Water Soluble Polymer Film - A plastic film that disolves in both hot and cold water
QUESTIONS & ANSWERSAsk a Question
How long does it take this polymer film to dissolve in sea water?
It depends a lot on the temperature of the water, but at water temperatures between 10 and 20 degrees celcius the material will dissolve within a couple of minutes.
Is this safe to consume?
The polymer film is not certified for human cunsumption. But there are other products that are - check for example https://www.notpla.com/
How big can you make bags that are water soluble? How strong are they? Could they be used as grocery bags or trash bags?
The material comes on rolls, so it is possible to make very large bags. The film has mechanical properties similar to normal plastics and the strength depends on the thickness of the film. They can be used for grocery bags as long as you don't get them wet.
I'm looking for a film that is water-soluble in 1-3 min. Is this a product that you have?
We only have the described sample. The manufacturers can adjust the formulation of the polymer to control the dissolution time.
PVA plastic dissolves if it comes in contact with water (example: finish dishwasher tablet coating ) my question is does it emit any vapors or fumes or does it just dissolve in the water without any other reaction?
It just dissolves with no visible reaction, similar to the way sugar dissolves in water.
Will this still lead to plastic entering our waterways? Plastic is still an issue - even if it is tiny!
The manufacturer states that the polymer breaks down on contact with water to become feedstock for micro-organisms. You can read more here.
How quickly does this dissolve? Is it available as clear plastic?
The time it takes to dissolve depends on the water temperature and how agitated the water is.
The sample we stock dissolves within a minute or two in lukewarm water.
Our sample has a yellowish tint, but some variants of the material are more clear.
