What makes PlasticPackers different?
We focus on the details that matter when you’re fitting windows, doors, joinery or cladding—so you spend less time hunting for the right packer and more time getting the job finished properly.
Consistent sizing
Packers that are the size they claim to be, helping you keep installs level, square and repeatable.
Trade-first packs
Practical pack sizes and mixes for van stock, site work and trade counters.
Clear, honest pricing
Transparent pricing with no surprises at checkout, and better value on larger quantities.
What we stock
Our range is built around the sizes and formats fitters actually use on site—whether you’re packing glass, levelling frames, or shimming joinery.
Flat Glazing Packers
Core widths (20, 24, 28, 32 mm) in colour-coded thicknesses from 1–6 mm for everyday glazing and levelling work.
Bridge Packers
Designed to sit around fixings and screws, spreading load to reduce the risk of cracking or localised stress.
Frame Packers
Rigid shims for squaring and stabilising doors, windows and frames during installation.
Wedge Packers
Paired wedges for fine toe-and-heeling and final adjustments once hardware is fitted.
Mixed & Specialist
Van-friendly mixed sets and specialist sizes for less common profiles and applications.

How PlasticPackers came together
PlasticPackers.co.uk grew from a simple idea: make it easier for fitters to get the packers they rely on, without digging through generic catalogues.
- Step 1 — Focusing on packers
Starting with the core plastic packers used day in, day out on glazing and frame installs. - Step 2 — Refining the range
Listening to fitters and trade counters to refine widths, thicknesses and pack sizes. - Step 3 — Building a clearer shop
Creating a dedicated online shop where packers are easy to find, compare and re-order. - Step 4 — Supporting more applications
Expanding into frame, bridge and wedge packers, plus mixed sets and specialist sizes.
What installers say
