Frequently Asked Questions

PP corrugated sheets are rigid yet lightweight sheets made from polypropylene with a twin-wall, fluted internal structure. This construction gives the material an excellent balance between stiffness, impact resistance and low weight.

PP corrugated sheets are widely used in applications where durability, reusability and moisture resistance are required, such as packaging, protection, signage and construction-related uses.

PP corrugated sheets are used across a broad range of industries. They are commonly applied in packaging and protection solutions, including returnable packaging and protective components. They are also widely used for signage and display applications due to their printability and ease of handling. In addition, PP corrugated sheets are used for construction and industrial protection, where robustness and reusability are key requirements.

PP corrugated sheets offer several advantages compared to cardboard, especially in demanding or reusable applications. They are resistant to moisture and humidity, maintain their mechanical properties over multiple use cycles and are more durable in handling and transport environments. For returnable or long-life applications, this often results in a lower total cost of ownership and reduced material waste over time.

In the market, terms such as Correx or AkyLux are often used to describe twin-wall or corrugated polypropylene sheets, rather than a specific technical specification. While these names originate from registered brands, they are commonly used as shorthand for the material category itself.

At Distriplast, we manufacture polypropylene corrugated sheets under our own brand, Diplast®, and focus on solutions defined by performance, application requirements and sustainability objectives rather than by brand terminology.

Yes - depending on the application, you can specify properties such as UV resistance to improve outdoor performance.

PP corrugated sheets are available in a wide range of thicknesses, weights and dimensions, depending on the intended application.

Rather than selecting a standard product, most projects benefit from defining a specification based on performance needs such as stiffness, load resistance, handling conditions and reuse cycles. To explore typical specifications and use cases in more detail, we invite you to consult our different application pages.

Distriplast supports customers in translating these requirements into the most appropriate sheet specification.

Yes. Depending on the application, PP corrugated sheets can be produced with additional functional properties, such as improved UV resistance for outdoor use, antistatic behaviour, flame-retardant performance or specific surface characteristics. The feasibility of these options depends on regulatory requirements, performance targets and end-use conditions, which are assessed together with the customer.

PP corrugated sheets are commonly used in signage and display applications and can be suitable for printing when the appropriate grade and surface treatment are selected. Printability depends on factors such as ink system, printing method and durability requirements.

Distriplast helps customers choose the right solution to balance visual quality and functional performance.

The most effective way to specify a PP corrugated sheet is to start from the application rather than from a material name. Factors such as indoor or outdoor use, mechanical requirements, expected reuse cycles, printing needs and converting processes all influence the optimal specification. Based on this information, Distriplast can recommend a tailored solution that meets both technical and sustainability objectives.

Polypropylene is a fully recyclable material, and PP corrugated sheets are designed to support recycling at the end of their life cycle. After use, they can be collected and reprocessed into new polypropylene-based products, making them well suited for circular economy models and reusable packaging systems.

Yes. Distriplast offers PP corrugated solutions with recycled content, depending on application requirements and performance expectations. The use of recycled material helps reduce environmental impact while maintaining the functional properties required for industrial, packaging and protection applications.

Distriplast actively supports customers who require sustainability documentation, such as life cycle assessments or environmental product declarations, where available. This support is particularly relevant for customers operating in regulated markets or with corporate sustainability and reporting obligations. Visit our Certifications page for more information.

Distriplast goes beyond supplying standard sheets. Depending on the project, the company supports customised PP corrugated solutions that are adapted to specific applications. This can include cut-to-size sheets or converted components that integrate directly into packaging, protection or display systems. Contact our sales team for more information.

Yes. Distriplast works closely with customers to understand their product, handling conditions and logistical constraints. Based on this insight, tailored solutions can be developed that optimise protection, usability, durability and sustainability throughout the product’s life cycle.

Distriplast is a European manufacturer and supplies customers across Europe, depending on order scope and logistical requirements. Delivery conditions and lead times are defined based on the project specifications, quantities and destination.
