Hey everyone! As someone who works closely with all kinds of plastic containers at Reliancepak, I get asked a lot about the difference between airtight and non-airtight options. It’s a super important question because the right container can really make a difference in how you store your food, organize your stuff, and just make your life a little easier. So, let’s break it down!
What Makes a Plastic Container “Airtight,” Anyway?
When we say a plastic container is “airtight,” we mean it’s designed to create a really tight seal. This seal is meant to keep air and moisture from getting inside. Usually, you’ll see this achieved with a combination of a lid that fits snugly and a gasket (often made of silicone or rubber). The whole point is to create an environment inside the container that slows down oxidation, which can make food go bad faster, and prevents the growth of nasty stuff like bacteria and mold.
How Can You Test if a Plastic Container is Really Airtight?
Okay, so a container says it’s airtight, but how can you be sure? Here are a few simple tests I use myself:
- The Water Inversion Test1: Fill the container with water, close the lid nice and tight, and then turn it upside down over your sink. If any water leaks out, it’s definitely not airtight. This is the easiest and most reliable test.
- The Visual Inspection2: Give the lid and the gasket a really good look. Check for any cracks, tears, or gaps. Even a tiny imperfection can mess up the seal. I’ve seen some containers where the gasket wasn’t seated properly from the factory – easy to miss if you’re not looking closely.
- The “Suck” Test (for some containers): Some of the more high-end airtight plastic containers are designed to create a bit of a vacuum as you seal them. As you close the lid, you might actually feel it “suck” into place. This is a good sign that the seal is working effectively. This isn’t common for all containers, though.
What About Non-Airtight Plastic Containers? What Are They Good For?
Okay, so airtight is great for some things, but what about non-airtight plastic containers? Well, they don’t create that super-tight seal we talked about. The lids might snap on loosely, or just rest on top. They’re still totally useful, just not for everything.
When Should You Use a Non-Airtight Plastic Container?
Don’t write off non-airtight plastic containers! They’re perfect for:
- Short-Term Leftovers: If you’ve got some leftovers from dinner and you’re planning to eat them for lunch tomorrow, a non-airtight container is usually just fine. You’re not worried about long-term preservation in this case.
- Dry Goods That Are Pretty Shelf-Stable: Things like crackers, chips, pretzels – stuff that doesn’t really need a completely airtight environment to stay good. You just want to keep them from getting crushed or spilled.
- Organizing Non-Food Items: This is where non-airtight plastic containers really shine! They’re awesome for organizing craft supplies, office supplies (paperclips, rubber bands, etc.), small toys, or even hardware like screws and nails.
- Microwaving (Sometimes): Some non-airtight plastic containers are specifically designed to be microwave-safe. Always look for the “microwave-safe” symbol on the bottom of the container before you nuke anything. And usually, you’ll want to vent the lid slightly to prevent steam buildup.
Airtight vs. Non-Airtight Plastic Containers: Let’s Compare!
To make it even clearer, here’s a table that compares the key differences between airtight and non-airtight plastic containers:
| Feature | Airtight Plastic Containers | Non-Airtight Plastic Containers |
|---|---|---|
| Seal Quality | Creates a complete, airtight seal | Does not create a complete seal |
| Protection Level | Excellent protection against air, moisture, and pests | Limited protection against air and moisture |
| Best For: | Long-term food storage, maximizing freshness | Short-term storage, organizing non-perishable items |
| Common Uses: | Food storage, preserving delicate items | Takeout containers, organizing, storing craft supplies |
| Price Point: | Generally more expensive | Generally less expensive |
| Reliancepak Pick: | Our Premium FreshSeal Series for ultimate preservation | Our Budget Basics line for everyday storage and organization |
Why Does Airtightness Really Matter for Food?
You might be thinking, “Okay, airtight is nice, but why does it matter so much for food storage?” Here’s the deal:
- Oxidation is the Enemy: Air causes food to oxidize, and oxidation is what leads to those changes in color, flavor, and texture that make food taste stale or just plain bad. Airtight containers minimize oxidation, so your food stays fresher longer. Think about how quickly an apple slice turns brown when you leave it out – that’s oxidation in action!
- Bacteria and Mold Love Moisture: Bacteria and mold need moisture to grow. Airtight containers reduce the amount of moisture that can get to your food, which slows down their growth and helps prevent spoilage.
- Pests Can’t Get In: Nobody wants bugs or rodents getting into their food. Airtight containers create a barrier that keeps those unwanted guests out.
What Kinds of Food Really Benefit from Airtight Storage?
Some foods benefit from airtight storage way more than others. Here are a few key examples:
- Dry Goods (Flour, Sugar, Rice, Pasta, etc.): These staples can easily become stale, absorb odors, or attract pests if they’re not stored properly. Airtight containers are essential for keeping them fresh and pest-free.
- Coffee and Tea: If you’re a coffee or tea lover, you know how important it is to preserve the flavor and aroma. Airtight containers are a must for keeping your beans and leaves fresh.
- Cheese and Deli Meats: These items dry out super quickly when exposed to air. Airtight containers will help them stay moist and delicious.
- Leftovers (Most of the Time): While a non-airtight container is okay for very short-term leftovers, airtight containers are the way to go for anything you’re planning to eat a few days later. They’ll prevent the leftovers from drying out and absorbing weird odors from the fridge.
Choosing the Right Plastic Container: Things to Keep in Mind
Okay, so you know the difference between airtight and non-airtight. Now, how do you choose the right plastic container for the job? Here are a few key things to consider:
- Material: Always look for containers made from food-grade plastic that’s BPA-free. At Reliancepak, we’re super picky about using only the safest materials for our containers. Your health is our top priority!
- Size and Shape: Think about what you’ll be storing in the container. Do you need something small and round for individual portions, or something large and rectangular for a whole casserole? Choose a size and shape that makes sense for your needs.
- Lid Design: The lid is crucial! You want something that’s easy to open and close, but still provides a secure seal (especially for airtight containers). Check the latching mechanism or the gasket to make sure it’s well-designed.
- Durability: Nobody wants a container that cracks or breaks after a few uses. Look for containers that feel sturdy and well-made. Read reviews to see what other people are saying about the container’s durability.
- Ease of Cleaning: Let’s be honest, nobody loves washing dishes. Choose containers that are easy to clean, either by hand or in the dishwasher. Check to see if the lids are dishwasher-safe as well.
- Your Specific Needs! This is the most important factor of all. Think about how you plan to use the containers. Are you primarily storing food for long periods of time? Organizing small items? Microwaving leftovers? Your answers to these questions will determine whether you need airtight containers or if non-airtight ones will suffice.
