Dairy + ESL milk
Dairy preform manufacturer & dairy PET preform factory. Aseptic + ESL validated.
Delta El Nile for Industry supplies dairy-grade PET preforms validated for aseptic filling (Tetra Pak A3, Sidel Aseptic, SIG combiblock) and Extended Shelf Life (ESL) cold-chain dairy. 32/15 neck preforms span 11g–32g for liquid milk and yogurt drinks; 38mm preforms cover larger pack formats. Halal and Kosher certificates on file; FSSC 22000 V6 quality program throughout.
Why Delta El Nile for Industry
Why dairy procurement teams choose Delta
Aseptic-line validated, not theoretical
Our 32/15 dairy preforms have validation reports on Tetra Pak A3, Sidel Aseptic Combi, and SIG combiblock systems — meaning the dimensional tolerances and the surface preparation have been confirmed by actual filling-line runs, not just spec sheets. Validation reports available under NDA.
ESL cold-chain shelf life up to 28 days
ESL dairy needs a preform with tight oxygen barrier characteristics, controlled crystallinity at the neck, and surface profile compatible with high-speed capping at 4 °C. Our standard 32/15 and 38mm dairy grades meet this — we don't need a special material order.
Halal and Kosher certified
MENA dairy markets require Halal certification on every packaging component. Export to Israel, certain US and European retailers, or kosher-certified product lines requires Kosher certification. Delta holds both continuously; certificates are issued per shipment without additional lead time.
Lightweighting in a regulated category
Reducing a dairy preform by 1g is harder than reducing a CSD preform — the regulatory and shelf-life constraints are tighter. We've executed 11g → 9.5g programs on 32/15 SKUs with full aseptic-line re-validation. See our shelf-life case study for the methodology.
Common questions
What's the smallest dairy preform you make?
11g on 32/15 neck for 200-250ml drinking yogurt and milk shot products. The lower end is constrained by drop-test and capping integrity, not by our tooling — we can mold lighter but the bottling line typically struggles below 11g.
Can you supply preforms for fermented dairy like kefir or laban?
Yes. Fermented dairy has a higher CO2 evolution profile than fresh milk, which stresses the cap-seal interface. We've shipped 32/15 preforms into kefir and laban programs in Saudi Arabia and Egypt; the spec includes a slightly thicker neck wall vs standard milk to handle 2-3 bar internal pressure.
Do you offer color-matching for branded dairy programs?
Yes — opaque white, light blue, and brand-tinted dairy preforms are standard offerings. We use only EFSA + FDA positive-listed colorants. Pantone-matched custom colors are available with a one-time tooling charge and 3-4 week lead time for the colorant batch certification.
What's the MOQ for dairy preforms?
From existing 32/15 tooling: 250,000 pieces per SKU per order (one Small Carton pallet group). For new colorways or weight variants on existing geometries, MOQ is 500,000 pieces to amortize the colorant qualification cost. Larger jumbo-box orders scale up to 6,000+ pieces per box.
