Performance of SB – PET Containers over BG – PET Containers & HDPE Containers.
Si.No | Are of Comparision | HDPE | Bottle Grade PET | Silver-Barrier PET | Advantages of Silver-Barrier |
---|---|---|---|---|---|
1 | Strength of Container | good | Better | best | More sturdy packaging solution , more scope of light Weighting |
2 | Oxygen Barrier | good | Better | best | Helps to improve shelf life |
3 | Moisture Barrier | Better | good | best | Helps to improve shelf life as have moisture barrier even better that HDPE |
4 | Container weight for same volume of bottle |
Higher | Lower | Lowest | Less raw material cost |
5 | Master batch requirement | Yes | Yes | No | Saving on master batch cost |
6 | Polymer Price | Higher | Lower | Lowest | Saving on product cost |
7 | Overall Cost of Container | Higher | Lower | Lowest | Because of saving on material cost + master batch cost + scope of light weighting |
SB – PET Containers are Cost Effective than BG – PET Containers & HDPE Containers.
Si.No | Are of Comparision | Bottle Grade PET | Silver-Barrier PET | Advantages of Silver-Barrier PET |
---|---|---|---|---|
1 | Compression Strength | Lower | Higher | More sturdy packaging solution & scope of light Weighting |
2 | Opacity | No | Highly Opaque | Better UV Resistance and improved Appearance of Containers |
3 | Masterbatch Requirement | Yes | No | Savingon Masterbatch Cost |
4 | Moisture & Oxygen Barrier | Good | Better | Helps to improve Shelf Life |
5 | Cost of Container | Higher | Lower | Due to Saving on Material cost + Masterbatch Cost + Scope of Light Weighting |
SB – PET Containers are Superior than Bottle Grade – PET Containers on Technical Parameters.
