What Are Narrow Polythene Films?
Narrow polythene films are thin strips of polyethylene (PE) material, typically ranging in width from 20mm to 500mm. They are used extensively in stretch banding, bundling, wrapping, and sealing applications. The narrow width allows for precision application while reducing waste and material costs.
These films are ideal for use in:
Automatic wrapping machinery
Logistics and pallet securing
Product bundling
Agricultural packaging
Construction and industrial protection
The Importance of Quality in Film Production
Quality is paramount in the production of narrow polythene films. Each step in the manufacturing process is designed to ensure that the final product meets the highest standards. This dedication to quality is what sets us apart in the industry.
Step 1: Sourcing High-Quality Polythene Resin
Every roll of narrow polythene film we produce starts with the highest-grade polyethylene resin. We work with trusted UK suppliers to ensure consistency in the raw material’s quality and performance. Depending on the application, we may use:
Low-density polyethylene (LDPE) for flexibility and clarity
High-density polyethylene (HDPE) for strength and stiffness
Linear low-density polyethylene (LLDPE) for enhanced stretchability.
By choosing the right resin blend, we tailor the film’s properties to suit specific industrial needs.
Step 2: Film Extrusion
Next, the resin is fed into our extrusion lines, where it is melted and formed into a thin, continuous sheet of film. This is achieved through a blown film extrusion process, which allows us to control:
Thickness (micron level)
Clarity and gloss
Tear resistance
Stretch performance
We closely monitor temperature, pressure, and extrusion speed to maintain precise control over the film’s characteristics.
Step 3: Slitting to Narrow Widths
This is where our expertise in narrow polythene films truly shines.
Once the film is cooled and flattened, it moves to the slitting stage. Here, razor-sharp blades are set to the desired width to convert the large master roll into multiple narrower rolls. Our slitting machines are capable of producing films as narrow as 20mm, with millimetre precision.
Key advantages of our slitting process include:
Custom widths for unique machinery requirements
Minimal edge waste
High-speed, high-volume output
Consistent roll tension for easy machine feed
Step 4: Winding and Packaging
After slitting, the narrow films are carefully wound onto cardboard or plastic cores, depending on the client’s needs. We offer various core sizes and roll lengths to accommodate automatic systems or manual use.
Each roll is:
Individually quality-checked
Labelled with full traceability data
Securely packed for transit
Our packaging ensures that your narrow polythene films arrive in perfect condition, ready for immediate use.
Step 5: Customisation and Quality Control
At Stretch Band Packaging, quality is non-negotiable. Every batch of film undergoes rigorous testing for:
Thickness and gauge consistency
Stretch and tensile strength
Puncture resistance
Load containment performance
We also offer bespoke options, including:
Coloured or printed narrow polythene films
Perforated or pre-slit rolls
UV-stabilised or anti-static formulations
If you have a specific need, we can manufacture to match your exact technical and performance specifications.
