The protective materials inside your shipping boxes are a small detail with an outsized environmental footprint. Bubble wrap has been the default for decades — familiar, effective, and cheap. But as consumer expectations shift and packaging regulations tighten, more e-commerce brands are asking whether paper void fill is the smarter choice. The short answer is: often yes, but the full picture is more nuanced than swapping one material for another.
This guide breaks down paper void fill versus bubble wrap across the dimensions that matter most to online sellers: what each material actually does, how recyclable each really is, when one outperforms the other, and the mistakes brands make when switching. Whether you’re a sustainable-first startup or an established operation looking to reduce plastic, here’s what you need to know.
Quick Answer
For the majority of e-commerce shipments, paper void fill is the more sustainable option — it’s curbside recyclable, biodegradable, and effective for most standard product categories. Bubble wrap, made from low-density polyethylene (LDPE) plastic, requires store drop-off recycling that most customers never use, and persists in landfill for decades. That said, bubble wrap’s shock absorption still has an edge for individually wrapping very fragile or high-value items. For most brands, the best approach is to eliminate plastic bubble wrap from void fill entirely and reserve it — or a paper equivalent like honeycomb paper wrap — only for direct item wrapping where impact protection is critical.
What Each Material Actually Does
Paper void fill and bubble wrap are often treated as interchangeable, but they serve different primary functions. Paper void fill — typically crumpled or mechanically crinkled kraft paper — is designed to fill empty space inside a box, preventing contents from shifting during transit. When packed firmly, it also provides real cushioning. Bubble wrap, by contrast, excels at wrapping individual items to absorb impact — its air-filled cells compress under stress, dispersing the kinetic energy of a drop before it reaches the product’s surface.
This distinction shapes when each material makes sense. If your goal is to stop a product from rattling around inside a well-sized box, paper void fill does that job well. If you need a protective layer directly around a fragile item that might take a hard impact — bare glassware, delicate ceramics, exposed electronics — bubble wrap’s surface cushioning is harder to match without the right paper alternative. Many sellers use a hybrid: a paper or honeycomb wrap layer directly around the item, then crumpled paper to fill remaining space. This can be entirely plastic-free while maintaining strong protection.
Sustainability Side-by-Side
The environmental gap between paper and bubble wrap is real and significant. Bubble wrap is made from LDPE (low-density polyethylene, plastic #4), a fossil-fuel-derived film that is not accepted in curbside recycling. Customers must take it to a store drop-off location — major retailers like grocery chains and home improvement stores often have plastic film collection bins — to recycle it properly. In practice, most bubble wrap ends up in the general waste bin. In landfill, it can take decades or centuries to break down, and it eventually fragments into microplastics that enter soil, waterways, and food chains.
Paper void fill, by contrast, goes in the standard recycling bin in most areas and is also biodegradable and compostable. It’s typically made from recycled content, keeping materials in circulation rather than extracting new resources. For customers who already separate their recycling, disposing of paper packaging requires zero extra effort — a meaningful difference from asking them to find a plastic film drop-off point. From a brand perception standpoint, paper packaging also signals environmental responsibility in a way that resonates with a growing share of online shoppers.
Regulatory trends are accelerating this shift. The EU Packaging and Packaging Waste Regulation (PPWR) — Regulation 2025/40 — is a landmark framework that brands selling into EU markets need to understand. While the regulation’s general provisions begin applying from August 12, 2026, its empty space requirement for e-commerce packaging operates on a later timeline: under Article 24, economic operators must ensure e-commerce packaging has a maximum empty space ratio of 50% by January 1, 2030, or three years after the Commission publishes implementing acts establishing the measurement methodology (whichever is later). The Commission is required to adopt that methodology by February 12, 2028. Filler materials — including paper, bubble wrap, and air pillows — all count as empty space under this calculation, so the regulation incentivizes right-sizing boxes and minimizing fill overall, not just switching from plastic to paper. Businesses shipping into EU markets should begin auditing their packaging efficiency now, well ahead of the 2030 deadline.
