Machine-Grade UVI Stretch Film
Our machine-grade UVI (Ultraviolet Inhibitor) stretch film is engineered with advanced chemical additives that prevent sunlight from degrading the film’s molecular structure. It is the gold standard for maintaining load integrity in outdoor storage yards and flatbed transit. Designed for automated orbital stretch wrapping machines, our UVI films offer high elasticity and strong cling to prevent pallet shifting on moderate to heavy loads.
- Prevents "Chalking" & Brittleness
- Cast & Blown Options (Quiet release or high puncture)
- Maintains Memory in 100°F+ Heat
- 6 to 12-Month Outdoor UV Resistance
Machine Compatibility & Regional Specs
Outdoor Storage
Ideal for landscaping (mulch/sod), building materials (bricks), and agricultural equipment stored in open yards.
ASTM G155 Certified
Passes rigorous Xenon Weatherometer lab testing to guarantee LLDPE surface integrity for 6 to 12 months of outdoor exposure.
Skylight Protection
Essential for pallets stored near warehouse windows or skylights where indirect UV still causes material fatigue.

The Application: Architectural EPS foam insulation must be stored on open-air job sites for months. Standard stretch film quickly degrades in the sun, leading to crushed corners and scattered pallets. Watch our 90-Gauge UVI Clear Film applied by a Pro 1100 Wrapping Cell to secure these highly fragile structural forms.

Engineering FAQ: UVI Film Specifications
How does the UVI additive prevent LLDPE polymer degradation during prolonged UV exposure?
The Ultraviolet Inhibitor (UVI) additive acts as a chemical sacrificial layer. It absorbs and dissipates both UVA and UVB photon energy before it can break the carbon-carbon bonds within the LLDPE polymer chains. This stabilization prevents the photo-oxidative degradation process - commonly observed as "chalking," severe brittleness, and loss of elongation - maintaining structural integrity for 6 to 12 months in outdoor environments.
Does the inclusion of UV inhibitors affect the power pre-stretch yield of the machine film?
When properly extruded at heavier gauges (80 to 100 micron / 20.3 to 25.4 µm), the addition of UVI masterbatches has a negligible impact on the film's elastomeric properties. Our UVI machine films can still reliably achieve a 200% to 250% power pre-stretch yield on automated carriages without inducing premature web snaps or compromising the chemical cling force.
How does UVI stretch film mitigate thermal "snap-back" loss on dark, heat-absorbing loads like asphalt shingles or black plastics?
Dark-colored outdoor loads can reach surface temperatures exceeding 140°F (60°C), pushing standard films past their glass transition phase and causing permanent elastic deformation (loss of load containment). Our UVI films are co-extruded with heat-stabilizing resins that resist thermal expansion, ensuring the film retains its "snap-back" memory and continues to apply constant containment force despite extreme diurnal temperature swings.
Is clear UVI film sufficient for protecting light-sensitive products, or is opaque UVI required?
Clear UVI film prevents the plastic wrap itself from degrading, but it still transmits up to 90% of visible light and a portion of UV radiation to the product beneath. For photosensitive goods (e.g., dyed textiles, certain chemicals, or unprotected plastics), packaging engineers must specify an Opaque Black or Opaque Blue UVI film (e.g., SKU: VMUVI20580B) to provide a total photolytic barrier.
