Backpack Padding Foam: Common Types and How to Choose

If your brand is in the process of designing backpacks, either as merchandise or for employees to wear when working in the field, there are several key issues to consider. Before thinking about the sizes or color schemes, however, you must first pay attention to the topic of backpack padding foam,

It is one of the most commonly overlooked aspects of the entire backpack design but could make all the difference to the comfort, durability, and value that the humble backpack brings. This quick guide will provide the insight needed to guide your decisions, covering all of the following issues.

By the end of this post, you will be ready to make calculated decisions about the right backpack padding foam for your project.

What is Backpack Padding Foam?

The humble backpack is primarily divided into two main categories, which is why you must first make a decision between a simple frameless backsack or a framed knapsack that includes either an internal or external support system. Either way, the backpack padding foam will be one of the most significant features by far.

Backpack padding foam is essentially the padding found on the shoulder straps and the back panel of the bag. In other words, the material used for the parts of the product that actively come into contact with your back and shoulders. 

Therefore, the choice of backpack padding foam is crucial for many reasons. It will influence a range of key attributes that determine whether the bag is a useful product, such as;

  • The comfort of the bag against your skin,
  • How well the backpack supports even weight distribution,
  • How well the backpack padding foam creates breathability.
  • The bag’s manufacturing costs.

The industry is worth over $16 billion in the US alone while millions of people use a rucksack daily. Backpack padding foam has a big impact on a user’s satisfaction with the product, especially when they wear them for long periods. And when you keep your customers or employees happy during their commutes or daily activities, it will bring a wealth of rewards for your organization too.
Backpack padding foam can give the product a far more luxurious vibe and even protect the bag against issues like moisture damage.

 

Common Types of Foams for Backpack Padding

When considering backpack padding foams, the first step to narrowing your search is to consider the difference between open-cell and closed-cell foams. You should not make any decision before confirming whether the fabric foam is an open or closed cell.

Open cell fabric foam structures are, unsurprisingly, made with cells that are purposely left open. They are often seen in self-inflating mattresses, such as those used for camping. They are primarily known for their softness and breathability. This is because the interconnected air chambers allow air to be compressed. Therefore, they offer a comfortable touch but are prone to becoming misshapen or unable to effectively manage the weight of a full backpack. Still, it can be suitable for lighter loads.

Conversely, closed cell fabric foam (also known as Ensolite) uses closed air chambers that are not connected to one another. In addition to resisting compression even when the backpack carries a heavy load, the materials do not encounter the same level of water damage. 

When designing a backpack and looking at different padding options, some of the most common fabric foam choices are; 

  • Ethylene-vinyl acetate foam (EVA) – a closed cell foam fabric.
  • Polyethylene foam (PE) – a closed cell foam fabric.
  • Polyurethane foam (PU) – an open cell foam fabric.
  • Styrene Butadiene Rubber (CR) -usually closed cell foam fabrics.

All main backpack padding foam options have pros and cons. When entering the material selection process, it is important to feel the materials as well as see them. This gives you a chance to check the compression and quickly tell whether it will have the properties required to achieve your desired results.

 

How to Choose the Backpack Padding Foam

Understanding the different backpack padding foam options should allow you to make a calculated decision concerning what you want from the product. Before committing to a decision, though, you must ask several key questions to determine the best solution for your requirements. The following checklist will help;

  • Who is the backpack aimed at and which foam solution is right for them?
  • Where is the backpack most likely to be worn and for how long?
  • How much will the material cost and how will that be reflected in the product price?
  • What is the availability of the intended backpack padding foam material?

A backpack that is used by a schoolchild, for example, will have contrasting attributes than one used by a trekking enthusiast who likes to explore the great outdoors. Whether you intend to sell the product or distribute them to your workforce, though, the right choice of backpack padding foam will significantly enhance the product.
Of course, it is especially important when you have a large run. However, even companies that only plan to manufacture a few dozen backpacks should take note.
