The number represents the resin used in make the bottle and how easy the plastic bottle is recyclable.
1 = easiest to recycle (remake into other stuff like bottles).
7 = most difficult to recycle

Most plastic containers are stamped with that little triangle of arrows with a number inside it. The number refers only to the type of plastic resin used for that container. It does not mean that the container is accepted for recycling. These codes were developed by the Society for the Plastics Industry simply to identify resin types to processors.

A number inside a triangle tells you what type of plastic it is. Certain recycling facilities can only recycle certain types or numbers of plastic. It has nothing to do with how many bottles are made- only the type of plastic it is made from.

It's called a resin identification code, and it is used to indicate the type of plastic that an item is made from. In 1988 the plastics industry introduced its voluntary resin identification coding system. A growing number of communities were implementing recycling programs in an effort to decrease the volume of waste subject to rising tipping fees at landfills. The code system was developed to meet recyclers' needs while providing manufacturers a consistent, uniform system that could apply nationwide. Because municipal recycling programs traditionally have targeted packaging – primarily bottles and containers – the resin coding system offered a means of identifying the resin content of bottles and containers commonly found in the residential waste stream.

it has to do with recycling. The number determines the material that the plastic is made from.A recyclable plastic container using this scheme is marked with a triangle with three "chasing arrows" inside of it, which enclose a number giving the plastic type: PETE, HDPE, PVC, LDPE, PP, PS, and OTHER (for more info seeplastic packaging resins)

This is the SPI number which helps recyclers identify the type of plastic and sort the bottles appropriately for recycling.

it is with the plastic content code.
this website contains a powerpoint about plastics and explains it in detail, including what the numbers mean, which can be recycled, and which actually are. only numbers 1 and 2 can be recycled for food packages, and few are, due to their shape.

The number signifies what type of material the item is. Different numbers are separated by the recycling company. Some jurisdictions only recycle certain numbers.

It indicates the type of plastic used so that when recylced different types of plastics are not used together...
i.e. all #7 plastic is a different thickness/composition than all #1plastic...it gets sorted when recycled...

It is the recycle code. It lets people know if that "number" is accepted at their local recycle center.
ours only accepts up to a certain number.
