Frequently Asked Questions

What is gelatin film?

Gelatin film is a thin, flexible, and biodegradable sheet made from gelatin, a natural protein derived from collagen. Gelatin films are widely used in food packaging, pharmaceutical capsules, edible coatings, and biomedical applications due to their excellent film-forming ability, transparency, and biodegradability. They provide a sustainable alternative to synthetic polymer films and can be enhanced with additives for improved mechanical strength, moisture resistance, and functional properties.

How to make gelatin film?

To make gelatin film, gelatin powder is first dissolved in warm water to form a uniform solution. Optional plasticizers such as glycerol or sorbitol can be added to improve flexibility and reduce brittleness. The solution is then cast onto a flat surface or mold and allowed to dry at controlled temperature and humidity until a thin, transparent film forms. The resulting gelatin film can be further treated, cut, or coated depending on its intended application in food, pharmaceuticals, or biomedical fields.

What types of gelatin membranes can you prepare?

BOC Sciences can prepare a variety of gelatin membranes, including homogeneous films, porous membranes, electrospun nanofiber membranes, and composite or functionalized films. Each type can be tailored to specific mechanical, thermal, or biological requirements.

Can you provide custom formulations for gelatin film preparation?

Yes. We offer precise customization of gelatin molecular weight, concentration, crosslinkers, plasticizers, and polymer blends. This ensures the final film meets desired properties such as flexibility, transparency, biodegradability, or drug release behavior.

What membrane preparation technologies does BOC Sciences use?

We employ multiple preparation techniques including solution casting, phase separation, electrospinning, and chemical or physical crosslinking. Each method can be optimized to achieve uniform structure, porosity, and functional performance of the gelatin film.
