Pre-coating film unknown six big advantage

A, green environmental protection.     Relative to the solvent in terms of the effect of coating, pre-coating film laminating process of excluding volatile harmful substances, no potential harm to the operator, to ask environment no pollution, and no fire hazards.     Therefore, some countries have achieved 100% application pre-coating film.     In addition, pre-coating film coated printing quality easy recycling, can easily achieve paper, membrane separation, and the type of coated printing quality are difficult to recycle.     Second, easy to operate.     Pre-coating film coated production before don't like that type of coated coating preparation of glue, also need not adjust the amount of glue in the process of production, don't need to make the drying adhesive, also don't have to undertake cleaning after work, greatly shorten the auxiliary time.     Therefore, in view of the different pre-coating film laminator equipment, configuration of up to 2 ~ 3 per class operation personnel, reduce the enterprise cost of human resources.     Three, reliable quality.     The structure of pre-coating film BOPP ( Two-way stretch polypropylene film) As the backing material, spray evenly EVA hot melt adhesive.     Relative to the coating type laminating glue, hot melt adhesive in the molten state, has the very good flow property adhesive molecules to the ink and paper of the internal diffusion ability, such as melting powder ability strong superiority.     Pre-coating film coated printing quality, therefore, not only the color reduction degree is high, strong bonding force, and in front of the composite without cleaning operation, effectively prevent the print in die cutting indentation, convex blister or take off the membrane after.     Four, energy saving province electricity.     Look from the equipment total power, without drying, at present domestic automatic pre-coating film laminating machine power generally in the range of 15 ~ 20 kw, semi-automatic pre-coating film laminating machine basic between 5 ~ 10 kw of power.     And fully automatic namely coating type laminating machine between 50 ~ 75 kw of power, the traditional bridge type semi-automatic laminating machine power up to 25 kw.     Pre-coating film equipment, therefore, the power consumption of only up to 1/3 ~ 1/2 of water-based laminating equipment.     In addition, pre-coating film laminator equipment structure is compact, cover an area of an area small, save cost.     Five, flexible after processing technology.     Because pre-coating film with print bond tightly, so still can be carried out after glazing, hot stamping, screen printing, grinding, such as technology, is very flexible.     Six, more suitable for the color such as gold and silver print.     Pre-coating film not only applies to the dark field effect of printed matter, and because of the hot melt adhesive not with gold and silver cardboard, gold, silver ink contains the composition such as copper, aluminum react.     Therefore, pre-coating film laminating process on this kind of printing quality with the coating type laminating process incomparable advantages.
