Best Food Storage Bag of 2021
The Ziploc Slider Power Shield proved to be the highest quality and most useful bag for our storage needs. The gallon-sized freezer bag is ideal for storing large quantities of food in the freezer or pantry. In addition to the convenient zip closure system, our review team loved that this bag can stand up without support while being filled. The bottom of the bag has an expandable bottom that creates a flat and stable base; this makes filling the bag convenient and easy to store away in a space-efficient manner. This product is also one of the most consistently well-built bags we reviewed and never sprouted any leaks during our testing.
While we appreciated the ease and security offered by the slide closure, it also proved to be the bag's biggest weakness. In our drop tests, every bag we dropped blew out the zipper on the first or second drop. After filling one to the brim, we had one zipper fail when trying to close the bag. Overall, this is a durable, leak-free bag that is user-friendly and stores well.
The Solimo Multipack comes with both one-gallon freezer bags and 6 ½ in x 5 ⅞ in sandwich bags. These two styles cover a lot of ground and should be more than adequate for most households' storage needs. These generic Amazon options performed just as well or better than many of the name-brand bags we tested. Both passed our submersion test without issue and were significantly more drop-proof than most of the other bags in our fleet.
Both the sandwich and freezer bags have relatively significant issues with quality control, and we found that just about every bag we tested came out of the box out with one or two leaky seams in the top corners. While these holes allowed the liquid to escape the interior, they didn't seem to let anything in when submerged. This made them fine for storing or freezing dry goods but not ideal for storing sauces or other liquids.
The Lunchskins paper sandwich bag is a charming and fun alternative to single-use plastic options. While there are many reusable options on the market, the convenience of a single-use product is hard to beat, especially for kids who have a knack for losing things. While these are best for dry food items like PB and Js, the material was stout enough to deal with small amounts of moisture from sliced apples. The bag has a convenient closure system that is similar to a self-sealing envelope.
When it comes down to it, these bags are not waterproof and will start to disintegrate if they get too wet; this makes their application fairly limited in that you wouldn't want to put juicy sliced fruit or extra drippy sandwiches in them. Unsealing the bag without tearing it can take a little finesse and perhaps requires more patience than the average hungry school kid has. If you plan on eating your food all at once, this isn't a problem, but if you want to save some for later, you might be in trouble. Currently available in apple or shark patterns, these non-plastic bags are sure to be a hit with kids and adults alike.
Ziploc Grip 'N Seal Snack bags stay true to their branding. These small bags fit a single serving of snack food exceptionally well, making them an ideal choice for meal preppers or school lunches. The 6 ½ in x 3 ¼ in size ensures you won't fill them with more than you intend on eating without having to bust out a scale or measuring cup. The reduced volume also makes fitting it into a lunch box easy and space-saving. The size is convenient for freezing individual servings of bouillon or sauce and was the most drop-resistant bag we tested, ensuring you won't have a mess if you fumble one on your way to the freezer.
The size of this bag is pretty limiting, and there is only so much you can do with such a tiny amount of space. When filling our bags with liquids or fine dry goods, we like to flip the tops of our bags inside out to create a lip that keeps the bag open — without needing a second hand to help. This product is too short to do this. When you flip it inside out, you lose almost half of the internal volume. However, if you're looking for a bag to quickly portion out individual servings of snack food, this sturdy bag fits the bill.
The gallon-sized Green'N'Pack Zipper Freezer bags are made from 20% recycled materials and claim to be biodegradable. While they might be biodegradable, the packaging explicitly says they are not designed to be composted; it appears they are still heading to the landfill. It's unclear how eco-friendly they actually are, but regardless, they are a high-quality product that stood up to our testing procedures quite well. It was one of the few products with no seam leakage in any of the bags we tested. The thick plastic isn't prone to tearing, and when folded back, holds itself open for easy filling.
While the bag kept moisture out when it was sealed, actually sealing the top of the bag was quite challenging, especially when the bag was wet or at full capacity. Our testers had to press and squeeze to get these things closed. This is another bag you don't want to drop when it's full of liquid, as every bag we tested exploded out the bottom from one counter height fall. At the end of the day, these thick freezer bags are durable, leak-free, and make a small nod to sustainability.
