Criteria for Evaluation

The Storage Capabilities It Possesses, Interior and Exterior

Simply, what good is a lunch box that does not have enough storage to satisfy your needs? Do not strain yourself too hard on that question, as there is not one. If this aspect of the lunch box is below your desires, then you should look elsewhere. This is how important proper storage is, whether a lot or a little. But, storage comes in many ways; such as in the interior and exterior.

First, ask yourself when you are planning on using your future lunch box. Is it going to strictly be for your lunch at work? Do you plan on taking it on family vacations and accommodating for multiple people? The answers to these types of questions will have direct implications on the storage you will need. Once you have got a general idea on when and where you will use it, you can start analyzing the storage.

As you noticed, most of the entries on this list included several extra pockets for additional drinks and accessories. Outside pockets can hold key essentials such as snacks, water bottles, keys, smartphones, and wallets. Interior pockets can then hold foods that you do not want to become accidentally soggy. But, the interior still must remain spacious enough for your cold food items.

The reason exterior and additional pockets can come in handy is that you do not want to mix everything you possess in the interior. Outside pockets keep your accessories and snacks within arm’s reach and also prevent them from getting too cold inside. But, inside pockets are just as important as you will want to keep your cold and warm contents separated inside.

How Adequately It Will Keep the Contents Inside Insulated

Storage may be the single most important criterion in the process of deciding which lunch box you want. But, do not sleep for one second on the design of the insulation because this can be just as critically important. If you never plan on packing cold or hot contents (that need to remain so), insulation will never become an issue for you. It is hard to imagine, though, that you would never want to take refrigerated items along with you on your trip.

Without proper insulation, even with ice inside, the cold air will escape and your cold food items will begin to increase in temperature. After all, on scorching hot days ice will not take long to melt and transform into water. Thankfully, when it comes to insulation, there is not one set solution that you need to look out for. Various types of lunch boxes will have different types of insulation, so there is no need to concern yourself with finding one with a specific type.

On this list, specifically, there were a plethora of insulation designs. A few, in particular, were PEVA-lining insulation, neoprene insulation, PE-foam insulation, and food-grade aluminum foil. All of them will more than suffice, but the aluminum foil design is quite ingenious. Aluminum foil, combined with some other sort of foam insulation, will both conceal the temperature and keep your foods fresh for several hours. Think about when you store away food in your refrigerator, often times you probably end up wrapping it in aluminum foil.

If It Is Easy to Transport Around and to Use

The entire concept around a lunch box is to give people a means to store food/drinks away for their upcoming trip or event. While it is not against the imaginary rules, they can be used in the comfort of your home, as well. But, that seems a little pointless. Around 99 percent of the time, they are going to be used to transport food from one location to another one. During this process, it is helpful when the lunch box/bag is extremely portable. Almost every single bag will come with an adequate way to achieve this, so you do not have to stress too much about this.

Typically, they will come with either a solo-handle or dual handles on the top. Usually, the grips on the handles are constructed from some sort of leather or likewise material; ensuring a comfortable grip. The one extra feature you can keep your eyes on, that not all possess, though, is the adjustable and detachable shoulder strap. In times where you have a heavy load and your hand is growing weak from carrying it around, it is convenient to be able to take the strap and carry it over your shoulder for a while. Even with a light amount of contents inside, the ability to use multiple carrying options is a huge bonus.

Now, as far as the ease of use, the major aspect you need to pay attention to is the zipper design. Even a toddler could figure out how to operate and open a lunch box, but a poor zipper can complicate matters exponentially. This is not necessarily a deal breaker, as many top models sometimes experience an issue with the zipper catching on the lining, and as long as it operates smoothly a majority of the time it should be fine. If it happens frequently, then you may want to look elsewhere.

The Overall Dimensions of the Lunch Box and If They Will Suffice

In a way, this is almost piggybacking off two of the previous three criteria. So, it may not seem necessary to devote a separate section for it. But, it is hard to think of a consumer product where the official dimensions of it do not play an important role in the decision process. At least, a product in which the dimensions are subjective to change from brand to brand. For most lunch boxes, the dimensions that are measured and documented are height/depth, width and length. Depending on the manufacturer, they may have it listed differently in their product description.

