What is the Plastic Resin identification codes?
I am damn sure that all of you guys have seen on the plastic products such as on bottle, containers, Jug, or on many other plastic products the tiny triangular arrow symbol (a number with arrow around) with a number, the number could be any between 1 to 7 based on the plastic material used to make a particular product and that is called SPI Resin identification code.
Resin identification codes were introduced by SPI in 1988. This chasing arrow or resin identification code indicates that the product is made of particular materials.
The triangular or chasing arrow symbol I mean resin identification code on the product means it can be recycled but not necessary that all products which consist of such symbols are recyclable.
These RIC symbols or SIP symbol presence indicate that a product or package is manufactured from a certain plastic resin type.
Who created or introduced resin identification code?
In 1988 the SPI (society of plastic industry) created a resin identification code to help recycler to identify different types of plastics.
Resin identification code purpose?
Resin identification codes or plastic chasing arrow symbols were created because it’s easier to separate waste plastic products according to the material. This resin identification code concept was introduced to facilitate the post-consumer plastic recycling.
This plastic chasing arrow symbol or resin identification code makes it easier for recyclers as well as the separation of waste plastic products according to its resin code or material. “This resin identification code indicates the type of plastic that product is made from”.

Frequently asked questions
What does a resin identification code tell you?
This codes tells that which plastic material used to make the particular plastic product it could any number from 0 to 7, depend upon the product.
Are resin identification codes required?
Yes, of course. Because this days increasing the usage of plastic which means it’s also generates the waste which goes to trash but there are several types of plastics that can be recyclable so this codes makes easier in separation process of plastic waste meanwhile the recycling process.
