Closures are required on all bottles, jars, sprays, and pumps and can be made of several materials. The most common closure materials are High-Density Polyethylene (HDPE) or PP.
There is also a range of closure types which includes screw caps, clip-on caps, and push caps. Some have a retaining collar, which is to ensure they remain on the bottle throughout the recycling process. Items with a diameter under 40mm are deemed non-recyclable. They are normally injection molded.
Other specific criteria for closures need to be considered. For child safety caps, also known as child-resistant closures (CRCs), there is a question on the component form. This relates to choking hazards and dictates that small caps should have holes to allow airflow in the case of swallowing so that airways are not restricted. The cap size should be developed so that it is too large to swallow.
The type of cap and if it is non-removable (in a set) affects the recycling statement, i.e. replace the cap and recycle.
