Introduction: Sugru - How to Make Your Own DIY Sugru Sachet / Save Left Over Sugru

When I open a 5g sachet of sugru I tend to use it all but sometimes there is a little piece left and often this is where I get really creative, thinking of what to do with the leftover piece.... :)

...some people like to save their left over sugru for later but as sugru is a moisture cure material, it is very difficult to stop it from curing :(

This is a simple and easy to do project to help you save your left over sugru for later :)

N.B. your DIY sachet should save your sugru for a while but will not as good as the original sachet

The sachets that your sugru is packaged in is not ideal to use for DIY sachets as there is a residue of sugru there that does not allow for a good seal :( The pouch material is clean which makes it ideal for the job.

Step 1: Use Your Sugru Pouch

To make your DIY sugru sachets, you can reuse your sugru pouch for it's moisture barrier foil.

You can make 4 good sized sachets from the Smart Hacks Super Pack and 4 smaller sachets from the Smart Hacks Pack :)

Step 2: Cut 1


First of all, cut the top and bottom from the pouch, these parts can not be used for your DIY sachets.

The is a gusset at the bottom of the pouch, make sure you cut above this.

Step 3: Cut Into 4 DIY Sachets

Now cut the middle section of your pouch into 4 squares - each square will be big enough to hold at a full 5g lump of sugru. It should also be big enough to save a new mixed colour over 5g :)

Step 4: Create a Seal

In order to prevent your sugru from curing in your DIY sachet, you will need to create a moisture barrier seal.

Use your domestic clothes iron and the edge of a steel sink.

Turn the iron on to max heat.

Place one side of your sachet flat onto the side of your sink.

Press the iron down firmly onto the sachet for at least 1 second. Do not move or slide the iron, simply apply firm downward pressure.

Make sure that you have applied the pressure along the full length of your sachet. It is unlikely that all the surfaces are flat so perhaps applying the pressure at 2 or 3 points along the sachet will achieve the best result.

You should create a seal that is at least 3mm wide but 5mm is an ideal width.


Step 5: Complete DIY Sachet - Ready for Your Spare Sugru

Your sachet should have seals on just 2 sides forming a right angle.

From our experience this is the best way to make, fill and seal your own sachet.

Prepare all 4 of your sachets now and have them ready for your spare sugru.

Step 6: Pop Left Over Sugru Into DIY Sachet

When you want to save your left over sugru, pop it into the sealed corner of your DIY sachet.

Step 7: Prepare DIY Sachet for Final Seals

In order to achieve the best possible moisture barrier, you need to make your seals as flat as possible and avoid creases in the foil.

Gently press your sugru in the sachet so that it is relatively flat - be careful to keep the sugru in the sachet away from your seals as this will compromise your seal quality.

Next press down the foil along the first edge and squeeze it outwards to make both sides of the sachet flat and smooth.

This is ready to seal with your iron.

Step 8: Create Final Seals

Iron the third side of your DIY sachet as before.

Once this side is sealed, prepare the final side of your sachet as before making sure that the foil is flat and crease free.

Step 9: Booster Seal

Finally, I would recommend additional corner seals on your sachets, this is usually the weakest point of your sachet.


Step 10: All Finished With 3 Sachets to Spare :)

Here is my completed sachet and three spares :)

Today (Thursday January 20th) is day 3 of my experiment to see if my sugru stays uncured in my DIY sugru sachet - and I am delighted to report that it's still perfect :)

I will keep you posted on any change...

Would it work to just use plastic wrapper?

Hello, just reporting back regarding the hot knife sealing technique, i am still a computer luddite and cant send a photo of my botch job.
Anyway my son was playing football in his room and broke his light so i got out the last pack of sugru the one i had sealed with the knife, it still felt squidgy so i opened it and it was as good as gold as soft as before, i bought the pack at christmas and the used by date was october i had been keeping it in the fridge also. so all is well, cheers sugru.

i am having trouble replying, as i am not very computer literate, i cant even upload a picture, i have had another look though and i left to much air in as i didnt really take very much care with it, just thought i would try, but its still soft, sorry if you are receiving multiple replys from me.after tectsro

How long did it last in the DIY sachet?

author

Hi, I tested this for about 2 weeks and it was still good, it really depends on the quality of the seal you create but I would recommend about 2 weeks.

You know if you open one side of the 5g sachet you can reseal it with those food bag sealers really easily, it'll be a better seal than folding alone plus no need for chopping up, I can attest to it working for a few days.

