Packaging Foam and Sponge.
Packaging foam and sponge become a technical requirement when standard cartons and void fill can no longer control transit risks such as impact, vibration, and compression. For heavier, fragile, or high‑value products, impact, vibration, compression, and repeat handling can all cause damage long before a product reaches its destination. In these cases, foam is not simply protective padding — it is a material‑led solution designed to manage transit stresses reliably.
At AS Rubber & Plastics, we specify, convert, and produce packaging foam and sponge solutions to suit your product, handling method, and transit environment.
Fully Custom Packaging Foam & Sponge
The performance of packaging material depends on how well material selection and design are aligned to the product and the conditions it will face in transit. Factors such as weight, centre of gravity, fragility, frequency of handling, and exposure to impact, vibration, or compression all influence how effectively foam controls movement and damage.
Here at AS Rubber & Plastics, we support material selection and specification before conversion, ensuring foam and sponge packaging is designed around your application. All solutions are custom converted to suit the product and handling requirements, whether for one‑off projects or repeat supply.
Choosing the Right Material for Transit Protection
Selecting the correct material is essential to protecting products consistently during transport. Different materials behave differently under load, impact, and long‑term use, which is why material suitability should be assessed early in the design process. We have published an article explaining the different types of foam packaging, which provides additional background on material options and typical applications.

Packaging designs requiring vibration control or mixed‑material protection
Technical data sheets and material guidance are available to support informed selection and specification.
Custom Inserts and Packaging Formats
Custom packaging can be supplied in a range of formats, depending on how products are packed, handled, and transported.
Packaging Inserts
Used to locate and protect products within boxes, cases, or crates, helping to prevent movement during handling and transit.
Edge and Corner Protection
Designed to protect vulnerable edges and corners from impact damage during handling, stacking, and transport.
End Caps
Applied to either end of a product to control axial movement and absorb shock during transit.
Transit Pads
Used to provide cushioning, separation, or load distribution for stacked, layered, or palletised products.
Layered or Multi‑Density Solutions
Specified where different levels of support or protection are required within a single packaging design, typically for higher‑risk applications.
Quality, Consistency, and Repeat Supply
Once a packaging foam or sponge solution has been specified, consistency is essential — particularly for repeat orders and ongoing production.
Here at AS Rubber & Plastics, we operate under an ISO 9001‑certified quality management system, supporting controlled processes and specification traceability so your sponge and foam packaging performs consistently from one batch to the next.
