Understanding heat shrink technology in packaging
Heat shrink technology in packaging is done by applying heat to a shrink film material in a controlled manner, thus making the film to contract and tightly conform to the product’s shape. The effectiveness of this process depends on several critical technical parameters:
- Temperature Range: Based on the type of shrink film a controlled temperature range of 100°C~200°C provides the optimal shrink reaction to PVC and Polyolefin films.
- Film Type: A common variety of the shrink films is PVC, polyolefin, and polyethylene which are chosen for durability, transparency, and puncture resistance among other application needs. Polyolefin, for example, is very common because of its wide application range and FDA approval for food packaging. Polyolefin is also commonly used because it has a shrink ratio between 40 and 60 percent.
- Conveyor Speed: Allowable adjustable conveyor speeds ranging between 10 and 120 feet per minute help manage different product sizes and production loads without affecting shrinkage quality.
- Sealing Method Automated systems seal L-sealers or side sealers, and some use continuous motion technology based on the output requirements of the production line. These methods are essential for achieving a seal that improves the product’s protection and visual appeal.
- Heat Tunnel Uniformity: The shrink tunnel must have even heat distribution to prevent inconsistencies such as uneven shrinkage or film wrinkling. Precise airflow systems provide this.
The precision of these technical parameters in shrink packaging technology combine an aesthetic design with high levels of protective qualities while minimizing unused film and maximizing throughput efficiency. These factors are relevant for packaging workflows in every industry.
Differences between Automatic and Manual Shrink Wrap Machines
