Bubble Wraps Uses. Is Bubblewrap a Good Insulator?

Over the past decades, there has just been one major use for bubble wraps, and that is protecting goods while shipping them. Because many people feel there are no other uses for bubble wraps, they tend to throw them away immediately they receive and unwrap their goods. They feel the job of the bubble wrap is done once the goods have been shipped and delivered.

Nevertheless, you can use bubble wraps for other things. Many DIYers have been exploring the use of bubble wraps, as they use them for different DIY projects. In addition to protecting goods from potential damage when they drop on the ground, bubble wraps have other useful properties. One of the secret properties of this item that many people do not know about is temperature regulation.

Bubble wraps have the ability to regulate temperature, and this can come in handy when trying to repurpose it. Bubble wraps do a good job of keeping things cold. The bubbles (which are closely packed air pockets) act as highly effective insulators. Air is a very poor conductor of heat, which is why the bubbles prevent heat from passing through and, hence, helping to preserve cold things.

Interestingly, this does not work in only one way. Because of their great insulating capacity, bubble wraps can also keep things hot. They are insulators, and they prevent heat from entering or escaping. This means they can preserve the heat of any item. Hence, bubble wraps come in handy when trying to keep something hot or cold.

However, bubble wraps have other great properties that help with temperature regulation. If you want to know how a bubble wrap helps to keep things hot or cold, keep reading. In this guide, you will how bubble wrap serves as an insulator. With this information, you will have more uses for this item that always goes to the trash after it delivers your package to you safely. You will no longer be throwing them away but be keeping them for future use.

Insulation Basics

To know how bubble wraps do their little magic of keeping things cold or hot, you need to know the basics of insulation and how it works. First, you need to understand the fundamentals of heat and how it travels. Heat has three major ways it moves. Heat moves through radiation, convection, and conduction.

Irrespective of the mechanism in which heat is traveling, it usually travels from warmest to coolest. Heat always tries to balance the overall temperature of the space. If it is an item, it would move from the warmest part to the coolest part, ensuring even temperature on the item.

Insulations, on the other hand, helps to reduce the pace at which heat travel. They slow down the movement of heat to keep a cooler location cool for a longer period. Insulators work by absorbing heat and, hence, preventing the heat from getting to the cooler part. Furthermore, insulating materials reflect heat waves, and this helps to regulate temperature. By reflecting the heat waves, the heat cannot get to the cooler location.

This works both ways. If you have a cold item in an insulated space or material, the material will reflect external heatwaves and prevent them from getting into space.

If you have a hot item in the insulated space or material, the material will reflect the heat waves from the item and prevent them from getting out. This is basically how a cooler works. This is why you can store cold drinks in a cooler box and it would remain cold for a long time. You can also store hot food in the cooler box and it would remain hot for a long time.

Several different materials are used in the insulation process. Some of those materials include:

1.    Cellulose Insulators

Cellulose insulators are packed closely together to hinder airflow. These insulators are safe for the environment, thanks to their environmentally friendly properties. Nevertheless, cellulose insulations are not packed so closely that there is no space for air bubbles. Because of how densely packed they are, it is difficult for heat to travel through them.

2.    Spray Foam Insulators

A spray form is another great material used to make an insulator. Spray foam has a chemical reaction that makes them expand when sprayed. When they expand, they will create air pockets, which helps to slow down the movement of heat from one point to another. Spray foam also creates a watertight seal and air seal to further reduce the pace at which heat can travel through the material.

3.    Rigid Foam Insulators

Rigid foam also makes good insulation. They have small air pockets and they are positioned like slabs. Rigid form insulation is highly durable and ideal for unfinished spaces.

Bubble Wraps as an Insulator

Now, let us explore the insulation properties of bubble wrap. As we mentioned earlier, bubble wrap serves as an excellent insulator, which is why it can keep things hot or cold for a long time. You might be wondering how it does this. Why and how does bubble wrap lock out heat and keep things cold or hot. To start with, we will explain how bubble wraps are made.

Bubble wraps are made up of two things – air and plastic. They serve as great insulators because air is a very poor conductor of heat, and they have many air pockets. The poor heat conductivity of air makes it a great insulator. When the air is even lock in tiny spaces such as it is in bubble wrap, it becomes more effective at keeping heat out. When trapped in a small space, the air is static, which means air cannot go in or come out.

Heat can move from one place to another when air molecules bump into themselves and transfer heat energy. In an open space, the air has an unlimited amount of molecules that it can bump into and share energy with while air trapped in a little space has a limited amount of molecules it can crash into to share energy with. This is the mechanism behind bubble wrap. They have air trapped in tiny spaces, which does a great job of holding onto heat instead of allowing it to move from one point to another.

You can also use bubble wraps as a seal to limit or completely stop the flow of air. However, you have to seal and apply it well to achieve a good result. In addition to preventing heat from passing through, bubble wraps can also prevent air from passing through. They work as an insulator by ensuring the heat does not get to where the cold item is. This prevents the heat from traveling in the direction of cold items.

Hence, technically, bubble wrap does not keep the cold in. Instead, it shields the cold item from heat. This means external heat cannot get to the item, not that it has a special power to keep things cold. This is the mechanism of how they help to regulate and control temperature. This same thing applies to when you store a hot item in bubble wrap. The bubble wrap does not have anything to keep the item hot, rather, it prevents the heat from the hot item from escaping into the air. If the external environment is cold, it also prevents it from getting to the hot item, which prevents temperature equilibrium from taking place.

What Can I Use a Bubble Wrap for?

Now that you know some of the amazing properties of bubble wraps, you might be wondering what you can do with your discovery. For decades now, bubble wraps have always ended up in one place – the trash can.
