POF shrink film machines
L-sealer and heat tunnel systems commonly used with POF shrink film for clear presentation packaging.
Film choice
Why POF is common for presentation packs
POF shrink film is widely used for retail cartons, books, cosmetics, boxed goods and printed packs because it can provide a clear finish with good presentation. The machine needs to suit the film width, thickness and shrink characteristics.
Machine settings
Seal and tunnel settings affect finish
Film performance depends on seal temperature, seal time, tunnel temperature, airflow and conveyor speed. Small changes in product size or film thickness can require setting adjustments.
Specification
Information needed before choosing equipment
- Film width and thickness, if already selected.
- Product size and desired finished appearance.
- Pack speed and duty cycle.
- Available power and compressed air.

Buyer guide
Check pack dimensions, film type, speed and site utilities before quoting.
Keep the trial tied to a specific POF film
Use the film supplier’s actual product reference in the enquiry. The general description POF does not capture every relevant material property or reel arrangement. Provide the thickness, width, centre-fold or flat format and any supplier processing information already available.
When comparing trial packs, record film changes separately from machine setting changes. If a different grade is introduced to improve appearance, keep both references and the observed result. This avoids approving a machine setup against an unidentified material that may be difficult to reproduce later.
- Reel information
- Confirm core, outside diameter, winding and handling requirements with the proposed equipment. Do not infer reel compatibility from film width alone.
- Material approval
- Identify who approves the final film for the product and any required product-contact or environmental claims. Machine compatibility does not establish those claims.
Will every POF film run with the same settings?
Do not assume equivalent settings. Review the actual film specification and establish the accepted sealing and shrinking conditions for that material and pack.
