Available in custom sizes, with attached (i.e. hinged) or separate lids, and in a range of material thicknesses, we can manufacture a solid fibreboard box to the exact specifications that you require.

About fibreboard packaging boxes

Fibreboard boxes manufactured by GWP provide you with various benefits, primarily their strength and durability.

A range of material thicknesses are available, up to a maximum of 2150 microns in thickness, all of which are manufactured from high-quality Kraft and Chip linerboard. This quality and range of material grades allow us to tailor the strength and weight of the box to your specific product, application or requirements.

Besides the strength, you can also select from a range of box styles, including 0427 style boxes with hinged lids or 0300 style packs with removable lids. Strong stapled joints add further rigidity and durability to your boxes.

Regardless of your chosen style and material – for which an expert designer will be happy to assist if required – a stock holding of material at GWP allows you to specify your fibreboard boxes from very low quantities and to meet urgent requirements.

Besides this range of options, your fibreboard boxes can also be manufactured in accordance with Defence Standard 81-15. As a result, these boxes are ideal if you supply directly to the MOD. However, they are also suitable for small and heavy components and parts, particularly for storing and transporting screws, nails, nuts and bolts and similar metal fixings.

And finally, all fibreboard boxes we supply are fully recyclable and biodegradable.

What are fibreboard boxes?

Fibreboard boxes are a type of packaging manufactured using solid fibreboard material. This material is strong and durable yet lightweight and fully recyclable. Fibreboard boxes are ideal for small and heavy objects such as screws, bolts and similar metal fixings.

What is a 4G fibreboard box?

A 4G fibreboard box is suitable for shipping dangerous goods. The 4G references the appropriate UN standards and Dangerous Goods Regulations the packaging must meet.

What is the difference between fibreboard and cardboard?

The main difference between fibreboard and cardboard is the material composition. Fibreboard is effectively a single, solid layer of material. Cardboard, however, comprises multiple layers of paper, typically two flat outer liners and a corrugated layer in the centre.

What are Def Stans?

Def Stan is a shortened version of Defence Standards. Defence Standards are a collection of material standards developed by the UK Ministry of Defence. These standards include a range covering the packaging materials that must be used if supplied to the MOD.

Are fibreboard boxes strong?

Fibreboard boxes offer an excellent strength-to-weight ratio. As there is no corrugated layer (as per cardboard boxes), they also provide superior compression strength. As such, fibreboard boxes are popular for heavy items.

Custom fibreboard box pricing

Whilst GWP can supply standard packaging to meet specific requirements (such as Defence Standard 81-25), our general approach as a business is to provide you with the exact packaging you need. Benefits include custom sizes, specific material grades, bespoke design and the specific features you need.

Whilst this means your packaging performs significantly better than stock boxes and is more cost effective in the longer term, it makes publishing prices on this website impossible.
