“The important characteristics for film soap containers are twofold: only a single sheet must be dispensed; the packet must be protected from water ingress and wet hands,” said Wong. “The most difficult design challenge was to reliably release a single sheet from the container. We originally thought it was easy, as paper poses no problems, but we found that two or three pieces would dispense when simply changing the product from paper to soap-based films.”
Early designs and the mechanisms for dispensing also caused the film to tear and bend, even if one sheet could be released reliably.
“More than 10 design prototypes were made, all ending in failure for one reason or another,” said Wong. “Some container designs operated well, but were judged too large for convenience and easy handling. In the end, we finally came to the slide type design.”
Wong notes that film has always been a convenient and non-messy delivery system, making film formats ideal for travel, and other products—such as shampoos, deodorants and cosmetic creams—lend themselves to the format.
“Developing a film for any application requires extensive testing to ensure each component can be compatible with the film production, as well as all of the other components within the film, without degrading the end film properties,” said Wong.
