Zip Top Reusable Platinum Silicone Breast Milk Storage - Set of 6

In this review of the Zip Top Reusable 100% Platinum Silicone Breast Milk Storage set, the bottom line is simple: this kit is for parents who want a plastic-free, durable option for storing expressed milk and then repurposing the bags for snacks later. The set's single biggest selling point is the use of 100% pure platinum silicone made in the USA, which avoids the chemical risks of typical plastic milk bags and stands up to repeated washing, freezing and warming. It is a practical choice for those prioritizing non-toxic materials and long-term reuse.

Key Features

• 100% platinum silicone: Made from pure non-toxic silicone that is free of BPA, lead, PVC, latex and phthalates to avoid chemical leaching into milk.
• Dishwasher and freezer safe: Bags are suitable for bottom-rack dishwasher cleaning, freezer storage and use with bottle warmers for daily convenience.
• Single-piece, plastic-free construction: The one-piece design stands up and keeps the top open so cleaning is easier than with multi-part plastic bags.
• Pour corners and writable surface: Poured corners reduce spills when transferring milk and the surface lets you write dates or notes directly on the bag.
• Includes freezer tray: The set includes six 6 oz bags plus a tray to keep bags organized and easy to arrange by date in the fridge or freezer.

Who It's For

This set works well for nursing parents who plan to pump regularly and want to reduce single-use plastic. It suits those who value chemical-free materials and an item that can be used beyond nursing for toddler snacks or frozen treats because of the durable silicone construction.

It is less ideal for caregivers who need guaranteed leakproof seals in all conditions or who prefer very rigid standing containers; some users report inconsistent sealing and occasional tipping when filled. If absolute leak certainty is essential, consider alternatives with different sealing mechanisms.
