Biodegradable bags that dissolve in water are usually made of water-soluble materials (PVOH or PVA) that break down or dissolve when exposed to water. These water-soluble biodegradable bags are different from traditional biodegradable plastics (such as those made from starch or PLA) because they are not only biodegradable but also soluble in water.

Product Features:

Water Solubility

This biodegradable bags that dissolve in water has the property of dissolving in water. When it comes into contact with water, it will gradually dissolve over a certain period of time. For example, in water at room temperature, it may completely dissolve in a few minutes to a few hours, depending on factors such as the material formula and thickness of the bag. Its dissolution process is a physical and chemical change in which the material molecules interact with the water molecules, causing the bag's structure to gradually disintegrate.

Biodegradability

Biodegradability is one of the core features of this biodegradable bags that dissolve in water. It can be decomposed by microorganisms in the natural environment. In the soil environment, there are various microorganisms, such as bacteria, fungi, etc., which can use the organic components in the bag as a carbon source and energy source. They break down the polymer structure of the bag by secreting specific enzymes, gradually degrading it into carbon dioxide, water and biomass.

Physical properties

Biodegradable bags that dissolve in water have a certain strength. Although it is soluble and biodegradable, it can withstand a certain weight and pressure during normal use. For example, for small bags (such as bags used to pack snacks or trinkets), it can withstand the weight of the items themselves and slight squeezing during transportation and storage without breaking easily. Its tensile strength can reach a certain standard to meet basic packaging needs.

Environmental advantages

Biodegradable bags that dissolve in water have a significant protective effect on marine ecosystems. Traditional plastic bags are one of the main sources of marine garbage. They will be mistakenly eaten by marine life, causing the death of marine life or damage to physiological functions. After entering the ocean, water-soluble biodegradable bags will gradually dissolve and degrade, greatly reducing the harm to marine life. For example, marine animals such as turtles often mistake plastic bags floating on the sea for jellyfish and swallow them, while biodegradable bags can avoid this from happening.

Advantages of convenience

Biodegradable bags that dissolve in water are very convenient to clean. For example, in a home kitchen, if you use a water-soluble bag to hold food scraps, when cleaning, just put the bag in the sink and it will dissolve. There is no need to take it out of the trash can like traditional garbage bags, which avoids the problems of garbage residues in the trash can causing odor and bacterial growth.

Safety advantages

Higher safety for food and drug packaging. As mentioned earlier, the material of this bag is non-toxic, and no harmful substances will migrate into the packaged food and medicine, ensuring the health of consumers. In the food industry, biodegradable bags that meet food safety standards can be used to package fresh food, baked goods and other types of food, providing consumers with safe and reliable food packaging solutions.