All these measurements play an important role as they will determine if you can stack multiple Tupperware on top of one another, store drinks upright and not on their side, or store extremely long containers inside. Once again, it is all in the thought process. If you know for a fact you are going to need the box to accommodate for multiple containers and fully-sized drinks, aim for a greater height and wider surface.

An important note to mention, however, and one you may fall victim to, is most manufacturers will list the dimensions of the entire bag. This means that the top, thick sides, and bottom will add inches to the total measurements. Thus, the interior dimensions will most likely end up being a little smaller than you actually think. Give yourself a little room for error if you intend to measure the containers and/or drinks that you plan on storing in the lunch box (a few inches or so).

The Other Design Choices and Extra Features That Were Implemented

The main design features of the storage and interior insulation have already been covered in-depth, but there are still a plethora of other design choices and features that can sway your decision. For starters, how about the overall design of the lunch box? On any given trip, you can never predict what is going to happen. Contents can spill inside, debris and dirt can find their way on it, and accidental tears can happen. So, why not have a lunch box that manages to be prepared for all of it?

With bags that are leak-resistant and water-resistant, when contents spill inside (or ice starts to melt) the excess liquid will not escape the bag. However, what about the inside? This is where models with a stain-resistant material are so effective, as accidental spills will not leave unattractive stains. Then, there are the versions that are resistant to tears and dirt; which ensure the pack remains undamaged. Much like a smartphone case that claims to be shatterproof, as long as you do not intentionally attempt to puncture and tear the lunch boxes that have this design feature they will hold up against accidental instances (depending on how severe it is).

Finally, there are the models that are dishwasher and freezer safe. Reasons to why you may feel the need to store your lunch box in the freezer are entirely up to you. But, in the instances where it would lead a lending hand, it is nice to have. The benefits of being dishwasher safe, or easy to clean with a damp cloth, go without saying as eventually, you will need to give the lunch box a proper cleaning.

Other Noteworthy Aspects to Pay a Good Mind To

The situation might present itself that you simply can’t decide on a few different models. They may be so equal in price, quality, design, and features that you feel the need to resort to flipping a coin. Well, do not fret, as there are still a few other aspects you can pay attention to that may end up swaying your final decision. All of which is not solely exclusive to lunch boxes, but are still important in their own right.

Firstly, see what kind of warranty or money-back guarantee is promised, if any. As you may have noticed, there were quite a few models on this list that offered some sort of money-back guarantee. Some with your standard 30-day money-back guarantees, while others offered a lifetime warranty if any problems arose in the future. Much like any product in the world, this is something you take a chance with. So, if you fall in love with a particular lunch box and it does not have a warranty, it should not affect your decision. Just think of this as an added bonus but not an essential commodity.

Next, perhaps some versions where the manufacturer offers several different sizes, design and color options are important to you. Even if the deciding factor is as simple as preferring the color and design of one model over the other, so be it as there is nothing wrong with that. But, maybe the size of the bag is the only aspect stalling your decision. If there are more size options available, perhaps there is another one that better suits your needs.

Finally, it is never a bad idea to prioritize brands that offer additional accessories and products. It depends on the seller, but they may offer Tupperware, water bottles or ice packs. Clearly, the most important aspect in your final decision is the overall quality of the lunch box but extra accessories never hurt!

FAQs

Q:  Will They Keep Hot Food Warm and How to Do So?

A:  Typically, lunch boxes are associated with food items that are either dry or meant to be kept cool. But, the insulation that is present in them, will also allow you to store hot meals inside of them. Just know, it will be a little harder to maintain than colder food will. To start, right before you place your meal into the lunch box, either microwave it or place it in the oven to raise the temperature. Then, wrap it with aluminum foil and then place it inside the lunch box. If you plan on leaving the contents in there for several hours, it may not be scorching hot but it should still be warm.

Of course, you also need to remember you may not be able to keep cold contents with warm ones. If you have any sort of ice inside, it will be twice as difficult to store hot foods. Your best bet is to avoid as many hot meals as possible, although if you devote your pack to it, you would be fine.

Q: How Do You Clean a Lunch Box?

