In-mold Labeling and Sustainability – Friends or Foes?

by

It’s without a doubt that in-mold labeling is a growing segment among brand owners and consumers alike in both the consumer product and food segments. As a favorable alternative to glass and metals, in-mold packaging is anticipated to grow nearly 3% by 2018 – second only to shrink sleeves in packaging growth. Yet our recent attendance at the 2016 IMDA Symposium in Franklin, Tennessee sparked an interesting conversation with attendees to the Lightweight Thin Wall IML Packages session. The question that was posed was: what is the biggest threat to thin wall packaging? One of the suggested answers was…

Sustainability.

I know what you’re thinking… isn’t in-mold labeling the most sustainable option in comparison to glass and metal packaging? How can sustainability – the very reason some brands and consumers are making the switch to thin wall iml packaging – be a threat?

Sustainability as friend

When compared to its biggest rivals – glass and metals – in-mold packaging has a variety of sustainable features. Since the packaging and the label are made with the same material, the package is fully recyclable. It’s also lightweight, meaning decreased shipment emissions and a much smaller transportation footprint. In-mold packaging can also be stacked tightly, so there’s less wasted space during shipment and on store shelves (again, think shipment emissions and refrigeration/restocking costs). It’s also less likely to result in break waste and has higher safety ratings in comparison to glass and metals.

Yet many of the driving factors for thin wall packaging are less about sustainability and more about convenience, functionality, design appeal and branding longevity. While this is great for brand owners, does it resonate as equally with consumers when compared to sustainable drivers?

Sustainability as foe

While sustainability may be credited for some of in-mold packaging’s success, is may also be something that could hinder its future growth. As a demographic known for changing many consumer habits, Millennials have shown they are willing to pay more for a product with packaging that is environmentally friendly. Yet, what do they consider sustainable? Is plastic still faced with a bad rap?

One key factor in the lingering negative connotation of plastics is landfills and biodegradability. Many plastics do not biodegrade to any significant degree, while some do so very slowly if exposed to air, water and light. Nobody loves the sight of a plastic bag blowing in the wind or a plastic bottle washed up on shore – yet having them end up in a landfill is just as detrimental to the environment.

So is there a solution? In 2012, nearly 1.02 billion pounds of post-consumer rigid plastics were recycled nationwide – triple the amount recycled in 2007. Today, over 60% of people in the U.S. have access to non-bottle rigid container recycling. With trends like these headed in the right direction, the increase in rigid plastic recycling and the decrease in littering may ultimately determine the long-term success of in-mold labeling (in addition to reusability, composting and other sustainable plastic initiatives). However, it is up to both the consumer and the marketplace to continue investing in such resources. With 40% of U.S. consumers still in need of access to such recycling programs and with plastic accounting for 19.3% of the U.S. litter source, in-mold labeling will still continue to see sustainability as both friend and foe.
