I just wanted to let you guys in on a hot tip I first learned about from a guide for pressing dry sift from the seventies: Grocery bag plastic doesnt stick to hash or oil. At all. Even moreso than silicone. In the guide, it suggested using grocery bags to hold dry sift in while you heat and press it into bricks of hash, but I have found that it works just as well with oil.
Why is this better than silicone? Well, I notice that my oil, when stored in those silicone balls made for storing hash, very quickly smell (And taste) like plastic. This happens in any silicone product, even in my lab grade silicone containers. The problem is the mesh of the polymer is so thick that solvents used in its manufacture get trapped inside. Normally this is no concern, but if you put a lipid against silicone, it acts like a poor solvent, and gradually pulls contaminants out of the silicone. The grocery bag, however, is incredibly thin, and doesnt hold on to these solvents at all. To be extra sure, you can immerse your bag in liquid butane or in iso briefly, then dry. These very good solvents will quickly pull out any residual baddies, though honestly by the time a bag gets to you its thoroughly aired out and safe.
The best bags are the tan kind, not the white, as the white has dyes which may leach. Only use portions of the bag that have no printing and are the undyed tan. You can cut 1' squares out of most bags; I use it as a dish liner for BHO extraction and curing, instead of parchment or wax in vacuum purges, and most conveniently, to tie up bags of oil. I find this simpler than vials, which require much poking and heating, whereas a small wad of oil wrapped up in plastic is easily accessable. While the oil can begin to stick in hot temps (80 plus), just like with silicone, a quick pop in the freezer remedies this. I have successfully stored BHO for a year plus in this material with no change of taste in the oil and no change in the physical characteristics of the plastic. With silicone, even if I try to purge it in butane first to get rid of the chemicals, makes it about 2-3 days of storage before the plastic smell sets in. Its obviously no replacement for storage vials but its easier to use when you are frequently dosing.
