Recently, there has been a growing demand for eco-friendly alternatives to plastic. One promising option is a new type of crab shell bioplastic wrap made from waste grab shells and wood pulp. This new film is flexible, transparent, and can be used to wrap food like plastic wrap. It is also biodegradable and compostable, making it a more sustainable option for food packaging.

Crab Shell BioPlastic Wrap

The new crab shell bioplastic wrap is made by spraying alternating layers of chitin and cellulose fibres sourced from discarded crab shells and wood pulp, respectively, onto a polylactic acid (PLA) base. Chitin is a natural polymer that is found in the exoskeletons of insects and crustaceans. Cellulose is a natural polymer that is found in the cell walls of plants. PLA is a bio-based plastic that is made from renewable resources, such as corn starch.

The new plastic wrap has a number of advantages over traditional plastic wrap. It is made from renewable resources, is biodegradable and compostable, and does not release harmful toxins into the environment. It is also transparent, flexible, and odourless.

The main material that the new plastic wrap is compared to is PET or polyethylene terephthalate. It is one of the most common petroleum-based materials used in transparent packaging, such as vending machines and soft drink bottles. The material showed up to a 67 percent reduction in oxygen permeability compared to some forms of PET. This means that the new plastic wrap could, in theory, keep foods fresher for longer.

In addition to plastic film, PET plastic is used in a variety of applications, including:

• Bottles: PET is the most common material used for beverage bottles, such as water, soda, and juice. It is also used for some food packaging, such as salad dressing and oil bottles.
• Fibres: PET is used to make a variety of fibres, including polyester, which is used in clothing, carpets, and other textiles.
• Films: PET makes various films, including food packaging, insulation, and tapes.
• Other applications: PET is also used in various other applications, such as electronics, automotive parts, and construction materials.

The new plastic wrap is still in its early stages of development, but it can potentially be a major breakthrough in the fight against plastic pollution. As the technology continues to develop, it is likely to become more widely available and replace traditional plastic wrap in a number of applications.

Benefits of Using Crab Shell BioPlastic Wrap:

There are a number of benefits to using crab shell bioplastic wrap. These benefits include:

• It is made from renewable resources: Eco-friendly plastic wrap is made from renewable resources, such as crab shells and wood pulp. This means that it does not contribute to the depletion of fossil fuels.
• It is biodegradable and compostable: Eco-friendly plastic wrap is biodegradable and compostable. This means it will not harm the environment when disposed of.
• It does not release harmful toxins into the environment: Eco-friendly plastic wrap does not release harmful toxins into the environment as it decomposes. This means that it is safe for people and animals.

Challenges of Using Crab Shell BioPlastic Wrap:

There are a few challenges to using crab shell bioplastic wrap. These include:

• It is still in its early stages of development: Eco-friendly plastic wrap is still in its early stages of development. This means that it is not yet as widely available as traditional plastic wrap.
• It can be more expensive than traditional plastic wrap: Eco-friendly plastic wrap can be more expensive than traditional plastic wrap. This is because it is made from renewable resources and is biodegradable.

Overall, eco-friendly plastic wrap is a promising alternative to traditional plastic wrap. It is made from renewable resources, is biodegradable and compostable, and does not release harmful toxins into the environment. As the technology continues to develop, it is likely to become more widely available and to replace traditional plastic wrap in a number of applications.
