Sustainable Packaging Solutions: Finding the Right Balance
More sustainable packaging solutions can help brands reduce plastic waste, meet changing consumer expectations, and, when implemented correctly, potentially lower fulfillment and shipping costs. The key is looking beyond the packaging material itself. Right-sizing packages, reducing unnecessary materials, and designing a smarter overall pack-out can sometimes have a greater impact than simply replacing one material with another.
For e-commerce and DTC brands, the goal should be practical: use the least amount of packaging necessary to protect the product, deliver a positive customer experience, and get the order to its destination cost-effectively.

What Types of Sustainable Packaging Materials Are Available?
There is no single sustainable packaging solution that works for every product. An apparel brand shipping lightweight clothing has very different requirements from a beauty company shipping liquids or a housewares brand shipping breakable products.
Companies should research and evaluate packaging materials based on several factors: product protection, recyclable content, material usage, weight, package dimensions, cost, and the customer's ability to properly dispose of the packaging.
Here are some of the most practical sustainable packaging options.
Recycled and Recyclable Cardboard & Kraft Paper
Corrugated cardboard remains one of the most versatile packaging materials for e-commerce. Boxes can incorporate post-consumer recycled (PCR) content, and corrugated packaging is recyclable and widely accepted through recycling programs.
Recycled paper packaging and kraft paper can also replace plastics such as bubble wrap or foam peanuts for many applications. Crumpled or converted kraft paper can provide cushioning and prevent products from moving inside the carton.
These materials can be particularly effective for:
- Apparel and footwear
- Housewares and home goods
- Subscription boxes
- Consumer products
- Multi-item e-commerce orders
However, simply switching to recycled corrugated does not necessarily make a packaging program efficient. A product shipped in a box twice the necessary size still consumes excess corrugated, requires more void fill, and may create unnecessary transportation expenses.
That's why package size matters just as much as package material.
Biodegradable and Compostable Materials
Innovations in biodegradable and compostable packaging have expanded significantly, giving companies alternatives to conventional plastic packaging.
Depending on the application, options can include plant-based packing peanuts, food-safe molded pulp inserts, compostable bags, mushroom-based protective packaging, and reusable or compostable flexible packaging or mailers.
These materials may be appropriate for brands in categories such as:
- Food and beverage
- Health and beauty
- Supplements
- Personal care
- Environmentally focused consumer products
Brands should pay close attention to manufacturing certifications, food-contact compliance, and disposal requirements. "Compostable," for example, does not necessarily mean that a package will readily decompose in a customer's backyard compost pile. Some compostable packaging requires commercial or industrial composting facilities.
Clear disposal instructions on the packaging can help ensure that an environmentally preferable material actually reaches the appropriate waste stream and re-enters the circular economy.
Recycled Plastics and Flexible Film
Eliminating plastics entirely isn't always practical.
Apparel, soft goods, and other products may benefit from the lightweight and moisture resistance of flexible packaging. In these situations, packaging containing high-quality recycled materials can provide a middle ground between functionality and reducing plastic waste.
Options can include poly bags and mailers manufactured with recycled content, including recycled polyethylene terephthalate (rPET), as well as certain flexible films designed for applicable store drop-off recycling streams.
Because flexible packaging is lightweight, it can also require substantially less material than a corrugated box for appropriate products.
The most sustainable packaging solution is therefore not necessarily the one containing the least plastic. Brands should consider the entire packaging and transportation lifecycle when selecting materials.
Right-Sized and Custom Packaging
One of the biggest sustainable packaging innovations isn't a new material at all.
It's eliminating packaging you never needed in the first place.
Oversized boxes create several problems. They consume more corrugated material, require additional void fill, occupy more space in trucks, and can increase parcel shipping costs due to dimensional weight pricing.
Right-sized packaging attacks all of those problems simultaneously.
Instead of selecting a carton that is simply "close enough," innovative cartonization technology can determine the appropriate package based on the products in each individual order.
