Sample Trial and Testing Guide
A useful masterbatch trial compares a known baseline with one controlled change. It records what happened on the line and verifies whether the finished product still meets its acceptance requirements.
Record the Baseline First
Use an identified material lot and record the original formula, machine settings, output, defect level and finished-product results before adding the trial grade.
Change One Main Variable
Agree on the masterbatch grade and trial formulation. Keep other raw materials, process settings and inspection methods as stable as practical.
Observe the Process by Application
Film trials follow pressure, bubble and winding; raffia follows drawing and tape breaks; injection follows filling and cycle; sheet follows gauge and flatness; blow molding follows parison and wall distribution.
Test the Actual Finished Product
Choose tests that represent the customer's use. A stable machine run does not replace approval of the film, tape, fabric, molded part, sheet or container.
Compare Total Production Value
Review accepted output, waste, screen or tooling interruptions, energy and labor effects, converting yield, final properties and material cost together.
Request a Sample Trial Plan
Provide the baseline formula, line conditions and acceptance tests so the sample can be evaluated with clear evidence.
