That’s why we here at Precise Bag drafted this FAQ on cooler bags to help people like you in choosing the cooler bags you’ll be using. This guide will be comprehensive as it will contain everything you need to know about cooler bags, particularly when it comes to using it for business.

What Are Cooler Bags?

Cooler bags are insulated bags that are engineered to maintain temperatures inside it by keeping the outer temperature at bay. The main purpose of cooler bags is to be able to keep whatever’s inside it frozen or warm.

The term alone is self-explanatory – you don’t have to overcomplicate it!

NOTE: Some people also refer to it as a thermal bag because of its thermal properties.

How Does a Cooler Bag Work?

Here’s a brief scenario how a cooler bag works.

You have frozen yogurt, or ice-cold beer, and you’re going to travel. In traveling, you don’t have a fridge or a freezer, right? So, what do you do to ensure that you’ll be getting the same temperature? – You put it inside a cooler bag.

Cooler bags work and function properly because of insulation. The insulation inside cooler bags varies from one type of bag to another – some use a combination of foil, Styrofoam, as well as a thin layer of aluminum.

More modern types of cooler bags use vinyl, foil liners, plastic, and other insulating materials to ensure that the produce inside of it will remain fresh – yes, it can also be used for grocery shopping fresh meat.

What Materials Are Used to Manufacture Cooler Bags?

There is a multitude of materials manufacturers and suppliers use to produce cooler bags. The common type, though, would be a combination of foil-like padding, nylon, Styrofoam, and EVA (ethylene vinyl acetate).

Take note that this is only for the inside or the inner layers of the cooler bags. The exterior or outer layers, though, can be made from a wide array of materials, some of which include, but are not limited to:

• Vinyl
• Nylon
• Polyester
• Cotton
• Plastic polymers like PP or polypropylene, EVA or ethylene vinyl acetate, and many more

NOTE: Usually, the exterior or the outer part of cooler bags is a combination of these materials. This is to make sure that they remain strong, durable, and resistant to all light damages they are prone of.

How Long Can Cooler Bags Keep Food Cold?

This question is relevant to the bag you’ll be purchasing. Not all cooler bags are made equally, and it’s unequivocally true that the timings are different.

Generally speaking, though, based on data and from the reviews of manufacturers, the typical timeframe of keeping food and other produce cold inside cooler bags is around 2.5 to 3 hours. This is given the fact that you aren’t traveling under the scorching heat of the sun, and your movement is not that active.

This is only a general overview of the timeframe, though, it’s not 100% foolproof. There are manufacturers that give the guarantee of maintain the temperature inside for 4 to 6 hours.

There’s only one way to see, and that is via testing and checking. You can ask your manufacturer about this, but expect that it wouldn’t last anywhere near soft and hard coolers, which can keep ice for up to a day or two.

Can a Cooler Bag Keep Food Warm?

Yes, you can use a cooler bag to make sure that your food is kept hot and warm, too!

The same physics applies to warm or hot food placed inside the cooler bag. The insulation works its magic as it bounces the radiation, energy, as well as the temperature that the cooler bag is emitting.

Not to mention that no air or temperature is escaping, and at the same time, there’s also nothing that gets inside it.

Do You Need to Put Ice Inside a Cooler Bag?

Yes and no – it’s a bit complicated, let us explain.

There are moments where your travel time is just short, and the consumption time of the produce and things inside the cooler bag will be sooner. For this instance, you wouldn’t need to put ice inside the cooler bag – the temperature and coldness can bounce off and can be distributed.

On the contrary, if you are anticipating a long trip, or if you’re suspecting that the consumption of the products inside will be longer, you can use ice.

What If I Don’t Have Ice?

Don’t panic when you don’t find ice to store inside your cooler bags – there is another alternative! Before placing it inside your cooler bag, wrap the food, bottle, or even the container in newspaper before you place it inside the cooler bag.

What this does is allow the newspaper to become the initial layer of insulation between the product and the bag. This slows down the changing of the temperature of the food or the container.

Small Cooler Bags vs. Big Cooler Bags

The difference between small cooler bags and big cooler bags is the size. That’s what many people like to think of it as. But in reality, that is not how it works fully.

Here’s a table that can help you grasp the idea a bit more.

These are just 4 of the many different properties and factors that distinguish small cooler bags from large cooler bags, and vice versa. There are other things you want to consider or look at, and you will only have a clearer picture of it when you see a small and a large cooler bag in person.

Are Cooler Bags Waterproof?

Yes, cooler bags are waterproof and water-resistant, but not all of them are. You see, the ability of the cooler bags to be waterproof depends on the exterior material, as well as the lining or the sewing process involved.

Waterproof cooler bags would be the cooler bags that are made from a particular type of product, such as polypropylene or PP, viny, or nylon.

Do You Put Cooler Bags in the Freezer?

Yes, you can put your cooler bags in the freezer just so that you’re sure that the contents inside of it would not melt. One thing we always recommend our clients here at Precise Bag is to consider placing their cooler bags inside their freezers at least a day before the trip.

What this will do is help the cooler bag become colder, so that whenever air touches the exterior, it wouldn’t easily go through it, affecting the internals or the insides of the bag.

NOTE: The bag is insulated, but there could be instances where the air could seep into the fabrics of the outer layer.
