Best answer
Right option is (d) BOPP

Easiest explanation: BOPP (bioriented polypropylene) filmis used as a primary package in biscuits. For higher quality products, duplex OPP or OPP combinations such as OPP/PE, OPP/PET, OPP/PVdC in the appropriate thickness and sealing range are used. It offers effective barrier against gas, odor and light. The plastic polyfilm is used in combination with an inner aluminium layer of approximately 7 microns.
