Recent research by PCI indicates that the Indian flexible packaging market is set to growby over 17% per annum over the next few years compared with around 10% per annum for China.

The last year have showen a rising demand for hygiene products and especially for those withbreathable film.This materials,formerly mainly produced on cast film lines is now shifting towards blown filmfeaturing enhaced properties,less thickness and therefore also big potential for materials and cost savings.

Against a backdrop of uncertain global growth the IMF is forecasting thatIndia's GDP growth will outpace that of a showing Chinese economy next year.What does this mean for the relative propects for flexible packaging in the two countries?

Compounding was done with a twin-screw extruder at 220Deg C,300rpmand nitrogen(1,5 bars) was used to make the compounding stepas inert as possible.HDPE powder and additives were mixed mechanically before compounding.Multiple extrusions were done with a single screw extruder under air atmosphere.

To transition from LLDPE to a material with similar os lower MI PEs(ie.,higher viscosity PEs),the expected purge time should be 10-20minutes or less.Once the product run is over,remove the LLDPE blend from the chute of the extruder's hopper,andthoroughly clean the hopper to ensure that all the material is gone.If the new PE material has much less viscosity(much higher MI) than the exsiting LLDPE,then a LDPE with an intermediate MI is recommended as an additional step.

When purging acidic materials such as EVA,lonomer os EAAs out of the system,It is important that the temperatures be kept at their respective processing temperature first.

To purge LLDPE with pigment MB out of the system,it is expected thatthe process will take about 15-45minutes,sometimes longer,depending on the pigment and the die characteristics.Once the product run is over,the operator needs to remove the LLDPE +pigment MB from theChute of the extruder's hopper,and thoroughly clean the hopper to ensure thatall the materials is clean.Purge using the "Alt-Disco"purge technique with a 1MI LLDPE or a 0.8-1 MI LDPE(depending on the next Materials) while maintaining the bubble and making sure that the temperatureprofile is maintained(sometimes lowering the temperature profile by 10-15Deg C can shorten changeover time).

To transition out of PA or EVOH,the average transition time should be about15-45minutes depending on the size and design of the die.Once the product yun is over,the operator needs to remove the PA or EVOH from the chute of theextruder's hopper and tgoroughly clean the hopper by using a vacuum to ensure that all the materials is clean.It is also an ideal time to clean the hopper's magnet by vacuum and to make sure that there are no pellets left hanging in the gravimetric system/blenders.

Even though all these polyethylenes are around 1 MI,it can be seenthat at both temperatures,the LDPE has much lower viscositiesthan those of LLDPE and mLLDPE.
