Hi! I love your videos; they are so helpful, and the bioplastics are so amazing!! I have a question, and I hope you can help me with it. Do you know how I get the bioplastics to be less sticky? When I tried to do the agar agar and the gelatin recipes and use it for the bag they were sticking to each other and everywhere around.
Can we use a normal tray or does it need to be a moulding one? And will it harm the tray in any way? Also if it's a normal tray does it need to be prepped beforehand to prevent it from sticking or something
It makes the bioplastic more sturdy, but it's difficult to show the difference on video. You can do the recipe without it and it'll still work, but it'll be a bit more flimsy.
Hello, love ur videos. Im working on my thesis project for uni and im making some bioplastics. Your receipies have been amazing. I have a question with this recipe. For some reasony pectin doesn't completely dissolve in hot water and it leaves a sort jelly bits. How can i solve this ?
Probably, if it can withstand 80⁰ - 90⁰ C heat, if yes there is also another factor whether or not you need a faster drying, time that needs heat. And one risk factor is glass can break, and/or be a nuisance just by laying it somewhere,
I tried your process for bioplastic made of agar agar however I found out that it's shear strength is kind of weak. Is there any solution for this? Will the shear strength be better for gelatin based?
I have never seen this before, it’s wonderful video but I wonder if you use biodegradable ingredients make the product susceptible to bacteria and how can we solve this problem 😢
That's a problem but at the same time I guess that's what makes them biodegradable, so maybe it can be a good thing in the end? (I'm also not sure, I'm not an expert in chemistry)
HELP! For three days we waited for the drying process and the body of the plastic was covered in molds! How could this happen?? Is it because I used cornstarch as an alternative to pectin? I have heard that cornstarch can be an alternative to pectin. Or maybe because I touched the plastic?
Ok , now make it vegan 🙈🙈🙈🙈 ( I hope it also sounds funny in English and not meen ...or disrespectful or something ...) But seriously ...I would love to see somewhere home I can make this in a vegan way 🙈
amazing work!!!!
We did this for our chemestry project, It worked perfectly! Thanks Giesta
yass girl 🎉
Awesome! Glad to hear that 🙂
Fantastic plastic👍👏👏👏👏
good work zen of giestas
How long does it take to degrade and also how can you make it resistant to water without altering it's properties?
I am a food science student and I have to work on biodegradable things so I need ideas to work on thanks for
This is amazing! Do you know how long this would last before molding and can it be sewed?
How long it lasts is difficult to say, depends on the conditions, like humidity. For sewing I still need to do some tests.

They're a little bit sticky, but if it's too much, maybe they're not fully dry yet.

Thank you for sharing, I have not seen the use of pectin before. What function does it have? Why did you use it?
It makes the bioplastic more sturdy, but it's difficult to show the difference on video. You can do the recipe without it and it'll still work, but it'll be a bit more flimsy.
thank you for the response, I want you to know that I am inspired by your work, greetings. 💫@@giestas
@@rozelinakgun8135 glad to hear that 🙂
i've been following your works since then, and i'm really amazed on the output. please link all the materials you used so we can also replicate 😢

Great vid.. how to get industrial grade pectin in the market?What is that device you use to bind the layers of bioplastic ? Thank you!
All the ingredients are food grade. Heat sealer.
where can I buy the mould??
Is it water soluble?
i hope you will reply 🥹 what can i use aside from silicon molder?

