Record food loss, residue, liner tearing and handling separately, with an accepted reference tested alongside. Define sampling and acceptance before the trial.

  "quickTakeaway": "This trial suits dim sum producers, central kitchens, frozen-food manufacturers and foodservice distributors selecting liners for a known application. If the buyer distributes to several food producers, separate their conditions rather than claiming one result covers all recipes. Start with the application most likely to expose the complaint.",

      "heading": "How should removal be observed?",
      "answer": "Define whether the food is lifted, the paper is peeled, or a mechanical transfer separates them. Keep angle, speed and support reasonably consistent for the agreed method. Photograph the food underside and removed liner. Record paper tears, visible fibres, food residue and unacceptable food damage separately; a single overall good-or-bad score hides the failure mechanism."

      "heading": "What comparison helps identify a genuine improvement?",
      "answer": "Run the accepted liner under the same conditions and record both outcomes before discussing price. Repeat agreed trials where variation is material. A better result with one recipe should not be generalized to oily fillings, frozen storage or a different steaming process without evaluation.
