Hey there! As a supplier of oxygen packs for food storage, I often get asked if these oxygen packs can be used with plastic containers. It's a super common question, and today, I'm gonna break it down for you.
First off, let's talk about what oxygen packs for food storage are and how they work. Oxygen packs, also known as oxygen absorbers, are little packets filled with materials that react with oxygen. When you put these packs in a sealed container with food, they suck up the oxygen inside. Why is this important? Well, oxygen is like the enemy of long - term food storage. It can cause food to go bad, lose its flavor, and even develop mold. By removing oxygen, oxygen packs help keep your food fresh for a much longer time.
Now, onto the big question: Can you use oxygen packs with plastic containers? The short answer is yes, in most cases. But there are a few things you need to keep in mind.
Compatibility of Plastic Containers
Not all plastic containers are created equal. There are different types of plastics out there, and some are better suited for use with oxygen packs than others.
- High - Density Polyethylene (HDPE): This is a great choice. HDPE is a strong, durable plastic that's resistant to moisture and oxygen. It's commonly used in things like food storage bins and large containers. When you use oxygen packs in an HDPE container, the pack can do its job effectively because the plastic doesn't let much oxygen in from the outside. For example, if you're storing dry goods like rice or beans, an HDPE container with an oxygen pack can keep them fresh for months or even years.
- Polypropylene (PP): Another good option. PP is heat - resistant and has good barrier properties against oxygen. It's often used in microwave - safe food containers and some types of food packaging. You can use oxygen packs in a PP container without worrying too much about oxygen seeping in. This makes it ideal for storing snacks, cereals, or other dry foods.
- Low - Density Polyethylene (LDPE): LDPE is a bit more flexible than HDPE. It's used in things like plastic bags and some thin - walled containers. While it can work with oxygen packs, it's not as good at keeping oxygen out as HDPE or PP. If you use an LDPE container, make sure it's well - sealed. You might also want to double - bag your food or use a larger oxygen pack to compensate for any potential oxygen leakage.
On the other hand, there are some plastics you should avoid. PVC (Polyvinyl Chloride) is one of them. PVC can release harmful chemicals over time, especially when it's exposed to heat or sunlight. And some types of clear, thin plastics used in disposable food containers may not have good oxygen - barrier properties, so they're not the best choice for long - term food storage with oxygen packs.
Sealing the Plastic Container
Once you've chosen the right plastic container, the next step is to seal it properly. A good seal is crucial because if air can get in, the oxygen pack won't be able to do its job.
- Snap - On Lids: Many plastic containers come with snap - on lids. Make sure the lid fits tightly and there are no gaps around the edges. You can test the seal by pressing down on the lid and listening for any air escaping. If you hear a hissing sound, the seal isn't good enough.
- Zipper - Lock Bags: These are a popular choice for smaller food items. When using a zipper - lock bag with an oxygen pack, press out as much air as possible before zipping it up. You can also use a vacuum sealer to remove even more air and create a better seal.
- Heat - Sealed Bags: Some plastic bags can be heat - sealed. This creates a very tight seal that's great for keeping oxygen out. If you're using heat - sealed bags with oxygen packs, make sure you follow the manufacturer's instructions for sealing.
Types of Oxygen Packs
There are different types of oxygen packs available, and each has its own features.
- Reel Type Oxygen Absorber: This type of oxygen absorber comes on a reel, which makes it easy to cut off the right amount for your container. It's great for commercial use or if you're storing a large amount of food. The reel type absorber can be adjusted to fit different container sizes, so you can use just the right amount of oxygen - absorbing material.
- Yome - Q Fast Reaction Type: As the name suggests, this oxygen pack reacts quickly with oxygen. It's perfect for situations where you need to remove oxygen from a container fast. For example, if you're storing something that spoils easily, like nuts or dried fruits, the Yome - Q Fast Reaction Type can get to work right away and keep your food fresh.
- Yome - U Universal Type: This is a versatile oxygen pack that can be used with a wide range of foods and container sizes. It's a great all - around choice for home food storage. Whether you're storing grains, spices, or dehydrated vegetables, the Yome - U Universal Type can help keep them fresh.
Benefits of Using Oxygen Packs with Plastic Containers
- Extended Shelf Life: By removing oxygen from the container, oxygen packs can significantly extend the shelf life of your food. This means you can buy in bulk and store food for longer periods without worrying about it going bad.
- Preservation of Nutrients: Oxygen can cause the breakdown of vitamins and minerals in food. Using oxygen packs helps preserve these nutrients, so you're getting the most out of your stored food.
- Reduced Risk of Mold and Bacteria: Without oxygen, mold and bacteria have a harder time growing. This reduces the risk of your food spoiling and keeps it safe to eat.
How to Use Oxygen Packs with Plastic Containers
- Choose the Right Size Oxygen Pack: The size of the oxygen pack you need depends on the size of the container and the amount of food you're storing. A general rule of thumb is to use one oxygen pack for every gallon of storage space. But if you're storing something that produces a lot of moisture, like fresh - cut fruits or vegetables, you may need to use a larger pack.
- Place the Oxygen Pack in the Container: Put the oxygen pack in the container with your food. Make sure it's not touching the food directly, especially if the food is wet or moist. You can place the pack in a corner or on top of a layer of dry goods.
- Seal the Container: Once the oxygen pack is in place, seal the container as tightly as possible. Check the seal to make sure there are no gaps or leaks.