You could add silica gel in the bag! so as to remove moisture in the bag! because food bags generally are quite big!

That would do exactly what you want to avoid. I'd prefer not doing anything counter-productive, thanks :)

Why would it be counter-productive? isnt the idea to remove mositure? :S

author
timothymh made it! (author)timothymh2011-01-22

No: If I'm not mistaken the whole idea is to keep the moisture in, to keep it from drying out. But maybe that's not true...

author
shanmugammpl made it! (author)shanmugammpl2011-01-22

It says that sugru cures with moisture... and since the air is moist sugru cures in air...at room temp. therefore you would want to remove any moisture from the package!

projectsugru made it! (author)projectsugru2011-01-24

hi timothymh and shanmugammpl, just to answer both your questions. sugru is a moisture cure material, the moisture in the air reacts with sugru to make it cure so the purpose of the sachet is to keep the moisture out. On the other hand, the volume of air that gets locked inside a sachet is negligible, so there is no need for silica gel. Hope this helps :)

Thanks, as for the comment on the wineglass one, so far moisturizer, fiber putty - the hair gel and olive oil have all worked great as a way to stop your hands sticking to it.

Hey y'all. Use a bit of parchment paper (from the baking section of the grocery store) between your iron and any plastic you're trying to weld. Should help avoid icky situations.

I have read about making your own faux Sugru from silicone caulk and corn starch, I must try this sometime...

evilution made it! (author)2011-01-20

I find that it's very easy to separate into 2 or 4 pieces whilst it's still inside the sealed packet, then I stick the packet in my cheap eBay heat sealing machine.
Make separate compartments for each piece and use them as you see fit.

projectsugru made it! (author)projectsugru2011-01-20

Hi evilution, sounds interesting. Do you reseal an unopened sachet into 2 or 4 mini sachets before opening it ?...

James

author
projectsugru made it! (author)projectsugru2011-01-20

If this is the case, there is a very strong chance that there will be sugru in your seals. Moisture will travel through the sugru and cure the sugru within the sachet :( However, a cheap heat sealer is perfect to make your own sachets from the pouch which eliminates the risk of getting sugru in your seals :)

author
evilution made it! (author)evilution2011-01-20

Well technically you can't reseal a packet that hasn't been opened but I wouldn't want to appear pedantic lol.

Yes, I partition the sachet before opening and it seems to have preserved the unopened blobs perfectly. You can always do 2 seals right next to each other just in case if you wanted.

I don't mean to sound too uninformed. What is sugru? A sentence or two explaining what it is would be helpful then, go into the instructable.

Hi Foxtrot70 - the very best way to discover sugru is at sugru.com :) Watch thr video on the home page, check out the gallery and then take a look at the blog :)

Hi James - I just viewed the sugru website. Very interesting, I see this could be used as a really quick mould compound for a quick one-off item. Thanks for the reply and the link.

Massive kudos to you guys for publishing this. Most companies selling perishable products wouldn't want their consumers to know this kind of trick for fear of them not buying as much of it. If anything, knowing I can do this would make me open a packet sooner rather than waiting around for several fixes to do.

Agreed. I've been looking for something to do heat seals like that for a while, but haven't thought of anything quite so simple (though a rig with the heating element out of a toner printer would be cool).

skimmo made it! (author)2011-01-20

that,s pretty damn savy, do you think it will work for mi goreng flavour packets?

author
projectsugru made it! (author)projectsugru2011-01-20

Hi skimmo, yeah, it should, but the trick will be to find the correct temp on your iron for welding the plastic they use for Mi Goreng package. Too hot and it will stick to your iron and make a mess, too cold and it just won't weld :) Definitely worth testing though, perhaps worth a dedicated Instructable ?......

I'm on this website for a while now, and I've seen several ideas already, how to use Sugru. And I love them.
But...What is it!?
What is the material?
What's it made from?
Is it clay? Is it plastic?
Is it sticky? I think you have several colours Sugru, isn't it?
I'm asking, because we might have an alternative in The Netherlands I can use. Just (very) curious.

author
Mister-B made it! (author)Mister-B2011-01-18

It is like a clay first, and after a while it hardens to a silicone stuff. You can stick it to something, and it won't come of, but after it hardens, it isn't sticky anymore. It's patented and pretty know so I don't think you'll find anything like this. But it's from England and the shipping is really cheap. So just buy some on sugru.com
