The foods I take on a trip tend to create messy waste: empty tins of sardines and anchovies leave an oily mess. On my last trip I packed the waste double-bagged in a couple of oven roasting bags. Worked fine, but aside from being too small, the oven bags are transparent and I found myself looking at the rather unattractive mess within.
What I'd like to find is a smaller version of the plastic trash compactor bag I use as a pack liner. The material is tough and opaque. But I'm open to any suggestions for a tough, opaque bag that won't leak.
