The Ultimate Defense: High Barrier Three Side Seal Bags
Preserve Integrity: Engineering the Perfect Barrier Against Oxidation
For high-value food, medical, and industrial products, the greatest enemy is the atmosphere itself. Cailyn’s High Barrier Three Side Seal Bags are engineered to be a "fortress of integrity," utilizing advanced multi-layer foil and metalized laminates to provide a near-zero transmission rate for oxygen and moisture.
Why Technical Brands Choose Cailyn High Barrier Pouches?
- Precision OTR & MVTR Control: We meticulously engineer our film structures (PET/AL/PE or PET/VMPET/PE) to deliver industry-leading Oxygen Transmission Rates (OTR) and Moisture Vapor Transmission Rates (MVTR). This ensures your jerky stays crispy, your powders stay free-flowing, and your medical items stay sterile.
- Total Opacity & Light Block: For products sensitive to light degradation, our aluminum foil layers provide 100% opacity, blocking all UV rays and light-induced oxidation to maintain the potency and color of your contents.
- Heavy-Duty Hermetic Seals: A barrier is only as good as its seal. Our bags are designed with a wide sealing temperature window, ensuring 100% airtight, hermetic seals that withstand the pressures of global shipping and high-altitude transit.
- Versatile Industrial Applications: Beyond premium snacks like jerky and nuts, these high-barrier flat pouches are the trusted choice for diagnostic kits, specialized chemicals, and electronic components that demand a moisture-free environment.
