Wholesale PPSU Feeding Bottles 240 ml from China<\/h1>\n

PPSU is the premium bottle resin: it survives repeated sterilisation, resists staining and carries a medical grade reputation that polypropylene cannot match. It is also expensive enough that substitution is tempting, which shapes everything about how this category is bought: the resin, the nipple and the vent system are each a place where a cheaper part can be swapped in invisibly.<\/p>\n

\"PPSU<\/p>\n

The failures: bottles marked PPSU that are polypropylene with an amber tint, nipples that tear at the cross cut after a few sterilisation cycles, and vent systems that leak when the bottle is tilted, which is the complaint that floods a review page fastest.<\/p>\n

All three are testable with a kettle and a scale. The category context is in our wholesale baby products overview<\/a>.<\/p>\n

Resin, nipple and vent<\/h2>\n

Authentic PPSU is identifiable: it is naturally amber tinted, denser than polypropylene, and survives hundreds of steam sterilisation cycles without clouding. The identification method is simple, and the certificate behind the resin lot is the paper version of the same test.<\/p>\n

The nipple is where feeding actually happens. Silicone grade, flow rate at the stated age marking, and the cross cut that controls it are the working variables, and the vent system that stops colic is the engineering difference between a cheap bottle and a good one. Vent parts are small, multi piece and easy to assemble wrong, which makes the assembly instructions part of the product.<\/p>\n

Our minimum order is 1 piece, so the bottle, nipple and vent are sampled and approved before any production commitment. Production minimums follow the mould situation, and we confirm the figure in writing. Our sourcing service<\/a> screens the injection plants and the nipple specialists.<\/p>\n

How substitution happens and how to stop it<\/h2>\n

A bottle mould is a fixed asset, and the same mould can run any resin the operator loads. That flexibility is the opening for substitution: the bulk order is run in a cheaper resin, the certificate from the sample batch is reused, and nothing in a carton photograph reveals it. The defence is a resin lot certificate tied to your production dates, plus a density check on bulk units, both of which are routine.<\/p>\n

Nipple substitution is the same story one part smaller. Nipples are bought from specialists, and the silicone grade and flow tooling vary between them. Pin the nipple supplier and the flow tool to the order, then verify on the bulk lot. Our sample versus bulk guide<\/a> covers the general pattern.<\/p>\n
