If it's alot of powder required, you may want to consider buying a small tin of formula. Else you can pack into one time use individual pack. Works well for me when I used them for my formula. You can get it from this website. Credible seller. http://tlo.com.sg/collections/baby-one/products/baby-one-milk-powder-bags

Id suggest buying a small tin and pack it along with you. Otherwise what about collecting sample packets. There are a lot of mums selling or giving them away. You can check out the blessing pages on face book. :)
