Pillowpack.

The soap tablets packed with a film like " a pillow ". Today, Pillow pack model is the best model of soap packaging to give a protection from any other contaminant because the product packed closely inside the pillow film. But the critical point must be aware is the " T " mark, must be free from leakage. This leakage frequently happen from the sealing temperature of machine not enough to melt the sealable layer packaging material or the jaw seal of machine damage in giving a good sealing pattern performance.

Specification of packaging material commonly used is :

1. 
   
   PET12/ink/PP30 ( extrusion process )


2. 
   
   PET12/ink/LLDPE30 ( extrusion process )


3. 
   
   PET12/ink/adh/LLDPE30 ( dry lamination process )


4. 
   
   BOPP20/ink/PP20 ( extrusion process )


5. 
   
   BOPP20/ink/adh/BOPP20 ( dry lamination process )


6. 
   
   BOPP20/ink/adh/CPP20 ( dry lamination process )

Specially for type 1 - 3, The temperature of machine operation can be operated in this range : 140 - 185 oC. This type of material packaging is good in Heat Resistance but not recommended to operate the temperature sealing of machine more than 190oC.

For type 4-6, The temperature of machine operation can be operated in this range : 140 - 160oC. This type of material packaging is good in moisture resistance but not good in Heat Resistance, so not recommended to operate the temperature of sealing machine more than 165oC.

The type of machine commonly used is HFFS machine likes PFM lines that can be operated till 250 packs/min.
