As the world's population grows, so do the opportunities for powdered infant formula brands that communicate quality, security, integrity and trust. And if you can do that in a cost-effective way, you have a real formula for success.


Babies are born every day.

8.2 billion

Projected global population by 2029


Projected CAGR by 2026

Capture your share of the growth in today’s crowded retail marketplace.

The world’s current population of 7.2 billion is projected to increase by one billion over the next 12 years —reaching 9.6 billion by 2050. With approximately 350,000 babies born each day around the world, the future looks bright for powdered infant formula. In fact, the projected CAGR is expected to reach 10.1% by 2026.

To capture your fair share of this growth in today’s crowded retail marketplace, you need every advantage you can get. That means finding unique ways to visually stand out on the shelf, while also delivering functional benefits to engage consumers and keep them coming back for more. And all the better if you can do all this while maintaining or decreasing your manufacturing costs. Our new PureShield® paper container helps you do all that and more.

Once a challenge. Now an opportunity.

The packaging of powdered infant formula involves the use of Modified Atmosphere Processing Systems (MAPs) that remove oxygen and replace it with inert gases. Oxygen promotes deteriorative reactions in food powders that lead to negative effects like the loss of nutritional quality. Inert gases such as nitrogen or a mixture of nitrogen and CO2 help to extend the formula’s shelf life and prevent spoilage due to oxidation.


Pre-gassing is the process of gas replacement throughout the filling process, beginning prior to filling. Pre-gassing systems are designed to provide product with low and controlled residual oxygen levels to the packaging machines. Sonoco paper containers have been proven to perform in pre-gassing systems for powdered infant formula.


Post-gassing is the process of gas replacement after filling. These systems have very low gas consumption and require highly specialized technology since oxygen is removed directly from the filled package. In its existing structure, the paper container could not be run on a post-gassing system... until now.

The Science Behind the Solution

Now, Sonoco’s PureShield® solution allows you to stand out from the crowd even with a post-gassing system, without the need to invest in new filling equipment. PureShield® combines the product performance of a high-strength paper container with a patented gas channel end designed to allow gas exchange during the filling process, all while withstanding the vacuum pressures of post-gassing filling.

The added benefits of PureShield® include:

  • Runs on existing post-gassing assets
  • No change is required to current batch vacuum-flushing process
  • Capable of maintaining current line speeds
  • No increase of N2 consumption
  • Minimal changes required to conveying and seaming equipment
  • Achieves residual O2 below 2%

A Formula for Success = Personality + Protection + Performance

In today’s competitive environment, three advantages are always better than one, and that’s especially true when it comes to the powdered infant formula market. Your package has to uniquely present your brand, ensure the integrity of your product and deliver performance advantages that enhance your manufacturing and your marketing. PureShield® delivers a winning formula you can count on.



One of the key benefits is the unique retail presentation that captures your brand's personality. With a shelf presence designed to engage, paper containers are proven to be appealing on a supermarket shelf. Your logo can be showcased using high-impact graphics providing full 360 degree visibility. A variety of metallic, matte/gloss, and embossed label finishes are available to heighten your brand’s appeal on shelf. Also, the elimination of reinforcement beads offers improved graphics as compared to a metal can.

The round body and over-cap combination also offers a great deal of functionality for consumers and is easy to hold, easy on the go, easy to store, easy to open and easy to re-close.

  • Easy to open
  • Easy to re-close


The multiple benefits delivered by the paper container are the result of the multiple layers involved in its construction, which begins with the container body plies, made of recycled paper, a variety of internal liner structures for barrier protection and a range of top and bottom closure options, combined with a range of ends and over-caps. In addition to protecting the product inside, our peelable membrane is easy to remove and leaves no sharp edges, thereby protecting your customers, unlike metal cans.
