Custom heavy duty packaging
Heavy-duty packaging is your best option if you require the highest level of protection for your products or components during transit.
Typically using double or triple-wall cardboard, your heavy-duty packaging can also include additional materials, such as timber, foam, and barrier films, to ensure it provides the optimum level of protection during handling and transit. Many engineering and manufacturing businesses use heavy-duty packaging for bulky, high-value, and fragile products, parts, and equipment.
At GWP, we design and manufacture custom, heavy-duty packaging that is precisely tailored to your requirements. This approach ensures you get the most cost-effective and sustainable solution, alongside maintaining your packs’ performance through the supply chain.

What our customers say...

We knew that GWP had assisted a number of similar organisations, so when we required packaging, we decided to reach out to them. GWP immediately indicated that they could help, and we took delivery of the boxes very quickly. They are absolutely perfect for safely packing the items we ship across the globe and maximising the available space in our shipping containers.

We had issues with a previous supplier regarding delivery and quality and so looked to GWP to provide better. They supply us with bespoke corrugated packaging for vending and dispensing equipment, protecting high value products. GWP is without a doubt one of our best suppliers.
Martin Stone | Production Manager | Autonumis

Great company to work with, very helpful and friendly. We needed a custom box designed and GWP produced the initial sample prototypes within 2 weeks from our initial meeting. Production volume order arrived to spec and ahead of schedule. Will use again.

FAQs
What is heavy-duty packaging?
Heavy-duty packaging refers to any form of cardboard packaging used for safely transporting heavy, bulky, or expensive items. It typically uses a double- or triple-wall corrugated material but can also incorporate wood, foam, films, and pallets. Heavy-duty packaging using multiple materials is known as composite packaging.
What materials does heavy-duty packaging use?
Heavy-duty packaging typically uses a double or triple-wall cardboard material. However, adding foam, timber frames, wooden pallets, barrier films, bags and even specialist coatings to heavy-duty packaging can provide specific levels of protection and performance.
What does double wall and triple wall mean?
Heavy-duty cardboard is usually double-wall or triple-wall. These materials utilise two (double-wall) or three (triple-wall) layers of corrugated paper in their construction, providing increased strength compared to single-wall material.
What makes cardboard heavy duty?
Most double or triple-walled cardboard (i.e., has more than one layer of fluting) is deemed heavy duty. However, the weight (GSM) of the papers used in producing the corrugated board can also be varied to achieve different strengths.
What is the strongest type of cardboard?
Triple wall cardboard, such as Tri-Wall or Tri-Mite, is widely regarded as the strongest type of cardboard. It can provide strength and compression resistance similar to that of timber cases but is considerably lighter and easier to recycle.
