What Are The Specifications Of The Plastic Used In Flow Frames? High-Quality, Food-Grade & Bpa-Free Material

Flow Frames are engineered from high-quality, food-grade plastic that is strictly certified as BPA-free. This material contains no bisphenol compounds and has been verified by third-party laboratories to be free of estrogenic and androgenic activity, ensuring it is chemically inert within the hive environment.

Core Takeaway: While the plastic frames meet rigorous safety standards, the purity of your honey is ultimately preserved by the bees themselves. Before storing nectar, bees naturally coat the plastic cells with their own wax, creating a biological barrier that prevents the honey from ever coming into direct contact with the frame structure.

Chemical Composition and Safety Standards

Bisphenol-Free Assurance

The primary specification for these frames is their safety profile regarding bisphenols. The plastic is not only BPA-free but also free from other bisphenol compounds often found in lower-grade plastics.

Hormonal Activity Testing

To ensure the material does not disrupt biological systems, it undergoes rigorous testing. Third-party lab results confirm the plastic is free of estrogenic and androgenic activity.

Food-Grade Certification

The manufacturing process utilizes high-quality, food-grade plastics. This ensures the material is suitable for contact with food products intended for human consumption.

The Interaction Between Plastic and Honey

The Natural Wax Barrier

A common concern regarding plastic frames is the potential leaching of chemicals into the honey. However, biology provides a safeguard.

Preventing Direct Contact

Bees do not deposit honey directly onto the bare plastic. Instead, they first coat the internal surface of the plastic cells with their own beeswax. This ensures the honey is stored within a natural wax envelope, not against the plastic itself.

Understanding the Trade-offs

Potential for Bee Reluctance

While the plastic is safe, it is not natural to the bees. A practical drawback of using plastic foundations—including Flow Frames—is that bees may initially be hesitant to use them.

Overcoming Acceptance Issues

If you notice your colony is slow to build on the frames, this is a behavioral response rather than a safety issue. You can resolve this by applying a thin coat of beeswax to the surface of the frames. This encourages the bees to accept the artificial foundation and begin their work.

Ensuring Success with Plastic Frames

To get the most out of your Flow Frames while maintaining peace of mind, consider your specific priorities:

If your primary focus is Purity: Rest assured that the combination of non-leaching plastic and the bees' natural wax coating keeps your honey free from chemical contaminants.
If your primary focus is Hive Productivity: Monitor the frames closely when first installed; if bees ignore them, apply a thin layer of beeswax immediately to stimulate comb building.

The specifications of Flow Frame plastic are designed to balance the durability required for the harvesting mechanism with the safety standards required for organic food production.
