Carton packaging structures

Value-adding structure options to meet diverse consumer demands

Our packs are designed to protect a wide range of beverage products, with innovative packaging structures to deliver even more convenience and performance. And our experienced teams of material scientists are constantly finding new ways to enrich our packaging structure options, in turn broadening your possibilities to even more product categories and use occasions, with longer shelf lives and even better sustainability credentials. 

Over the years, we have successfully introduced a number of unique packaging innovations, such as SIG Heat&Go and our wide-variety of food packaging options, meeting the demands of consumers around the world. Also, we are proud to be leading the industry with our SIG Terra solutions, including high performance packaging materials without aluminum foil, with forest-based polymers or circular polymers (mass-balanced).

Standard structures

Producing aseptic packaging for liquid food and beverages requires complex, multi-layered material compositions that fulfill highest demands in terms of food quality, safety, and more. The main material in our packs is renewable paperboard. To ensure our packs handle different product types – such as milk, juice, and liquid food – this paperboard comes in a range of protective structures featuring thin layers of polyethylene and aluminum.

Our standard: highest quality and safety. The typical material structure for an aseptic carton is a combination of various layers with different raw materials and functions to realize the overall package performance, fulfilling:

  • Product protection (light, oxygen, aroma)
  • Appearance and handling
  • Process capability
  • Transportability
  • Resource efficiency

Food packaging

Explore our food packaging options and related food technologies and choose the optimal solution for your product.

Convenience meets protection

Our aseptic and retortable carton packs are perfect for food products with a high particulate content. This includes everything from soups, sauces, and tomato preparations to pulses, fruit spreads, baby foods, ready meals, desserts, and more. Explore our range of solutions for food!

Choose better

With SIG Terra, our portfolio of packaging innovations with improved environmental performance1 and/or improved circularity, we focus on three main areas: simplified packaging materials without aluminum foil, polymers linked to forest-based or circular materials (mass-balanced).

SIG Heat&Go

Our unique SIG Heat&Go structure enables hot drink concepts based on liquid dairy or dairy alternatives as well as juices and teas, unlocking a wide variety of new and exciting hot drink products.

Microwavable packaging

To meet the growing hot drinks trend, we developed our unique SIG Heat&Go solution. The aluminum foil found inside our standard carton structure was replaced by a high-barrier alternative that allows drinks to be microwaved together with the carton pack without compromising product quality.