Ziploc Grip 'N Seal Sandwich bags are the perfect dimensions for separating and storing medium-sized lunch and snack items. Bigger than their "snack" size bag but still not too big to put in a lunch box, these bags are moisture-resistant and easy to seal closed.
The quality of the bags we tested was all over the place. Some had one leaky seam, some had two, and some were entirely leak-free; it was hit or miss. The bags did poorly across the board in our drop tests, as every bag we tested burst out the bottom on their first drop. These bags are ideally suited for packing small to medium prepared food items.
The Ziploc Grip 'N Seal Freezer quart-sized bags are a scaled-down version of their gallon slide closure freezer bags. This version doesn't have a slide closure, but the squeeze zip is easy to use and seals well, even when wet. Though the squeeze closure is slightly less convenient than a zipper, you don't have to worry about the zipper breaking or falling off. The offset tab on the top of the bag makes opening it easier as well. Although not the most important detail, our testers noticed that the bags in the box were packed the neatest of all we tested, which ensured easy dispensing.
This product wasn't free of manufacturing defects, and about half the bags we put through our testing process had leaky seams. These bags were yet another example of containers you shouldn't drop. All the units we tested burst on their first drop. These are nice mid-sized bags that stand up to freezing and regular use well.
The Glad Storage and Freezer quart-sized bags are an affordable alternative to the more premium brands. The reduction in price does seem to come with a slight reduction in quality. With that being said, while they weren't the highest performers in any metric, they weren't too far behind in anything either.
Our biggest gripe with this product is how difficult it was to get the zipper to fully seal. Glad advertises that the zipper turns green when it's fully sealed, but the yellow and blue sides simply need to be close together to change color. It does little to indicate if the bag is actually closed or not. Almost all of the bags we tested came with either one or two leaky top seams. This isn't ideal for long-term food storage in the freezer or for storing liquids. While not the highest performing bags in our fleet, they function well enough to be worth a buy and try at their low price point.
Brown paper bags are almost synonymous with to-go lunches. Easier to deal with than a lunchbox, you don't have to worry about losing or cleaning a simple paper bag. Perfect Stix's version is made from 100% recycled paper and fully recyclable themselves; these bags are the most sustainable option we reviewed.
Made from paper, these bags are significantly less versatile than their plastic counterparts and will liquefy into a pulpy mess when subjected to any severe moisture. These bags, in particular, were a little small for our preference and could just barely accommodate a normal-sized sandwich. The more you pack into these little guys, the more prone they are to tearing, so having a bag with more dead space would be preferable. These paper bags are a sustainable alternative to plastic and work best for dry food items.
The quart-sized Hefty Slider Freezer bags have an expandable bottom that makes a stable base for filling and storing them. Their best feature, however, is their slide zip closure. Not having to fuss or fiddle with the top to ensure you have a secure seal is a huge selling point. This quart-size bag was also fairly drop-resistant. It was one of the only bags equipped with a zipper that didn't immediately explode when dropped.
Much like many of the other bags we tested, these were prone to having leaky corners right from the get-go. The zippers were also hit and miss quality. Some would break quickly just trying to open or close an empty bag. These are convenient storage bags that are perfect for people who hate dealing with squeeze zip closures.
Why You Should Trust Us
Buck Yedor was our lead tester on this project. His attention to detail and experience working in the professional food service industry as a cook make him the ideal candidate for testing all things kitchen-related. Between that and bringing a sack lunch to work every day, Buck has used more than his fair share of food storage bags.
The ideal food storage bag is easy to fill, can withstand serious abuse, and, most importantly, keeps air and moisture away from the contents being stored inside. Throw in the ability to be recycled or composted, and you have a winner. After researching the most popular brands on the market, we independently purchased different types of bags and put them through the wringer to see if any lived up to our ideals.
Analysis and Test Results
At first glance, food storage bags appear to be a fairly standardized product. In reality, their performance and quality are all across the board. It's hard to tell just by looking at a bag how well it will function. Our systemized testing got down into the nitty-gritty of where each bag failed or flourished. We looked at each model's durability, moisture and freezer burn protection, ease of closure, and how easy it was to fill the bags without assistance.
Our durability metric consisted of three subcategories: is it leakproof, tearproof, and drop-proof? To test for leaks, we filled the bags with water to capacity and then squeezed them. Throughout our testing, we came to notice that finding a batch of bags without any leaky seams was more uncommon than not. The disposable nature and low price of these products seem to give manufacturers little incentive to have better quality control.
The Green'N'Pack was the best performer in our squeeze test. None of the bags we tested sprung a single leak, which by the time we finished testing proved to be quite the anomaly. The Ziploc Slider Power Shield was the runner-up. While it didn't leak from any of the seams, the zipper did fail during one test. The worst offenders were both of the Solimo bags. Every bag we tested immediately leaked from one or both of the top seams.
To check how tearproof each bag was, we flipped the top of the bag over itself as if we were going to fill the bag. While most of the bags could do this without issue, some would immediately tear at the seams. All of the Ziploc bags we tested were able to be turned in and out without trouble. The Solimo freezer bag tore when being flipped, and unsurprisingly, the Perfect Stix paper bag tore quite easily if you weren't careful.
Our drop testing was designed to replicate a fall from your typical counter height, about three feet. We filled each bag with water and dropped them from that height. The Solimo bags were surprisingly some of the most drop resistant, and the gallon version was easily the most drop-proof of all the freezer bags. The Ziploc snack-sized and sandwich bags were also high performers. Besides the Solimo freezer bags, all the others typically burst on their first drop.
Moisture/Freezer Burn Protection
The main advantage of using plastic for food storage is that assuming everything is functioning correctly, it is a non-permeable material that keeps its contents safe from air and moisture. To check how well each bag actually did its job, we filled each one with oatmeal and then submerged the bag for 30 minutes. To our surprise, with only one exception, even the bags that came out of the box with leaky seams didn't let any moisture get to our dry oatmeal. One Solimo sandwich bag did let in a little moisture. Other than that one incident, all of the bags performed more or less the same.
We found similar results in our freezer tests. After 24 hours in the freezer, none of our frozen food showed any serious signs of freezer burn. We excluded both of the paper bags from both these tests as well.
Ease of Closure
Getting a proper seal on plastic baggies is not always an easy task. We encountered slide zippers, squeeze zippers, a self-sealing adhesive strip, and a roll-top closure. Partial and leaky seals are the worst, especially when you don't discover the failure until long after the contents have covered your fridge or cupboard. The clear-cut winner was the Ziploc slider freezer bag. The convenience of sliding the top open and closed without having to double-check if the bag sealed was ideal.
The other Ziploc bags featuring Ziploc's version of the standard squeeze zipper all worked pretty well, even when full or wet. The Glad squeeze zipper was a battle to get fully sealed. Once they were sealed, they stayed sealed, but the initial closure was a struggle, especially when wet.
Ease of Use
While "using" a plastic bag might seem like a no-brainer, slight design features made some of the bags much more pleasant to use. A well-designed bag is easy to open and fill without assistance and without spilling. This is largely a function of how well the bags can hold their shape when propped open. The Ziploc Slider Power Shield freezer bag was again our front runner.
The expandable bottom creates a stable base, and when the top is folded back on itself, the opening is large and easy to deal with. The Ziplock snack-sized bag was the most difficult to deal with. The small size makes it so you can't fold back the top, so getting liquids in without making a mess can be challenging.
Whether you're freezing a big batch of your favorite pasta sauce or packing snacks for the kiddos, having a reliable bag will give you peace of mind that whatever you're storing will stay where it belongs — safely contained in the bag. We tested and compared 9 of the best-selling food storage bags being sold in 2021. Our side-by-side comparisons let us determine the best and worst qualities of each. We looked at durability, the protection they offered, the ease of closure, and how easy they were to fill. We hope our systematic and scientific approach will help you determine which food storage bags are right for your household.
