Sustainable Packaging for Shopify Stores: A Practical Guide
Sustainable packaging for a Shopify store comes down to three decisions: use less material (the right box size for each order), choose materials your customers can recycle or compost where they live, and describe what you did precisely instead of calling it “eco-friendly”. Shopify helps with the first through package presets and packed product sizes, which pick the smallest saved box that fits, and with shipping emissions through its Planet app. The materials are your call, and so is the wording.
Shopify settings and Planet details come from its pages on packages and Planet (read October 23, 2026). The materials comparison is our summary of common options, not a lifecycle study; check claims with your supplier’s certificates.
Materials compared
| Material | Good for | Cost compared to standard | End of life for the customer | Watch out for |
|---|---|---|---|---|
| Recycled corrugated cardboard box | Most products, fragile items | Similar | Paper recycling, where collected | Oversized boxes waste the benefit |
| Kraft paper mailer bag | Clothing, soft goods, flat items | Similar or a little higher | Paper recycling | Tears when wet; not for sharp corners |
| Paper fill (crinkle, honeycomb wrap) | Replacing plastic air pillows and bubble wrap | Higher per order, takes more space to store | Paper recycling | Needs more volume to protect heavy items |
| Compostable mailer (plant-based film) | Replacing plastic poly mailers | Higher | Compost, but often only in industrial facilities | Customers may put it in plastic recycling, where it does not belong |
| Recycled-content plastic mailer | Clothing, waterproof shipping | Similar | Plastic film recycling where collected | Still plastic; say “recycled content”, not “eco” |
| Molded pulp insert | Holding bottles, electronics, glass | Higher, needs a minimum order | Paper recycling or compost | Must match the product exactly |
| Reusable mailer | Repeat customers, apparel | Much higher per unit, lower per use if returned | Returned and reused | Only works if customers send it back |
| Paper tape | Sealing boxes | Similar | Recycled with the box | Water-activated tape needs a dispenser |
Two rules make the table useful. First, the material that matters most is the one that touches the customer’s bin, so pick materials their local collection accepts; a “compostable” mailer that ends in landfill does less than a recyclable paper one. Second, mixed materials (plastic windows on paper, foil-lined bags) are harder to recycle than either material alone.
If your products are fragile, test-ship them in the new materials before switching. A broken product shipped twice uses more packaging and transport than a slightly heavier first box.
Right-size every box
Empty space in a box is the easiest waste to cut, and Shopify can help you avoid it:
- Save your real boxes under Settings > Shipping and delivery > Packages > Add package, with outside dimensions and weight. Carriers price by outside dimensions.
- Add a packed product size to each product (length, width and height after packing; all three or none). When every item in a shipment has one, Shopify packs the items into the smallest saved box that fits, and the customer pays a rate closer to what the label costs. Only packages of the Box type are used this way.
- Assign a package to a product for single-item orders (Package when shipped alone in the product’s Shipping section).
Shopify falls back to your store default package when an item has no packed size, when no saved box fits, or when an order has many items, so fill in packed sizes for your best sellers first. Our guide to package sizes in Shopify explains these settings in detail.
Fewer box sizes are not automatically greener. Three or four sizes matched to your product range need less fill than one box for everything, while fifty sizes make packing slow and Shopify falls back to the default package when you save a large number of boxes.
Reusable mailers
Reusable mailers are sturdy bags or boxes that the customer returns, often folded into a letterbox, so the next order can use them. They make the most sense for apparel stores with repeat customers and for subscriptions, where the same customers receive parcels regularly.
Before you offer them, check three things with the provider: how the customer sends the mailer back and who pays that postage, how many trips a mailer is expected to make, and what happens to mailers that are never returned. Ask for those figures in writing; the environmental case depends on the mailer actually coming back.
Carbon-neutral shipping with Planet
Packaging is one part of a parcel’s footprint; transport is another. Shopify’s Planet app funds companies that remove carbon dioxide from the atmosphere and store it, to offset your shipping emissions. It has two subscription options: you pay to make all shipments carbon neutral, or customers choose to pay $0.50 USD at checkout for carbon-neutral shipping. Planet adds a badge for your store and analytics showing carbon-neutral shipments and the carbon removed. Our article on carbon-neutral shipping covers the setup and the emissions calculation.
Say it honestly
Advertising rules in many countries (the US Federal Trade Commission’s Green Guides, for example) expect environmental claims to be specific and provable. Practical wording rules:
- Name the material and the share. “Box made from 100% recycled cardboard” instead of “eco packaging”.
- Say how to dispose of it. “Recycle the box and paper fill with your paper waste; the mailer is industrially compostable, not home compostable” tells the customer what to do.
- Do not claim what you cannot prove. “Plastic-free” means no plastic tape, labels or windows either.
- Keep offsets separate from packaging. Planet makes shipping carbon neutral through carbon removal; it does not make the box sustainable.
- Put it where customers see it: a line on product pages, a printed note in the box, and a short section in your shipping policy.
For the rest of the box (inserts, tissue and the packing slip), see unboxing experience; for a tight budget, packaging on a budget. More shipping topics live in the shipping and returns hub.
FAQ
What is the most sustainable packaging for a Shopify store? The best choice is usually the smallest box that protects the product, made of a material your customers’ local collection accepts, such as recycled cardboard with paper fill. Right-sizing is the change every store can make, whatever material it uses.
Can Shopify choose the right box size automatically? When every product in a shipment has a packed product size, Shopify packs the items into the smallest of your saved boxes that fits them. Otherwise it uses your store default package.
Does Shopify offer carbon-neutral shipping? Shopify’s Planet app makes shipments carbon neutral by funding carbon removal. You can pay for all shipments or let customers opt in for $0.50 USD at checkout.
Are compostable mailers better than plastic ones? They are better only if they reach a composting facility that accepts them, which often means an industrial one. Tell customers exactly how to dispose of the mailer, or a recyclable paper mailer may be the safer choice.
