Standard resin-code form

Plastic resin identification

Plastic resin code 7 — OTHER

7 OTHER identifies Other plastics or multi-resin plastics outside codes 1–6. It does not by itself confirm that the item is accepted by a local recycling service.

At a glance

What this symbol means

The resin identification code identifies the predominant plastic resin family as Other plastics or multi-resin plastics outside codes 1–6. It is primarily a material-sorting code.

The resin number identifies polymer type. Local collection rules still determine whether the specific package or product is accepted.

Recognition

How to recognise it

Look for the number 7 with OTHER or O.
The mark does not identify one single polymer; accompanying letters may give more detail.

Typical applications

Where it commonly appears

polycarbonate and some bioplastics
multi-layer or mixed-resin packaging
durable plastic products

Practical decision

How to sort or dispose of it

Read any material abbreviation next to the code.
Check the exact item and local route; code 7 is not a single recycling stream.
Use composting only when the packaging carries a valid compostability instruction and the receiving facility accepts it.

Before disposal or return

Empty packaging.
Separate removable components when instructed.
Keep hazardous or electrical products in their specialist streams.

Avoid contamination

Common mistakes

Treating all code-7 plastics as identical.

Assuming “bioplastic” means home compostable.

Using the resin code as proof of recyclability.

Important limitation

What it does not mean

The triangular code is not a universal recycling approval, does not describe contamination, and does not tell you whether the local service accepts that product format.

Questions

Frequently asked questions

Does 7 OTHER mean the item is recyclable?

No. It identifies the resin. Collection, sorting capacity, contamination and end markets determine whether the exact item is accepted.

Why can two items with the same code have different instructions?

Shape, size, colour, additives, labels, food residue and whether the item is packaging can change how a local facility handles it.

Should I follow the number or the local disposal label?

Use the number to identify material, then follow the product-specific and local disposal instruction.
