Bio-Based Flexible Protective Film

Official patent title

Bio-based wearable films and method of preparation thereof

Arabic title: أغشية حيوية قابلة للارتداء وطريقة تحضيرها

Invention

Problem

Disposable wearable films commonly depend on petroleum-derived materials that are nonrenewable, difficult to degrade, and can create waste, comfort, or material-compatibility concerns.

Why it matters

Wearable barriers are widely used in medical, protective, and personal products, so alternative material platforms could reduce reliance on conventional petroleum-based film structures.

Approach

The film combines acid-hydrolyzed palm stem pith with starch, cellulose, a synthetic polymer, plant hydrogels, glycerin, and a plant-derived dye. A controlled sequence of blending, heating, acid treatment, curing, and drying forms the wearable film.

Who may benefit

Potential beneficiaries include manufacturers of gloves and protective garments, medical-material developers, sustainable packaging and film researchers, and date-palm biomass processors.

Potential value

The disclosed formulation introduces palm-derived and plant-hydrogel components into a wearable film while retaining a defined fabrication route and reported mechanical and water-resistance characteristics.

Background

Wearable films such as gloves provide barriers in medical and protective settings, but many conventional products are made from petroleum-derived materials. Their disposable use consumes nonrenewable resources and creates persistent waste. The publication also notes practical concerns associated with tight, poorly breathable synthetic gloves, including sweating, itching, powder-related dryness, and allergies for some users. It proposes a film platform incorporating date-palm material, cellulose, plant hydrogels, glycerin, and a natural dye within a controlled manufacturing process.

Technology overview

Palm stem pith is blended with water, heated, and acid-treated before being mixed with starch, cellulose, polyvinyl chloride embodiments, aloe vera, okra and Acacia arabica hydrogels, glycerin, and Bougainvillea-derived dye. The mixture is adjusted, heated to cure, and dried into film. The publication describes compositions, processing ranges, nanocellulose content, and standardized water-absorption and crack-test results for the described material embodiments.

Potential applications

Protective gloves or glove layers for further material and user-safety evaluation.
Films for masks, gowns, finger cots, or dental dams described as potential article forms.
Wearable medical-device surfaces or coatings requiring flexible film materials.
Exercise bands or other personal products formed from a wearable film.
Research platforms for incorporating date-palm biomass and plant hydrogels into functional films.

Evidence-supported advantages

The formulation incorporates palm stem pith, cellulose, plant hydrogels, and a plant-derived dye.
The publication provides a defined sequence for blending, acid treatment, curing, and drying.
Reported embodiments cover several wearable article forms rather than a single glove geometry.
The disclosed film includes reported water-absorption, carbonate-content, and crack-test characteristics.
Composition ranges and processing temperatures are specified for manufacturing evaluation.

Development stage

The publication describes fabrication and reported material testing under ASTM D570 and ASTM D5419; commercialization was not established.

Commercial opportunity

The material could be explored with protective-product and specialty-film manufacturers through licensing or formulation partnerships. Product development would require biodegradation, biocompatibility, barrier, durability, comfort, sterilization, and scalable manufacturing studies for each intended wearable application. Benchmarking against existing films would also be needed.
