Compare Food Storage Containers
Glasslock Premium 8-Cup/63oz Glass Food Storage Containers (2-Pack) scores higher on safety - here's why.
The most important dimensions, side by side.
Borosilicate glass is the gold standard for food-contact safety — chemically inert, handles extreme temperature changes, and zero chemical migration into your food.
Tritan is a premium BPA-free plastic with FDA food contact approval — safer than generic polypropylene but still a plastic that contacts your food directly.
Food-grade polypropylene lids are FDA-approved and BPA-free by nature — one of the safest and most well-characterized plastics for food contact.
The lid plastic is not precisely specified beyond "BPA-free Tritan with StainShield" — a transparency gap on a surface that directly contacts your food.
Confirmed BPA-free for both the borosilicate glass container and polypropylene lid.
Confirmed BPA-free — Tritan is a copolyester that never contains BPA as an ingredient.
No PFAS-free testing has been published for the lid seal — common across the entire category. The silicone gasket is not a PFAS risk by material nature.
Rubbermaid has not published PFAS-free testing for the Brilliance line's seal components.
Rated to 500°F — the highest oven temperature in this category. Handles freezer-to-oven transitions, roasting, and baking with ease.
Not oven-safe — Tritan plastic deforms above approximately 220°F. Containers are strictly for microwave, fridge, and freezer use.
Four-sided locking clips with silicone seal create a fully leakproof, airtight closure — safe for soups, sauces, and liquid transport.
The 4-latch locking clip system creates an airtight, leakproof seal — the most reliable closure mechanism in this comparison, ideal for transporting liquids.
Both glass container and lid are fully dishwasher safe.
Both containers and lids are fully dishwasher safe, with the container body going on any rack and lids on the top rack.
Four locking tabs require two hands to open and close — slightly frustrating for quick access but necessary for the leakproof seal.
Four snap-lock latches require two hands and moderate force to open and close — secure but not the quickest for repeated daily fridge access.
Rectangular containers stack neatly when lidded — efficient for fridge and pantry organization.
Uniform 3.2-cup containers stack perfectly and interlock — ideal for organized meal prep.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want the safest material combination available — borosilicate glass with disclosed food-grade PP lids
You need leakproof containers for transporting soups, sauces, or meal prep
You want the highest oven temperature rating in this category at 500°F
You prefer large 8-cup containers for batch cooking and family meal prep
You need shatter-proof, lightweight containers for packed lunches and daily transport

You meal prep in uniform portions and want stackable same-size containers
The main thing to know
At $15 per container, this is 5x more expensive per piece than the Pyrex Simply Store 12-pack. The premium is justified for families who prioritize material safety and transport, but budget-conscious buyers can get safe glass storage for much less.
Every surface that touches your food is plastic — the Tritan container body, the unspecified lid plastic, and the seal gasket. If minimizing plastic food contact is your priority, glass alternatives exist at comparable prices.
Skip this if you...
You are on a budget — at $15/piece, a full set of containers adds up quickly
You prefer one-handed convenience — the 4-tab locking mechanism requires two hands
You want a variety of container sizes — this set only includes 8-cup containers
You want to minimize plastic contact with your food — every food-contact surface here is plastic
You need oven-safe containers for fridge-to-oven cooking workflows
You care about full material transparency — the lid plastic type is not specified by Rubbermaid
