Water-soluble film, typically made from polyvinyl alcohol (PVAIt is made from materials such as... and is characterized by its ability to dissolve rapidly in water at specific temperatures, releasing the contents. This packaging form eliminates the need for unwrapping—simply place it directly into water—reducing the use of plastic packaging, making it convenient and environmentally friendly. However, the stability of water-soluble films is highly dependent on their contents.pHThe impact of value.PVAThe film is most stable under neutral or weakly alkaline conditions. If the cleaning product formulation is strongly alkaline (such as some drain cleaners) or strongly acidic (such as toilet bowl cleaners), it may accelerate the dissolution of the water-soluble film, leading to packaging damage during storage. Therefore, products packaged with water-soluble films must have formulations that...pHIt needs to be precisely controlled within an appropriate range.

During the cleaning process,pHValue and surfactant synergize. For instance, in the case of oily stains, alkaline conditions (pH > 7It helps to saponify oils, producing water-soluble fatty acid salts that break down heavy grease. At this point, pairing it with highly alkali-resistant surfactants (such as short-chain alkyl polyglucosides) can further emulsify the residual oil after saponification, achieving deep cleaning. Research reports indicate that certain surfactants remain stable even in high-temperature, strongly alkaline environments and effectively reduce the surface tension of the solution, enhancing penetration and emulsification effects.

This kind "Material (Water-soluble film)—Recipe (pH(with surfactants)—Performance (Cleaning Efficiency)" This collaboration exemplifies the shift of household cleaning products toward eco-friendliness and precision. By designing neutral or weakly alkaline formulas compatible with water-soluble films and selecting highly effective, readily biodegradable surfactants, companies can not only deliver powerful cleaning products but also contribute to plastic packaging reduction and carbon footprint minimization. This approach aligns with global carbon reduction initiatives while offering environmentally conscious consumers superior choices.
