Have you ever stopped to think about what your period products are made of?
Most conventional pads are made with a surprising amount of petroleum-based plastic—in the wrapper, the leakproof backing, the absorbent layers, and even the adhesives. In fact, many disposable pads are made with up to 90% plastic, much of it derived from fossil fuels.
That matters because petroleum-based plastic is made from non-renewable resources and can take hundreds of years to break down.
At joni, we believe period care can be made differently.
We’re not here to claim perfection. But we are committed to reducing reliance on petroleum-based materials by thoughtfully choosing lower-impact ingredients that balance sustainability and performance.
Because better period care means making meaningful improvements without compromising on what people need from their products.
Why Plastic Is Used in Period Products
Plastic became common in disposable period care for one reason: it works.
It helps prevent leaks, improves absorbency, and keeps products durable and hygienic. These performance features matter—especially for something as personal and essential as period care.
The problem isn’t performance. The problem is that conventional plastic relies heavily on petroleum, a fossil fuel resource that contributes to long-term waste and environmental harm.
Thoughtfully Chosen Materials with Lower Impact
At joni, we choose materials that reduce environmental impact without compromising the performance people count on.
Our protective biofilm layers are made with a thoughtfully selected PBAT and PLA blend that is certified compostable by the Biodegradable Products Institute (BPI). PLA is made from renewable plant-based resources, while PBAT adds the flexibility and durability needed for reliable leak protection. Together, they create a high-performing barrier layer that helps reduce reliance on conventional petroleum-based plastics while supporting end-of-life compostability standards.
In the absorbent core, we use Sumitomo super absorbent polymer (SAP)—an industry-leading material trusted for its high performance and reliability. This advanced SAP quickly locks in fluid to provide dependable absorbency while allowing for a thinner, more comfortable product design. Sumitomo’s SAP technology is also used in agricultural applications to support water retention in soil, demonstrating the versatility and efficiency of this high-performing material.
By combining certified compostable plant-based films with premium absorbent technology, we’re able to create products that offer both comfort and performance with a lower environmental footprint.
Because creating lower-impact period care means choosing materials that are thoughtfully designed to perform better—for people and for the planet.
Progress Over Perfection
We believe sustainability is about progress, not perfection.
There is no perfect disposable period product. But there are better choices—products made with renewable ingredients where possible and more intentional design decisions.
That’s what low-impact disposable period care means to us:
-
reducing reliance on fossil-fuel-based plastics
-
increasing the use of renewable materials
-
designing for performance and comfort
-
continuously improving as better materials become available
This approach helps reduce environmental impact while still making period care accessible and effective for the people who rely on it.
Because not everyone can or wants to use reusable products—and more sustainable disposable options matter.
Better Choices, Real Impact
Every material choice adds up.
By reducing petroleum-based plastics and using lower-impact alternatives where possible, period care products can lessen dependence on fossil fuels while moving the industry toward more responsible design.
That may not be perfect—but it is progress.
And progress matters.
At joni, we’re committed to creating low-impact disposable period care that thoughtfully combines renewable materials, high performance, and radical transparency, because you deserve to know what’s in your period care—and why.
Because better products start with better choices.
