Aromatic Barrier Material Selector
Select from precision-engineered laminates designed to neutralize oxidation. Our films protect delicate tea polyphenols and essential oils from light and moisture.
ALU-Foil Laminate
PET / ALU / PE
The gold standard for long-term storage. The pure aluminum layer provides a near-zero OTR (Oxygen Transmission Rate) and total opacity against UV rays.
Total Light & Oxygen Block
VMPET Composite
MOPP / VMPET / PE
Optimized for cost-effective retail packaging. Provides excellent moisture resistance with a high-gloss metallic finish that enhances shelf appeal.
Superior Moisture Barrier
Compostable PLA
Kraft / PLA / NKME
A plastic-free alternative for organic tea brands. Fully home-compostable materials that maintain aromatic integrity without environmental impact.
100% Biodegradable Path
Clear Barrier KPET
KPET / LLDPE
Ideal for showcasing premium whole-leaf teas or blooming teas. Combines crystal-clear transparency with a specialized PVDC coating for gas protection.
High Transparency & Aroma Lock

Harvest Freshness.
Engineering Precision.
Our professional tea packaging systems are audited for sensory consistency. We simulate long-term storage and export logistics, ensuring that the tea’s volatile flavor profile remains intact from the plantation to the consumer's teapot.
Terpene Retention Analysis
We provide gas chromatography testing to ensure that 98%+ of your tea’s natural aromatic compounds are preserved after 12 months.
Fresh-Valve Systems
One-way degassing valves for fermented teas (like Pu-erh) to allow natural off-gassing while preventing oxygen ingress.
UV Barrier Certification
Our opaque and metallized structures filter out 99.9% of harmful light rays, preventing the "hay-like" oxidation of green teas.
Tea Preservation
Technical FAQ.
Preserving premium tea requires more than a standard pouch. It demands aroma-lock barriers, total UV shielding, and de-humidification technology—engineered to keep leaves farm-fresh.
"Protection of Origin"
Industrial Grade Tea Packaging Solutions
How do you prevent the loss of tea fragrance over time?
🍃Fragrance loss is caused by the migration of essential oils through the film. We utilize high-density ALU-foil or EVOH barrier layers that act as a "scent-vault," keeping 99% of the tea’s natural terpenes and aromatics trapped inside the pouch.
Is your packaging safe for vacuum or nitrogen flushing?
💨Absolutely. Our structures are engineered for high-vacuum integrity. For delicate whole-leaf teas, our films support Nitrogen (MAP) flushing to displace oxygen, preventing the enzymatic browning of green and white teas.
Do you offer food-safe certified materials for international export?
🌍Yes. All our tea laminates are FDA and EU food-grade compliant. We use solvent-free lamination processes and low-migration inks, ensuring no chemical odors interfere with the subtle notes of your tea.
Solving the Realities of
Premium Tea Distribution
Tea is a highly sensitive agricultural product. Humidity, oxidation, and cross-contamination can destroy your brand's reputation. At Sengelin, we provide the technical barrier solutions to ensure your harvest tastes the same in the consumer's cup as it did at the garden.
"Our green tea is turning brown and losing its fresh profile."
Oxygen ingress is the enemy of polyphenols. We apply high-barrier metallized coatings that reduce OTR to negligible levels, stopping oxidation in its tracks and extending shelf life by up to 24 months.
"Tea leaves are absorbing moisture and clumping during shipping."
Tea is naturally hygroscopic. Our multi-layer co-extruded polymers provide a superior moisture vapor barrier (MVTR), preventing the leaves from absorbing ambient humidity during sea transit or humid storage.
"Tiny tea dust is contaminating the seal area and causing leaks."
Tea fannings and dust often interfere with heat seals. We utilize specialized "Seal-Through-Contamination" resins that melt around fine particles to maintain a 100% hermetic, air-tight closure.
