Raw materials
Quality indentation lines are produced with better quality raw materials and products are more uniform. The poor quality of the indentation line uses inferior raw materials, making it difficult to improve the performance of the product. If the protective tape of the bottom mold, in order to ensure that the quality of the protective tape can meet stringent requirements, the high-quality indentation line manufacturer has not purchased from the tape production plant because the general tape is not suitable for the production of the indentation line, and the adhesive tape The error range cannot meet the requirements. Therefore, the strong indentation line manufacturer will specially set up a tape production line to produce adhesive tapes for indentation lines. In general, indentation line manufacturers obviously do not have the strength to invest in a professional tape production line. They often store ordinary tapes for indentation line production from the market, and indentation lines produced using such materials. The quality can be imagined.
