Physically Cross-Linked Closed Cell IXPE 30 eFoam Packaging Inserts For Jewellery

Closed cell

Jewellery is a very personal item and can be both inexpensive and costly, but that doesn’t make it any less meaningful to an individual. When it comes to protecting jewellery in packaging, especially at the higher end of the spectrum with more extravagant items, it’s important to keep the craftsmanship of occasion wear preserved. It’s essential to secure jewellery items in place without them slipping around easily or becoming loose and amassing damage.

We recently worked with a high end jeweller who needed to keep their light-weight chain jewellery protected for transit during the gifting period. We advised the use of our closed cell cross-linked polyethylene foam, with its smooth surface and well distributed, independent closed cell structure.

Benefits of our Closed Cell Cross-Linked IXPE Foam


The foam itself doesn’t let off any odor nor does it absorb smells. If the foam is being used for display purposes or for presenting to potential custom, retailers can be rest assured there will be no bad odors from the foam itself and men’s and women’s parfums won’t pass onto the foam either.

Mould and stain resistant

Our IXPE foam has been irradiated by a high energy electron beam, meaning the foam is protected and defends against the growth of mould and bacteria, as well as not transferring colour to the packaged product.

This makes the cross-linked polyethylene foam a favourable material for packaging inserts when it comes to precious items such as jewellery, which may be both displayed and stored for long periods of time. Our closed cell polyethylene foam is UV resistant, chemically inert and non-toxic.

Durable and shock absorbent

The independent, closed cell structure of our IXPE foam makes it especially compact and robust, which means that it doesn’t crumble or go brittle over time. It can withstand handling well and is shock absorbent, making it a choice material for transit.

High strength to weight ratio

Our eFoam is lightweight but incredibly strong to combat against any wear and tear. It’s especially good for transit, keeping delivery and shipping costs low due to its weight compared to other foams.

Colour and flocking

Whilst most jewellers stick to standard black, grey and white, our eFoam is available in a range of colours if something bespoke is needed. We’re also able to flock foam if a more velvety surface is favourable to add a touch more luxury to packaging inserts. Due to the foams consistent cell size and structure, it also makes for a much more aesthetically pleasing foam.

As foam is likely to be touched or in contact with items that will be worn against skin, we’ve ensured that our foam is entirely skin friendly and hypoallergenic.

Despite its high quality structure and material benefits, our closed cell cross-linked foam is very cost effective. We can split, saw, rout, die cut, water-jet cut, butt-weld, laminate, adhere, thermoform or compression mould all of our foams to create even the most complex shapes and sizes. As well as ensuring bespoke inserts within the foam for items such as business cards.
