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
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
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:
