Instructions for use of bacterial cellulose films

Bacterial Cellulose Film (BCF) is a natural biological material produced by fermentation by bacteria such as It has high mechanical strength, excellent flexibility and biocompatibility, and has a wide range of applications in medical, food packaging, electronic devices and other fields. The following are instructions for using bacterial cellulose films:Acetobacter xylinum .

1. Storage instructions

• Environmental requirements : Bacterial cellulose films should be stored in a dry and cool environment to avoid direct sunlight.

• Temperature : The recommended storage temperature is between 4°C and 25 °C . Higher temperatures may affect the performance of the film.

• Humidity : Maintain a low humidity environment to avoid moisture from the film to prevent changes in its physical properties.

2. Prepare before use

• Cleaning treatment : Before use, gently rinse the film with distilled water to remove possible impurities on the surface.

• Moisture regulation : The film can be soaked in distilled water or other suitable liquid as needed to adjust its moisture content. The moist film is softer and suitable for specific applications such as medical dressings.

• Cutting and molding : The film can be cut and molded with scissors or laser cutting equipment. Be careful when operating to avoid damaging the film structure.

3. Instructions for use

• Medical uses :

oDressing : Bacterial cellulose films can be used in wound dressings, providing a good wound protection and healing environment When in use, cover the film directly on the wound and use medical tape to fix it if necessary..

oBiomaterials : In tissue engineering, bacterial cellulose films can be used as cell culture substrates or artificial skin .

• Food packaging :

oMilk film : Bacterial cellulose film can be used as natural plastic wrap to wrap food to extend the shelf life. When in use, cover the film directly over the food surface and press gently to ensure a fit.

o Food grade coating : The film can be used on the surface of fruits and vegetables as an edible coating that provides protective coating and extends storage time.

• Electronic devices :

oFlexible display : Bacterial cellulose films can be used to make flexible electronic devices, such as substrate materials for flexible displays. When using it, it is necessary to ensure that the surface of the film is smooth and free of bubbles or scratches.

4. Things to note

• Avoid damage : Although the film has high mechanical strength, it still requires care during operation to avoid scratching, tearing or puncture.

• Chemical stability : Try to avoid contacting films with corrosive chemicals such as strong acids and alkalis to avoid material performance being affected.

• Biodegradability : Bacterial cellulose films are biodegradable. If they are no longer used, it is recommended to treat them in an environmentally friendly manner.

5. Processing and recycling

• Environmental treatment : The film can be treated by biodegradation, suitable for compost or industrial-grade biodegradation processes.

• Reuse : Uncontaminated films can be cleaned and reused, but attention should be paid to maintaining their physical properties and cleanliness.

Bacterial cellulose films may have special usage requirements in different application fields, and the specific operation and treatment methods should be adjusted according to actual needs.
