The Seal That Doesn't Outlive Its Shipment
Mega Fortris has built a biodegradable bio-additive into every plastic security seal we make – without giving up a single millimetre of tamper-evidence.
Every security seal we have ever made is still out there somewhere. That’s the job – a seal has to survive tampering, weather, transit, an years in a supply chain most people never see. But durability has a cost after the job is done. Once a seal is cut and discarded, the same plastic that made it tamper-proof makes it near-permanent as waste.
For an industry built on single-use plastic components, that’s becoming harder to justify – to auditors, to customers, and to the sustainability targets showing up on more procurement scorecards every year. We didn’t think the answer was a weaker seal. So we built a smarter one.
A bio-additive, not a compromise
Since May 2024, every Mega Fortris security seal with plastic content (our full range of polypropylene and nylon seals) has included the BioSphere bio-additive as standard.
It isn’t a coating, and it isn’t recycled content pretending to solve the whole problem, though our seals include that too: 30% recycled content across our polypropylene range. BioSphere is mixed directly into the base polymer. Once a seal reaches landfill or a similar anaerobic environment, the additive activates naturally occurring microbes, which break down the plastic’s polymer bonds from the inside out.
What’s left afterwards isn’t microplastic. It’s low-weight, non-toxic compound and water – byproducts that are compatible with recycling processes rather than working against them.
Certified, not just claimed
‘Biodegradable’ gets used loosely in this industry, so we didn’t stop at bio-additive. Seals made with BioSphere technology are certified to ISO 14021:2016, the international standard defining what ‘biodegradable’ is allowed to mean on a product label – and they’re independently tested against four further methods.
Still the seal you already trust
None of this changes what a Mega Fortris seal is built to do BioSphere enabled seals carry the same tamper-evidence, the same ISO 17712 compliance, and the same physical performance as every seal we’ve shipped before. The bio-additive changes what happens after the seal’s job is done – not how well it does that job.
What stays the same
- Tamper-evidence and security performance
- ISO 17712 compliance
- Application method and fit
- Lead times and product range
What changes
- What happens to the seal after disposal
- Its footprint in landfill or anaerobic conditions
- Your answer to sustainability audits
For procurement and security teams, that means no re-qualification headache and no trade-off to defend internally. It’s a drop-in upgrade to a product line you already specify.
One less line item to justify
Security seals rarely show up in sustainability conversations – they’re small, functional, and easy to overlook next to packaging or freight emissions. But as ESG reporting extends further into Scope 3 and supplier scorecards, every plastic component in a supply chain eventually gets a question mark next to it.
BioSphere gives supply chain, procurement, and sustainability teams a straightforward answer for one of those line items – backed by test data, not a green logo. It won’t solve a company’s entire footprint. But it removes one component that used to have no good answer at all.
