Homemade Bioplastic: bag

[@Mariam-ne7cf]

We did this for our chemestry project, It worked perfectly! Thanks Giesta

[@giestas]

Awesome! Glad to hear that 🙂

[@juliemiamba862]

How long does it take to degrade and also how can you make it resistant to water without altering it's properties?

[@Lunarl4ndr]

I'd love to see some stress tests of this plastic. Seems fairly strong already, but could probably be reinforced with cellulose or animal fiber for added strength.

[@fernandoconte2990]

amazing! thanks for sharing , I´ll love to do it with my students!!

[@harshasree2016]

amazing work!!!!

[@emmanuelmatewere7575]

Thanks for the amazing video @giestas, i was curious to know what ingredient makes the bioplastic heat sealable. I tried with other materials like cassava starch and agar agar following your previous tutorials but they couldn’t seal with an impulse sealer.

[@giestas]

It's probably the gelatin itself, i'd guess.

[@tatianaaisya]

if i were to replace one of the ingredients with a seaweed called E. Spinosum or add it, would it work? please respond i really need this

[@rozelinakgun8135]

Thank you for sharing, I have not seen the use of pectin before. What function does it have? Why did you use it?

[@giestas]

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.

[@rozelinakgun8135]

thank you for the response, I want you to know that I am inspired by your work, greetings. 💫@@giestas

Se puede utilizar pectina de manzana casera?

[@giestas]

Good question, I never tried that.

[@joshuanieva1183]

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?

[@giestas]

Difficult to say without a test , but I'd say they have similar strength.

[@luisazum1447]

​@@giestasyou can change the pectin with cmc

[@donnamayferrer1829]

[@AshleyTsaqofi]

You can add more agar concertation and glycerin

Is there any other substitute for pectin? Something which is easily available? Please do suggest

[@almaesprila4730]

question can cassava starch work the same way?

[@strategicfops7896]

@Giesta what is the use/purpose of adding Pectin? Can I get reactions for this?

[@kirtisawant9288]

Pectin makes the bioplastic sturdier. You can make the films without it too, but they will be more flimsy and won't be able to handle more weight and will perform poorly in strength test.

[@xyke1210]

You mentioned that the fastest way to dry it is by using a dehydrator. How long should it be left in the dehydrator, and at what temperature? please i hope i get a response 🙏

[@aether5531]

how long do we have to simmer the water and when the hydrated gelatine is placed?

[@giestas]

Just bring the water to a gentle simmer, no need to wait longer.

[@toadslap9749]

Would there be a way to draw/impose images or lettering onto these bags that is also earth conscious?

I haven't even started exploring that, but I hope I'll get to it sometime.

[@shanemalabanan1706]

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?

[@giestas]

Check the FAQ in the description.

[@shallotmokabane7055]

Can you make cups from this? Can you harden it to make cup?

[@giestas]

That's difficult because you need a waterproof material to make cups.

[@samanthadaniellemanalo2942]

Is the assembling of this plastic bag the same for starch-based plastic? Or will it be more rigid?

[@giestas]

Can't say, I haven't tried that yet.

[@rayssamoraes7428]

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.

[@giestas]

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

[@jannahjappar2210]

how can make it dry? outside with the sun or it needs a machine or equipment? mine develop molds, and it hasn't dried yet for almost three days. what could be the problem?

Maybe it's the surrounding conditions, like a high humidity location, or cold weather?

[@atldiego1]

[@Sub1n_]

Last question, I don’t have any silicone molder, can I use glass container?

[@Qrcrap]

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,

[@ryll9921]

Is there a way to glue the 2 pieces together? I also used a heat sealer like you but it didn't work, the two pieces couldn't hold together and easily slipped off, and if I used too much heat it would tear the whole wrapper, please explain, please i need your helppp

[@giestas]

Difficult to say without seeing the object, but maybe you can try to introduce a bit of humidity (a tiny bit of water) in the parts that you want to fuse together? I remember seeing a comment somewhere suggesting that.

I know it's more for fun and school projects, but since it's not water resistant, it's really poor choice for packaging fruit. I mean it looks great and it's a cool thing by itself, but I see more uses of it as an edible plastic substitute, perhaps for cake decorating and such, instead of regular plastic. For packaging people still should use reusable bags. Up until 1990 it was common to make your own fruit and vegetable mesh bag by crotcheting, where I live.
