Homemade Bioplastic: heat-sealed packaging

[@Hasan_Akdogan]

Thank you so much I have finally did my first useful bioplastic (try 14). I will join science competition with lots of package types.

[@giestas]

Awesome, good luck for the competition!

[@Hasan_Akdogan]

@@giestas thanks.

[@JannelleQuidet_gonzales]

If you don’t mind me asking, why did it take you 14 tries?

[@Hasan_Akdogan]

@@JannelleQuidet_gonzales I tried different mixing ratios

[@wingszelo7737]

@@Hasan_Akdogan Can i know what makes the different ratio different plastic? We are thinking to set up Hypothesis for a science fair

[@brianivandertp]

I'm in love with your videos!

[@deborahdaviesdd-artist1059]

Amazing. Love your videos. Finally a use for my straightening irons 😂

[@harshasree2016]

Hello, your videos are really inspiring. Can you make a video on how to make bioplastic from seaweeds pls

[@vincentmasella8145]

So inspiring

[@rajruban637]

Can we use any type of glycerine

[@jemajoy8839]

Awesome! ❤

[@joshuanieva1183]

Is it required to put it in a dehydrator? Or is it also possible to get same result by drying under the sun for several days?

[@giestas]

Depends on the ambient conditions (high humidity area/ winter time) but it is possible to dry in open air yes.

[@Karlampongan]

How many minutes/hours/days it take to make the bioplastic dry?

[@pencillia..6271]

Please i request you to suggest any alternative of dehydrator. Can we use oven/microwave or can we only dry it through the sunlight ? And if in oven how many hours we have to put in it into ?Pleasee reply ...

[@giestas]

Most ovens are too hot to function as a dehydrator.

[@Torisfiless0308]

hello! what can we add to the bioplastic to make it more durable and flexible?

[@dianapaolalargocastro3736]

I need your help, when I make the bioplastic and when I remove it from the mold it wrinkles. What can I do for this?

[@giestas]

Hmm... difficult to say without more information, maybe you're removing it from the mould too soon?

[@dianapaolalargocastro3736]

I prepare it at the Laboratory level, so I can't leave it at room temperature for 3 days. Use a drying oven at 35°C. The bioplastic wrinkles and becomes very thin. I don't know what to do to improve the appearance. Please help me@@giestas

[@arroio_x_giestas]

a drying oven is perfect, so that shouldn't be the problem. Is there a chance you didn't add enough glycerin?

[@d.a.v.i.d.6495]

Genious guy👍

[@charlienicholsonr]

I'd really like to see you vaccum form agar bioplastic. Do you happen to have an agar recipe that can make thinner, stiff bioplastic?

[@giestas]

Something like this: kzbin.info/www/bejne/iqqTgGWMoseBm6c

[@strawberryiee752]

Hi there! If one doesnt have a dehydrator, Is it best dried in open air, if so how long do you think it would take? Second, can it be oven dried? If so what tempt can be used and how many minutes? Thank you ! 😅

[@giestas]

Depending on humidity levels where you live, it might get dry in 3 days. I haven't tried the oven, but I'm guessing it'll introduce bubbles in the material.

[@zeinabzarei4002]

😍 amazing

[@34lokeshhatzade74]

Is these bioplastic cost effective? If yes then how much cost of one bioplastic bag

[@최리나-f6z]

1.Why is Pectin added? 2. What kind of physical properties will change if you add agar instead of gelatin? Thank you ◡̈

[@giestas]

1- pectin makes it easier to handle, but its difficult to show the difference on video. You can make the recipe without pectin if need be. 2- if you use agar you'll get a nice bioplastic also, but the sealing method might not work. I have to make some more tests on that myself.

[@brianivandertp]

So if we want to seal the plastic, we must use gelatin?

[@brianivandertp]

So if we want to seal the plastic, we must use gelatin?

[@giestas]

@@brianivandertp it appears so, but like I was saying, not 100% sure, I still have to make more tests.

[@charlienicholsonr]

I'm wondering, if I took away the pectin, and replaced the gelatin with agar, would I make the same sort of packaging-like material that's crinkly but strong, but formulated with agar instead?

