Flexible packaging film-reel reports The customer have hot filling process and aggressive recipe of their sauce.

Temperature of the cooking sauce what is filled into sachets is 81-88°C.

Right after, there is also a cooling process in a cooling tunnel which is refrigerating air injection to the tunnel; temperature of the air is 5-10°C.

Cooling time is 15-20 minutes (from 81-88°C to 40°C).

-When inspecting the machine it was noted the sealing temperature of the jaw was shown on the screen was about 260°C.

We informed the customer that was not suitable to work with our film.

Their maintenance team checked the real sealing temperature with the measurement device and what they found out the real temp. was about 160°C.

It was noted the vertical seal 160ºC and horizontal seal 180°C.

-They already put our reels to their two identic machines with the same settings that the competitor’s film run.

We started to produce sachets without product inside.

The machine cuts and seals the film the number of 4 lanes and they fall down an assembly line.

We observed the running of the film about 10 min. and we did not see any problem during that time.

We started to produce sachets filled with the product 120gr inside.

We observed the running of the film about 2 hours and we did not see any problem during that time.

They confirmed that the seal quality was good.

We took empty and filled samples from the trials.

We also took competitor samples in order to compare with our film regarding to physical properties.

-The customer makes quality test on the sachets by using Mecmesin ILC-S 5000N force and torque measurement systems and they want us to pass their quality standard.

They try to find a proper test conditions because of the test machine newly- bought but generally they are using following conditions for competitors ‘’100Kg pressure and 10 seconds wait between two columns.

They put 1 sachet in test area each time and they checked whether there is a leakage on the sealed area of the sachets or not.

For 50 Kg and 10 Seconds our film passed the test, for 100Kg and 10 Seconds our film did not passed the test every time.

Their quality team told us that the sachets was too hot(40°C) to make a proper test.

They were going to do a test in a room temp. after 3-4 hours.

They will inform us about test results.

We discussed one more topics during our visit, the customer told us that there were fluctuations on the reels and some winding problems as well.

This caused the incorrect cutting of the film after sealing.

They would not like to use the reels for next trials or orders like below pictures.

According to our test results, there was not big difference between our and competitor film as shown below table.

The running performance of trial was good; Mr. Franz was satisfied about film performance.

The customer took 2 pallets samples from the trial to make shelf life tests in their curing room(in 40°C).

Shelf Life Test takes from 12 to 24 weeks.

Depending on their test results, we will produce an industrial order.

Additionally, they will make four more trials for the different aggressive recipe of their sauce.
