MAKE PACKAGING WORK BETTER.
Plan and prioritise our work to manufacture and supply packaging at fair value, serve clients responsibly and develop solutions that reduce unnecessary environmental impact.

Experience built through practical problem-solving, long-term manufacturing discipline and continuous investment in corrugated packaging capability.
Sling Flexi Cartons Pvt. Ltd. is a corrugated packaging manufacturer established in 1966.
The company began as a modest 3,000 sq. ft. packaging unit founded by the late Mr. Krishnanath Mahajan. Starting without a business background, he built it through persistence, close attention to manufacturing and a belief that dependable packaging should be accessible at fair value.
In 1997, Sling moved into a 20,000 sq. ft. facility and broadened its production capability. That practical manufacturing culture continues today through two operating plants, a 30,000 sq. ft. second facility and an automatic five-ply board line.
Across generations, the objective has remained clear: understand what must be protected, engineer the right pack and manufacture it consistently.

Three moments that shaped Sling's scale, manufacturing capability and ability to solve more demanding packaging briefs.
