Both can work as long as it's a material with some temperature resistance. You can also just use tinfoil on your kitchen countertop for regular starch bioplastic.
Is this bioplastic biodegradable? Does adding a gauze layer mess with the biodegradability of the bioplastic? And can these be made into plastic sachets?
In this video you can see how it degrades: ruclips.net/video/oub-YroMsR0/видео.html and the gauze is made of cotton, so I'd guess is still biodegradable.
I've watched all your videos, I still can't figure out what should I do to make my bioplastic flexible and not brittle. I used a different starch ( I extracted starch from rice through decantation) but the starch is wet is it the problem why my bioplastic is not working? Is starch should be dry? Or should I adjust the measurements. I followed the same measurements with yours. Please help mee🖤
Usually, brittle means not enough plasticizer (glycerin). If you added enough plasticizer, then the issue is probably the starch extraction method, but I haven't explored that myself yet.
@@giestas Thank you very much! I've tried you recipe and it's already less sticky and stronger then a recipe I've tried last week which is still not dry.
your content is amazing. will wait for the water-resistancece tests
Muito interessante, gostaria de ver a experiência com um material menos maleável. Obrigada
Thank you for your kindness!! I have a question. Is a meterial of flat surface glass? or plastic?

thank you, your research is so inspiring! can I substitute starch + vinegar with gelatin powder?
That would be a different recipe: ruclips.net/video/Ty0O2VmbNeE/видео.html
And will the reinforced bio plastic will have strength?
Amazing!!!!
Can this rolled into tube like structures

In what proportion should I use potato starch instead of cassava starch
It's a different recipe: ruclips.net/video/Uaz9Qvadyio/видео.html

@@giestas okayyy thankk you so muchh I'll try increasing the glycerin's measurements
@@reaando1678 Cool, let us know if it works out :)
If made in a bulk tank, do you think this would work as a dip? I am thinking mostly for short term water resistance on fabrics or shoes....
As a dip, interesting! I hadn't thought of that.
Meanwhile I guess I should test these to see how water resistant they are.
What weee the dimensions of your sheet?
Does it also work with a different type of starch?
It does, but the ratio of ingredients is a bit different.
You can find the recipe in the video "BIOPLASTIC DIY: potato starch vs. corn starch".
@@giestas Thank you very much! I've tried you recipe and it's already less sticky and stronger then a recipe I've tried last week which is still not dry.
can we cut it using scissors
Yes!
@@giestas which one is most stretchable / flexible, without gauze, single gauze, double gauze
@@Kritika_2008 without, for sure.
@@giestas thanks a lot
@@giestas does the type of starch affect the final bioplastic. If does then how?
Is there a way to decrease the setting time?
Reducing the amount of water is the simplest way, but it changes the aspect of the bioplastic ( ruclips.net/video/1hDXsOrf0AY/видео.html ).
Can you try starch from rice?
Good idea; rice starch is quite expensive around here, but I'll try, it might be useful for people in places where it's more common.
@@giestas ok thankiess, but I have a suggestion, can you try extracting starch from rice through decantation and use it in making bioplastic?.
@@reaando1678 that's quite a challenge, I'll probably give it a go after I finish ongoing experiments.
can you help me, I'm making a large quantity of this (100*125cm) and this mixture cracked on all three samples
the layer was thinly spread
@giestas
Take a look at these samples ruclips.net/video/1hDXsOrf0AY/видео.html and see if you find one that matches.

@@giestas Can I speed up the drying process by using a hair dryer?
