H-Line / S-Line comparison

H-Line / S-Line

Along flutes · strongAcross flutes · weak
H-Line and S-Line directional strength comparison H-Line has a large gap between strength along the flutes and across them. S-Line has greater transverse strength and a smaller gap between its two directions; the flute direction remains stronger. The bars show a schematic trend, not measured MPa values. Relative strength H-LineS-Line

S-Line offers a more balanced directional response.

Surface Treatments & Additives

Match the surface and functionality of your corrugated sheets to the way they are printed, handled and used.

Corona treatment

Increases surface energy to improve ink, coating and adhesive adhesion. The treatment level is tailored to your printing or bonding process.

Anti-slip

Grip-enhancing finishes help reduce sliding in separators, protective liners and handling applications. Surface friction is selected for the load and the materials in contact.

Anti-static

Helps reduce static charge build-up and dust attraction during handling. Electrical performance is specified to suit the components being packaged and their working environment.

Flame retardant

Formulations can help delay ignition and slow flame spread. Required fire performance is assessed for the selected sheet thickness, application and test classification.

UV treatment

UV stabilisation helps limit sunlight-driven ageing, colour change and loss of strength. The formulation is selected around exposure, climate and intended outdoor service life.

Anti-corrosive

Protection options help address corrosion risks for packaged metal parts. The suitable system depends on metal type, moisture exposure, storage duration and packaging design.

Options are specified by product and application. Our team can confirm availability, compatibility and the performance requirements for your project.

Comparison with different materials

Explore the practical differences between corrugated PP, cardboard and injection-moulded packaging.

Ten practical considerations for corrugated polypropylene, corrugated cardboard and injection-moulded plastic packaging.
ConsiderationRÖPLAST SHEETSCorrugated PPCorrugated paperCardboardInjection-mouldedPlastic packaging
Project developmentQuick prototyping with relatively low tooling costs.Quick prototyping with relatively low tooling costs.Dedicated moulds usually require higher initial investment.
Durability & strengthLightweight, with good tear and puncture resistance.Can tear or puncture; strength depends on board construction.Rigid structure; weight and impact resistance depend on resin and design.
CleanlinessNon-fibrous surfaces can be washed and reused.May release paper fibres; limited suitability for wet cleaning.Non-fibrous surfaces can generally be washed and reused.
Cost over repeated useRepeated use can reduce the packaging cost per trip.Often economical for single trips; repeated replacement adds cost.Repeated use can offset higher initial and tooling costs.
Lead timeFast cutting and converting once the sheet specification is agreed.Fast cutting and converting once the board specification is agreed.New products need time for mould design, manufacture and validation.
Waste & recyclingReusable; PP recycling depends on collection and material condition.Recyclable where accepted; frequent replacement creates ongoing waste.Reusable; recycling depends on resin, additives and local collection.
CustomisationReadily cut, folded and printed for application-specific formats.Readily cut, folded and printed for application-specific formats.Changes in shape may require mould modifications or new tooling.
Operational continuityDurable returnable packs can reduce replacement-related interruptions.Damaged or wet packs may need replacement during handling.Durable returnable packs support repeated handling; damage still requires replacement.
Moisture resistanceNon-absorbent PP supports use in wet or humid environments.Uncoated board can lose strength when wet; coatings alter performance.Generally moisture-resistant; performance depends on the selected resin.
Colour optionsA range of sheet colours; custom colours can be specified.Common kraft or white bases, with printed colour options.Colours can be specified; availability depends on resin and production batch.

Indicative comparison for packaging applications. Results vary with material grade, design, quantity and conditions of use.

Applications

SUSTAINABILITY

Circular economy.
Keep materials in use.

Durable polypropylene sheets support repeated use in packaging and industrial applications. Designing for reuse helps make more of the material we use.

01Designed for reuse
02Resource-conscious choices
03Recyclable polypropylene

At the end of their useful life, suitable PP products can be collected, sorted and recycled where appropriate facilities are available.

Polypropylene material cycle: product design, manufacturing, application, use and reuse, collection and sorting, and recycling back into raw material.
