With a history of over 40 years, Williamson Manufacturing is a recognised supplier of quality plastic caps and dropper assemblies to the pharmaceutical and wholesale packaging industries in Australia , New Zealand and South East Asia . The steadfast commitment to quality and service to our customers has been an underlying principle contributing to the success of our business.

Our range of plastic caps include child resistant and “senior friendly” closures approved by the Therapeutic Goods Administration Australia. WILLSAFE™, WILLIAMSON 2000 SERIES and TAMPERDISC™ are our patented products.

We offer dropper assemblies of plastic stems with a choice of printed graduations and glass stems that include our popular bent range. We also offer options of child resistance or tamper-evidence.

By sourcing the best technology from around the world we aim to produce for the marketplace the highest possible quality products at a cost effective price.

From humble beginnings, the business has outgrown successive factories to be now located in a new purpose built factory and are proud to include leading pharmaceutical corporations in its customer base.
