What does the SPI Code (number inside the recycle symbol) 7-OTHER Mean?
The SPI codes are used to indicate the type of plastic from which the article is made. At the time of their creation, codes one through six were developed, as the overwhelming majority of plastic packaging was made from one of six main resins. The code 7 was developed for articles made from plastics that did not fall in one of the 6 categories. Many new plastics have been invented, including NatureWorks® biopolymer, that fall under the 7 category.