You probably need to agitate the water faster, and introduce the pectin sparsely, using a sieve might help.
@@giestas ok I'll try. thank you so much.
Last question, I don’t have any silicone molder, can I use glass container?
Probably, if it can withstand
80⁰ - 90⁰ C heat, if yes there is also another factor whether or not you need a faster drying, time that needs heat.
And one risk factor is glass can break, and/or be a nuisance just by laying it somewhere,
What is silicon mould lenths and size?
What is the size of your mould?
Hope u can reply soon-Hi,just did this today,i used an electric stove or whats that called,and for 1800w-800w,will that we overcooked?Tysm!
Is the assembling of this plastic bag the same for starch-based plastic? Or will it be more rigid?
Can't say, I haven't tried that yet.
Is there an alternative to pectin?
Silicon moulds size
Please others alternative to pectin
how to do we need to cook it for?
Can this be made without the gelatin?
I tried your process for bioplastic made of agar agar however I found out that it's shear strength is kind of weak. Is there any solution for this? Will the shear strength be better for gelatin based?
Difficult to say without a test , but I'd say they have similar strength.
@@giestasyou can change the pectin with cmc
@@luisazum1447what is cmc?
Is it biodegradable ? If yes then how much time it take ?
Here: czcams.com/video/rGT6VMbwqzc/video.html
Also is there any way to dry it faster?
You can use a dehydrator, like in this project: czcams.com/video/bj0hab1Kga0/video.html
Hey! Other than Dehydrator can we Oven dry it ?
Size of the mould plz
can we replace this bioplastic from PET for water bottles ?
Great work btw
Unfortunately it's not waterproof enough for a water bottle no :/
@@giestas can we use corn starch and foodgrade glycerin for making non porous bioplastic which we can use for storing drinkable water?
@@trishot8213 not sure, it seems to become fragile when in contact with water, as in this case: czcams.com/video/DGp1-hdExMY/video.html
could you please tell me the role of glycerin??? thanks
It's a plasticizer
Plasticizing, which means the material becomes more flexible. You can fold it better without causing cracking.
Is it okay that we didn't put pectin? And is it normal that the bioplastic is still watery even when 1 day had already passed?
Check the FAQ in the description.
I’m trying to make this type of bioplastic，but can you tell me how long I have to simmer for？Thanks！
Not long, just enough for the gelatin to dissolve.
I have never seen this before, it’s wonderful video but I wonder if you use biodegradable ingredients make the product susceptible to bacteria and how can we solve this problem 😢
That's a problem but at the same time I guess that's what makes them biodegradable, so maybe it can be a good thing in the end? (I'm also not sure, I'm not an expert in chemistry)
What was the yellow thing that u mixed? Thank u :)
Right in the beginning? It's neutral gelatin.
can i use this recipe but swap glycerin with agar-agar? and omit pectin?
You can do without pectin. If you don't have glycerin you can try swapping with honey.
@@giestas thank you!
@@giestas i’d also like to ask if the bioplastics mold over time or if it has a long shelf life
@@pancake9162 it's difficult to test how long they last, but I haven't had problems with mold.
What if I do not have plastic sealer? Is there any alternatives?
Check the video description.
can this bag dissolve in water . /like a warm water
Yes.
do you think that this can be edible?
It should be, here is an edible example: czcams.com/video/Brv01vJZ0zY/video.html
Hi, have you ever try to make a bioplastic made from rice hull?
Nope.
@@giestas but do you think its possible?
is there a significant difference if we dont use pectin in creating one?
Check the FAQ in the video description for details.
Q: what kind of gelatin powder that the vid have??
It's neutral gelatin (used for cooking).
Is this waterproof????
I made some tests on that, check the other videos in the channel.
You have to wait for it to dry on its own. or from the sunlight 😅
Both work.
Is that mold is normal rubber mold or some other material..?
It's a silicone mold.

HELP! For three days we waited for the drying process and the body of the plastic was covered in molds! How could this happen?? Is it because I used cornstarch as an alternative to pectin? I have heard that cornstarch can be an alternative to pectin. Or maybe because I touched the plastic?
Difficult to determine the cause, but you can start by trying the recipe without pectin and without cornstarch and see if the se happens.
Can I remove pectin from recipe?
Yes.
Ok , now make it vegan 🙈🙈🙈🙈
( I hope it also sounds funny in English and not meen ...or disrespectful or something ...)
