You may not know it, but quad seal pouches are popular, particularly if you often purchase retail coffee.

This well-liked style of specialized packaging is intended to stand on its own and has a clean, modular appearance.

It’s an advertising department’s dream with four panels that can contain images and information. The quad bag is also well-liked by customers because of the simplicity with which it can be stored.

Aesthetics and marketing aside, the primary advantages of a quad seal pouch over other types of flexible packaging are its reliability and durability.

In this blog post, we’ll explore the features of a quad seal pouch and how it can benefit your product.

History of a Quad Seal Pouch

The term “quad seal pouch” comes from the fact that these types of packaging pouches have two vertical panels and two gussets that are held together by four vertical seals. They may also stand on their own because of the bottom’s rectangular or square shape.

You may either buy premade quad bags from a film provider to be processed further on a pouch packing machine or produce quad bags in-house at your company using a vertical form fill seal machine. The former option is more cost-effective.

The quad seal bag was designed in the early 1990s as an improvement on the three-sided seal pouch, which was popular at the time. These days,  the quad seal pouch is the standard for many products, including coffee.

Process of Premade Quad Seal Pouches

Choosing the premade option entails loading the premade quad bags into a pouch packaging machine, which will then fill and seal them with your goods.

If you are manufacturing on a big scale, it may be more expensive to purchase premade quad seal bags because of their luxury appearance and the ease with which they can be processed by a packaging machine. 

On the other hand, if you are running a lean operation or are just starting out, premade quad seal bags could save you both time and money.

Quad Seal Pouch on a VFFS Machine

Vertical form fill and seal (VFFS) machines are used by many major businesses to manufacture, fill, and seal quad bags in order to cut down on their operational expenses. The operation is as follows:

The role of flat packaging film, also known as roll stock, is placed into the VFFS machine. The role is long and broad. This roll of film is pulled through the machinery and then directed over a rectangular forming tube, which results in the formation of a quad bag.

A block bottom assembly is used to construct the bottom of the bag, and a horizontal seal bar is used to make the bag’s bottom seal. The bag is given its structured shape by the creation of four vertical seals.

Your product is placed inside the quad bag once the bottom seal has been established, and the package is then given its final horizontal top seal in order to complete the packaging process.

The use of a VFFS machine to make your quad seal bags is a common choice and has many distinct benefits.

When compared to the cost of buying them ready-made, the price per bag is lower, and a VFFS machine is often able to produce them at a quicker rate of speed.

However, becoming your own bagmaker comes with its own set of problems.

The fact that operators need a greater level of technical competence to run the equipment and that there is more possibility for mistakes is at the top of the list of disadvantages.

If you choose the premade approach, your goods will be filled into readymade quad bags, which will then be sealed using a pouch packaging machine.

While premade quad seal bags are convenient to use in a packaging machine and have a professional appearance, they may be expensive to use when production volumes are high.

The process is as follows: The premade bags are placed into the loading area of the packaging machine. Your product is then filled into the bag, and the top of the bag is sealed shut.

The main advantage to using a premade quad seal pouch over other types of pouches is that they can give your product a high-end, luxury appearance. Additionally, they can be processed quickly and easily by a pouch packaging machine.

Advantages and Disadvantages of Quad Seal Bag


Can stand on its own

In contrast to standard pillow bags, the quad seal pouch can stand on its own thanks to its sturdy design, making a significant impression on shoppers at the store.

You do not need to have a special stand or box to hold the pouch up, as is often the case with other types of flexible packaging.

This is a distinct advantage if you are selling a product that is frequently purchased in grocery stores or other retail environments. The consumer will be able to see the product and read its label without having to pick it up off the shelf, making it more likely that they will purchase your product over another.

Sustainable and shifting to greener practices

As the world becomes more conscious of its effect on the environment, many companies are looking for ways to be more sustainable and reduce their carbon footprint. One way to do this is to switch from using virgin materials to using recycled materials in your packaging.

Quad seal pouches can be made from recycled materials. The fact that they can be recycled themselves makes them an even more attractive option for companies looking to go green.

More branding opportunities for businesses

Since quad seal pouch packaging can stand on its own,  there is more surface area available for branding and marketing purposes. You can use a larger font size for your product name or include additional information about your product on the pouch.

This is a great way to make your product stand out on the shelf and attract attention from potential customers.

Accommodates heavier fills

The quad seal pouch is strengthened and sturdy as a result of its four vertical seals; as a result, it is an excellent choice for users with bulk product fills.  If your product is on the heavier side, this type of pouch will be able to accommodate it without any problems.

In addition, the four vertical seals also make the pouch more tamper-resistant, which is an important consideration if you are selling a product that needs to maintain its integrity, such as food or medicines.


More expensive than other types of flexible packaging

The quad seal pouch is more expensive to produce than other bags. Producing quad seal pouches does incur a higher cost than doing it with a bag form that is simpler, such as the pillow pouch.

As a consequence of this, the technology required to automatically package your goods into quad seal bags will also be more expensive.

Needs more technical knowledge

You need operators who have a slightly higher degree of technical knowledge for this operation if you want to manufacture quad seal bags on a VFFS machine internally.

Since these machines have more moving parts and assemblies, it is more likely that mistakes will happen with them. As a consequence, you will need to provide your employees extra training and always have someone on hand who is skilled in operating the devices.

It is possible to lay it flat for heavier fillings

When making bigger and heavier quad bags, it is often necessary for the bag to rest flat in order to maintain its stability. This is because of the weight distribution and design of the bag. 

As a result, fewer panels will be visible for marketing reasons, and the goods will need more shelf space.

Products Best for Quad Seal Pouch

Candy and snacks

Quad seal bags are also used for all sorts of candy and snacks. These pouches can be clear or opaque, depending on the needs of the product inside and the marketing goals of the company.

Many companies will use a clear back panel on their candy and snack bags in order to show off the vibrant colors of the product inside.

Pet food packaging

Because of their resilience and tenacity, quad seal bags are often used for the packaging of pet food. It is common practice to attach a carry handle to the top of the quad bag when the bag will be holding larger contents.

Many modern manufacturers of pet food are now putting a matte finish on the quad bags they sell. This gives the items a more upscale appearance and gives buyers of specialty goods for their pets a sense of satisfaction.

Coffee packaging

Quad seal coffee pouches, which have been a popular option for coffee packaging for a significant portion of the modern era, often have a one-way valve installed in order to maintain the product’s freshness.
