- a stretch film according to the invention exhibits advantageous properties for use as a cosmetic mask and biodegradable stretch food film.
- Patent CN101298507 describes the preparation of a packaging film composed of material derived from biomass.
- the raw materials for making the film are KGM [(C20H32O16) n], carrageenan (C12H16SO10) n], glycerin (C3H803), sucrose fatty acid ester (C30O12H56) and water (H20 ).
- CN108559276 describes an edible soluble film with added soybean fiber.
- This film consists of soybean fiber as the main raw material, to which sodium carboxymethylcellulose, glycerin, konjac gum, and carrageenan are added to the solution.
- This film contains between 0.5 and 0.8% by mass fraction of konjac gum and 0.5 and 0.6% by mass fraction of carrageenan.
- Patent FR2963888A1 describes a particular cosmetic hydrogel comprising a gelling and thickening complex based on carrageenan, glucomannan and galactomannan.
- the hydrogel composition according to the invention optimally comprises between 0.2 and 2% of carrageenan by hydrated weight of the hydrogel composition, between 0.2 and 2% of glucommanan by hydrated weight of said composition, and between 0.2 and 2% of galactomannan by hydrous weight of said composition.
- WO2006 / 053333 describes a cosmetic mask comprising an insoluble support and a gelled composition.
- the gelled composition is composed of two separate gels, one comprising a polymeric, water-soluble gelling agent and the other comprising a strengthening agent.
- the inventors have shown that the combination of konjacet with carrageenan makes it possible to obtain a gel with very advantageous properties in terms of elasticity and resistance, which can be stretched in the form of a film. These unique properties reflect the synergistic effect specific to the combination of konjac and carrageenan in proportions between 20/80 and 60/40.
- the invention relates to a composition of biodegradable stretch film type comprising konjac and carrageenans in which:
- the konjac / carrageenan mass ratio is between 20/80 and 60/40 and
- the total mass percentage of konjac and carrageenans is between 0.5% and 2%.
- the invention also relates to the use of this composition for the preparation of a patch for topical use as well as kits for topical use comprising such a stretch film composition.

- This stretchable film exhibits novel properties which are particularly suitable for use as a cosmetic mask or patch. These properties are achieved only through the combination of konjac and carrageenans in a defined ratio. In other words, no other component is necessary to obtain these properties, unlike the compositions generally known from the prior art. It can be used alone for its anti-drying properties and its freshness effect.
- a cosmetic composition is placed between the film and the skin.
- the film constitutes a physical barrier vis-à-vis the outside world.
- the cosmetic composition deposited on the film is protected from oxidation during the time of contact with the skin.
- Vitamins or other molecules sensitive to oxygen can act optimally on the skin.
- the mask can be applied for several hours without drying out.
- Another advantage of the film is that it adapts perfectly to the morphology of the surface to which it is applied. It can be the shape of the face in the case of a cosmetic mask but also any other part of the body on which you want to apply a patch: ankle, knee, hand ... This adaptability results from a combined high elasticity good resistance to breakage.
- the properties of this film give it a "second skin” effect.
- the film exerts a certain surface pressure on the skin conducive to the diffusion of the active principles through the superficial layers of the skin.
- the film produces a persistent freshness effect.

- biopolymer film for biodegradable and compostable food use, in other words a plant cover, as well as kits for preparing such a film.
- stretchable food films can be applied by resting on the edges of a container containing food or directly in contact with food. Being made of edible raw materials, they do not present any danger to health, even after prolonged direct contact with food.
- the advantages described above for cosmetic applications can also be used in the food industry. Indeed, thanks to its great stretchability, the film adapts perfectly to the shape of the food to be protected. It protects them from oxidation and dehydration for at least 24 hours, if not longer. It is easy to prepare and handle. Remember that it is compostable and biodegradable, like food waste.
- the stretch film according to the invention can be in different forms.

- the mass ratio between konjac and carrageenans is between 25/75 and 50/50; this ratio makes it possible to reconcile good elasticity and good resistance to stretching.
- the 35/65 ratio provides maximum synergy but this ratio can be modulated according to the applications.
- a ratio of between 30/70 and 55/45, or even between 35/65 and 55/45 makes it possible to obtain properties suitable for an application as a stretch film.
- a ratio between 40/60 and 45/55, and each of these two ratios are particularly advantageous.
- a 60/40 ratio is possible when the solvent is distilled water.
- the term “konjac” means a powder of Amorphophalus konjac, a vegetable in the form of a tuber cultivated in South-East Asia. It can be a whole flour obtained by grinding the tuber or glucomannan purified from konjac.
- the carrageenans used are Kappa or k-carrageenans carrageenans.
- the physical properties of the film are based solely on the synergistic effect observed thanks to the mixture of konjac and carrageenan.
- the invention relates to a composition of biodegradable stretch film type containing konjac and carrageenans in which:
- the konjac / carrageenan mass ratio is between 20/80 and 60/40 and