A more appropriately sized package can mean:
Less corrugated + less void fill + less transportation volume + potentially lower shipping costs.
It can also create a cleaner unboxing experience. Customers receive a package that feels intentionally designed for what they purchased instead of opening a large box containing a small item surrounded by packing material.
How Much Do Sustainable Packaging Solutions Cost?
One of the first questions brands ask is straightforward:
Is sustainable packaging more expensive?
Sometimes.
Recycled, certified compostable, and specialized eco-friendly packaging can carry a higher per-unit production cost than conventional alternatives. Custom-branded eco-friendly packaging may add additional expense as well.
But comparing packaging based only on the price of a box or mailer can produce the wrong conclusion.
Brands should evaluate the total delivered cost of the package.
Where Brands Often See Savings
Lower Dimensional Weight
Parcel carriers can calculate shipping charges based on dimensional weight rather than actual weight. That means shipping a lightweight product in an unnecessarily large box can increase transportation costs.
Reducing package dimensions enables more efficient shipping and can therefore produce savings that outweigh a modest increase in packaging material cost.
Less Packaging Material
Right-sized cartons require less corrugated material and typically less void fill. Reducing raw materials consumption is one of the rare sustainability initiatives that can simultaneously reduce environmental impact, carbon footprint, and operating expenses.
Reduced Damage and Returns
Quality eco-friendly packaging still has to perform its most important job: protecting the product.
Reducing packaging without considering protection can be a costly mistake. Damaged products create replacement shipments, returns, additional transportation, and dissatisfied customers, all while generating more waste and enlarging your environmental footprint.
The objective isn't minimum packaging. It is optimal packaging.
Potential Brand and Customer Value
Packaging is one of the few physical interactions an e-commerce customer has with a brand.
An efficient, eco-friendly package can reinforce a company's sustainability positioning without compromising the customer experience. For brands seeing consumer demand for sustainability, that experience can contribute to loyalty, repeat purchases, and long-term business growth.
Cost Factors to Consider
The economics of sustainable packaging for your business will depend on:
- Shipment and order volume
- Packaging material
- Package dimensions
- Custom versus stock packaging
- Printing and branding requirements
- Material certifications and compliance
- Product protection requirements
- Minimum production order quantities
- Freight required to transport packaging to the fulfillment center
- Storage space consumed by packaging inventory
Higher-volume businesses may have greater opportunities to negotiate market pricing and amortize custom packaging costs across more orders.
Working with a 3PL can also give companies access to established packaging suppliers, resources, purchasing scale, and packaging innovations that would be difficult for an individual brand to justify independently.
How Does Sustainable Packaging Benefit Your Brand?
Reducing waste is an important objective for the planet, but sustainable packaging can also provide broader business benefits.
A Better Customer Experience
Customers are aware of packaging.
An oversized box filled with unnecessary plastic packaging and void fill can create an immediate disconnect for a brand that otherwise promotes sustainability.
Conversely, a compact, well-designed package can communicate efficiency and intentionality before the customer even touches the product.
For beauty, supplements, pet products, apparel, and other competitive DTC businesses, packaging can become an extension of the brand itself.
Alignment With Retailer and Marketplace Requirements
Retailers, marketplaces, and companies across e-commerce continue to focus on packaging efficiency, ways to improve recyclability, and waste reduction.
Amazon, for example, operates its Ships in Product Packaging (SIPP) program, which allows qualifying products to ship in their own packaging without additional Amazon packaging. Eligible products can also receive fulfillment fee discounts.
Designing packaging to comply with marketplace requirements can therefore create opportunities to reduce both packaging materials and fulfillment costs.
Less Waste Throughout the Fulfillment Process
Sustainable practices shouldn't begin when the warehouse associate reaches the packing station.
Brands can adopt more sustainable practices throughout the supply chain, including how products arrive from production partners, how inner packs are configured, how shipping supplies are stored, and how products are prepared for outbound shipping.
Removing or reusing unnecessary packaging at multiple points can compound the savings and your sustainability progress.