Which to Use and When
Choose paper void fill as your default for most shipments. It’s the right call for clothing, books, home goods, cosmetics, non-fragile food products, and small electronics shipped in their original retail packaging. Paper dispensers and hand-crumpling systems also take up far less warehouse space than bulky rolls of pre-inflated bubble wrap, which can free up meaningful square footage in a fulfillment operation. If you’re using a machine dispenser, systems from companies like Ranpak produce consistent crinkle paper fills that speed up packing lines.
Keep bubble wrap — or switch to a plastic-free equivalent — for items that genuinely need surface-level impact protection: bare glassware, decorative ceramics, framed artwork, sensitive electronics without original packaging, or high-value items where a damage claim would be costly. Honeycomb paper wrap is the most direct plastic-free substitute: it wraps around products like bubble wrap, provides comparable cushioning for most fragile categories, and is fully recyclable curbside. Molded paper pulp inserts are another option for standardized fragile products where upfront tooling investment is worthwhile.
A practical decision rule: if the item would survive a one-foot drop without packaging, paper void fill alone is sufficient. If it wouldn’t, consider what’s failing — is it the lack of surface protection, or the lack of in-box stability? If it’s stability, pack paper fill more firmly. If it’s surface protection, that’s where honeycomb wrap or a paper cushioning wrap earns its keep.
Tips and Common Mistakes
Don’t over-fill with loose bubble wrap assuming more is better. An oversized box stuffed loosely with bubble wrap can still allow items to bounce — particularly if bubbles compress or pop. Properly crumpled kraft paper packed tightly around and underneath an item prevents movement as reliably as loosely applied bubble wrap, and holds its structure better through the full transit.
Don’t tell customers bubble wrap is recyclable in the recycling bin. It isn’t — not curbside. Including recycling instructions on your packing slip is a great sustainability touch, but inaccurate instructions for bubble wrap (or any plastic film) send material to landfill and damage trust. If you’re switching to paper, the instruction is simply ‘recyclable curbside’ — straightforward and accurate.
Don’t neglect box sizing. Switching void fill from plastic to paper while continuing to ship in oversized boxes trades one waste problem for another. The most impactful move is to right-size your packaging first, then use the minimum fill needed to secure contents. This also positions you for compliance with the EU PPWR Article 24 empty space requirements, which take effect from January 1, 2030 (or later, depending on when the Commission publishes its measurement methodology) for e-commerce packaging.
Do run drop tests before committing to a new fill solution. Crumple paper by hand, pack your product, and drop the box onto a hard surface from shipping height. This five-minute test often reveals whether your paper fill approach is adequate — or whether you need to adjust packing technique, add a wrap layer, or right-size the box — before you commit to a full switch.

paper void fill vs bubble wrap FAQs
Is bubble wrap recyclable in the curbside bin?
No. Bubble wrap is made from LDPE plastic film, which tangles in the machinery at standard recycling facilities and is not accepted curbside in most municipalities. It can be recycled through store drop-off programs at retailers that collect plastic film — grocery chains and home improvement stores often have collection bins. The site plasticfilmrecycling.org can help you find a location. In practice, most bubble wrap that doesn’t reach a drop-off point ends up in landfill.
Is paper void fill as protective as bubble wrap?
For its primary function — filling empty space in a box to prevent shifting — paper void fill performs comparably to bubble wrap and often better when packed firmly. For directly wrapping fragile items that need shock absorption on impact, bubble wrap has a traditional edge, though honeycomb paper wrap is a plastic-free alternative that performs well for most fragile categories. The key is matching the right material to the right job: paper for void fill, a wrap layer (paper or otherwise) for surface protection on delicate items.
What is the EU PPWR regulation and how does it affect packaging choices?
The EU Packaging and Packaging Waste Regulation (PPWR), officially Regulation 2025/40, is a broad framework that applies to businesses placing packaged products on EU markets. Its general provisions begin applying from August 12, 2026. However, the specific Article 24 requirement limiting empty space in e-commerce packaging to a maximum of 50% does not take effect until January 1, 2030 — or three years after the European Commission adopts implementing acts establishing the measurement methodology (whichever is later). The Commission must adopt that methodology by February 12, 2028. Importantly, filler materials such as paper fill, bubble wrap, and air pillows all count as empty space under this calculation, so brands should focus on right-sizing boxes and minimizing total fill — not just substituting plastic for paper.
