Gemini is a UK plastic bottle manufacturer, producing custom bottles in our own Buckinghamshire facilities. Bottles are blow moulded from your own tool, with tooling, moulding and finishing on one site so a part goes from tool to finished bottle without leaving Gemini.
Why Gemini
Custom vs Stock
A stock bottle asks you to fit your product to someone else's shape. A custom bottle is made from your own tool, so the form, neck finish and detail are yours.
From first enquiry to final batch, you deal with one accountable UK team. Here's how it works.
Share your drawings, specifications, or simply an idea, whatever stage you're at.
Our team reviews your requirements and comes straight back with any questions.
Clear pricing and realistic lead times, with no obligation to proceed.
