Glass Food Storage Containers with Glass Lids - 5 Pack 22oz Meal Prep

In this review of the Glass Food Storage Containers with Glass Lids the bottom line is simple: this 5 pack of 640ml/22 oz borosilicate glass containers is aimed at people who want a durable, chemical free meal prep system with consistent portion sizes. The single biggest reason to buy is the use of high quality borosilicate glass throughout the bowl and lid, which allows freezer-to-oven use without the lingering concerns of plastic leaching. It suits weekly meal planners, families who reheat food regularly, and anyone prioritizing reusable, oven-safe storage.

Key Features

• Borosilicate glass construction: The containers and lids are made from high-quality transparent glass so they withstand rapid temperature changes without warping or cracking.
• 640ml / 22 oz capacity: Each container holds about 2.7 cups, offering consistent portion control for meal prep and packed lunches.
• Glass lids with vent: Lids include an air vent to allow safe microwave use when opened, reducing pressure buildup during reheating.
• Silicone sleeve protection: The removable silicone sleeve adds grip and protects glass when stacking and transporting.
• Wide temperature range: Rated to tolerate extreme temperatures from around -40C to +560C for freezer to oven transitions.
• Durable lid snaps: Snaps are attached with an axis design intended to resist breaking in low temperatures.

Who It's For

This set suits people who prioritize plastic free storage: home cooks who prepare meals for the week, parents packing lunches, and anyone who wants oven and freezer safe containers that are also microwave compatible when vented. The 22 oz size is especially useful for single meals or portion controlled servings.

Those who should look elsewhere include users needing fully leakproof containers for long liquid transport (the vented glass lid design means careful handling is needed) and buyers who prefer very lightweight, collapsible plastic options for backpacking or long commutes.

Pros & Cons

Pros

• High quality borosilicate glass resists thermal shock and keeps food tasting neutral.
• Perfectly portioned 640ml size for meal prepping and calorie control.
• Stackable design with silicone sleeves saves cabinet space and aids grip.
• Dishwasher, microwave (vented), oven and freezer safe for versatile reheating and storage.

Cons

• Some customers report mixed durability of lids; tempered glass lids can crack under impact, so cautious handling is required.
• Lids combine glass with a plastic frame and a silicone seal that may need handwashing and occasional reseating to maintain an airtight fit.

Are these containers microwave safe?
Yes, the glass bowls and lids are microwave safe when the lid vent is opened or the lid is removed to prevent pressure buildup.

Can I use these in the oven?
The containers are oven safe, but remove the lid for extended high temperature use to avoid deforming the silicone sealing strip.
