In brief
Width and micron do not make two hand films equivalent. Net film weight, length, core, formulation, unwind and behaviour in use all affect the comparison.
Create a common data sheet, verify exact product references and then test on the same load families.
Identify the complete roll
Record product reference, width, stated thickness, usable length, gross and net film weight, core dimensions, rolls per case and cases per pallet. Note declared tolerances and data source.
Separate dimensions from performance
Micron is thickness, not a guarantee of puncture resistance, holding force or applied stretch. Treat quoted performance values as product-specific only when the test method and exact film are identified.
Match the film to manual application
Compare unwind, cling orientation, neck-down, roll weight and dispenser compatibility. Observe different trained operators because manual tension and overlap can vary.
Run a controlled load trial
Use normal and difficult pallets. Record applied mass, break rate, rewraps, wrapping time, roll changes and condition after representative handling. Do not change film and technique simultaneously without documenting both.
Approve a product and process together
The final standard should identify the film, load family and approved application. Add change control so a nominally similar replacement is not introduced without review.
| Category | Compare | Why |
|---|---|---|
| Roll content | Net weight and usable length | Normalises purchase units |
| Physical | Width, micron, core and tolerance | Confirms format |
| Application | Unwind, cling and dispenser fit | Tests operator usability |
| Outcome | Applied mass, breaks and load condition | Tests operational value |
Practical checklist
- Use exact product references
- Compare net film rather than gross roll weight
- Request methods behind technical values
- Include multiple load families and operators
- Document approved film and application
