Cast Stretch Films
We produce stretch wrap films in our modern production facilities. This assures that we will have the right type of product to offer our customers regardless of the application. Our stretch wrap film manufacturing facilities are ISO certified to ensure we produce the highest quality products consistently and cost-effectively.
Specifications
This Technical Specification concerns the Polyethylene, 3-layer, LLDPE & mLLDPE stretch film manufactured with the use of the CAST film extrusion technology.
| Thickness (μm) | 19 | 23 | 25 |
|---|---|---|---|
| Width (mm) | 500 | 500 | 500 |
| Roll Length (m) Machine Roll | 1000 / 1500 / 1800 / 2900 | 1000 / 1500 / 1800 / 2900 | 1000 / 1500 / 1800 / 2900 |
| Roll Length (m) Hand Roll | 100 / 300 / 500 | 100 / 300 / 500 | 100 / 300 / 500 |
It is possible to manufacture the film of custom thickness or length after having consulted and confirmed with our customer.
Characteristics
Our Cast stretch film is manufactured using the cast extrusion process. Typical characteristics of cast stretch films are: excellent optics, clear, glossy, superior tear resistance, quiet unwind, consistent cling and consistent film thickness.
- improved stability of products or packages, forming a unit load
- more efficient handling and storage of unit loads
- some degree of dust and moisture protection
- some degree of tamper resistance and resistance to package pilferage
- some degree of sun protection (UV stretch wraps)
Mechanical Properties
Mechanical properties of stretch film are determined based on tests performed with the use of a device simulating the operation of a wrapping machine in laboratory conditions.
- During the Quality test, the strength and quality of the film are checked on a guaranteed stretch
- The Ultimate test determines the maximum stretch [%] when the film starts to rupture
- The Puncture test determines the force [kg] needed for puncturing the film
- The Retention test determines the maximum force [kg] exerted by the film in reaction to a point pressure
| Thickness (μm) | 19 | 23 | 25 |
|---|---|---|---|
| Stretch (%) | 300 | 320 | 370 |
| Stretch before rupture (%) | 380 | 395 | 430 |
| Puncture force value (kg) | 1.99 | 2.18 | 2.55 |
| Load retaining force value after 60 s (kg) | 1.26 | 1.42 | 1.78 |
*Guaranteed stretch of the film is determined in laboratory conditions. The way the film behaves on a wrapping machine depends on individual wrapping machine settings and the type of load being wrapped.
The film maintains its physicochemical properties for up to 12 months when storing the product in the conditions of average yearly insolation of 100 kLy.
