Shrink Tunnel Machine Pallet Collars

Product Description
Features:
1.This machine is used in the shrink- wrap packaging materials outside. After heating, the shrink film contracts and get close to the surface of the packaging which fully demonstrates the appearance to increase the aesthetic value and sense. Meanwhile packaged goods can reach the purpose of sealed, moisture proof, pollution prevention, anti-breakage and theft;
2.It is also used for a variety of combinations and pallet packaging;
3. It is widely adopted in large-scale product pallet. The entire package can match with anti-radiation PE shrink film, which can protect the gloss and water & dust-proof but also photochemical oxidation;
4. The pallet shrink wrapping machine is main to instead of stretch wrapper with the advantages--more aesthetics, integrity and easy transportation;
5.This machine can be used independently with the function of wrapping goods transportation, heating, fitted, and cooling completed in one time. It adopts automatic temperature control, hot air circulation, energy-saving and efficient. The speed is adjustable and stability equipped with a powerful cooling system;
6.The machine has advanced design, reliable performance, good contraction effect, beautiful & new structure;
7. Operation and maintenance are convenient, suitable for a variety of continuous shrink film packaging.

FAQ
Shrink Film Flatulence： Hot Air Is Retained In The Shrinkable Film
Solutions:
1. to increase ventilation hole number, to accelerate the air leak from the shrink film
2. Conveyor speed --to slow down the packaging machine, so that the hot air has a longer time from shrink leaking
3. adjustable high machine temperatures to help the air leak from the film.
Atomization: Shrink film surface becomes blurred, like a mist
Solutions:
1.Reduce the shrink tunnel temperature, the temperature is too high so cause shrinkage film atomization;
2. Increase Conveyor speed of shrink tunnel, reduce the time of contact heating;



Weak sealing line: Sealing line is easy to damage or the emergence of small holes.

Solutions:

Turn down the temperature of sealing blade;
The sealing line height is wrong. The line should be posited in the middle of the height;
The pressure of the sealing blade frame is not even, should adjust the horizontal position of the frame;
The heating blade and the sealing base may dirty, should clear the two parts.

Fisheye problem: Shrink film surface appears fisheye like wrinkles.
Solutions:
The temperature of the shrink tunnel is too low, turn up the temperature;
The speed of the conveyor is too fast, turn down the speed;
The circulation wind volume of the shrink tunnel is too low, turn up the circulation wind.

Fine wrinkles: Corner and edge series of wrinkles in the contraction film.
Solutions:
There are too many holes on the film. The air on the film goes too fast, so the film can’t shrink enough, reduce the holes;
The speed of the conveyor is fast, so reduce the speed;
The temperature of the shrink tunnel is too low, turn up the temperature;
The circulating wind of shrink packaging machine is too low, can make the circulating wind up.

Dog ear：Shrink film in packaging angle triangle protrusion.
Solutions:
The plastic bag is big and made it smaller;
The speed of the conveyor is too fast, turn down the speed;
The circulation wind volume is too big, reduce the wind volume;
The temperature of the shrink tunnel is too slow; you can turn up the temperature.

The sealing position error: The position of the sealing line is halfway to the packing height.
Solutions:
The height of the sealing conveyor is wrong; adjust the height to suitable position;
The height of the sealing frame is wrong. Adjust the height to suitable position;
The circulation wind direction is wrong, adjust the wind direction;
The sizes of the bag is too big, make the bag smaller.
