A first-of-its-kind flexible film.
Strong, versatile, and luxurious, TPSea Flex™ is elevating the standard for compostable material by incorporating a regenerative ingredient: seaweed.
Designed for distributors, this flexible film can be converted via existing plastic machinery into a plethora of standard and bespoke formats.
TPSea Flex™ is made in part with seaweed, an abundant marine crop that supports ocean ecosystems and thrives without need for arable land, fresh water, or pesticides. This film decomposes in home and backyard compost environments after use, returning nutrients to the soil.

FAQ
Why We Made It
Despite the existing bioplastics market, plastic alternatives made from corn, potato, sugarcane, and trees don't always fulfill their promises.
• Their inputs may be grown through resource-intensive systems of industrial agriculture.
• Their inputs may compete with global food demands.
• They may lack performance in certain applications.
• They may be "biodegradable," but unaccountable to decompose within specific timelines.
• They may lack performance in certain applications.
• They may be "biodegradable," but unaccountable to decompose within specific timelines.
There is a pressing need for alternatives that solve these shortcomings. We view seaweed as a solution.
