Practical answers to real thermoforming and packaging engineering problems.
Technical notes from real manufacturing, testing, material selection and packaging development experience. Each note is the full engineering version of a KONIX Packaging Notes post — one question, a direct answer, and the test conditions behind it.

Latest Engineering Notes
PACKAGING NOTES #004MaterialsSame Property Name, Different Numbers — Can You Compare Two Material Datasheets?
One datasheet says 27 MPa, another says 496. Which material is stronger? Wrong question. Three checks before you put two supplier TDS side by side.
PACKAGING NOTES #003ESD & Static ControlLower Is Not Always Better — Choosing the Right Surface-Resistance Band for an ESD Tray
"Give me your most conductive tray" sounds logical, and is sometimes right — but not for the reason most people think. What each resistance band actually does, and four questions to ask before approving a thermoformed ESD tray.
PACKAGING NOTES #002Quality & TestingThe Tray Passed QC on Friday and Failed on Monday. Why?
Thermoformed plastic keeps moving after demould. When supplier and customer measure the same tray on different days, both records can be correct — and both can disagree.
PACKAGING NOTES #001Tray Design & DFMHolding the Product Is Only Step One — What a Tray Design Review Should Actually Check
A tray can fit the product perfectly, pass the approval meeting, and still fail three months later. These are the questions a design review should ask before the drawing is released.
ESD & Static Control
Surface resistance, conductive versus dissipative, humidity effects and test conditions.
Materials
PET, PP, PS, HDPE, ABS, PVC and PE — selection, behaviour and trade-offs in thermoforming.
Tray Design & DFM
Draft angles, undercuts, nesting, stacking and designing trays that a machine can actually pick from.
Quality & Testing
Inspection timing, measurement conditions, validation and why a passing part can fail later.
