Touch membrane under a certain tension, by pressing shift holographic patterns to the surface of printing quality

On the use of touch membrane, the use of hot laminating or water-based glue joint again after coating and drying technology, the new touch film laminating in paper surface, so as to achieve a smooth touch the soft handle, special and has high transparency, to ensure that no blind spot after laminating lost. The technology suitable for use in a luxury boxes, the advanced book cover, brand paper products, etc. Widely used in the art of printing industry.

touch membrane under a certain tension, by pressing the holographic pattern is transferred to the surface of printing quality, in the process, takes root membrane guide roller, the more prone to wrinkle membrane phenomenon at this time.

and the leading cause of wrinkle membrane has the following two points.

a, winding tension is too large, makes the membrane tension is inconsistent on both ends of the roll, causing membrane. At this point, the need to carefully adjust the film roller, guide roller, the balance of the damping roller, more time-consuming. Moreover, when the next reuse, tension is inconsistent, in turn, the direction of the need to readjust the equipment. Commonly used method is in winding immediately after rewinding, to further adjust the film tension, and carries on the heat dissipation.

2, under the condition of the film itself has no quality problems appear not wrinkle membrane, a pressure on issues of wrinkle membrane. This is mainly due to the pressure when imprinted transfer membrane at the ends of the roller pressure caused by imbalance. In this case, the need to adjust the pressure cylinder pressure at the ends of the film roll, the adjustment schedule at the end of the cylinder pressure limit screw, because its medial to the wallboard, location is hidden, so you need to adjusted with feeler, pay attention to lock in a timely manner. Some of the pressure equipment for transfer printing film roll at the ends of the cylinder pressure can adjust, independent relatively more convenient. Three, touch film coated

at the film guide roller tension in the process of imbalance, will cause go film speed and stamping speed, causing membrane.

after touch film and paper laminating with touch paper tactile effect; But on the adaptability and characteristics of the function, can bring more effect.

in the use of touch membrane, using thermal laminating or water-based glue joint again after coating and drying technology, the new touch film laminating in paper surface, so as to achieve a smooth touch the soft handle, special and has high transparency, to ensure that no blind spot after laminating lost. The technology suitable for use in a luxury boxes, the advanced book cover, brand paper products, etc.

and viscous factors affecting touch film is divided into general wetting and penetration

wetting: pressure sensitive adhesive only and has good wettability glued surfaces can realize the close contact, create conditions for the physical and chemical combination

mobile and diffusion of molecules: pressure sensitive adhesive molecules to be sticky material surface movement, when the distance between the two key is less than 5 a, produces the physical and chemical combination

osmosis: rubber flow, to the grooves and the air permeability under certain pressure, make the contact area increases, the adhesive and glued materials between the mechanical bonding force is produced.

BOPP film tactility with cling film packaging market demand unceasingly, BOPP tactility film market prospect is very wide, suitable for private enterprises to invest.

touch membrane is a kind of surface has special tender tactility velvet, cortex matte film.

USES all kinds of paper printing after the required pattern color, using conventional aqueous or oily glue film devices with paper tape, after drying can achieve smooth special touch soft handle, and have high perspective dumb degrees, to ensure that after the joint print no blind spot is missing. The technology suitable for use in a luxury boxes, the advanced book cover, brand paper products, etc. Widely used in the art of printing industry.

touch membrane compared with general dumb film:

touch membrane has the following features: 1.

Had a very good friction resistance;

2。 Has the remarkable degree of colour and lustre, color without losing after laminating, in black, red on the field or a full version of dark more bright and soft;

3。 There is a special tender tactility velvet, cortex;

4。 Fog degree is high, have more special matte effect.
