Doypack Packaging

August 23, 2022

Doypack packaging is a flexible packaging option that has grown in popularity in recent years.

This type of packaging is made of a thin, flexible plastic film, aluminum, and other laminated materials that can be sealed at the top. It is often used for food products and is a good choice for products that need to be kept refrigerated or frozen. Doypack packaging can also be customized to fit your product’s needs and is easy to use.

This packaging also has features and benefits that make it an attractive packaging option for many products.

In this blog, we will discuss what doypack packaging is, its features and benefits, and how to use it.

What is Doypack Packaging?

Doypack Packaging

Doypacks are a kind of flexible packaging that can stand upright on its own. 

The product, which is often referred to as a pouch, has a bottom that is securely sealed to ensure that it will not tip over. If you need a way to show your bulk or loose goods in a more organized fashion, look no further than this product.

This type of packaging is made from a thin, flexible plastic film. It can be sealed at the top using an easy-open tear notch. Once the product is sealed, it can be stored in a cool, dry place.

An Overview of the Doypack Bag’s History

Doypack is a registered trademark across the world for the Thimmonnier Doy type bag that was created in 1963 by French inventor and Thimmonnier Company president Louis Doyen. Thimmonnier states that annual sales of Doypack pouches have risen to almost $40 billion.

Doyens are folded into a ‘W’ shape at the bottom after two flat sheets have been glued together along their sides.

Once the pouch is full, the “W” expands to provide a stable basis for the contents. This breakthrough pouch style may now be found everywhere under the name “stand-up pouch” due to its unique ability to maintain its upright position.

According to Packaging Digest, a subsequent version of the stand-up pouch was created by Taiwanese engineer Wayne Chang, who used a tube as the body and sealed not one but two gussets which are located at the top and at the bottom.

Unlike many other stand-up Doypack bags, which tend to tip over when just partially full, this bag type may keep its stability even when empty.

The S-Pouch, or Double Doypack bag as it is more often known, is a kind of bag with a unique shape with a double-sided zipper.

Compared to a standard stand-up pouch, Chang says it can be filled to 97% capacity, resulting in a 20% decrease in pouch size and a corresponding reduction in the amount of material needed.

Features and Benefits of the Doypack bag

Some of the features and benefits of doypack packaging include:

Can stand upright

One of the major features of doypack packaging is that it can stand upright. This is because the bottom of the pouch is sealed. You do not have to worry about your product tipping over and spilling.

Can be customized

Doypack packaging can be customized to fit the needs of your goods. You can choose the size, shape, and color of your pouch. You can also add a zipper or other closure to keep your product fresh.


Doypack packaging is flexible, which makes it easy to store and transport. You can pack more products in a smaller space because the pouches can be squeezed into tight spaces.

Application Trends in the Packaging Industry for the Doypack Bag

Liquid packaging

In the past, liquid goods such as soups and sauces were packed in rigid containers such as glass bottles and metal cans.

However, transporting and storing rigid packing forms is more complex and costly, and they provide additional safety risks due to the presence of shattered glass and sharp metal edges.

When it comes to dispensing liquid items, modern stand-up pouches are typically safer than flexible packaging methods of the past and include fitments such as pour spouts that make the process far simpler. 

Moreover, doypack packaging methods have been increasingly used for applications such as condiments, salad dressings, and edible oils.

Food packaging

Snacks must be packaged in appropriate-sized containers that are light and portable, and that can be resealed and enjoyed later.

Even after the product has been removed from its packaging and resealed, the Doypack bag maintains its effectiveness as an excellent barrier against rotting. This is true even in the event that the package has been opened.

In addition, in a market that is very competitive, snack packaging that sticks out is more likely to attract the attention (and the money) of a busy customer.

Doypack packaging is also effective in marketing as it doesn’t have to be stacked with other items to stand. 

Pet food

The enormous bulk paper-walled sacks of kibble are a thing of the past as pet owners progressively seek out fresher and gourmet meals for their pets.

The use of flexible packaging solutions creates a stronger barrier against humidity, pollutants, and pests, which in turn extends the shelf life of the product.

Pet food doypacks and treats are becoming smaller and sometimes formed in unique ways, which is giving an appealing and simple option for customers to sample new product variants. 

Plus, daypack packaging is increasingly being used for portion control and single-serve meals.

Legal marijuana

As cannabis legalization spreads throughout the United States and Canada, the industry is becoming increasingly sophisticated to keep up with demand.

The company wants to make people feel better about trying the product, even though it has a bad reputation.

In order to achieve this, they are, for example, updating the look of their once-popular “transparent plastic baggie” packaging. Doypack bags are often used because of their high quality and widespread recognition.

Now that doypack packaging is being used for more and more products, it is important to be aware of the benefits that this type of packaging can offer your business.

Doypack Pouch Packing Machines

Doypacks are quickly becoming one of the most popular designs of bags available today.

Therefore, there is a wide variety of equipment available on the market, such as form fill seal equipment and premade pouch packing machines, that may automate the packaging of this particular kind of bag.

Currently, consumer packaged goods (CPG) firms who are looking to give their products a more upscale and specialized appearance are ordering premade Doypacks and then investing in automated pouch packing technology to finish the packaging process.

These machines are easy to set up and use, can quickly adapt to different pouch sizes, and produce a finished product that looks and works better.

While doypack packaging is not a new concept, the ability to package this type of pouch using automated machinery is. 

And, as the packaging industry continues to move towards higher levels of automation, it is likely that the doypack will become one of the most popular pouch types on the market.