[@giestas]

Hand here you can see how the agar handles: kzbin.info/www/bejne/i6SciXSwn7eBsKc

[@lucianaguerrero9146]

hi! could you tell me step by step so I can do it adequately please? I would really appreciate it :)

[@jemal6261]

Is there any kind of pectin? There are various pectin that shows whenever i search for it. Are you using a citrus pectin or what????????????????????????????

[@Torisfiless0308]

up

[@MyLofi-Motivation]

how long this food packaging by bioplastic can store in normal temp/condition ?

[@giestas]

Difficult to say exactly how long, but it's a surprisingly long time.

[@MyLofi-Motivation]

@@giestas Thank you

[@Brendavesch]

Will there be any change if it doesn't have pectin?

[@giestas]

The resulting bioplastic will be more flimsy (it's difficult to show the difference on camera).

[@wingszelo7737]

@@giestas Can i use Aagar to replace pectin? And why don't you add starch when making bioplastic?

[@lizinny1580]

How long did you put the bioplastic in dehydrator? Is it 24hr? Or less?

[@giestas]

8 hours

[@TurtlesAndTortoises302]

Would this bioplastic eventually collect bacteria if food was stored inside it? Since agar and gelatine are the same jellies used in petri dishes

[@giestas]

I would imagine so, hence the dehydration.

[@LM-tr1bh]

do you think it can be used instead of shrink band with a heat gun (for bottle neck and cap) ?

[@giestas]

No, it doesn't behave like heat shrink wrap, but that would be an interesting use case.

[@LM-tr1bh]

@@giestas ok I understand. Can you help with that ? 😃😋 Thank you for your reply.

[@giestas]

I've been doing some experiments, a video will come soon.

[@LM-tr1bh]

[@witra88]

How about sealing function from vacuum sealer machine? Would it be too hot?

[@giestas]

That'll be for a future video!

[@AliyahAveryMonroe-tr1gm]

I do have questions again, sorry😭. Do you think that if I use gelatin and agar-based bioplastics as food packaging for items like bread, beans, vegetables, and fruits, the foods will stay fresh similar to traditional plastics? Uh if yes how long you think it will be?

[@AliyahAveryMonroe-tr1gm]

How does gelatin and agar-based bioplastics decompose? Can they be submerged in water and buried in soil to decompose? How long does this process take?

[@IAm-un9ny]

Is there an alternative to pectin?

[@brianivandertp]

Why do you use pectin? The glycerin is for flexibility right?

[@giestas]

The pectin makes it more durable and easier to handle, but it's difficult to show the difference on camera.

[@giestas]

Glycerin makes it flexible yes.

[@tonybeatbutcher]

This process works with PLA?

[@giestas]

I don't know :/

Hi, I want to make a perfect bioplastic for our experimental research. Can you please suggest a perfect ingredient like potato, corn, agar, and gelatin to make bioplastic cellophane food packaging? Please I need your help.

[@AliyahAveryMonroe-tr1gm]

Also, the cellophane food packaging that I want to achieve is flexible, water resistant, and clear. I watched your videos, and I want agar as a main ingredient. Would agar be perfect? What do you think? Hmm, what ingredient will be suitable for you?

[@AliyahAveryMonroe-tr1gm]

Please help me with my research🙏

[@AliyahAveryMonroe-tr1gm]

Do you have an idea about what packaging what I want to have? I can send a pic for reference in ig? Pls pls help, thanks

[@giestas]

Both gelatin and agar can work for you: kzbin.info/www/bejne/i6SciXSwn7eBsKc

[@giestas]

If you don't mind it being from animal origin, maybe gelatin can behave a bit more similar to the type of packaging you want.

[@JannelleQuidet_gonzales]

Where do you store the bio plastic to dry?

[@giestas]

Ideally in a dry warm environment, close to a sunny window, for example.

[@JannelleQuidet_gonzales]

Are there any alternatives for glycerin?

You can use honey: kzbin.info/www/bejne/ooaUg5yHidJ_q6M
