Foam inserts and plastic air pillows protect products, but they also cheapen the moment a customer opens the box — and they’re one of the first things shoppers flag as wasteful. The good news is that paper-based and fiber-based inserts have gotten good enough to replace plastic in most cases, without giving up the snug fit or polished look that makes an unboxing feel premium.
This guide walks through the main plastic-free insert options, how to pick one for your product, and how to avoid the common mistakes that make paper inserts feel flimsy instead of upscale.
Quick Answer
Replace foam and plastic air pillows with molded fiber trays (for a tailored, high-end fit), honeycomb kraft paper wrap (for cushioning fragile items), or die-cut corrugated inserts and dividers (for structure and compartments). Pair whichever base you choose with branded tissue paper or a printed kraft wrap to carry the premium feel through.
The Main Plastic-Free Insert Options
Molded fiber (also called molded pulp) is pressed from recycled paper fibers and water into a custom mold, similar to how egg cartons are made but refined with smoother finishes for retail use. It can be shaped to cradle an exact product — a bottle, a device, a set of components — and comes in smooth or textured finishes. It’s recyclable and often compostable, and it reads as premium because it looks intentional rather than generic. The tradeoff is tooling: a custom mold is an upfront cost, so it makes the most sense once you’re ordering inserts by the thousands for a signature product.
Honeycomb paper wrap (sold under names like GreenWrap) ships flat and expands into a cushioned, accordion-like layer of kraft paper, functioning as a plastic-free stand-in for bubble wrap. It’s a good fit for wrapping irregular or fragile items and for filling empty space in a box without the hollow rattle of crumpled paper alone.
Die-cut corrugated inserts — trays, dividers, and sleeves cut from cardboard — give you structure: separate compartments for multiple SKUs, a slot that holds a product at a fixed angle, or a riser that lifts the product up so it’s the first thing seen on opening. These are the cheapest option to prototype since they can be cut on a standard die or even a hand cutter before you commit to a supplier run.
Crinkle paper, shredded kraft, and tissue paper remain the simplest void-fill and finishing layers. They don’t do much structurally, but a colored or printed tissue layer on top of a sturdier insert is often what actually makes the unboxing feel curated — it’s the first thing the customer sees and touches.
How to Choose and Implement One
Start by defining what the insert actually has to do: hold a fragile item still during transit, fill dead space so nothing shifts, or create a reveal moment. Fragile or heavy items usually need molded fiber or a corrugated tray with a snug cut; light or oddly-shaped items do fine with honeycomb wrap or crinkle paper.
Prototype cheap before you tool up. Cut a corrugated insert by hand or order a small sample run of molded fiber trays before committing to a full production order — a mold change after the fact is far more expensive than a design iteration on paper.
Test the insert the way the box will actually be handled: drop-test a sealed package from table height, ship a few test units, and check that the product doesn’t shift or that corners aren’t crushing the insert. Paper-based materials protect well against the kinds of impacts most packages actually see, but they compress differently than foam, so don’t assume a foam-tested design will automatically translate.
Source FSC-certified or recycled-content paper and kraft where possible, and confirm with your supplier whether the finished insert is recyclable, repulpable, or compostable in standard municipal systems — claims here vary by ink, coating, and adhesive used, so check rather than assume.
Tips / Common Mistakes
Don’t under-engineer the fit. A loose insert that lets the product shake around undermines the premium feel faster than any material choice — a snug, deliberate cut matters more than which paper you picked.
Go easy on plastic tape, laminated coatings, and plastic-backed ribbon on an otherwise plastic-free package. Ordinary plastic tape is usually separated out early in a paper mill’s repulping process, so a small amount of it on a box won’t ruin recyclability — but heavy taping, plastic laminates, or plastic-coated ribbon add up and make sorting and repulping harder, so it’s worth switching to paper tape or minimizing tape use where you can.
Don’t skip the drop test. Molded fiber and corrugated inserts protect differently than foam, and a design that looks right on a shelf can still fail in transit if the cushioning depth is too thin for the product’s weight.
Keep branding on the insert simple — a single stamped logo or one ink color on kraft paper reads as premium; heavy full-color printing on paper inserts can look cheap and also makes the material harder to recycle.

Plastic-free unboxing inserts FAQs
Are paper-based inserts as protective as foam?
For most consumer products, yes — molded fiber and well-designed corrugated inserts can match foam’s protection, but they compress and flex differently, so you should drop-test your specific product rather than assume a foam-based design will transfer directly.
What’s the cheapest way to prototype a plastic-free insert?
Die-cut corrugated cardboard is the easiest to prototype — you can cut a tray or divider by hand or with a basic cutter before paying for tooling, then move to molded fiber once the design is locked and volume justifies a mold.
Can plastic-free inserts still look premium for a luxury brand?
Yes — molded fiber in particular is used by luxury and tech brands because its smooth or textured finish and custom-fit shape look deliberate, and pairing it with a branded tissue layer or single-color print adds a finished look without plastic.
