Businesses in this category make, process or supply plastic goods that do not fit more specific product groups.

Products may be made from rigid or flexible plastics and supplied as standard items or produced to a customer's design and specification. Typical services include injection moulding, extrusion, blow moulding, vacuum forming, fabrication and cutting, as well as finishing, assembly and customisation. Some businesses also help with product design, mould or tooling development, prototyping and selecting materials for a particular use. Customers may buy finished products, semi-finished plastic components or made-to-order parts in specified shapes, colours, thicknesses and quantities. Recycled or recyclable plastics may be available, depending on the material and application.
