Taxable packing bags supplied along with tax free atta

Packing bags are taxable under GST. Sale of Food grains like Atta, Maida are tax free. A flour Mill buys taxable packing material and tax free wheat. Manufactures Atta, Maida and sells it packed in bags. What should be the treatment of GST. If he does not wish to avail GST credit on bags and sells it along with tax free items without GST niether on Purchase nor on sale.
