Uflex – Resource optimised packaging for Indian staples

INDIA • Uflex is developing solutions to extend the use of flexible packaging, creating resource-optimised packaging for essential staples such as pulses, wheat flour, sugar, salt, and oil.

Talking more about this initiative, Uflex Limited joint president of packaging and new product development Mr Jeevaraj Pillai said: “The flexible packaging sector in India will get the real boost when high-volume (bulk) commodity food items like pulses, wheat-flour, sugar, salt and aoil are marketed in packaged form. In India, almost 80%-85% of unbranded food products are still sold loose without pre-designated packaging. We have recently developed a 2-ply laminated packaging for wheat flour comprising a specialised polyester (PET)/specialised polyethylene (PE) structure.”


“Therefore to ensure that the wheat-flour packaging is sturdy enough with good mechanical properties to withstand the weight of the product being packed as well as to sustain the rough supply chain conditions, we adopted a three-pronged approach. We modified both the polyester film and the sealant PE Layer to optimise the overall characteristics of the packaging. Both the layers were rendered special high dart impact resistant. We were able to reduce the thickness of the PE by almost 38% which substantively downgauged the overall packaging. This reduction makes the packaging light-weight/resource optimised and far more sustainable than its erstwhile version.”

“The third and the most important modification has been registered nano-perforation on the laminate. The nano-perforation helps to dispel the air while filling the flour inside the pack and also ensures that no infestation by mites and other micro-organisms takes place resulting in spoilage of the wheat-flour packed inside. In fact, the perforations are designed just enough for removing the air and restricting the passage of mites. Further, the nano-perforation on the pack also imparts anti-skid properties to the bag paving way for easy stacking all through the supply chain.”
