In a world becoming increasingly aware of its environmental footprint, the shift toward sustainable living is no longer a mere trend—it’s a necessity.

Having worked in the packaging industry for nearly a decade, I’ve witnessed this demand change firsthand both on the brand side and consumer side. As consumers become more conscious of the consequences of plastic waste and brands seek to meet aggressive sustainability goals, both are replacing plastic. Consumers are demanding change, and businesses are taking notice.

This transformation is not just about reducing waste, but also about a fundamental shift in how businesses approach packaging. Sustainability in packaging is evolving beyond aesthetics, and also involves the materials and functional elements of the packaging solutions. The shift towards packaging materials that can be recycled seems to be driven by a genuine desire to make a positive impact.

The move to sustainable packaging goes beyond materials, encompassing the entire product lifecycle. This shift, adopting a cradle-to-cradle approach, entails changes in design, production, distribution, and disposal. But it presents challenges, too, demanding R&D investments, manufacturing alterations, and supply chain adjustments. Yet, the advantages surpass the challenges. Brands embracing sustainable packaging align with consumer values and future-proof their businesses, while those not adapting risk falling behind as regulations and consumer expectations evolve.

1. CIRCULARITY

At the heart of this evolution is the importance of recyclability and circularity. As businesses strive to reduce their environmental impact, switching from plastic to alternative materials is not enough. One prominent measure of sustainable packaging is its ability to be recycled and reintegrated into the production cycle, creating a loop that minimizes waste and conserves resources.

Explore the benefits of using multiple circular materials to form a more sustainable packaging offering that reduces carbon footprint while maintaining functionality and appeal for the consumer.

One example of this is in the luxury perfume sector, where pioneer brands use aluminum bottles for perfume refills, reducing the need for consumers to repurchase their heavier decorative glass packaging when the product has been used up. The lighter-weight refill bottle reduces energy in production, transportation, and recycling, but still offers circularity in its packaging.

2. SUSTAINABLE MATERIALS AND THEIR BENEFITS

When comparing different packaging materials, metal stands out for its circularity, preservation of nutritional values with a complete barrier construction, and market value. Other materials, such as glass or plastics, have different environmental credentials.

Glass, for example, can be used to see the content and, if sorted correctly, is recyclable. Plastics are lightweight, but do not form a complete barrier and are globally recycled at a lower rate than metals. Paper-based packaging materials often need extra plastic layers to protect the paper from moisture during transportation. These layers make these packages hard to recycle, and most of the time, only a portion of the material in the pack can be reused for new applications.

Just like in the perfume industry, the use of aluminum bottles is gaining momentum. Aluminum bottles are recyclable and offer a range of practical advantages. Aluminum is lightweight, infinitely recyclable, and corrosion-resistant. It does not rust and can be shaped in different sizes with extraordinary print and finish design opportunities to let brands shine on the shelf. When aluminum is recycled, only a fraction of the energy is needed compared to the first use.

With 80% of all metal ever produced still in the loop today, these packaging solutions provide a great source of available resources for future generations.

3. TRANSITIONING YOUR PRODUCTION AND SUPPLY CHAIN

The versatility and scalability of aluminum bottle production empower manufacturers to seamlessly transition between small-scale and large-scale manufacturing, catering to the needs of brands introducing new products or making the switch from glass or plastic containers to aluminum.

While the shift to aluminum bottles can be smooth for glass production lines, plastic bottling lines may require a careful assessment and possible modifications to ensure efficient and effective production. This adaptability positions aluminum bottle production as a flexible choice for brands looking to diversify materials or broaden their product range.

Exploring an alternative approach involves outsourcing the filling process to third-party fillers and packers equipped to handle aluminum bottle filling. This option proves advantageous for brands testing new products or aiming to expedite the introduction of new packaging to the market.

Consideration of supply chain implications is also crucial, particularly concerning costs related to leakage and damage from existing packaging materials. Aluminum bottles, due to their robustness, can significantly reduce or eliminate leakage and associated damages, as their strength enables them to withstand impacts that might otherwise compromise or break other packaging materials.

4. CUSTOM PACKAGE DESIGN AND BRANDING

Aluminum stands out as a packaging material due to its remarkable capacity to be molded into myriad shapes. I’ve frequently collaborated with industry leaders who find themselves pleasantly surprised by the level of influence they wield over the packaging format. This influence spans from conventional dimensions in terms of height and diameter to crafting beverage bottles featuring unique neck designs or personal care product bottles with smooth contours that evoke sophistication or improve ergonomic usability.

The versatility of aluminum also encompasses various closure choices, such as metal threaded closures, which hold particular appeal for wine and spirits manufacturers seeking protection against UV and light exposure. Additionally, aluminum exhibits compatibility with existing pumps, foamers, and misters, further enhancing its adaptability in packaging solutions.

Direct printing eliminates the need for additional materials, such as labels. As consumers become more discerning and conscious of their choices, this sustainable aesthetic appeal can be a powerful point of sale differentiator.

The transformation of packaging towards sustainability is a testament to the power of consumer demand and the innovation capabilities of businesses.

As we move towards a future where sustainability is the norm, it’s clear that sustainable packaging looks a little different—and that’s a good thing. It represents progress, innovation, and a commitment to a healthier planet for future generations. It’s a change we can all embrace, one bottle or package at a time.