A:  Some lunch boxes will be perfectly washer or dishwasher-safe. But, for the ones that are not, you are going to need to hand wash them. Thankfully, this is a very easy process and you eliminate any chance of damaging the material via machine-washing. Firstly, fill your sink with warm water and add a small amount of detergent inside. If the lunch box is waterproof, which will vary from model to model, go ahead and completely submerge it in the soapy water.

Then, it is time to get your hands dirty and unleash some elbow grease. Simply scrub the interior and the exterior of the lunch box with a soft cloth. If you can’t submerge it underwater, be sure to wring the cloth out before using it so no excess water gets inside. To rinse it, wipe it off with another cloth filled with regular water. To cap it off, hand-dry it with a towel and then allow it to air-dry until it is completely dry.

Outside of being handy for instances where accidental water is spilled, a waterproof lunch box also makes cleaning them immensely easier.

Q: What to Pack for a Healthy Lunch?

A:  While this question has nothing to do with the lunch boxes themselves, it is a pretty common one that gets addressed. Since you were a kid, chances are, your parents beat into you how to eat and pack healthy. But, maybe they did not or you have forgotten after all these years. No matter where you plan on using a lunch box, packing a nutritious meal is always a smart choice. Here is a strong way to achieve it:

Firstly, and not surprisingly, be sure to include a various amount of fruits and vegetables. Secondly, include the main portion of the meal (probably a peanut butter and jelly sandwich or some slices of lean meat). Then, you could pack a snack of cold cheese and crackers. Lastly, be sure to pack a large container filled with ice water. Most of the lunch is entirely up to you as you can choose the types of fruits, vegetables, and meats. For a healthy meal, that does not sound too bad, does it?

Q: Can You Fill Them with Ice?

A:  At first glance, this seems like a rhetorical question as how else would you keep your contents chilled? But, when you dive a little deeper, you may get an answer you were not expecting. If you plan on placing unpacked ice inside of your lunch box, you need to be aware of a few factors. One, if the bag is not waterproof or leak proof you risk damaging the material with excess water. The insulation will adequately hold the ice, but it will not prevent it from eventually melting.

Also, if the bag is waterproof, do you really want all the food items inside floating in the water and possibly becoming soggy? So, the answer to the question, “Can you fill them with ice”, is a yes (if it the lunch box is both leakproof and waterproof. But, it is not recommended to do so. As an alternative, consider freezing a couple water bottles or placing multiple ice packs inside. This way, when the ice packs and water bottles begin to thaw, there will not be buckets of water inside.

Q: How Well Will They Hold up In Scorching Temperatures?

A:  This is a question that will have varying answers as it all depends on each particular model. The more insulation that is present, the better chance the included food items will stay cold. There is nothing you can do to change that, which makes insulation immensely important. But, on scorching hot days, there are a few tips that you can follow to extend the amount of time they will stay chilled.

Be sure to open and close the bag as little as possible as each time you do so, precious cold air is escaping. In addition, make sure that you have loaded it with ice and that it is completely frozen (the ice). Lastly, if you can, ensure that you do not set it directly in the rays of the sun. If possible, place it in a shaded area as direct heat from the sun will rapidly increase the temperature. On certain days, your food may be impossible to keep cold but if you keep these tips in mind it should hold up on most days.

Q: Will the Insulation Alone Keep the Food Items Cold?

A:  Insulation is kind of a funny concept in that it still needs other resources to properly perform the job it was designed for. In other words, insulation is designed to keep whatever is inside it insulated from the outside world; while not letting any air escape. But, alone, it does not work as a cooling or heating method. Thus, you still need to place either ice packs, frozen water bottles, or ice inside to keep the items chilled. All the insulation is going to do is trap the cold air inside, but it will not create the cold air.

Now, do not feel stupid if you thought that the insulation alone would keep your contents cold. But, now you do not have to fall into the trap of believing this.

Final Thoughts

It is official, you now have all the information and knowledge you will need to make an accurate decision for your new lunch box. As this can be a lot of information to soak in in one sitting, be sure to think it over for the next several hours. Instead of looking at it through a broad lens, focus on the aspects and features that you cherish the most. Rank the lunch boxes based on this criterion and then the other features will speak for themselves. Plus, with some of the manufacturers offering money-back guarantees, you could always return them if you are dissatisfied with your purchase. But, if you stick with any of the ten on this list, the chances of that happening are very slim!
