Customer:

anonymous

Product:

shopping bags

Resin Type:

HDPE, include 29% recycled resin

Process:

blow film

Filler Type

5% CaCO3 Masterbatch (calpet)

Customer concerns:

Tests Brief: Control Cell : use 29% recycled resin purchased from outside
Test Cell: use 34% recycled resin purchased from outside + 0.2% TK-1
Tests Result: 1. acceptable physical and mechanical properties, even better cosmetic, glossier film appearance
2. able to lower down extruder temperature setting by 10 degree C and therefore save electric power
3. extruder speed/velocity output 10.5% increase, therefore production throughput increased from 190 kg/hour to 210 kg/hour
4. better pigment dispersion
Cost Analysis

estimate the annual saving due to higher productivity and use higher percentage of recycled or off-grade resins will be up to US$ 525,000.
