Banana Fiber Paper Packaging shows a sustainable revolution in eco-friendly materials by utilizing a stem of banana plant. This innovative packaging solution offers biodegradability and strength while reducing environmental impact.
Its natural appearance and versatility make it suitable for a variety of packaging applications from food containers to luxury gift packaging.
Introduction
Bananas are widely grown in tropical and subtropical regions with the global production of 179 million tonnes annually.
After collecting fruits from a banana plant, it is often cut down, as the plant does not bear fruit again.
Unfortunately, we are discarding this banana plant waste in the environment for decomposition without knowing its full potential, where it releases methane gas, contributing to global warming and climate change.
In reality, stems of the banana plant contain abundant cellulosic fibers.
So, instead of discarding these natural fibers, we can convert them into biodegradable and eco-friendly packaging materials, such as paper, fabric and bioplastic.
In this blog post, we will discuss how paper is made, its benefits, disadvantages, potential applications and more.
What is Banana Fiber Packaging?
Banana Fiber Paper Packaging is an eco-friendly packaging solution made from fibers extracted from the pseudostem of the banana plant.
This biodegradable and sustainable material can replace traditional plastic and paper packaging, offering a more environment friendly alternative for various applications such as food packaging, gift wrapping and stationery.
How to Make Banana Paper?
Abundant soft cellulosic fibers are found in the inner core of the banana stem and transforming these banana fibers into paper involves different stages from fiber extraction to paper formation.
Let’s look at every step in detail for better understanding.
Step 1: Harvesting the Banana Plant Fibers
After getting fruit, stems of the banana plant are cut down. These stems are rich in cellulosic fiber, which is the primary component for paper manufacturing.
Stems are cleaned to remove dirt and insects or peeled off the outer layer to get the inner core of plant which has soft and flexible fibers.
Step 2: Extraction of the Banana Fibers
Once the pseudostem is harvested, the next step is to extract the fibers. There are a few methods to separate banana fibers from the waste plant materials.
Mechanical Extraction (Decortication)
Using a sharp tool or a decorticator machine, the pseudostem is peeled off to get the soft, long and flexible fibers from fleshy material.
You can also extract these plant fibers manually with the help of a knife, but it takes time.
A machine can quickly scrape out these fibers. However, care must be taken to avoid damage to the soft fibers.
Water Retting
In this method, banana strips are soaked in water bodies for at least 10-14 days.
Through the biological reaction, bacteria started to consume lignin and pectin which hold the fibers together, thereby loosening the fiberous materials.
Water retting can produce much better fiber qualities, but it is slow and can produce odour forming fibers because of fermentation.
Chemical Retting
In this accelerated method, chemicals (often alkaline) are used to dissolve the non-fibrous components of the pseudostem, such as cellulose, lignin, pectin, ash, protein and fats.
For example, soaking the banana fiber in a dilute sodium hydroxide (NaOH) solution can break down lignin and pectin much faster than water alone.
This method drastically cuts down the retting time to hours or a couple of days, unlike water retting which takes 10-14 days.
However, it must be done carefully since harsh chemicals can weaken the fibers and reduce their natural strength and flexibility.
After the extraction, fibers must be washed properly with water to remove dirt, decomposed matter or chemical traces followed by proper drying since damp fibers can develop mold or bacteria.
Step 3: Preparation of the Banana Pulp
After cleaning and drying the banana fibers, the next step is pulp preparation.
Cut the Fibers: Cut the banana fibers into smaller pieces (roughly 1–2 inches in length).
Soak the Fibers: Place the cut fibers in a large pot of water and soak them for few hours.
Cook the Fibers: After soaking, boil the fibers in water for around 2 hours (you can add a pinch of washing soda or mild alkali).
Boil the banana fibers for a couple of hours to dissolve remaining lignin and pectin that still hold them together.
As a result, clean water becomes brown in colour, which is called black liquor.
Rinse and Remove Black Liquor: Once cooking is done, carefully remove the black liquor from the pot.
