However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

30+ innovations will shape the packaging industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the packaging industry using innovation intensity models built on over 77,000 patents, there are 30+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, cellulose fiber 3D printing, biodegradable packaging films, and multilayer barrier films are disruptive technologies that are in the early stages of application and should be tracked closely. RFID packaging, anti-counterfeiting bottle caps, and clamshell-type packaging are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are resealable medication vials and synthetic resin containers, which are now well established in the industry.

Innovation S-curve for the packaging industry

Child-resistant blister packing is a key innovation area in packaging

Child-resistant blister packing refers to packaging designs and methods that are specifically designed to be difficult for children to open, providing a level of safety and protection for potentially hazardous substances or products. These packaging solutions typically incorporate mechanisms or features that require manual dexterity, strength, or specific actions to access the contents, making it challenging for young children to open them.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 100+ companies, spanning technology vendors, established packaging companies, and up-and-coming start-ups engaged in the development and application of child-resistant blister packing.
