Cross-Linked PE (XLPE)
Cross-linking gives polyethylene a finer, tighter cell structure — and that changes what the foam can touch. XLPE's smooth, low-particulate surface won't mar painted or polished parts, cuts to crisp cavity walls, and presents products the way premium kits demand.
It's the step-up material for medical device trays, class-A automotive surfaces, and case inserts where the foam is part of the product experience.

Frequently asked questions
When is XLPE worth the premium over PE?
When the foam touches surfaces that can't be marked, when cavity cosmetics matter, or when particulate is a concern. For hidden industrial cushioning, standard PE does the job for less.
Can XLPE be laminated in colors?
Yes — multi-color laminated builds (e.g., black over gray) are common for tool control and presentation inserts.
