Stratocell® Plus

Stratocell® Plus is a unique composite material that combines standard Stratocell® polyethylene foam with a laminated top layer.

Stratocell® Plus features a base layer of standard low-to-medium-density foam, heat-laminated to a high-density Cellu-Cushion® foam or a tough 3.5 mm polyethylene film. This structure means Stratocell® Plus offers significantly higher puncture resistance, minimal surface abrasion, and the ability to be “kiss-cut” to create durable, reusable hinges. It is selected over standard, unlaminated grades because it enables multi-component, flat-pack designs that can reduce storage space and labour costs (e.g., gluing multiple foam blocks together).

Our expertise at Polyformes means that not only do we supply and convert Stratocell® Plus, but we can also advise on whether this is the best option for your specific application. We’ll work closely with you to ensure you benefit from the optimal foam solution for your product, industry and budget.
