PE shrink film in sleeve sealing
PE shrink film is commonly considered for multipacks and transit packs because it can provide durable containment for grouped products. The film specification must be matched to pack weight, machine route and shrink tunnel settings.
Film width, thickness, roll handling and shrink characteristics all affect the result. A pack that is too heavy for the film, or a tunnel that is not suited to the film, can create poor shrink quality or unreliable handling.
Film details to confirm
- Film material, thickness and roll width.
- Pack weight and handling requirement.
- Required film overlap and seal position.
- Shrink tunnel temperature and belt speed.
- Finished pack appearance and transit strength.
| Film width | Must suit the pack width, height and required overlap. |
|---|---|
| Film thickness | Should match pack weight, handling and finish requirements. |
| Tunnel settings | Temperature, airflow and dwell time affect shrink quality. |
