Polyvinyl Alcohol Water Soluble Film for Packaging: Benefits and Drawbacks


Polyvinyl alcohol water soluble film is a type of packaging material that has gained increased attention in recent years due to its unique properties. In this article, we will discuss the benefits and drawbacks of using polyvinyl alcohol water soluble film in packaging.
Benefits of Polyvinyl Alcohol Water Soluble Film
Environmental sustainability: One of the key benefits of polyvinyl alcohol water soluble film is its environmental sustainability. Unlike traditional plastic films, which can take hundreds of years to degrade, polyvinyl alcohol water soluble film dissolves in water within minutes, leaving no harmful residues behind.
Increased safety: Polyvinyl alcohol water soluble film is also considered safer than traditional plastic films because it does not release harmful chemicals into the environment during degradation.
Versatility: Polyvinyl alcohol water soluble film is extremely versatile and can be used to package a variety of products, including food items, pharmaceuticals, and industrial goods.
Convenience: Another advantage of polyvinyl alcohol water soluble film is its convenience. With the ability to dissolve quickly in water, it eliminates the need for manual removal, reducing labor costs and increasing efficiency.
Drawbacks of Polyvinyl Alcohol Water Soluble Film
Limited shelf life: Polyvinyl alcohol water soluble film has a shorter shelf life compared to traditional plastic films. It is more susceptible to moisture, and may be prone to breakdown or loss of integrity over time.
Lower resistance to temperature changes: Polyvinyl alcohol water soluble film tends to have a lower resistance to temperature changes, and may not be suitable for use in extreme hot or cold conditions.
Higher cost: The production cost of polyvinyl alcohol water soluble film is currently higher than that of traditional plastic films, which may limit its adoption by some manufacturers.
Thermal stability concerns: Some studies have suggested that polyvinyl alcohol water soluble film may not be thermally stable, and may release harmful gases when exposed to high temperatures.
In conclusion, the use of polyvinyl alcohol water soluble film in packaging has both benefits and drawbacks. While it offers significant environmental benefits and convenience, it also has limitations such as a shorter shelf life and higher production cost. As the demand for sustainable packaging solutions continues to grow, it is likely that further research and development will lead to improvements in the performance and cost-effectiveness of polyvinyl alcohol water soluble film.
