Pre-Stretch Rollers for Stretch Wrappers

Optimize your pallet wrapping line

The pre-stretch roller is a critical component in any industrial packaging process. At Soremag, we design and build custom rollers that combine durability, performance and precision: calibrated surface, adjusted durometer and durable compounds to get the most out of your wrapping machines.

The result: reduced film consumption, improved load security and longer service life for your equipment. We build new rollers, we replace OEM parts and we refurbish your existing rollers.

What is a pre-stretch roller?

A key component of pallet wrapping machines: it stretches the plastic film before it is applied to the load, so that each layer clings properly to the pallet and to the products.

Réduction des coûts : en pré-étirant le film, jusqu'à 50 % moins de matière peut être nécessaire pour sécuriser chaque palette.
Stabilité renforcée : le film étiré possède une « mémoire élastique » qui le resserre continuellement, pour une tenue des charges pendant le transport.
Efficacité opérationnelle : un étirement contrôlé réduit les ruptures de film et les arrêts machine.
Protection optimale : l'application uniforme et tendue protège la charge contre la poussière, l'humidité et les égratignures.

The pre-stretch process

Pre-stretching is a precise mechanical operation that takes place in the film carriage, using a two-roller system: the

primary (feed) roller

, which pulls the unstretched film off the film roll, and the

secondary (pre-stretch) roller

, which turns at a higher surface speed.

This speed difference stretches the film in a controlled way before it wraps the load. It activates the film's “elastic memory,” improves its strength and reduces material consumption. The level is

commonly 150% to 300%

(some films and carriages reach

up to 400%

), most often set between 200% and 250% depending on the carriage and the film.

Bon à savoir — l'équilibre des deux rouleaux

Performance depends on the

balance between the primary roller and the secondary roller

: speed ratio (gear ratio / diameter), relative grip and surface condition. If you replace only one of the two, you have to respect that ratio and that grip to keep the pre-stretch level and

avoid slipping

Our custom fabrication expertise

We go beyond standard supply: complete fabrication, customization and adaptation to your equipment.

Complete pre-stretch system

We build both components: the primary (feed) roller and secondary (pre-stretch) roller. The balance between the two is critical to optimal performance.

Adjusted durometer (Shore A)

We adjust the durometer to optimize grip while minimizing wear and film marking.

Surface texture

Smooth, knurled or fluted (grooved), depending on your film type and the level of grip you need.

Custom dimensions

Any length and diameter, for standard and special equipment — from a sample or from drawings.

Special compounds

Oil resistant formulations and formulations for high performance applications, based on your plant conditions.

Specialized adaptation

We also modify rollers for specific equipment such as stretch netting.

Which cover for your film?

We select the material, the durometer and the texture based on your film and your machine — no guesswork.

Choix	Ce qu'on ajuste	Pourquoi
Polyuréthane	Revêtement anti-abrasion / anti-coupure, adhérence contrôlée	Référence pour les systèmes motorisés de pré-étirage : longévité et grip constant.
Caoutchouc	Formulation et dureté selon le film	Option selon l'adhérence recherchée et le budget; possible selon l'application.
Dureté (Shore A)	Ajustée à la hausse ou à la baisse	Assez d'adhérence pour entraîner le film, sans le marquer.
Texture / rainurage	Lisse, grainée ou cannelée	Adaptée au type de film pour un grip suffisant sans patinage.

Frequently asked questions — pre-stretch rollers

What is a pre-stretch roller? +

A roller — or a primary/secondary roller pair — that mechanically pre-stretches the film between two rollers turning at different speeds, before it is applied to the load. The result: less film used and a more stable load.

How does pre-stretching work on the machine? +

The secondary roller turns faster than the primary; the film is pulled between the two and elongates according to the speed ratio (commonly 150% to 300%, up to 400% depending on the film and the carriage, most often between 200% and 250%).

What materials do you use? +

Mostly

polyurethane

(abrasion and cut resistant, controlled grip) on a steel or aluminum core — the reference for powered systems. Rubber is also possible depending on the film and the application.

Do you offer standard sizes and custom work? +

Yes: the common standard sizes, and fabrication to specification (diameter, length, bore, grooving, texture, cover durometer and target ratio).

What are the concrete benefits for the user? +

Less film used, fewer breaks, better tension control and more stable loads — that is the whole point of pre-stretching before application.

How do you choose the right cover? +

We adjust the cover durometer, the surface roughness and the compound to the film and the use: enough grip to drive the film without marking it, and good wear resistance.

Can I replace only one of the two rollers? +

You can, but you have to respect the drive ratio and the relative grip between the two rollers to keep the pre-stretch level and avoid slipping.

Do your parts replace the OEM part identically? +

We aim for functional equivalence (or better): same dimensions and same performance from the pre-stretch system. We can also refurbish your existing roller.

Maintenance and service life? +

Check alignment, surface cleanliness, tension and bearing condition; replace worn covers to maintain stretch quality. We can advise you on this.

Lead times and refurbishment? +

We build and we refurbish to minimize line downtime, with faster options depending on shop load. See emergency & logistics.