Competitive Differentiation
Consumers increasingly encounter similar products from different companies at similar prices across the e-commerce market and social channels.
Packaging provides brands with another way to differentiate.
Eco-friendly packaging doesn't have to mean plain brown boxes and a compromised brand experience. Reusable mailers, recycled packaging, custom printing with soy or algae ink, branded kraft paper packaging, inserts, and other materials can create an attractive unboxing experience while supporting broader sustainability goals for your brand and the planet.
The strongest programs combine the two.
Sustainability and presentation don't have to be competing priorities.

Reducing the physical size of shipments doesn't just eliminate packaging waste and shrink your carbon footprint. Smaller packages can also reduce shipping costs, creating a benefit for the environment and the bottom line from the same operational improvement.
Custom Sustainable Pack-Outs
Different companies have different sustainability goals and levels of commitment.
For brands committed to eco-friendly materials, a2b can support custom pack-out requirements incorporating selected packaging materials, branded elements, inserts, tissue, void fill, and other specifications.
Our Divert-to-Finishing automation helps ensure that orders requiring specialized handling or custom pack-outs are automatically routed to the appropriate finishing process rather than relying solely on manual identification.
That allows your sustainability commitment to become part of a repeatable fulfillment workflow.
Kitting & Assembly
Changing packaging formats can also create operational challenges, particularly when existing products need to be repackaged, assembled into kits, or transitioned to a new configuration.
a2b's kitting and assembly capabilities allow brands to implement new processes and packaging strategies without unnecessarily disrupting their core order fulfillment operation.
That flexibility can be especially valuable when brands are testing new products and materials, introducing retail-ready packaging, or future-proofing with a new sustainable packaging format.
Sustainable Packaging Should Be Sustainable for Your Business, Too
The best sustainable packaging solutions don't simply replace one material with another. They consider materials, package dimensions, product protection, shipping expenses, customer experience, and operational efficiency together.
By reducing unnecessary packaging and designing smarter pack-outs, businesses can often improve sustainability and contribute to a healthier planet and a more sustainable future while simultaneously reducing fulfillment and transportation costs. a2b Fulfillment combines packaging expertise, resources, cartonization, right-sized packaging solutions, and custom fulfillment workflows to help brands find that balance.

Sustainable Packaging FAQs
Is sustainable packaging more expensive than traditional packaging?
Some eco-friendly materials carry a higher per-unit cost than conventional alternatives, but packaging price alone doesn't tell the whole story. Right-sized packaging can reduce corrugated usage, void fill, and dimensional weight, potentially creating shipping and material savings that offset some or all of the additional packaging expense.
Can my 3PL accommodate custom sustainable packaging specifications?
Yes, provided the 3PL has the processes and technology to support custom pack-outs. Brands may specify recycled or recyclable materials, branded inserts, tissue, void fill, and other packaging requirements. a2b Fulfillment can incorporate custom packaging requirements into defined fulfillment workflows.
Do consumers actually care about sustainable packaging?
Consumer demand for sustainability can influence customer perception and purchasing decisions, particularly for consumers who care about the environment. More importantly, packaging is a highly visible part of the e-commerce customer experience. Excessive or difficult-to-dispose-of packaging can conflict with a brand's sustainability message, while thoughtfully designed packaging can reinforce it.
What is the most sustainable packaging material?
There isn't one answer for every product. Recycled corrugated, kraft paper, recycled-content flexible packaging, molded fiber, and biodegradable and compostable packaging can all make sense depending on the application, including food and beverage requirements. Companies should evaluate material consumption, recyclable content, product protection, package weight and dimensions, and available disposal infrastructure rather than choosing a material based on a single sustainability claim.
How can right-sized packaging reduce shipping costs?
Parcel carriers frequently use dimensional weight when determining shipping charges. An unnecessarily large box can therefore cost more to ship even when the product itself is lightweight. Right-sized packaging reduces empty space and package dimensions, which can lower dimensional weight while also reducing corrugated and void fill usage.
