What our customers say...

I just wanted to say thank you for all your help. When the boxes arrived we were all thrilled with how they’ve turned out. The quality is incredible, and we love how everything came together. Thank you again! We’ll definitely be in touch if we have any future projects for these items.
Emily Gunn | Marketing Assistant | C3 Marketing

The pack has worked remarkably well. There was some concern that using corrugated alone would protect such a high-value and fragile item, but to date, we have had zero returns due to transit damage. GWP has done a great job.
Julie Aparicio | Graphics and Service Designer | Haberdashery

Using GWP’s expertise for this project was a no-brainer as they consistently supply our organisation with high-quality packaging solutions that meet our exact standards. Their service is outstanding—reliable, responsive, and consistently exceeding expectations. We couldn’t ask for a better packaging partner.

FAQs
What are box inserts?
Many businesses use box inserts within outer packaging for various reasons. Inserts can improve the protection of items during transportation, aid packing and unpacking, and improve the presentation of products upon opening.
What types of box inserts are there?
There are a range of box inserts available, including:
- Cardboard divider sets.
- Die cut fittings.
- Layer pads and slip sheets.
- Foam inserts and end-caps.
- Reusable Correx divider sets.
- Vacuum-formed trays.
- Insulated box liners (for chilled packaging).
Are packaging inserts recyclable?
Corrugated cardboard packaging inserts are easily recycled by end-users in UK kerbside bins (or in the appropriate waste streams by B2B customers). Correx inserts and most foams are also recyclable but typically require specialist facilities.
Are box inserts suitable for my products?
It is possible to design and manufacture box inserts that are perfectly tailored to a specific product or application. This approach, rather than using off-the-shelf options, significantly improves appearance and protective performance.
Are box inserts reusable?
Cardboard box inserts are generally for single-trip applications, although they can often be reused if easily collected. End users frequently retain foam and decorative inserts for ongoing storage and protection. Options such as Correx dividers and foam dunnage are ideal for multiple uses as part of a returnable supply chain.
