The heat shrink chamber creates a highly secure and tamper proof shrink wrapped product or package.
Using a simple operation the shrink wrapping machine is designed to speed up your production lines. Whether you are shrink wrapping a large number of bulk products for despatch or shrink wrapping for a retail display, this machine will provide a reliable and consistent performance.
Since the shrink wrapping machine is mobile, this allows it to be maneuvered easily throughout your workshop or factory.
BASIC SET UP
The shrink wrapping machine is practically ready to use out of the crate…
Carrier set up:
All that is needed is to slide the roller carrier into the guides which then clip to lock it in place.
Installing the film in the carrier:
The shrink wrapping film roll support axle and mandrels are put into the core of the film.
The axle is laid onto the carrier bearing with the film unreeling in a clockwise direction with the
film open side to the front.
Threading the film:
The shrink wrapping film is drawn from the carrier
It is then run through the perforator roller and then opened to run one side under and the other side over the separator plate.
Adjusting for the depth (front to back length) of the product:
The separator plate, the carrier and the perforator can all be adjusted on their guides to allow for larger or smaller product sizes.
The closed side of the film should be about 4 cm from the products rear side.
The open side will overhang the front of the machine.
Making the weld:
For the first cycle a dry run is done to get a seal line on the film which will be pulled to the left side of the product.
Do not weld for more than 1,5 sec or the film will burn and smoke and you may damage the heaters.
Correct film overhang:
The shrink wrapping film is drawn to the left so that the welded side of the film is about 4 cm from the product and the right side and front sides of the product is about 4 cm from the edge of the basket.
This will mean that the welded film will be a fairly close fit around the product and will require minimal time to shrink to size.
Use of the perforator:
The perforator makes small holes in the film to allow the excess air to escape when the film is shrinking, if there are no holes the film will just make a “pillow”
It is set so that the perf line is located mid way across the product.
Timer and temperature adjustments:
Temp adjustment is carried out using the digital display to about 240°C
Weld time is adjusted by the timer and is set between 1.5 seconds or the film will burn and smoke. (test runs are recommended)
Shrink time is set to about 7 sec initially when chamber temp is at 240°C and then as the work progresses can be brought to about 5 sec.
Note: The product should be at room temperature or the shrinking process will be greatly slowed down…
a lower temp will not shrink the bopp film.
