Different tensiles such as British Schuman, British domestic 38, 40, 42, 44, 46, 48, 50 can accurately test whether the surface tension of the plastic film reaches the value of the test pen. Let the user understand this film Whether it is suitable for printing. Composite or vacuum aluminizing. Effectively control quality and reduce tool delays caused by unqualified materials. Features One-time fast-drying display solution, no need to wait, safe and non-toxic, full sealing pen cover, save time longer, not polluting, and more clearly. Replenishing recycled use, economical durable, spring piston flow path, full sealing pen cover, storage length, unpacking, set to 1 bottle of 100 ml tension test Liquid Applications The corona pen is perpendicular to the film plane, plus appropriate pressure, and draws a line on the surface of the film. A slightly smaller score is easier to draw, so it does not have to be too large; the 40, 42, 44 has a point of pressure when the pen needs to be drawn. Under normal circumstances, the initial test is the accuracy of the guaranteed amount, the need for 6 different models; if it is determined that the surface of the film is extremely small, at least 3 different models are required. Imported Schumano Electroxet pen has 31, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50 or more different tensile test pen, can accurately test whether the surface of the plastic film Reach the value of the test pen. The user clearly understands whether this film is suitable for printing, composite or vacuum aluminizing, gravure printing, offset printing, UV printing, screen printing, dressing printing, inkjet printing, dry composite, extrusion, blown film, T-type extruded film, stretch film, coating, aluminized, etc., effectively control quality, reduce the loss caused by failed material Technical Standard DRK155A: One type DRK155B: Refused   Product parameters
