Tea packaging requires an aroma barrier against essential oils and a light barrier against UV degradation. The material composite determines flavour retention and best-before length.
PET12 / AL7 / LDPE110 — aluminum high barrier
Three-layer composite of 12 microns PET (print side), 7 microns pure aluminum as a barrier layer and 110 microns LDPE seal layer. OTR < 0.1 cm³/m²·24h, WVTR < 0.1 g/m²·24h, complete aroma and light barrier. Standard for high-quality black tea, green tea, matcha with a best-before date of up to 36 months.
Kraft paper 50g / AL7 / LDPE — paper-aluminum hybrid
Outer side of 50 g/m² natural or dyed kraft paper, behind it 7 microns aluminum lamination as a barrier layer, and an LDPE seal seam on the inside. Visually artisanal, technically almost identical barrier. Popular for organic tea brands, artisan teas and sustainability-oriented brand positioning.
PE / EVOH / PE — mono-PE recyclable
Mono-material composite on a polyethylene basis with a thin EVOH barrier layer (< 5 % share). OTR approx. 1–3 cm³/m²·24h — sufficient for tea with a best-before date of up to 18 months. NIR-detectable in the PE recycling stream, compliant with RecyClass design guidelines, PPWR-compliant from 2030.
OPP / metallised / PE — premium look with high barrier
With a vacuum-metallised intermediate layer (no solid aluminum). Aroma and light barrier almost 100 %, visually high-gloss. Suitable for premium tea ranges with a visual brand presentation.
Kraft paper / PLA — compostable
Composite of a kraft paper outer side and a polylactic acid inner film, certified in accordance with EN 13432 for industrial composting. For direct marketers and farm shops with quick tea turnover. Not suitable for a long best-before date — PLA degrades under prolonged moisture exposure.
Zip and tin-tie closures
Optional PE zip closures for repeated opening by consumers — standard for premium tea. The tin-tie closure (paper-wrapped wire) is classic for artisan teas in side gusset bags. Both components are certified food-grade.
All materials are certified for food contact in accordance with EU Regulation 10/2011. We supply the declaration of conformity (PIM) with every order on request.
