What Is Tuffilm?
Tuffilm is a dart impact strength additive formulated specifically for reprocessed polyolefin films and liners. Added at a low dosage of 1% to 3% of batch size, it helps restore and improve the impact resistance lost during reprocessing, allowing manufacturers to use recycled and reprocessed material with confidence while maintaining film integrity.
It is compatible with existing film processing lines — no equipment change required.
Why Reprocessed Polyolefin Film Loses Dart Impact Strength
Every time material goes back through heat and shear — extrusion, grinding, re-extrusion — polymer chains break. This is called chain scission, and it thins out the entanglement network that gives film its toughness.
Tensile strength usually survives this. Dart impact doesn’t. It’s the property most sensitive to reprocessing damage — which is why a reprocessed film can test fine on paper and still tear in a customer’s hands.
The result on the shop floor
A hard ceiling on how much recycled content you can safely use.
That last point is the real cost. If dart impact caps you at 20% recycled content when your economics say 40%, that gap is money left on the table every day.
Key Benefits of Tuffilm
Improves dart impact strength in reprocessed films
Carry bags and garbage bags that split under load
Enables higher recycled material use without sacrificing performance
raise your recycled fraction and keep the quality.
Reduces rejection and wastage from tearing and puncture failure
less material scrapped, fewer consignments returned.
Low dosage of 1–3% for cost-effective formulation
a small addition against a meaningful material-cost saving.
Compatible with existing film processing lines
no new equipment, no process redesign.

Applications
Where Tuffilm Fits
Carry Bags
Thin-gauge film carrying concentrated point loads. Handle tears and base splits are almost always dart impact failures, not tensile ones — which is why they show up so quickly once recycled content goes up.
Garbage Bags
The most punishing use case in the category: irregular loads, sharp contents, sudden drops. Puncture and tear resistance is the entire product promise.
Tarpaulin
Outdoor service under wind, load and eyelet stress. A tirpal made from reprocessed material needs its impact strength back before it can be trusted through a season.
Nursery Sheets
Long service life in sun and handling. Failure mid-cycle means losing the crop the sheet was protecting, so buyers judge harshly on durability.
Mulch Film
Laid mechanically across rough ground, then left exposed for months. Tear propagation during laying is a common and expensive rejection point.
Recommended Dosage
Use 1% to 3% of batch size, depending on the quality of your raw material
FAQs
Tuffilm is a dart impact strength additive for reprocessed polyolefin films and liners, including carry bags, garbage bags, tarpaulin, nursery sheets and mulch film. It restores impact resistance lost during reprocessing.
The recommended dosage is 1% to 3% of batch size. The right figure depends on the quality of your raw material — more heavily reprocessed material generally needs the higher end of the range.
Repeated thermal and mechanical processing breaks polymer chains, which thins the entanglement network that gives film its toughness. Dart impact is the property most sensitive to this damage, which is why reprocessed film tears and punctures more easily.
That is its main purpose. By improving dart impact strength in reprocessed systems, Tuffilm lets manufacturers use a higher proportion of recycled or reprocessed material without sacrificing film performance.
No. Tuffilm is compatible with existing film processing lines.
It is formulated to reduce rejection and wastage caused by film tearing and puncture failure. The actual reduction depends on your current rejection cause and blend, which is why we recommend a trial on your own line.

Potential applications include rigid PVC and UPVC pipes, conduit pipes, PVC edge bands, PVC windows and doors, PVC profiles, casing and capping, PVC flooring, and PVC cable compounds.
