Our material is a family of non-acetate Polyvinyl Alcohols (PVOH), it is one of the few materials soluble in water that is also susceptible to final biodegradation in the presence of microorganisms typical of all ecosystems.

PVOH is a material with the property that it possesses an oxygen barrier similar to the copolymer of ethylene and vinyl alcohol.  (EVOH), but which, in contrast, has certain peculiarities, such as relative solubility in water and biodegradability.

PVOH should not be confused with polyvinyl acetate; a popular wood glue.

PVOH is a synthetic polymer and is a substance made up of many molecules linked together. PVOH begins its life as ethylene (a natural gaseous hormone emitted by plants; one of its functions is to help plants ripen their fruits. In our case, ethylene is produced synthetically (but it is identical to what you can found in nature), which undergoes a chemical reaction with oxygen and acetic acid (in a dilute form known as vinegar), then polymerizes (joins to form repeating molecules), then transforms into a family of alcohol to finally result in a water-soluble or water-soluble polymer.

>>> It is a water soluble material

​

>>> Does not pollute

​

>>> Polyolefin repellent

​

>>> According to formulation, it solubilizes in 3-9 seconds on contact with  Water

​

>>> They dissolve completely in 4 to 5 minutes once in contact with water at 90 ° C. Those formulations for hot water will not be soluble in water with a temperature below 20ºC, however they will gradually biodegrade from 23 to 45 days as a result of the interaction with microorganisms without leaving microparticles or microplastics.

​

>>> Human and wild life can ingest its contents without any problem. Easily integrable into ecosystems without altering them

​

>>> Does not contain any chemicals

PVOH is highly soluble in water (water soluble), totally biodegradable and free of microplastics (according to the latest ECHA 2018 study), it is resistant to solvents and oils, it has exceptionally good adhesion to cellulose as well as to other hydrophilic surfaces.

It is moldable but strong, flexible and functions as a high oxygen and aroma barrier. It has a slight French note of acetic acid (vinegar), it is non-toxic and resistant to fats, oils and solvents.

​

When the degree of alcoholysis is less than 88%, polyvinyl alcohol can dissolve in water at normal temperature, altering it will change its solubility temperature or its mixture with other conductors such as starch; for example, when alcoholysis reaches 97% its solubility will be in hot water at 60-80ºC.

PVOH is the only polymer that is not obtained by polymerizing a monomer. PVOH is produced by hydrolyzing polyvinyl acetate, the amount of hydroxylation determines its physical and mechanical properties. While other vinyl polymers are prepared by polymerizing its monomer, PVOH, it undergoes partial or complete hydrolysis of polyvinyl acetate to remove acetate groups.
