Traditional plastic packaging takes a long time to degrade in the environment and will produce a large amount of microplastics, causing long-term pollution to the ecosystem. In contrast, PVA water-soluble packaging is an environmentally friendly material that can dissolve quickly in water, avoiding the harm of plastic waste to the environment. With the deepening of the concept of sustainable development, PVA water-soluble packaging is considered to be an important material to replace traditional plastic packaging, which will help promote the development of the green packaging industry.
