More info on Foam Inserts

Why use Plastazote® for your cut foam inserts?

Plastazote, the foam material of choice for GWP Protective, is unique in that provides both superb cushioning performance alongside high-quality appearance / presentation.

It is well known for being lightweight, tough, flexible, moisture resistant, chemically inert and resistant to oils, solvents, dilute acids, and UV light. It is also available in a large range of colours, meaning you can easily match your business’ branding or specific product ranges.

Besides this, specialist foams, such as conductive, static dissipative and high density are all available in the range.

Using this material, your engineered foam inserts are designed to reduce the effect of shock and vibration on any delicate, highly calibrated or valuable items during transportation and storage.

By using the latest software and performance models, GWP can accurately engineer the precise level of cushioning required for a specific product or item. In turn, by reducing the effect of any shocks generated by mishandling of the exterior case to a specific level of performance, it will allow damage to the packaged article to be greatly reduced (or in many cases, completely eradicated).

Plus, as GWP Protective are one of the largest independent UK suppliers of transit and equipment cases, your foam inserts can be designed to work seamlessly with any exterior case, container, or even cardboard packaging. This greater level of compatibility between case and foam allows for protection from vibration, water and dust as well as providing highly engineered, precise levels of cushioning.

Applications for foam inserts

Foam inserts are a surprisingly versatile and widely used for protection of products.

This includes everything from foam inserts for toolboxes that quickly help to identify missing kit, simple lining of containers and all the way through to extra tough moulded plastic cases with foam that provide exact levels of cushioning from mishandling.

Whatever your application, GWP Protective can help your business minimise the cost of expensive, fragile or specialist items becoming lost or damaged.

At the other end of the scale, the precise nature and high-quality finishes achieved during the advanced manufacturing techniques utilised, can make foam inserts an innovative and distinct way to differentiate your brand. This can allow for enhanced presentation of product samples in sales pitches, or even be used to assist sales in sectors where added value packaging is all important.

The bottom line is that whatever challenge your business faces, or project it is working on, GWP Protective foam inserts provide the versatility and performance to help.

Foam Insert FAQs

Frequently asked questions about custom foam inserts

Please see below for a list of common questions regarding the foam inserts that can be designed, manufactured and supplied by GWP Protective.

Can’t see the answer to your specific question? Please contact a member of the GWP team – on 01722 416 440 or – for further assistance.

What are foam inserts used for?

Although typically used for the purpose of cushioning tools, equipment or products within an outer case or packaging – which prevents damage in transit – foam inserts can be used for a wide range of additional applications. This includes aiding retrieval of items, presenting samples and even acting as part of luxury packaging.

Are foam inserts for use in boxes or cases?

Plastazote® foam inserts tend to be used with protective cases, including waterproof, aluminium, or custom-built options. They can also be used within sample presentation cases. Saying that, GWP Protective can provide a wide range of foam inserts for boxes – used with high volume corrugated packaging – as well as retail applications and even foam dunnage for use in returnable handling products.

What are foam inserts manufactured from?

The foam inserts that GWP manufacture are nearly always manufactured from Plastazote® (although for single trip applications where the outer packs are cardboard, Stratocell or Ethafoam is more likely to be used). This is due to the inherent properties of Plastazote® (providing excellent performance), its relatively low cost, the range of options and the high-quality appearance that can be achieved.

What colour foam inserts are available?

Plastazote® comes in a range of more than 20 colours, allowing for you to choose a shade that closely matches your company’s logo and / or branding. Please note however that not all colours are available across all grades. A GWP adviser will be happy to provide information on the options available and suitable for your specific application.

I’ve seen two tone foam inserts – how are these made?

Using layers of different coloured Plastazote® can create foam inserts with a unique and attractive appearance. This is most commonly seen with a black or dark foam laminated on top of a contrasting colour. When machined, the brighter colour underneath shows through to create a striking visual effect (which can also help with identifying missing parts or equipment too).

What is a shadow board?

A shadow board is where different coloured foams are layered on top of each other, with any recessed pockets being a different colour to the foam on top. Apart from looking great, this can actually help the identification of any parts not returned to their specific place within the case or toolbox, due to the area of brightly coloured foam being visible at a glance.

How can foam inserts protect my items?

The main way that foam inserts protect items during transit or any form of handling, is by providing cushioning within the outer case or packaging. Not only does this stop the contents colliding with each other, but also with the internal walls of the container. Taking this one step further, GWP Protective can calculate the exact levels of foam required to absorb specific levels of shock or impact – offering a truly bespoke (and optimised) level of protection for your items

How should I choose an exterior case for use with my inserts?

Besides foam inserts, GWP can also offer your business a wide range of exterior case options. For example, waterproof cases are ideal for heavy, rough-handling applications, whereas lightweight plastic sample cases are more suitable where handling will be more careful. Other options include metal, custom built flight cases, plastic tote containers and even cardboard boxes. A GWP team member will be happy to offer guidance on the best option for your business.

What are pick and pluck foam inserts?

Pick and pluck foam inserts are a type of foam that is already pre scored, typically into 1 cm cubes, which can be removed by the end user to create a semi bespoke insert. Typically supplied with waterproof cases such as Peli (or Storm, SKB or Nanuk etc.), these are a good choice for a one-off project (e.g. hobby equipment, camera cases and so on). For industrial applications however, GWP would always recommend custom Peli foam cutting / bespoke inserts.
