kraft paper decomposes quickly, it reduces the amount of waste that ends up in landfills.
2. Lowers Carbon Footprint: The production and disposal of kraft paper generate fewer greenhouse gases compared to plastic, contributing to a lower carbon footprint.
3. Supports Circular Economy: Kraft paper can be recycled multiple times before its fibers become too short, supporting the concept of a circular economy where materials are reused rather than discarded.
4. Compostable: Kraft paper can be composted along with organic waste, returning nutrients to the soil.
Why Choose Kraft Paper for Biodegradable Packaging
Kraft paper’s biodegradability, strength, and versatility make it an excellent choice for businesses looking to switch to more sustainable packaging solutions. Its ability to naturally decompose and its compatibility with recycling and composting systems help reduce environmental impact and promote a greener future.
