JEM STRAPPING SYSTEMS

Blown Stretch Film uses a melted plastic resin extracted into a closed circular bubble with air blown throgh to cool the resin. The inflated bubble is pulled upward by air and continuously adding more resin. Airflow is also used on the outside of the bubble to cool the film as it is being pulled upward. A continuous seamless tube of thin film is created. After the film has cooled it is slit, flattened, and wound into rolls.

Because blown stretch film uses a slower air cooled method, the film can crystallize and have a slight haze. Blown Stretch Film is often stronger than cast and can offer the ability to use a lower gauge compared to cast. We recommend blown film for companies wrapping very heavy pallet loads with sharp edges and corners.

Initial machinery start-up costs are often more for Cast Stretch fILM in comparison to Blown; however, production is much cheaper than Blown Stretch Film. Cast Stretch Film offers the ability to make very thin uniform film. Hybrid stretch films and equivalent stretch films are made with the cast stretch film process.

Cast Stretch Film uses rollers to cool plastic resin. Once the resin is extracted from the extruder, it is immediately cooled and solidified on cooling rolls. When the film reaches the end of the cooling rolls it is trimmed and can be rolled directly onto a material roll for resale.
