Printing on foam or polypropylene? Pros and cons of different materials


Choosing the right substrate is the first step toward high-quality printing. Whether it’s for retail graphics, trade shows, exhibitions, or indoor/outdoor communication, the visual appeal, durability, and practicality largely depend on the material used. Two of the most common options are foam (expanded PVC) and honeycomb polypropylene.

But what are the real differences? And which material is better suited to your application? In this guide, we explore the pros and cons of both—helping you choose the best option for your next project.

Foam: lightweight, low-cost, but less durable

Foam board is made of expanded PVC and is widely used for temporary promotional applications, countertop displays, and indoor signage. Key advantages include:
● Easy to cut and process
● Good flatness for direct UV printing
● Low cost

However, it also has several drawbacks:
● Fragility: prone to corner damage and bending
● Poor resistance to moisture and external elements
● Difficult to dispose of: it’s a non-recyclable plastic material

Foam is a good solution for short-term, low-budget projects in protected indoor environments.

Honeycomb polypropylene: versatile, durable, and sustainable

Honeycomb polypropylene, like Innepla’s IPRINTOTM, is a technical solution designed for more demanding projects. It offers several benefits:
● Greater mechanical strength, even in large formats
● Waterproof and washable
● Compatible with UV printing and customizable with decorative films
● 100% recyclable and mono-material—ideal for sustainable projects
● Suitable for both indoor and short-term outdoor use

It’s the perfect choice for displays, totems, stands, info panels, and modular structures that require durability and premium appearance—even in more challenging conditions.

Foam or polypropylene? It depends on your goal

If your project is temporary, budget-conscious, and for indoor use, foam can still be a good choice.
But if you need a sturdier, reusable, and eco-friendly material, honeycomb polypropylene is the winning solution. With the IPRINTOTM line, Innepla offers versatile substrates for printing and displays—perfect for those seeking a balance of design, durability, and sustainability.
