ERA‑Series Functional Barrier Coatings

EraPolyCare’s ERA‑Series coatings deliver high‑performance, water‑based barrier technology engineered for converters and brand owners advancing recyclable and sustainable packaging. Each formulation provides precise functional protection—oxygen, moisture, gas, or sealability—while maintaining clarity, flexibility, and compatibility with modern mono‑material structures.

Designed as drop‑in solutions for paper, film, and PET systems, ERA‑Series coatings eliminate the need for metallization or foil layers, enabling lightweight, circular, and regulatory‑compliant packaging across food, beverage, and dry‑goods applications.

Technology Overview

ERA‑Series coatings form smooth, uniform films with excellent adhesion to paper and polymer substrates. Their flexible, crack‑resistant structure maintains barrier integrity during converting, folding, flexing, and end‑use handling—unlike brittle metal‑oxide or aluminum layers.

Recyclability & Repulpability

When applied to paper, the coatings disperse in the aqueous phase during repulping, supporting fiber recovery without interfering with screening or separation. On PET, PE, and PP substrates, the coatings remain compatible with established recycling streams when used at appropriate coating weights.

Modular Barrier Design

ERA‑Series products can be used individually or combined to create dual‑barrier systems, such as pairing ERA‑OXY™ with ERA‑MOIST™ for oxygen + moisture protection in flexible packaging.

Sustainability & Compliance

• FDA Compliance: Formulated to meet FDA FCN 1179 food‑contact requirements.
• PFAS‑Free: No intentionally added PFAS; fully water‑based chemistry.
• Metal‑Free: Contains no aluminum or heavy metals.
• Recyclability of Coated Paper: Supports fiber recovery with Delta Reject of 16–18 % at 8 g/m².
• Biodegradability & Compostability: Achieves 90 % biodegradation within 30 days (ISO 14851).
• APR Design® Guide: Developed to align with APR Design® Guide principles for recyclability.
• Environmental Profile: Low‑VOC, water‑based formulations supporting recyclable and compostable packaging systems.

Final compliance with APR Design® Guide, ISO 14851 biodegradability, FDA FCN 1179, and other regulatory requirements must be validated for each specific package structure and end‑use. Recyclability outcomes depend on total package construction, layer ratios, and regional recycling capabilities.

EP‑OXY™ delivers superior oxygen barrier performance for dry goods and roasted products. Designed for converters seeking high barrier retention without metallization, it ensures product freshness and aroma stability.

Applications: Coffee, nuts, snacks, protein powders

Key Benefits:

• Excellent oxygen barrier for extended shelf life
• Compatible with recyclable mono‑material structures
• Maintains aroma and flavor integrity

EP‑MOIST™ provides outstanding moisture vapor resistance for frozen and refrigerated packaging. It prevents frost formation and maintains product texture during storage.

Applications: Frozen vegetables, ready meals, refrigerated foods

Key Benefits:

• Low MVTR for superior moisture control
• Excellent adhesion to PE and paper substrates
• Ideal for recyclable paper‑based trays

EP‑HYDRO™ enhances gas and moisture barrier properties of PET bottles through a thin, transparent coating layer. It reduces oxygen ingress and CO₂ loss, extending beverage shelf life.

Applications: Carbonated drinks, water bottles, functional beverages

Key Benefits:

• Improved gas barrier for PET packaging
• Transparent, flexible coating compatible with recycling streams
• Ideal for beverage converters seeking sustainability upgrades
  

EP‑SEAL™ replaces traditional aluminum‑laminated freshness seals with a fully recyclable paper‑based barrier. Designed for powders, spices, and spreads, it locks in freshness while supporting circular packaging goals. The coating system delivers moisture and oxygen resistance comparable to foil, without compromising recyclability or food‑contact compliance.

Key Benefits:

• Metal‑Free Construction: 100 % paper‑based, compatible with recycling streams
• Superior Barrier Performance: Maintains dryness and aroma integrity
• Eco‑Optimized Design: Supports brand sustainability targets and regulatory compliance
• Customizable Surface: Printable for branding, traceability, and tamper‑evidence
