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 (Sidel Aseptic and Krones lines) 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 certificate on file; Kosher on request; 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 Sidel Aseptic Combi and Krones 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 certified; Kosher on request
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 is Halal certified; Kosher certification is available on request. Halal 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?
Minimum order is one full 40 ft container or one full truck; for a smaller quantity, ask us and we check whether the SKU is in stock. For a new colour, the minimum depends on the colour: tell us your shade and we confirm it. Larger jumbo-box orders scale up to 6,000+ pieces per box.
