The shelf life of baby bottles is the time during which the product remains safe, hygienic, and functionally effective for feeding. In MOYUUM’s case, this matters because their bottles and accessories are exposed to repeated sterilization, frequent use, and constant temperature fluctuations, which slowly break down the materials, even premium ones like PPSU plastic and platinum silicone.
If not replaced on time, worn bottles or pacifiers can:
-
Harbor invisible bacterial buildup in scratches and micro-tears
-
Develop leaks, weak seals, or nipple collapse
-
Pose choking hazards from torn silicone
-
Cause feeding disruptions due to changes in flow rate.
Shelf Life of MOYUUM Bottles
The official shelf life of MOYUUM bottles is 2 years from the manufacturing date, as long as the product remains unopened, properly stored, and unused.
However, once in use, the recommended replacement interval depends on material type, usage habits, and exposure to sterilization, especially for parts like nipples and caps that endure direct stress and wear.
What Materials Are MOYUUM Bottles & Accessories Made Of?
MOYUUM uses premium, medically safe materials designed for durability and infant safety. However, even the best materials degrade over time due to repeated use, sterilization, and exposure to heat or friction.
Here's a breakdown of materials used in MOYUUM bottles and accessories, along with how they impact shelf life and replacement frequency:
1. Bottle Body: PPSU Plastic or Borosilicate Glass
-
PPSU (Polyphenylsulfone)
-
Heat resistant up to 180°C
-
BPA-free, high-impact tolerance
-
Shelf life: 6–12 months (depending on usage)
-
Tends to discolor or scratch with heavy use
-
Common in MOYUUM 270ml or 200ml PPSU bottles
-
Borosilicate Glass
-
More stable, less prone to wear
-
Can last 1–2 years if not cracked or dropped
-
Ideal for parents who prefer longer-lasting, sterilizer-safe options
-
MOYUUM’s glass bottles offer better shelf life, but are breakable
2. Nipples and Pacifiers: Platinum Silicone
-
Made from medical-grade platinum silicone, not industrial silicone
-
Soft, stretchable, and naturally BPA-, PVC-, and phthalate-free
-
Shelf life: 2–3 months for nipples, 1–2 months for pacifiers
-
Silicone can degrade with frequent boiling or UV sterilization
-
Prone to micro-tears or softening with bite pressure
3. Handles, Caps, and Straw Parts: Food-Grade PP or Silicone
-
Handles and straw parts use FDA-approved food-grade plastic or silicone
-
Caps often made of polypropylene (PP)
-
These parts last longer (up to 12 months), but should still be monitored for cracks or leaks
How Often Should You Replace MOYUUM Nipples & Pacifiers?
MOYUUM recommends replacing silicone nipples every 6 to 8 months, even if there are no visible signs of wear. This is because platinum silicone, while medically safe and BPA-free, naturally degrades with repeated sterilization, exposure to high temperatures, and mechanical stress during feeding.
Parents often search for answers to “how long do baby bottle nipples last?” or “when to replace silicone nipples”, but the answer is more nuanced than a date on the calendar.

Over time, the material softens, stretches, or loses elasticity, which alters milk flow, creates nipple collapse, and may lead to feeding interruptions.
Pacifiers, made from the same platinum silicone, degrade faster due to continuous chewing, mouthing, and saliva exposure. Even when they appear intact, they should be replaced every 2 to 3 months. If a pacifier becomes sticky or glossy, it’s a clear sign that silicone fatigue is setting in.
Using UV or steam sterilization daily accelerates material breakdown, especially around the nipple base and pacifier shield. This degradation can lead to micro-tears, which may harbor bacteria invisible to the eye. These are high-risk zones in prolonged use.
Do MOYUUM Bottles Expire If Unused or Unopened?
MOYUUM bottles have a shelf life of 2 years if stored properly, sealed, away from heat and humidity. Though unused, materials like PPSU and silicone may degrade with time. Always check the manufacturing date on packaging.
FAQS
Can I use a MOYUUM bottle after two years if it’s still sealed?
Technically yes—MOYUUM bottles have a shelf life of 2 years, but only if the packaging is intact and stored away from heat and humidity. If the bottle smells odd or shows surface changes, discard it.
Is it okay to use a nipple that looks fine after 8 months?
No. Even if the nipple looks intact, silicone fatigue may cause internal degradation, leading to micro-tears, inconsistent milk flow, or collapse. Replace every 6–8 months.
Why is my PPSU bottle turning yellow? Is it unsafe?
PPSU discoloration is common with sterilization and doesn’t always mean it’s unsafe. But if yellowing is combined with scratches or leaks, it’s time to replace.
Can I pass down MOYUUM bottles to a second baby?
Only the glass or PPSU body, never nipples or pacifiers. Replace all silicone parts and sterilize thoroughly. If the bottle is over 2 years old, replacement is recommended.
Are there expiry dates printed on MOYUUM bottles?
MOYUUM doesn’t print “expiry” but includes manufacturing dates. Count 24 months from that date for safe storage.
