So I've made lids, they have the 1/4" hole in the middle of them. I tried allll over the place to look for tyvek envelopes but I couldn't find any at my post office and the ones at my office supply store are in packs of 50, so they are somewhat expensive. So instead, I used micropore tape, to cover the hole and then I marked it with a sharpie and covered the micropore tape with a big dab of clear silicon. Should I be okay with this setup? Should I try to find tyvek envelopes? I do have some envelopes that are like lined in bubble wrap, will those work?
THINGS YOU NEED -JAR LIDS ANY SIZE WILL WORK -SCREW DRIVER OR NAIL -HAMMER -TYVEK(there free at your local post office) -RTV HIGH TEMP SILICONE -RAZOR KNIFE -PEN OR A PENCIL(OPTIONAL) -MAKING THE HOLES grab your hammer, screw driver(or nail), and jar with the lid on........ also make sure your center.... like so then make the holes and dont pound on the lids like you would nailing somthing to the wall youll break the jar.......it dont take that much stregnth to puncture the lids -MAKING THE TYVEK now grab the razor, the lid, and pen or pencil(optional)you can trace the lid with the pencil thn cut it out or you can just cut around the lid watever you thinks easier check it out thn grab the RTV SILICONE take the cut out of the tyvek and dab some silicone on..... again make sure your center like this NOTE: watever side you punctured will leave a bur like this now that side needs to be faced down like this NOT LIKE THIS it doesnt matter if you punctured the top or the bottom of the lids either....... they work both ways the reason why the burr needs to be facing down is because the tyvek will be sticking up and wont seal as well and will also allow for a higher rate of contamination in my experience so i always do it this way, now put the lids on first then the tyvek and seal that bitch LET IT DRY 24 HOURS BEFORE USE YOU CAN ALSO REUSE THEESE MULTIPLE TIMES IVE DONE IT................. AND YOUR DONE AS SIMPLE AS THAT -HERES THE END RESULTS
Tyvek - is a brand of flashspun high-density polyethylene fibers, a synthetic material; the name is a registered trademark of DuPont. The material is very strong; it is difficult to tear but can easily be cut with scissors or a knife. Water vapor can pass through Tyvek (highly breathable), but not liquid water, so the material lends itself to a variety of applications: envelopes, car covers, air and water intrusion barriers (housewrap) under house siding, labels, wristbands, mycology, and graphics. Tyvek is sometimes erroneously referred to as "Tyvex." EDIT : There was another thread in regards to the same topic(On another OMC), although I never knew about it, I just went over it and found a piece of info that may be of use to some...this PDF can be found simply by searching google levels_of_protection.pdf History Tyvek is a nonwoven product consisting of spunbond olefin fiber. It was first discovered in 1955 by DuPont researcher Jim White who saw polyethylene fluff coming out of a pipe in a DuPont experimental lab. It was trademarked in 1965 and was first introduced for commercial purposes in April 1967. According to DuPont's website, the fibers are 0.5–10 µm (compared to 75 µm for a human hair). The nondirectional fibers (plexifilaments) are first spun and then bonded together by heat and pressure, without binders. Tyvek is manufactured at the Spruance plant in Richmond, Virginia, and in Contern/Luxembourg. Properties Among Tyvek's properties are: [*]Light weight [*]Class A flammability rating. [*]Chemical resistance [*]Dimensional stability [*]Opacity [*]Neutral pH [*]Tear resistant Uses Large sheets of Tyvek are frequently used as "house wrap," to provide a water barrier between the outer cladding of a structure and the frame, insulation, etc., allowing water vapor to pass yet restricting air infiltration. Tyvek is used by the United States Postal Service for some of its Priority Mail and Express Mail envelopes. New Zealand used it for its driver's licenses from 1986 to 1999, and Costa Rica, the Isle of Man, and Haiti have made banknotes from it. These banknotes are no longer in circulation and have become collectors' items. Tyvek coveralls are one-piece garments made of Tyvek, usually white in color. They are often worn by mechanics over their clothes to avoid contact with oil and fuel. They can also be worn for painting to protect skin and clothes from splattered paint, for installation of fiberglass insulation, by workers in laboratories and cleanrooms, and for any other use where a disposable, one-time use coverall is needed. Tyvek coveralls are also used for some light hazardous materials applications, such as asbestos and radiation work but do not provide the level of protection of a full hazmat suit. Tychem is a sub-brand of Tyvek rated for a higher level of liquid protection, especially from chemicals. DuPont makes Tyvek clothing in different styles from laboratory coats and aprons to complete head-to-toe coveralls with hoods and booties. In 1976, fashion house Fiorucci made an entire collection out of Tyvek. More recently fashion retailer and manufacturer American Apparel has included white Tyvek shorts as part of its range. Rock band Devo is known for wearing large, two-piece Tyvek suits with black elastic belts and 3-D glasses. In 1979 Devo appeared with Tyvek leisure suits and shirts made specifically for the band, with the band's own designs and images. In 2005 Dynomighty Design introduced a Tyvek wallet made from a single sheet of Tyvek. Increasingly, reused Tyvek material is being used by home crafters. Protective sleeves for Compact Discs and DVDs, tote bags, and origami wallets  also use Tyvek-containing materials. Tyvek is also used as a durable fabric in shoes. The shoe brand Unstitched Utilities pioneered Tyvek's use in its line of footwear. Tyvek is a strong, waterproof cover that serves various purposes. One example from sporting goods is its use in archery. This is due to its waterproof properties. Tyvek is used to construct target faces, replacing paper faces which are easily damaged when wet. Recycling Though Tyvek superficially resembles paper (for example, it can be written and printed on), it is plastic, and it cannot be recycled with paper. Despite the fact that some Tyvek products are marked with the #2 resin-code for HDPE, it is not usually collected with plastic bottles as part of municipal curbside recycling programs. Instead, DuPont runs a program in the United States where disposable clothing, coveralls, lab coats, and other Tyvek disposable garments can be recycled, as well as providing a mail-in recycling program for envelopes. EDIT 2 : I am currently awating an email from another member at a different OMC With test results On the "flashspun high-density polyethylene fibers""Tyvek Envelopes"...its very good results, Try not to handle your Tyvek envelopes too much...You'll see why once I get the Ok to post the info from him I would Like to throw out a Big Thankyou to Zero for the information Provided Below The Information here was achieved by a simple google search, but weve all answered this question 100s of times...so now its a simple answer...link to this and let others who need the info read Peace **D**
