PRIOR ART

Plastic sacks, bags or pouches are products obtained from thin and flexible plastic films, nonwoven fabrics or plastic textile products. Said sacks or pouches are used to transport and store goods such as food, product, powder, ice, magazines, chemical substances and waste products.

In the relevant technical field, it is common to use plastic and similar products as pouches or sacks for reasons such as low unit production costs, easy accessibility of raw materials, and simple and continuous production processes. For such reasons, it is more attractive to use plastic and similar raw materials in the production of pouches or sacks compared to paper or other textile products.

For the production of plastic bags, petroleum-derived polyethylene and similar raw materials are generally used. The products containing said raw materials threaten the environment and human health to a great extent. While the time required for these products to degrade in nature is 400 years in the seas, this period is 800 years on land. During this degradation, all harmful materials pass into the soil and water. In the terrains where people work, this situation also affects the products and causes the emergence of harmful situations. At the same time, plastic bags left to nature cause animals to die as a result of mistaking them for food, trying to consume them and disrupting their digestive systems. Plastic bags, which turn into more toxic and small petro-polymers with the effect of light, cause long-lasting situations that affect not only a single generation, but also the food chain for a very long time. It is known that especially black plastic bags are much more harmful because they are obtained from garbage. Black bags are offered to consumers after materials such as buckets, plastic bottles and medical waste are separated from the garbage and painted black to hide their defects. Apart from these obtained materials, the use of only black dye is the reason for restricting the use of these bags. The gases released during the disposal of plastic bags cause damage to the environment at least as much as the use of bags. Even plastic bags are among the causes of sudden forest fires. The transparent ones of these bags, which are thrown into the environment, absorb heat by making a greenhouse effect and cause forest fires.

In the related technical field, studies are carried out to reduce the use of plastic and similar products as raw materials for the production of bags or pouches due to the mentioned disadvantages. There are many studies in the literature for this purpose. The invention with patent number US5948848 A, which is one of these studies, relates to a biodegradable plastic material and a method for the production thereof. The present invention provides a method of producing a biodegradable plastic material comprising mixing a partially hydrolyzed, water-soluble polyvinyl alcohol (PVA) copolymer with a plasticizer and stabilizer at a temperature between 106°C to 140°C. The resulting material can be easily processed by known processes and is suitable for the manufacture of water-soluble and biodegradable products.

The invention with patent number WO2016134094 A1 relates to bioplastic compositions containing starch, methods of making such compositions and methods of using these compositions as insulators, and more particularly bioplastic compositions containing a starch. The subject of the invention is a bioplastic composition comprising at least one starch, at least one plasticizer, and at least one acid, wherein the at least one starch is between 2% by weight and 25% by weight, at least one plasticizer is between 40% by weight and 65% by weight, and at least one acid is between 1% by weight to 10% by weight.

The invention with patent number W02014120417 A2 relates to the composition of a biodegradable bio-plastic material that makes it possible for consumable products to be green and is beneficial for the environment in several key areas.

As a result, it has become a necessity to carry out studies to reduce the use of plastic and similar products as raw materials in the relevant technical field. BRIEF DESCRIPTION OF THE INVENTION

Method 1. Obtaining a bag in which the water component is used as a solvent

As the main component, polyvinyl alcohol raw material is dissolved in water. The polyvinyl alcohol mentioned here is added in the range of 1% to 3% by weight in water and mixed for a while. The said process is carried out by mixing at room temperature or 50°C in a magnetic stirrer. Other components, starch, xanthan gum, psyllium powder, polyethylene glycol, water are mixed. Egg white and/or gelatin (dissolved in hot water) is added. Finally, the aqueous PVA solution is added to the resulting mixture. Then, after drying processes at room temperature, a thin film is obtained.

Method 2. Obtaining bags in which DMSO is used as solvent

It is obtained by dissolving the raw material of polyvinyl alcohol (PVA) as the main component in DMSO. PVA is added in the range of 1% to 3% by weight in DMSO (dimethyl sulfoxide) and stirred in a magnetic stirrer 45°C overnight. It is mixed with starch, xanthan gum, psyllium powder, polyethylene glycol, water. Egg white and/or gelatin (dissolved in hot water) is added. The PVA solution in DMSO is added to the resulting mixture. Then, it is poured on the glass, the thin film is obtained after drying processes by gradually increasing the temperature at a temperature in the range of 90 to 130°C.

Method 3. Obtaining water-based bags

As the main component, polyvinyl alcohol raw material is dissolved in water. The polyvinyl alcohol mentioned here is added in the range of 1% to 3% by weight in water and stirred at the room temperature or at 45°C in a magnetic stirrer for a while. Starch is mixed with vinegar, preferably 50-90°C temperature can be applied. Then, water is added to the mixture by mixing it with xanthan gum, psyllium powder, polyethylene glycol. Then, it is mixed by adding egg white, rubber and/or fig milk, sugar cane syrup. The PVA solution in water is added to the resulting mixture. Then, after drying processes at room temperature, a thin film is obtained.

It is possible to obtain bags consisting of components, which are biodegradable and do not have any toxic effects for human and environmental health by applying the process steps of Method 1 , Method 2 and Method 3 mentioned in the invention.

The bag of the invention is easily soluble in water. In order to delay its water solubility, the bag may contain water-retarding agents. Silicone gel dissolved in toluene, polyacrylic spray and/or pine turpentine oil can be used as the said water-retarding agent. Preferably, the water-retarding agent comprises silicone gel and toluene components. Preferably, it can be obtained as a mixture of silicone gel and toluene and can be obtained by brushing or spraying polyacrylic spray on the surface of the bag. The bag of the invention does not contain any components that will cause toxic effects for human and environmental health. In this aspect, it is possible to obtain degradable and environmentally friendly bags.
