Cubkins Smart Temp-sensing BREAST MILK STORAGE BAGS (250ml) | Pre-Sterilized & Leak-Proof
The Smarter Way to Build Your Liquid Gold Stash
The only bag that tells you when it’s safe to feed.
Return to work with zero guilt. Our pre-sterilized, double-sealed, high-capacity bags feature a built-in thermal sensor that removes the guesswork for nannies and dads. Protect your "liquid gold" from leaks, bacteria, and overheating.
- 250ml High Capacity: Holds 30% more than standard bags (8oz) – perfect for high-supply days.
- Intelligent Thermal Sensor: Changes color to show the optimal nutrient-preserving temperature.
- Zero-Contamination Spout: Separate tear-away spout keeps milk away from zipper germs.
- Leak-Proof Double Zipper: Reinforced double-zipper seal prevents freezer accidents.
- Pre-Sterilized: 100% Ready to use out of the box.
Leaving your baby is hard enough; worrying about their feed shouldn't be. Whether it's your mother-in-law or a new nanny handling the feeding, our Smart Sensor acts as your voice in the room. It gives them a simple visual cue to ensure nutrients aren't destroyed by overheating. It’s not just a bag; it’s peace of mind.
Our thermochromic indicator changes color instantly based on milk temperature. No batteries, no thermometers needed.
🟣 Purple: Cold (< 36°C)
🔵 Blue: Perfect Feeding Temperature (36°C - 40°C)
⚪ White: Too Hot (> 40°C)
The "One-Way" Hygiene System:
Standard bags force you to pour milk out past the same zipper you touched with dirty fingers. We fixed that.
- Fill through the wide top zipper.
- Pour by tearing the separate side spout.
Your milk never touches the entry point again.
High Capacity (250ml / 8oz):
Most bags stop at 180ml. We give you extra room for those high-volume morning pumps, reducing the number of bags you need to buy.
Leak-Proof Dual Track Seal:
Our reinforced double zipper creates a vacuum-like lock. No drips, no bursts, no crying over spilt milk.
Stress-Free Labeling:
The writing tab is positioned above the fill zone. You can write the Name, Date, and Time clearly without puncturing the bag or writing on a bumpy liquid surface.
Free Dual-Ended Marker:
Stop hunting for a pen. Every box comes with a specialized marker featuring two tips – fine for details and thick for high-visibility dates.
At Cubkins, our philosophy is 'Zero Plastic' for feeding. However, when it comes to long-term freezer storage of breast milk, safety and sterility are non-negotiable. While reusable silicone is great for fresh food, breast milk requires a sterile, air-tight barrier to prevent bacterial growth and freezer burn during months of storage.
Additionally, To preserve antibodies, breast milk needs to freeze fast. Silicone is an insulator (blocks cold), while our Medical-Grade LDPE allows for rapid flash-freezing, locking in nutrients instantly.
We use Medical-Grade LDPE & PET 7 that is BPA-free, FDA-approved, and pre-sterilized. It is the safest way to build a 'milk bank' for your baby while ensuring zero contamination.
The "Rule of 6s" for Working Moms:

Safety Warnings:
- ⚠️ Do Not Microwave or Boil: Thaw in the refrigerator or under warm water.
