Kaizen foam tool chest liners
If you need to organise and protect your tools, foam drawer liners are ideal.
Foam drawer liners are a type of foam insert used in tool chests and boxes. Often referred to as Kaizen foam, the inserts typically have a dark top layer with bright contrasting colour for the cutout recesses within the foam, indicating when an item is not in place. Each recess is also cut in the exact shape of the tool, significantly improving organisation and efficiency.
At GWP Protective, we have been creating bespoke, precisely engineered tool chest liners for over 25 years. Our expert designers digitise your tools, then create a foam drawer liner tailored to your exact needs. We also manufacture all foam liners at our in-house production site in the UK.

What our customers say...

Excellent service from quoting through to production. Happy to work to timelines outside of the norm and offer solutions we may have not considered.
Andy Ball | Managing Director | JE Group

GWP were very creative with regards to ideas for the foam inserts, whilst not dismissing our original thoughts. GWP were quick, responsive, patient, eager to help and incredibly tolerant of gaps in our knowledge. I would absolutely recommend GWP to other companies looking for a similar service.
Jane Gossling | Creative Director | 270 Vision

GWP Protective got us out of a bind a couple of years ago when a previous supplier was letting us down and have been providing excellent quality products to us ever since. They are always more than happy to assist with design recommendations, their prices have always been very competitive and lead times are very short.

FAQs
Does my business need foam drawer liners?
Foam drawer liners offer several benefits. Firstly, they protect the items kept within, providing cushioning and preventing them from colliding. Secondly – and perhaps more importantly – they help with much quicker identification and retrieval of specific tools, improving efficiency. They can also help identify missing tools more easily.
Do foam liners move around within the drawer?
If using DIY toolbox drawer liner foam, the chances are the overall size won’t exactly match your drawers, and the inserts may move around unless fixed with adhesive. However, using pre-cut, custom-sized foam drawer liners ensures there is no movement that could cause damage.
What material are foam drawer liners manufactured from?
Foam drawer liners are manufactured using Plastazote® polyethylene foam. This material is widely used because it is inert, does not stain or mark tools even with prolonged contact, provides cushioning protection, and is easily machined, making it cost-effective to convert.
Is it possible to have drawer liners in different colours?
It is possible to manufacture custom drawer liners in different colours to either match your business’s corporate colours or differentiate between sets of tools or parts. Using different layers of foam can also help identify when a specific tool is missing, as the different-coloured foam recesses are easy to see at a glance.
What is Kaizen foam?
Kaizen foam, or shadowboards, is the name given to tool control foam inserts that use layers of different-coloured foam to highlight when a specific tool or part is missing (a lighter foam layer beneath a darker one makes this visually obvious). They were originally developed to prevent foreign-object damage in aircraft engines, but are popular for tool chest liners and similar applications.
