Jaypee Cement has launched their new tamperproof cement bags in Kolkata. These laminated poly-propylene bags are technologically superior to the conventional bags and will address major packaging issues in cement trade that occurs due to change in atmospheric conditions besides quality and quantity related concerns. Jaypee Cement Marketing Advisor AK Jain said, "The bag is tamperproof so it doesn’t absorb moisture and hence the quality of cement will be preserved for longer." "The seeping out of cement is also prevented and hence its environment-friendly," he added. The bag will cost around five rupees extra than the conventional ones. "We have plans to increase our capacity to 36 million tonne from our current capacity of 24 million tonne through installation of several new plants one of which is coming up in a few months in Andhra Pradesh," informed Jain.
