The main source of demand for this product is the packaging industry, and by the end of the year 2023, 61% of the global market is expected to be available to the packaging industry. Store customers use 500 billion plastic bags per year, which is still rising.
At present, the global packaging market is $ 4.6 billion with these types of plastics. It is necessary to explain that the global average growth of this industry is projected to be 9.9% in the coming years, and its revenue is estimated at $ 6.17 billion for the year 2030. It should also be noted that the total biodegradation of polymers in the world was $ 410 billion in 2015.
The main reason of non-biodegradability of common plastics is the length of the polymer molecule and the strong bond between the monomers that make it difficult to decompose by particle physicists.

The term “biodegradable” means substances that are simply decomposed by the activity of living organisms to their constructive units and therefore do not remain in the environment.

In industrialized and advanced countries, less than 2% of food is spoiled between production and consumption, while in developing countries the amount of corrosive material is 30 to 50% due to food insufficiency. Maintaining the quality and nutritional value in the long run requires the use of high quality materials and the provision of appropriate conditions to minimize the level of food metabolism and corruption.
Protecting the product and maintaining its quality is the goal of packaging food, so the packaging material should not change the quality of the food. Immigration, absorption and influence of the interactions are actions that may occur between the product and the packaging material.
In the phenomenon of migration, combinations of the packaging surface enter the product and make changes. Plastic bags and bottles is one of the most demanding types of packaging in the field of migration due to the presence of materials abundant additive.
PVOH film has the lowest permeability rate against oxygen and carbon dioxide among regular plastic films. It is a good barrier material.
The absorption phenomenon involves the absorption of food ingredients by the material packed. In this process, the food flavoring materials may be absorbed into the material and, as a result, the quality of the food will drop. In the process of penetration, some of the surrounding gases penetrate the packaging material, and then cause the quality of compounds to escape the important food factors, such as flavor or odor. Therefore, the non-permeability or low permeability of packaging material relative to gases has a great advantage in preserving the quality of matter Food is considered.
Generally, there are two types of biodegradable plastics:
One type is a mixture of natural and synthetic plastics (artificial), such as the production of films made from a mixture of starch and polyethylene, which after a while are discarded, destroyed and degraded. Our team of researchers works on both types of biodegradable plastics.
Researchers have produced a film that is being destroyed after a while by mixing starch and polyethylene (natural and synthetic polymers). Since this type of packaging film is not destroyed, researchers have focused on making sheets and edible films, which is destroyed 100%. These types of packaging are converted to microbes, bacteria and enzymes present on the soil or in the vicinity of sunlight to water and carbon dioxide and are destroyed.
