Sarkixtia is a revolutionary packaging concept. A packaging concept made 100% of sargassum, an abundant pest well known in Mexico, which is converted into a highly fertile and sustainable material that fulfills its useful life in a completely circular cycle. Good for enterprises, which use packaging to protect their products, sargassum recollectors and environmentally conscious population. Our proposal brings a pest threat into a solution for the linear consumerism of today's packaging. It is a completely circular packaging as well as powerful fertilizer making it ecofriendly.
