Swiss packaging firm SIG has developed a new microwaveable carton for hot drinks in an attempt to cater to the growing demand for convenient on-the-go beverage options.

The new carton, known as ‘Heat&Go’, does not contain aluminium and therefore can be conveniently heated up in the microwave at home or the office.

Instead of aluminium foil, the carton features a high-barrier film and a light blocking pigment that protects the product from oxygen ingress, flavour migration, light and water. It is ideally suited for still drinks and low viscosity, sensitive, enhanced juice and liquid dairy beverages.

“Our new high-barrier aseptic carton ‘Heat&Go’ can be heated in the microwave up to 60°C, with a recommended temperature of 50°C.”

According to SIG’s own research in China, around 72% of consumers expressed dissatisfaction with existing heating methods for on-the-go products and called for new methods of fast and convenient heating in tune with their lifestyles.

SIG Global Marketing vice-president Ali Kaylan said: “Our new high-barrier aseptic carton ‘Heat&Go’ can be heated in the microwave up to 60°C, with a recommended temperature of 50°C, by allowing brands and co-packers to launch innovative nutritional hot beverage products into new channels and categories.”
