A chasing-arrows triangle around the numeral 1, identifying PET.
The numeral 1 in a triangle of arrows identifies polyethylene terephthalate, the plastic used for drinks bottles. The code identifies the resin; it is not a claim that the item is recyclable.
Identifies polyethylene terephthalate under the resin identification coding system standardised as ASTM D7611.
Contexts: Packaging
Read as a recycling claim because of the arrows, which is the central misunderstanding of the whole system: the code states what the plastic is, not whether anyone will accept it.
Contexts: Packaging
Three arrows chasing one another around a triangular path, enclosing the numeral one at the centre.
The plain Mobius loop asserts recyclability; the resin code borrows its arrows to identify a plastic and asserts nothing about recycling.
Both are built from triangles, arrows and number like forms, and both are used in packaging contexts.
