Affordable, eco-friendly plastic cases
If you need to present samples or protect and organise your equipment, SPI cases are a great option.
SPI cases are lightweight injection-molded cases manufactured by Maxado. They are available in eight sizes and eight colours. They also feature an integral handle, twin catches, metal hinges and a lid-stay mechanism. Their polypropylene material makes them water-resistant, durable and long-lasting.
At GWP, we have extensive experience in supplying SPI cases and enhancing them by adding bespoke foam inserts that are a perfect fit for your products or equipment. You can also speak with our case experts to discuss your specific requirements and the full range of plastic cases available.
SPI case features
SPI cases boast several useful features, enhancing both their overall usability and aesthetic quality.
Twin catches
The two catches ensure SPI cases secure your equipment or samples. Catch colours can be mixed and matched in varying combinations.
Integral handle
The handle is integral to the case body, making it more comfortable to use, providing greater longevity and minimising unit cost.
Smooth branding area
SPI cases provide a large area to the front and rear that you can brand using digital, screen printing, or in-mould labelling.
Metal hinges
SPI cases feature metal hinges that are smoother to use and last longer than living hinge designs or plastic equivalents.
Lid stay mechanism
Also known as a “ladder hinge,” a removable wedge allows the case to remain open at 90 degrees, making it ideal for displaying product samples.
Moulded feet
The moulded feet allow SPI cases to stand vertically, even with contents inside, to assist handling and storage when not in use.
Eco material
SPI cases use an environmentally neutral polypropylene material, whilst they can also be recycled at the end of their life.
SPI case sizes
SPI cases are available in eight sizes, the smallest being 165 x 12 x 30 mm and the largest 530 x 385 x 120 mm. They range in weight from 0.113g to 1.6kg. All SPI cases are available in eight colours: black, white, grey, navy, blue, green, yellow, and red.

Official SPI case suppliers
If your business needs SPI cases or any product or sample case, GWP should undoubtedly be your first point of call.
Being independent allows us to offer you cases from virtually every case manufacturer in the UK and beyond (including WAG, Maxado Excellent, and Hofbauer). It also means you can get impartial, unbiased and trustworthy advice on the best option for your specific application.
GWP Protective is also one of the UK’s largest foam converters. This means that any case you source from us can be expertly enhanced with custom foam inserts. Buying your cases and foam together, rather than from separate suppliers, improves compatibility, fit, appearance and overall quality while also reducing costs.
An in-house design team will guide you through every step of the process, while an experienced and knowledgeable team of experts will help with everything else, including a wide array of branding options.
Add competitive pricing, no-obligation quotes, and a discernible focus on customer service, and you have a truly winning combination. Simply complete the contact foam, and we’ll do the rest.
What size SPI cases are available?
SPI cases are available in eight carefully selected sizes. The smallest is 165 x 120 x 30 mm (Swing), and the largest is 530 x 385 x 120 (Glide). Please note that these dimensions refer to the case interiors.
Are SPI cases available in brand colours?
SPI cases are available in eight standard colours: black, white, navy, yellow, blue, green, grey, and ruby (red). Custom colours are available, although subject to relatively high order volumes. It is also possible to coordinate or contrast the catch colours.
Can SPI cases be printed or branded?
The smooth exterior surfaces of the SPI cases make them perfect for adding logos, imagery, and information. In addition to digital and screen printing, you can also opt for in-mould labelling, whereby the graphics are moulded into the case during manufacture.
Can I add foam inserts to SPI cases?
SPI cases are perfect for use with custom foam inserts. GWP Protective can manufacture foam inlays that are a perfect fit for the chosen cases and the samples, tools or parts you are storing/transporting within them.
What is a ladder hinge?
One of the unique features of the SPI cases is the ladder hinge. This feature allows the cases to remain open at 90 degrees, making them perfect for displaying products or samples. Please note that you can remove this if required.
Can I buy a single SPI case?
GWP Protective typically supplies businesses and professionals with their case requirements. While we have no minimum order quantities—you can have a single case with foam inserts—buying in larger volumes significantly improves the price. For a one-off empty case (e.g., for a hobbyist), it may also be worth looking at specialist online retailers. If you are unsure, please ask.
SPI case alternatives
If SPI Cases are not exactly what you need, we can offer you the broadest range of alternative plastic cases from a single UK supplier.