The fibers at this point should be very soft and starting to separate into a fibrous pulp.
Rinse the cooked fibers again with fresh water to remove traces of the black liquor.
Blend or Beat into Pulp: Now, take these cleaned fibers and mechanically pulp them. For small batches, you can use a kitchen blender.
Blend the fibers with plenty of water until you get a mushy, uniform pulp.
The goal is to separate the fibers into a slurry.
(Tip: If you are blending with a kitchen blender then do it in batches and add sufficient water to avoid clogging the blades.)
If you plan to include additives for strength or texture, this is a good stage to mix them, for instance, you can add a tablespoon of natural starch (like tapioca or rice starch) to improve the properties of the resulting paper.
You can also mix recycled paper pulp if you want to experiment with texture or reduce the coarseness of banana fiber.
Step 4: Creating the Paper Sheets
By utilizing a mould and deckle, you can create a handmade paper sheet.
Prepare the Vat: Place the diluted banana fiber pulp into a wide-mouth tub.
The ratio of pulp to water in this tub or vat will determine the thickness (grammage) of the paper, for example, more water will give thinner paper, while less water gives thicker paper.
Submerge the Mould and Deckle: A mould is a wooden frame with wire netting and a deckle is a frame (without wire netting or screen) that sits on top of the mould to shape the paper edges.
Hold the mould and deckle together and dip them into the pulp tub horizontally.
Form the Sheet: While the mould is submerged, gently shake it side-to-side and front-to-back. This motion helps the fibers to settle down evenly across the screen.
Slowly lift the mold and deckle out of the tub.
You will see a layer of wet pulp distributed on the screen after removing excess water back into the tub.
Remove the deckle carefully from the mould to get a wet sheet of paper pulp.
Drain and Couch: If the mould’s screen is small, you can flip it on to the absorbent cloth. This process is called couching.
At this stage, much of the water is still in the wet paper sheet. So, use a sponge or soft cloth to remove excess water from the wet paper sheet.
Step 5: Pressing and Drying the Paper
To get strong and flat banana paper, it is important to remove water from pulp sheet, slowly.
You can sandwich the pulp sheet between two such absorbent cloths. Then apply pressure evenly across the pulp sheet to absorb water.
This procedure can be done by placing a heavy weight on top of the pulp sheet.
This step helps prevent warping of the paper.
Air Drying: After pressing wet paper, carefully remove the top cloth and allow it to dry slowly on a smooth surface. It will take a few hours up to a day, depending on the thickness of the paper.
Tips: Avoid rapid sun drying at this stage, as it can cause the paper to curl.
Step 6: Finishing the Banana Paper
Once the banana paper sheets are completely dry, they are ready for final touches to improve the paper’s appearance, texture and durability.
Smoothing (Calendaring): Handmade papers are rough in texture. To make it smooth, roll the paper between hard and smooth surfaces.
Trimming: Cut the edges of the paper by scissors or a paper cutter.
Adding Colour: You can add natural colour or dye at the pulping stage. Here are the commonly used colour pigments, such as turmeric (yellow), beet juice (pinkish purple), spirulina or spinach (green) or tea/coffee for brown tones.
Texture and Inclusions: Other natural fibers, such as bamboo fiber, cotton fiber or recycled paper fiber can also be added to the pulp to get a unique texture.
Adding seeds to the pulp will create seed-embedded paper that can sprout new plants on disposal. However, it should be added to the vat right before forming of the paper sheets to distribute them evenly.
Strength Additives: For extra strength, some manufacturers add a bit of starch or natural glue into the pulp.
Coating for Durability: A thin coat of natural wax or resin can be applied to make the paper more water-resistant if needed.
For instance, rubbing a dried sheet with beeswax or dipping it quickly in melted soy wax will impart some water-resistance quality.
After all these steps, your banana paper is ready to use!
You have turned agricultural waste into a functional and sustainable product.
How to Ensure the Quality of Banana Fiber Paper?
