With lifestyles becoming increasingly busy and demand for ready-to-cook meals continuing to rise, the right packaging can make all the difference. Together with a well-known food brand, Greiner Packaging is entering the ready meal market in the United States with its proven K3® cardboard-plastic cup. Microwaveable soups as well as noodles and rice as side dishes will be introduced nationwide by mid-year, all packaged in Greiner’s K3® cardboard-plastic cup.

Meeting Market Demand

The demand for convenient meal options is skyrocketing. According to industry research from Spherical Insights & Consulting, the U.S. ready meal market is projected to reach USD 135.10 billion by 2035, growing at an annual rate of around 5% from 2025 onward1. Consumers are prioritizing time-saving features, with a Global Data survey showing that 84% of Canadians consider time saving options as essential when choosing food products2.

For brands, this growth translates into opportunity, but also into rising expectations. Packaging for ready-to-cook meals must support quick preparation, safe handling and strong shelf impact while aligning with sustainability goals. Greiner Packaging is responding to this demand by offering a packaging concept that is already well-established in other food segments.

Cardboard-Plastic Packaging as the perfect cup for ready-to-cook meals

Greiner’s K3® cardboard-plastic packaging combines the premium look and feel of a paper cup with the functional advantages of a plastic container, without requiring the additional PE coatings typically used for paper cups. The cardboard wrap enables high-quality printing and strong shelf impact, making it ideal for brand communication and differentiation at the point of sale. The thin plastic cup ensures reliable product protection, is suitable for microwave use or hot-water preparation which are all key requirements for instant meal applications.

The K3® cup comes with an integrated Tear Tab, which enables easy and intuitive separation of cardboard and plastic, supporting efficient recycling. At the same time, the inside of the cardboard wrap offers additional space for hidden messages, preparation tips, or recipes, creating an engaging touchpoint that encourages proper separation while extending brand communication beyond the shelf.
