Stretch film choice can make the difference between a stable shipment and a pallet that shifts halfway to its destination.
Every load is different, and so is every film. Finding the right balance of strength, flexibility, and tension control is key to consistent performance.
Nitech IPM helps customers match their film, machine, and load type to get reliable wraps without wasted material.
1. What Defines Film Performance
- Tensile Strength: resistance to breakage under load.
- Cling: how firmly layers bond to one another.
- Puncture Resistance: ability to stretch over corners without tearing.
- Elastic Memory: film’s natural pullback that keeps loads tight in transit.
- Clarity: visibility for scanning and product ID.
Balanced correctly, these properties deliver secure loads with minimal film usage.
2. Pre-Stretch and Film Force
Pre-stretch increases film yield and strength before it reaches the pallet.
Film force is the tension as the film tries to recover its shape after being stretched.
Too much force can crush packaging; too little lets loads move.
Nitech IPM wrappers let operators program both variables for each product, ensuring consistent hold and repeatable results.
3. Matching Film to Load Type
- Uniform loads pair well with cast film for smooth, quiet wrapping and high clarity.
- Mixed or uneven loads often need hybrid or blown film for added tear resistance.
- Heavy or irregular loads perform best with blown film, which resists puncture and keeps force consistent.
Multiple wrap profiles can be saved on Nitech IPM machines for quick switching between load types.
4. Environmental and Equipment Factors
Temperature, humidity, and speed all affect film performance.
Cold rooms stiffen film; high speeds generate heat and static.
To stay consistent: store film at stable temperatures, maintain pre-stretch rollers, and match film quality to machine capability.
5. The Payoff: Consistency and Savings
Dialing in the right combination of film and wrapper pays off quickly, stronger wraps, reduced damage, and lower material use.
Even small improvements in stretch control can cut film costs while improving safety and load appearance.
Choosing stretch film is about balance, not brand.
When your film, machine, and load type work together, every pallet leaves the dock secure and consistent.
That’s the standard Nitech IPM helps customers achieve every day.
