How to Specify a Private Label Baby Bottle

The eight decisions that fix cost, lead time and complaint rate on a private-label baby bottle: material, neck, valve, teat flow, packaging and test scope.

Start with the neck, not the shape

The neck diameter decides which teats, collars and breast pump adapters fit the bottle for the rest of its life. Wide-neck is easier to fill and clean and takes a wider teat base; standard-neck is cheaper per unit and packs more tightly. Whichever you choose, it constrains every accessory you sell afterwards, so decide it before you look at the silhouette.

Material follows how it will be cleaned

PP is the volume material for feeding items: light, food-contact grade and cheap to mould. Where a buyer wants glass clarity or full sterilising tolerance, the tooling and the freight both change. Check the cleaning instruction you intend to print before you fix the material, because a dishwasher-safe part and a steam-sterilisable part are not the same part.

The valve is where complaints come from

Colic valves and anti-leak seals are the two parts that generate returns. A silicone seal is specified for elasticity, not hardness, and it must be checked at assembly rather than after packing. Ask any supplier at which inspection stage the seal is verified; if the answer is only pre-shipment, faults are being caught after they are expensive.

Teat flow rates are a range decision

One bottle usually means three or four teat flow rates across the age range. Decide early whether the flow rates are sold in the box or as accessories, because it changes the colour box dieline and the carton quantity.

Packaging is quoted with the product

Colour box for retail shelf presence, OPP bag where cost matters more. We supply the dieline and you supply print-ready artwork including your barcode. Getting the dieline before the artwork saves a full revision cycle.

Fix the test scope with the market

Test scope for a feeding item is set by the destination market. Confirm the market before you request a quote, so the certificate work is priced into the first order rather than discovered during customs clearance.

Sign a golden sample

A signed golden sample is what the QC team inspects against at all five stages. It is also the only reference that settles a dispute about a later batch, which is why both sides sign it.
