If you've searched for biodegradable plastic bottles for your supplement or personal care brand, you've probably run into two frustrating problems: vague green claims with no science behind them, and products that sound sustainable but fall apart under scrutiny. BioBottles® from Green Frog Packaging are different — and the difference is measurable, verified, and compliant.

## The Real Problem with Plastic Isn't What You Think

Most conversations about plastic focus on recycling. But the hard truth is that only about 9% of global plastic waste is actually recycled. The rest is landfilled, incinerated, or — critically — mismanaged, meaning it escapes into waterways, soil, and oceans. Once there, conventional plastic doesn't disappear. It fragments into persistent microplastics: particles that resist biodegradation indefinitely and accumulate throughout ecosystems.

That's the problem BioBottles® were built to solve — not by pretending plastic will disappear, but by engineering what happens when it escapes containment.

## What Makes BioBottles® Different: PlasticIQ™ Technology

BioBottles® and BioCaps™ are manufactured from standard HDPE and PP — the same materials your current filling line already handles — with approximately 1% PlasticIQ™ additive integrated at the molecular level. PlasticIQ™ is an oxo-biodegradable catalyst system that initiates controlled oxidation when packaging is exposed to environmental conditions like oxygen, heat, and UV light.

Here's what that means in practice: if a BioBottle® escapes proper disposal and enters the environment, PlasticIQ™ reduces the polymer's molecular weight from over 200,000 Daltons to below 5,000 Daltons. At that threshold, the material becomes hydrophilic and bioassimilable — meaning microorganisms can consume it, rather than leaving persistent fragments behind.

> 💡 **Note:** BioBottles® and BioCaps™ are scientifically verified under ASTM D6954 Tier 1-3 testing to prevent the formation of persistent microplastics if packaging escapes containment.

## What Is ASTM D6954 — and Why Does It Matter?

ASTM D6954 is the most rigorous testing standard for oxo-biodegradable plastics. It covers three sequential tiers: Tier 1 confirms controlled oxidation and molecular weight reduction; Tier 2 measures CO2 evolution and microbial assimilation, confirming the material becomes a food source for microorganisms; and Tier 3 validates that no harmful residues remain in the environment. PlasticIQ™ has been verified across all three tiers under the 2024 edition of this standard, with third-party validation from Jordi Labs in the United States and independent scientific experts internationally.

This isn't a marketing claim — it's a testable, documented result. And it's the foundation for the compliance-ready language your brand can actually use without greenwashing risk.

## A Drop-In Solution for Supplement and Personal Care Brands

BioBottles® and BioCaps™ are designed to work within your existing operation — no new filling equipment, no retooling, no disruption to your production schedule. They maintain full functionality and shelf life under normal use conditions, are FDA food-contact compliant under 21 CFR §§177.1520, 178.2010, and 175.300, and are recyclable through existing HDPE and PP recycling streams when properly disposed of and collected. Local recycling programs may vary.

- Drop-in replacement for standard HDPE bottles and PP caps
- FDA food-contact compliant — safe for supplements, nutraceuticals, and personal care products
- Recyclable through existing HDPE/PP recycling systems (local programs may vary)
- Verified under ASTM D6954 Tier 1-3 testing
- Third-party validated by Jordi Labs and international scientific experts
- Engineered to help reduce persistent microplastic formation if packaging escapes containment

## Why This Matters for Your Brand

Health-conscious consumers are paying attention to packaging. They're reading labels, checking claims, and choosing brands that can demonstrate — not just assert — sustainability. BioBottles® give your brand a scientifically verified story to tell: packaging that works exactly like conventional HDPE and PP under normal use, but is engineered with a responsible end-of-life pathway if it escapes containment.

Crucially, that story is compliant. Green Frog Packaging's approved claims satisfy FTC Green Guides, California SB 343, and ASTM D6954 requirements — so you can communicate your packaging choice with confidence, not legal exposure.
