    Extending the useable life of one-way bags

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I dont know if its just me, but 500g gusseted valve bags dont seem to last more than a couple of uses. I find that the resealable strips come adrift from the bag rather than just opening. Maybe Im just too eager to get at the contents first thing in the morning. Not such a problem with the smaller bags - less resealable strip, I suspect.

    Here is my solution. Im sure there are others. I got two large bag clips and made them into one very large bag clip.

    cheers

    A bag resumes useful service.

    Excellent.
    Australian ingenuity. Reuse like this also reduces waste in the rubbish tips as well as saving money for more coffee beans.
    Well done.

    I have seen them (in various sizes) sold at Ikea, but there must be other places that have them.

    Hi Mal,

    these ones came from a $2-style variety shop (10 assorted sizes for ..$2) but you can get them at IKEA http://www.ikea.com/au/en/catalog/products/70083252
    or even Ebay, although the postage is a bit of a shame

    Re: Extending the useable life of one-way bags

    great ingenuity, but from memory there was a thread here a while back regarding re-using one way valve bags - i think the outcome was basically to ensure a VERY thorough cleaning b/w uses to try to rid old rancid oils from upsetting the new bean batch.

    Yeah I picked up a spray bottle of Isopropyl Alcohol from Bunnings to fix that ;)

    And the Impulse sealer does the rest. I managed to get almost 5 seals out of one bag, Im sure I could go tighter though.

    ajay, thats a great little mod youve down there. Im eyeing off the ones keeping my bag of chips fresh now haha.

    I line my valved bags with cheap freezer bags.
    No need to clean ever.
    Just toss out the old freezer bag and line with another.

    Does my bag look dirty? I dont think it does :-?. *As you mentioned, there was another thread about cleaning bags. http://coffeesnobs.com.au/YaBB.pl?num=1198287865/12#12

    This one is about sealing them.

    Re: Extending the useable life of one-way bags

    Ajay & TG have the answer,
    i will have to find somewhere close to purchase them as a 80km round trip to Ikea just doesnt seem worth it.

    No because the oils would then dirty the valved bag.

    They cost less than 0.01c each.

    You might be able to melt them and fuse the plastic, but I used a new Selleys product that they call Plastics Glue. It is two parts, consisting of a primer in a texta-style pen which you apply to both surfaces, then a tube of super-type glue which is applied to one surface. Grabs and holds very quickly.

    Yup, it sure does :o

    I managed to stick my index finger to my roomba with this stuff. If not for having the nail polish on hand I mightve had to make a gruesome decision.

    Skin off finger vs beloved robot vacuum? Hmmm....

    Its been an interesting week :-/

    PS. Great tip on the clips ajay -- off to Aldi we go :D

    Re: Extending the useable life of one-way bags

    Ive been using the freezer bags inside the seable bags for a while now thanks to TG :)

    Question to those who use this: *

    I notice that the bags still smell a little after I remove the inner bag. I would presume this to be volatile oils and though much less than without the inner bags, that they would still become rancid and affect the coffee.

    Whats your experience please?

    Thanks
    Robert

    Ive noticed it too but just put those bags aside to air and use them again later.
    I probably have up to 6 bags in rotation.

    Re: Extending the useable life of one-way bags

    Hi,

    I have to confess that the big clip that I showed off in the first posting here did not stand the test of time. After it hit the recycling bin, I reverted to a clothes peg, holding together folded down corners.

    That was until I discovered the Bag Clip. They come in pairs, red and white, $3, so I bought two sets. They seal a folded over 500g bag very nicely. I picked them up in Melbourne from Nightingale Electrics in Spencer St (which would be worth a visit even if they were out of Bag Clips).

    cheers
    AJ

    Yep,

    I do the same Warren (except I get 8-10 uses from each bag Wink)...

    Thought it might be a useful thing to know for those people who dont own an Impulse Sealer. I imagine it would be quite effective to be honest - Seal via the Zip-Lock and then fold over and apply the Bag Sealer.... Should work OK..... Huh

    Mal.
    So why heat seal the bag - is the zip seal not reliable? Arent you using the zip seal only after cutting the heat seal? Interesting...

    Javabeen.

    Zip is only a stop gap and again only as good as teh person sealing it.

    When ya re use... A bit of coffee dust in the track etc and not a true seal... Thus a heat seal add a lever of backup and additional trust in the process.

    yep, even some new bags will leak out the zip, try it ;) the heat seal is 100% assurity that air will not get IN

    OK OK point taken...but arent you using the zip seal once the heat seal is cut away and opened after youve left the beans to age/degas? Thats what I reallywant to know...dont want to take this too off topic ::)

    Guys, Id appreciate if you would move the bag discussion out of the Roaster thread. As I mentioned a few posts ago, I have revived a bag sealing thread here:
    http://coffeesnobs.com.au/YaBB.pl?num=1218979308/0#31

    Could you please use that?

    thanks

    Yeah javabeen, after the initial resting period i only use the zip lock, the heat seal works well during the resting period, after a while you get to know what beans need what resting periods, when im ready to consume, cut off the heat seal and its all gone in a couple of days, so no hastle there ;) for Monsoon Malaba AA for example, i dont cut off the seal and start consuming until say day 10-12, a LOT of air can get to the beans in that time......

    Thanks for that WS. Looks like heat sealing is the way to go. Ive noticed that lately my old bags have not been inflating as they usually do during degas, indicating the zips are probably failing. Will be interesting to see how they go when heat sealed, so I just ordered an impulse 200mm heat sealer.

    Cheers.
