sustainable packaging design - eco friendly

You've likely seen news coverage of plastic packaging floating on the surface of the world's oceans. Experts predict that there will be more plastic than fish in the seas by the year 2050. 

Pollution is a driving force behind the sustainable packaging movement. Consumers are demanding green packaging solutions now more than ever and it's up to the packaging industry to deliver. 

Here's what you need to know about sustainable packaging design:

What is Sustainable Packaging Design?

Let's quickly review the essentials of sustainable packaging. According to the Sustainable Packaging Alliance, or SPA, a package that is considered "sustainable" must meet the following requirements:

  • Effective: Provides value and supports responsible decision making.
  • Efficient: Uses and maximizes green packaging materials.
  • Cyclic: Uses eco-friendly packaging materials, technologies, and inks.
  • Safe: The package poses no harm to human health or the environment.

The Role of Sustainable Package Design

Green sustainable packaging all starts with  environmentally friendly packaging design. Eco friendly packaging uses only the minimum amount of resources necessary, and always uses either renewable or recycled materials when appropriate. 

But packaging design is more than using the right materials -- it should also consider a package's environmental impact. What happens once the candy has been eaten or the shampoo has been all used up? Are the raw materials of the package easily recyclable or biodegradable? 

If you're serious about reducing packaging waste, It’s important to consider these packaging materials and options: 

  • Printing inks
  • Coatings
  • Glue / Adhesives 
  • Secondary or protective packaging

You should be evaluating every single aspect of your package design to eliminate inefficiencies.

The Role of Sustainable Packaging Inks

You can break packaging raw materials down into two groups. 

Having Eco friendly packaging practices doesn’t stop once the packaging container is structurally sound. Next comes printing, where a product really comes into its full, colorful design. 

Flexographic printing is able to print high-definition images with water-based inks, which are more eco-friendly than solvent-based ones. Flexo printers may need to adjust their equipment to adequately print with water-based inks, but the payoff is certainly worth it for those looking for a well-rounded sustainable packaging strategy. 

There are also plenty of eco-friendly coatings and adhesives to incorporate into your sustainable packaging strategy. When printing flexo, you can invest in durable image carriers that are able to serve a variety of applications including laying down adhesive in addition to traditional printing and ink transfer.

Packaging Materials Matter

We can't downplay the importance of using the right materials for your packaging. When it comes to the most sustainable packaging materials, you have a surprising number of options. 

While paper and corrugated board are perhaps the best sustainable packaging examples for their recycling benefits, new materials are being developed with similar benefits. Many people point to plastic flexible packaging as a key culprit of packaging waste. However, it's important to note that more and more modern packaging films are recyclable at store drop-off locations.

Some plastic films are even compostable or biodegradable to reduce their strain on the environment. Plastic films may not yet be a widely accepted technology, especially compared to corrugated board and paper, but advances in plastic packaging have made them less of a target for environmentalists. 

Packaging Design is Key

Ultimately, sustainable packaging design determines the life cycle of a product’s packaging. Ideally, packages should be able to support multiple uses -- reduce, reuse, recycle, right?

Consider sustainable food packaging. Above all else, it needs to keep products fresh and reduce the risk of contamination and premature spoilage. Why not design packaging that can be used multiple times? That’s why things like durable paper shopping bags are popular; unlike plastic bags, they can be used for numerous trips to the grocery store.

From a sustainability standpoint, single-use packaging doesn't maximize the resources used. Put the extra resources and design time into making a packaging that not only does its job, but also lends itself easily to reuse or recycling. 

Sustainable Printing Practices for Sustainable Packaging

Designing and executing sustainable packaging goals is a big step for companies in the fight against pollution and waste. But just as important are sustainable printing practices. 

For flexographic printing, elastomer sleeves reduce waste, cost, and setup time compared to outdated methods. Using water-based inks also lowers the emissions of volatile organic compounds.
