If packaging is made up of one packaging material (steel, aluminium, paper, wood, plastic, glass), laminated or processed with a material other than the packaging material (e.g. glue, adhesive, ink), it can still be considered single-material packaging.
For example, HDPE packaging with a layer of ink and the use of glues weighing more than 5% of the total weight of the packaging will display the code for HDPE single-material packaging.
