Uflex Ltd.,
Product Detailing Pack Size Pack Format Active Ingredients Expected Shelf Life Critical Barrier Requirements Product Migration Characteristics Oxidation Behaviors Reaction to UV Light
Packaging Design – 1st Step
Laminate Structure Determination Inter Layer Bond Strength Seal Strength Coefficient of Friction (COF) Tensile and Elongation Properties Drop Test SIT & Hot Tack
Case Study – Wet Tissues
Background: Package was delaminating in the market within three
months The active ingredient was migrating to the print and was
leaching ink The customer suspected that there was alteration to the
approved spec The Laminate is Die cut inline to provide easy access to
the product for frequent use The packs are stored in ambient temperatures after
filling during the entire life cycle
Analysis - 1
Comparative Microtome Images showed Laminate Structure not same with varying layer thicknesses
Analysis -2
DSC results showed different melt curves
Testing Conditions Defined
Freeze Thaw – 1 Month Weight loss at 50° C Light Fastness Test ESCR Test 5° C – end of 1, 2, 3 Months 25° C @ 60% R/H – end of 1, 2, 3 Months 40° C @ 75% R/H – end of 1, 2, 3 Months
Design Considerations
Special Polyester was used to ensure Excellent Ink Cross linking
Chemical and Heat Resistant Adhesive used Poly Formulations to ensure OTR – 64 CC and WVTR –
4.5g compared to OTR – 92 CC and WVTR – 7g in the old laminate
SIT and Hot tack to ensure excellent Seal strength of 4.5Kgf/25mm giving high speed Machinability.
Testing to confirm consistent performance over three months in all conditions defined
Customer started Local Sourcing and stopped Imports once the product was established
