Why LatherLogic Uses Flexible Pouches Instead of Glass or Rigid Containers

A common question is why LatherLogic relies on flexible post-consumer recycled (PCR) pouches instead of glass bottles or rigid plastic cartridges inside the unit. The answer has less to do with engineering preferences and more to do with how people actually buy and use shower products today.

In the current market, most consumers purchase shampoo, conditioner, and body wash in rigid plastic bottles from stores or online. Very few people routinely purchase large PCR bulk pouches designed to decant into a separate container. If the LatherLogic unit required glass or rigid containers to be filled at home, many users would simply pour from conventional bottles into those containers. In other words, we would be adding an extra step and an extra container on top of the existing bottle-based system, without meaningfully reducing packaging waste.

By contrast, LatherLogic’s flexible PCR pouches are designed to serve as both the primary packaging and the integrated supply for the device. They connect directly into the unit, avoid an additional rigid “middle” container in the home, and use significantly less plastic per volume of product than conventional bottles. This approach reduces material use and logistics impacts while keeping the user experience as simple as inserting a new pouch.

At the same time, the LatherLogic hardware is intentionally designed with future adaptability in mind. The unit is built around a reservoir connection, so if markets and consumer habits shift toward bulk PCR solutions or standardized rigid cartridges, it would be straightforward to develop compatible rigid modules that fit into the existing system. The core design does not lock LatherLogic into one material forever; it prioritizes what is realistically most sustainable and scalable in the present, while leaving room for more advanced options as the broader packaging ecosystem evolves.
