This document profiles Jordan Robertson, General Manager of Business Development and Marketing at StackTeck Systems Limited, and describes their TRIM (Thin Recess Injection Molding) technology. TRIM allows for ultra-thin wall packaging designs with thickness as low as 0.011 inches and flow length to thickness ratios of up to 520, providing weight reductions of 20-40%. An example 56 ounce container is shown to reduce weight by over 25% using TRIM. Conclusions state that lightweighting of over 40% is feasible compared to conventional designs, and TRIM is well-suited for thin-wall containers, lids, and cost-sensitive packaging.

3. TRIMTM (Thin Recess Injection Molding)
Technology Review:
 Thin panels cover 50-90% of part area
 Ultra-Thin beyond conventional designs
 20%-40% weight reduction
 Patent pending
 First commercial application
 Aesthetic effect of 90% coverage
Agenda: TRIM Ultra-Thin Part Design

4.  Lightweighting for thinnest, lightest possible part
 “L” is length of flow
 “T” is average thickness
 “L/T” is abstract measure
 PP food tubs typically have:
L/T = 260-300
Thinwall Packaging
Basic Principle
“L”
