05 · Feature Solution
High-Barrier Freshness Packaging
UHS high-barrier composite that seals out oxygen, moisture and UV — keeping every note intact.
05 · Industry Pain Points
Why buyers come to usOxygen ingress
Standard kraft + PE layers transmit 50-150 cc O₂/m²/day — fatal for fresh-roast coffee or dried seafood.
UV degradation
Aroma oils and natural pigments break down quickly under retail lighting without UV-blocking outer liner.
Seam integrity
A weak side seam defeats the whole barrier — production method matters as much as the substrate itself.
05 · Core Techniques
Fine techniqueUHS composite
Triple-layer structure: kraft / aluminium / sealant film, hermetically bonded.
Welded side seam
Ultrasonic seam welding that eliminates micro-channels for oxygen ingress.
Easy-peel membrane
Pre-scored inner membrane for clean opening without compromising the seal.
Pressure test
Every batch leak-tested at 50 kPa for 30 s before packing.
