Sustainable packaging is a strategy used by businesses to lessen their environmental impact. It consists of using packing materials and methods that reduce harm on the environment compared to standard options.

Although the use of standard packaging methods has dramatically decreased, traditional plastic packaging is still prevalent and has significant impacts on the environment. The majority of plastics are made from polymer-based fossil fuels, which are non-renewable resources, and take many decades or even centuries to decompose.

Once plastic packaging becomes waste, it will decompose and release microplastics, and leach contaminants into the soil and water. A lot of this waste can make its way to the ocean and affect ecosystems and wildlife. The production of standard plastics takes a lot of energy and can create CO2 and other pollutants.

With the growing concern for these issues, there is a growing interest in sustainable packaging. The Packaging Market is expected to reach USD 1.41 trillion by 2032, according to GMI Research.

What are the Materials used in Eco-Friendly Packaging?

There is no dominant material for eco-friendly packaging. It depends on the product, how much protection is needed, costs, and how the packaging will be disposed of.

Some of these options include recycled paper and tissue, corrugated cardboard, kraft paper, bioplastics, and plant-based packing peanuts.

PHAs (Polyhydroxyalkanoates) and PLA (polylactic acid) are examples of bioplastics being researched for use in packaging as alternatives to petroleum-based plastics. The environmental impact of these bioplastics depends on their production and waste disposal methods, so the entire lifecycle of the packaging must be considered.

Some sustainable packaging materials are designed to be compostable. Composting can happen at either an industrial or a home level, depending on the material and local facilities. Some PHA-based materials can fully compost in less than half a year.

What Are Some Sustainable Packaging Ideas?

There are packages made from bioplastics and recycled paper, but there are other interesting and novel sustainable packages that reduce waste and offer added value to customers.

Some examples are:

• Mailers and Envelopes: Packaging made from bioplastics can be used to eliminate the use of single-use plastic packaging for delivery.
• Seed Packaging: Packaging can be designed to have a second use by growing plants and fostering biodiversity.
• Reusable Packaging: Packaging can be designed to be used and kept for multiple deliveries, as opposed to single-use packaging.

The right package for your product is something that still needs to be experimented with. Packaging must be effective in protecting the product, and there should be a consideration for use of unnecessary materials.

How Should Small Businesses Implement Sustainable Packaging?

Small businesses may be cautious about the costs associated with sustainable packaging. Companies with thin profit margins are understandably concerned with additional expenses.

There are ways to make this change more manageable. One of those ways is to choose packaging with a lower volume for storage. Packaging that reduces the volume of packaging needed can reduce the size of the warehouse and control storage costs.

Another option is to use a packaging system that is either reusable or recyclable. Examples of recyclable packaging materials include incentivizing customers to return the packaging or setting up a collection point to gather the packaging for reuse or recycling.

This can make a company's packaging process more sustainable while gradually transitioning away from less sustainable packaging.

What are the Most Innovative Eco-Friendly Food Packaging Ideas?

Packaging for food has the potential to have a large positive impact when sustainable packaging options are widely adopted. Food packaging has to protect the quality and safety of the food, which means not all packaging for food can be as sustainable as we’d like it to be.

There are plenty of options for packaging that have interesting and innovative solutions.

Seaweed and Algae-Based Packaging

Seaweed and algae-based packaging is being researched as an alternative for food packaging. Because some seaweed and algae can be edible, this has the potential to drastically reduce packaging waste.

Cornstarch-Based Films and Bioplastics

Packaging for food can also be cornstarch-based films and bioplastics. Plant-based packaging can replace a range of packaging products derived from petroleum if the desired performance of the packaging is met.

The major concern is that sustainable packaging is more complex than swapping materials. Packaging consists of a multitude of factors including the sources of the materials, how much is used, the performance of the materials during transport, and the post-use infrastructural requirements.

Importance of Sustainable Packaging

Packaging touches almost every aspect of the product lifecycle from manufacturing to disposal. This creates an opportunity for significant impact from the subsequent, and often times easy to implement, design changes.

There are numerous methods to increase the sustainability of packaging including, but not limited to, using less material, sourcing packaging made with recycled or renewable materials, improving the efficiency of packaging, and promoting the reuse or more expedient packaging recycling.

This package of design changes creates an opportunity for an improved sustainability balance for businesses. Greater protection of the product, higher satisfaction for the end-user, and greater profitability for the business can all be gained with the use of sustainable packages. This balance will become even easier to achieve with the continued development of packaging technology and sustainable materials.
