Some of the common questions in plastic packaging is What does the recycling number mean?, Is this bottle recyclable? and does this package contain BPA?
Plastic Recycling numbers what do they mean? The number inside the recycling logo on the bottom of the plastic package determines how the package can be recycled and also is a key to determine the type of plastic used in production. These are recognised world wide.
What is BPA?
BPA stands for bisphenol A. BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s.
BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as large water bottles. They may also be used in other consumer goods.
Some research has shown that BPA can seep into food or beverages from containers that are made with BPA. Exposure to BPA is a concern because of possible health effects of BPA on the brain, behavior and prostate gland of fetuses, infants and children.
The Food and Drug Administration (FDA) has said that BPA is safe at the very low levels that occur in some foods. This assessment is based on review of hundreds of studies.
