Food Container Sets
$29.99$19.99
🍼【2-IN-1 DESIGN – REMOVABLE SLIDER FOR EASY SEALING】
The patent-pending detachable plastic slider (ABS-HI121H) lets you seal with a single finger swipe – no struggling with zipper tracks. Squeeze the ends to open. The slider is reversible (works from either side). Remove it for traditional press-to-seal closure. Best of both worlds.
👶【BREAST MILK READY – FREEZER TO BOTTLE】
Specifically designed for pumping moms. Fill, seal, lay flat in freezer. Thaw under warm water. Pour directly into a bottle – the wide mouth prevents spills. Holds 240ml or 360ml (standard feeding sizes). Pre-sterilized and ready to use. BPA-free and phthalate-free.
🌡️【DUAL TEMPERATURE ZONES – KNOW YOUR LIMITS】
The silicone body handles -40°C to 200°C (-40°F to 392°F) – freeze, microwave, boil. Important: The ABS plastic slider handles -20°C to 90°C (-4°F to 194°F) . Remove slider before microwaving or boiling. Simple, safe, smart.
🔒【100% LEAKPROOF – HANGING HOLE DESIGN】
Double-secure seal prevents leaks even with thin liquids like breast milk or soup. The built-in hanging hole lets you:
Hang upside down to dry after washing
Hang on a hook in the fridge for easy access
Thread a string for travel organization
🎨【5 SIZES + 5 COLORS – FAMILY ORGANIZED】
Sizes: 240ml, 360ml, 500ml, 1000ml, 1500ml
Colors: Transparent, Cool Blue, Soft Green, Water Pink, Serene Blue

The Only Bag That Does Double Duty: Breast Milk + Family Food Storage
Most moms buy disposable plastic breast milk bags – use once, throw away, buy again. That's hundreds of bags per baby.
BUYUER created a better way.
A reusable silicone bag that stores breast milk safely, then transitions to snack duty for toddlers, then lunch duty for parents. One bag. Years of use.
🔧 The 2-in-1 Slider System – Genius Simplicity
Feature | How It Works |
|---|---|
With slider | Pinch the ends of the plastic bar, slide across – sealed in 1 second |
Without slider | Remove slider, press the silicone track shut with fingers |
To open | Squeeze the two ends of the slider – it pops open |
Reversible | Slider works from either left or right side (不分左右) |
The slider is removable for a reason: Take it off before microwaving or boiling. The silicone handles heat perfectly. The slider goes back on after cooling.
👩🍼 For Breastfeeding Moms – Designed With You in Mind
Why BUYUER beats disposable bags:
Disposable Plastic Bags | BUYUER Silicone | |
|---|---|---|
Cost per use | $0.30 – $0.50 (one time) | $0.01 (1000+ uses) |
Leak risk | High – seams burst | Near zero |
Pouring | Floppy, spills easily | Stands upright, wide mouth |
Freezer space | Bulky | Lays flat |
Environmental cost | Landfill forever | Zero waste |
Milk storage tips:
Fill to 240ml or 360ml line (don't overfill – milk expands when frozen)
Lay flat in freezer to create "bricks" that stack
Thaw in refrigerator overnight or under warm running water
Remove slider before thawing in warm water
🍱 Beyond Breast Milk – Family Food Storage
Once your little one weans, these bags don't go to waste. Use them for:
Size | Best For |
|---|---|
240ml | Baby purees, salad dressing, travel shampoo |
360ml | Snacks, nuts, toddler crackers |
500ml | Sandwich, cut fruit, rice |
1000ml | Leftovers, pasta, cereal |
1500ml | Marinated chicken, soup portions, family meal prep |
🌡️ Temperature Guide – Read This Before Using
Silicone body only (remove slider):
Freeze: -40°C (-40°F) – safe for long-term storage
Microwave: Up to 200°C (392°F) – vent the seal slightly
Boil: 100°C (212°F) – for sterilization
With ABS slider attached:
Safe range: -20°C to 90°C (-4°F to 194°F)
Do not microwave or boil with slider on – remove it first
Simple rule: Slider for room temperature and fridge only. Remove for heat.
💧 Leakproof Design – Tested With Liquids
We filled these bags with water, sealed them, and turned them upside down for 24 hours.
Zero drops.
The combination of silicone track + plastic slider creates a compression seal that plastic ziplocs can't match. Safe for:
Breast milk in diaper bags
Soup in lunch boxes
Smoothies for the gym
Marinades in the fridge
Note: If using without the slider, don't store upside down with thin liquids. The slider provides the extra compression for leakproof liquid storage.
🧼 Easy Cleaning – Hanging Hole For Drying
Hanging hole does triple duty:
Hang upside down on a hook to air dry completely
Hang on fridge organizer for quick access
Thread with string or carabiner for camping/travel
Cleaning methods:
Dishwasher: Top rack, remove slider first
Hand wash: Turn inside out, scrub with sponge, rinse
Sterilize: Boil for 3 minutes (remove slider)
Deep clean: Baking soda + warm water, soak for 30 minutes
The hanging hole lets water drain out – no more wet bags sitting on your counter.
