Whether you’re fitting a door frame, levelling a window, or aligning kitchen cabinets, precision matters. Enter the unsung hero of the trade world: plastic packers. If you’re still using bits of timber or scraps of cardboard to make things level, it’s time to upgrade.

Let’s break down what packers and shims are, why they’re better than traditional methods, and how they can save you time, money, and headaches on-site.

What Are Plastic Packers?

Plastic packers (also known as shims) are flat, solid inserts made from durable plastic used to level, space, or align components in construction and joinery. They come in a variety of sizes, thicknesses and are often colour-coded by size, making them easy to identify and use quickly.

Where Are Packers and Shims Used?

Plastic packers are incredibly versatile. Common uses include:

• Window and Door Installation – Ensuring perfect alignment and preventing future warping.
• Flooring and Decking – Creating even surfaces and correcting minor height differences.
• Kitchen and Bathroom Fitting – Levelling cabinets, countertops, and appliances.
• Partition Walls & Cladding – Providing accurate spacing between fixings or panels.
• Glazing Systems – Supporting glass panels safely and evenly.

Basically, anywhere alignment, spacing or load distribution is key, plastic packers are the ultimate solution.

Why Use Plastic Packers Instead of Timber or Cardboard?

Traditionally, many trades use wood offcuts, folded paper, or even coins to shim things into place. Here’s why packers are better in every way:

1. Consistent thickness: Each packer is manufactured to precise tolerances (no guesswork or uneven results).
2. Weather-resistant: Unlike timber or card, packers won’t swell, rot, or degrade over time. They’re ideal for both indoor and outdoor use.
3. High load capacity: Plastic packers are engineered to handle weight without compressing or breaking down under pressure.
4. Colour coded sizes: No need to measure on-site – simply grab the right colour and go for smarter, faster working.
5. Clean and professional: Packers give your work a clean finish and can even be left in place permanently without compromising integrity.
