KO Keeping food fresh in the refrigerator requires not only maintaining the right temperature, but also choosing the right storage container. The right food container can keep food in the best condition and effectively organize the refrigerator. However, there are so many containers of different materials on the market, how do you choose?
Purecook, un professionnel wholesale food container supplier, will introduce you in detail.
What Should Refrigerator Food Storage Containers Have?
Excellent sealing: This is the most important thing! Excellent sealing can effectively lock in moisture, prevent food from dehydration and shrinkage, isolate odors from crossing, and delay bacterial growth. Sealing strips or reliable snap-on designs are especially important.
Food-safe materials: The container itself must be absolutely safe and non-toxic. Use plastics marked “food grade”, preferably those that can provide BPA-free certification and comply with FDA or LFGB certification.
See-through: Transparent food containers or those with clear labels allow the contents to be seen at a glance, effectively preventing food from being forgotten in the corner.
Optimized space utilization: Square containers take up less space than round ones, and the stackable design can significantly improve refrigerator utilization.
Strong temperature adaptability: The container needs to have good temperature adaptability. Due to the possible frequent taking out and putting in, the food container is required to be able to adapt to large temperature changes and not easily crack in a low temperature or freezing environment.
Comparison of Food Containers of Different Materials
| Matériau | Excellent Sealing | Food-Safe Material | See-Through (Transparency) | Optimized Space Utilization | Strong Temperature Adaptability | Recommendation Rating |
| Glass | Good sealing with airtight lids; reliable snap-on or silicone seals | Non-toxic, BPA-free, generally very safe | Transparent, easy to identify contents | Usually square or rectangular shapes available; stackable | Excellent thermal shock resistance; handles fridge to oven well | ⭐⭐⭐⭐⭐ (Highly recommended) |
| Stainless Steel | Sealing depends on lid design; can achieve excellent snap-on airtightness | Non-toxic, BPA-free, very safe | Not transparent, usually opaque | Often comes in stackable rectangular/square shapes | Excellent temperature resistance, no cracking risk | ⭐⭐⭐⭐⭐ (Highly recommended) |
| Plastic (Food Grade) | Varies by brand; good sealing with silicone or gasket lids available | Must be certified food grade, BPA-free preferred | Usually transparent or semi-transparent | Available in many shapes including square stackables | Moderate; some plastics can crack under extreme cold or heat | ⭐⭐⭐ (Moderately recommended) |
| Silicone | Usually good sealing with flexible lids or snap-on designs | Food-grade silicone is non-toxic and BPA-free | Semi-transparent or translucent | Flexible and collapsible for space-saving | Excellent temperature adaptability; freezer and microwave safe | ⭐⭐⭐⭐ (Great for flexible use) |
| Ceramic | Sealing often weaker; depends on lid design, less common airtight lids | Non-toxic, food-safe glazed ceramic | Usually opaque, some glazed with clear lids | Typically not optimized for stacking; heavier shapes | Good thermal retention but fragile under temperature shock | ⭐⭐ (Use with care) |
Choosing the Best Container for Your Needs
| Need | Recommended Container |
| Long-term fridge storage | Glass or stainless steel |
| On-the-go meals | Stainless steel or plastic |
| Space-saving | stainless steel, silicone or plastic |
| Freezing leftovers | Glass or stainless steel |
| Serving from fridge to table | Ceramic or glass |
Suggestion
First choose glass or stainless steel: For safety, peace of mind, and longevity, glass and stainless steel containers are the best all-purpose choice for refrigerator storage.
Reasonable use of plastic food containers: suitable for light needs and short-term food storage. Pay attention to the recycling mark on the bottom and replace old and scratched boxes in time.
Stainless steel is the first choice for freezing: When freezing meat, seafood and other ingredients, stainless steel containers are an ideal choice, especially for long-term refrigeration or scenarios that require rapid cooling.
Keep raw and cooked food separate: No matter which container you use, keeping raw and cooked food separate is the key!
Ensure sealing: Good sealing performance can isolate odors and ensure the freshness and safety of food.
