Packaging Evidence Checklist | UD Packaging

← Plastic Materials Guide

Packaging Evidence Checklist

Build an evidence chain from resin identity to a representative unit load.

Confirm all five evidence layers

1. Resin and grade evidence
Polymer, grade, additives, virgin/recycled feedstock state, batch identity and relevant data-sheet revision are recorded.

2. Converted-product evidence
Finished film or strap width, thickness, surface, orientation, sampling direction, conditioning and tensile method are tied to the reviewed SKU.

3. Joint-system evidence
Seal, weld or buckle method, equipment, settings, sample count, break mode and joint result are documented separately from strap break force.

4. Time and exposure evidence
Creep, stress relaxation, retained tension, recovery, temperature, humidity, chemicals, storage duration and load dwell are addressed for the use case.

5. Representative distribution evidence
Load geometry, mass, edges, handling equipment, restraint pattern, route hazards and acceptance criteria are reflected in a suitable unit-load test.

0 of 5 evidence layers recorded. Do not approve a material change yet.
