    {
      "question": "Does Runjia use one coating specification for every jumbo roll?",
      "answer": "silicone coating on jumbo rolls selection requires a controlled decision: That should not be assumed. Buyers must obtain the current specification and route for the exact quoted SKU."
    },
    {
      "question": "How can coating uniformity be checked?",
      "answer": "Use an agreed sampling map across reel width and production time, defined methods, individual results, limits, and a response plan for trends or failures."
    },
    {
      "question": "Is a release demonstration a laboratory test?",
      "answer": "No. A demonstration can support screening, but a controlled method needs defined samples, conditions, procedure, scale, acceptance, and records."
    },
    {
      "question": "Why does curing matter?",
      "answer": "Curing conditions can influence the state and behavior of a coating, so the supplier should define controls, monitoring, release decisions, and deviations."

    {
      "question": "What changes should trigger reapproval?",
      "answer": "Material, formula, paper source, coat side, key process window, equipment route, facility, test method, or other agreed risk changes may require review."
