Blown Machine-Grade Stretch Film
Manufactured via a specialized blown extrusion process, our heavy-duty machine-grade blown stretch film is engineered for maximum puncture resistance, rupture prevention, and superior load-holding force. It is the industry standard for securing heavy industrial loads, C-type pallets, and abrasive surfaces on both semi-automatic and fully automatic orbital stretch wrapping machines. High film memory "snaps back" to tightly lock in long, irregular, or sharp-edged profiles.
- High-Tack Aggressive Cling (Layers adhere without slipping)
- Pre-Stretch Compatibility (Controlled film delivery)
- Resists Tearing on Jagged Corners & Abrasive Loads
- High Memory (Snaps back for load stability)
Machine Compatibility & Regional Specs
High-Memory Cling
Superior "snap-back" memory ensures loads stay tight during long-haul transit vibrations.
Excellent Cling
Aggressive tack ensures the film bites into itself instantly, locking heavy, irregular loads in place.
Extreme Puncture
Toughened resin formulated to resist tearing from sharp lumber, metal, or jagged crates.

Engineering FAQ: Blown Machine Film Specifications
How does blown machine film mitigate tear propagation on Type C loads with sharp metal or masonry extrusions?
The blown extrusion process forces bidirectional molecular orientation during the bubble-cooling phase, which significantly increases dart drop impact strength compared to cast alternatives. This cross-linked polymer memory actively halts zip-tear propagation upon puncture, making heavy gauges (90 to 120 micron / 22.9 to 30.5 µm) structurally critical for Type C loads like steel rebar, jagged brickwork, and exposed lumber.
What are the cling mechanics of blown stretch film in high-particulate or dusty manufacturing environments?
Unlike cast films, blown stretch films utilize a highly aggressive, tackified Polyisobutylene (PIB) additive that migrates from the resin core to the film surface. This chemical cling generates high-shear layer-to-layer adhesion (frequently >200 g/in peel cling) that easily penetrates dust and particulate interference, preventing web delamination and load shifting in masonry or construction material facilities.
Does blown stretch film maintain its elongation at break and containment force in sub-zero cold chain logistics?
Yes. Blown LLDPE resins possess exceptional low-temperature flexural strength, allowing the film to maintain its elastic memory and resist brittle fracture down to -20°F (-28°C). The crystalline polymer structure developed during the ambient air-cooling extrusion process prevents the film from reaching its glass transition phase prematurely, ensuring consistent load containment force inside commercial blast freezers.
What are the power pre-stretch carriage limitations for blown film regarding neck-down and web width retention?
Blown machine films typically support power pre-stretch settings between 150% and 250% before yield failure. Because of its inherent multidirectional elasticity, blown film exhibits excellent width retention, avoiding severe "neck-down" (width narrowing) during high-velocity carriage acceleration. This ensures maximum surface area coverage per rotation, even under extreme containment tension.
