Sinchies are made from plastic using a combination of PET, NY and PE. Our pouches are free from BPA, Phthalate and PVC. There are no chemical phthalates or bisphenol A (BPA) in PET plastic, and therefore PET plastic does not leach these substances. PET plastic is approved as safe for food and beverage contact by FDA and similar regulatory agencies throughout the world, and has been for more than 30 years. Our squeezy pouches are made from 100% food grade silicone. We are constantly looking at ways of being more sustainable and are working with our factories to always ensure there isn’t much waste by using full rolls of materials.
