Embodiment 1

[0018] A production process of a laser transfer film used for anti-counterfeiting paper for cigarette packaging, the production process comprises the following steps:

[0019] (1) Load the polyester film and molded coating into the coater. The five-section oven of the coating machine is set at 85°C, 110°C, 140°C, 125°C, and 100°C, and the 150-line electric engraved wire roller is used for coating, so that the dry coating amount is controlled at 1.0-1.4 grams per square meter. The coating speed is generally controlled at 80-100 m / min, and the coating viscosity of the coating is controlled for 25-40 seconds (Zaen 3# cup); when the coating viscosity of the coating is too high, use ethyl acetate or n-propyl acetate Thin the paint.

[0020] (2) Put the coated polyester film on the molding machine, the nickel plate of the holographic pattern required by a certain cigarette is housed on the molding machine, contact the nickel plate with the holographic pattern on the coated surface ...

Embodiment 2

[0026] A production process of a laser transfer film used for anti-counterfeiting paper for certain toothpaste packaging, the production process includes the following steps

[0027] (1) Load the polyester film and molded coating into the coater. The five-section oven of the coating machine is set at 75°C, 120°C, 135°C, 115°C, and 90°C, and the 165-line electric engraved wire roller is used for coating, so that the dry weight of the coating is controlled at 1.1-1.5 grams per square meter. The coating speed is generally controlled at 90-110 m / min, and the coating viscosity of the coating is controlled for 28-45 seconds (Zaen 3# cup); when the coating viscosity of the coating is too high, use ethyl acetate or n-propyl acetate Thin the paint.

[0028] (2) Put the coated polyester film on the molding machine, the nickel plate of the holographic pattern required by a certain cigarette is housed on the molding machine, contact the nickel plate with the holographic pattern on the co...

Abstract

The invention discloses a producing technique of films for aluminized anti-fake wrapping paper, sequentially comprising the following steps of: paint coating, holographic nickel plate stamping, aluminizing, rewinding, combining, peeling, and the like. The producing technique improves the transferring and temperature-proof performances of films, and polyester films can be reused for 3-5 times, thereby improving the economic benefit and achieving the energy-saving and emission-reducing effects. In addition, corresponding holographic patterns can be made based on requirements to play an anti-fake role.

Description

【Technical field】 [0001] The invention relates to a production process of a film for aluminized anti-counterfeiting wrapping paper. 【technical background】 [0002] Aluminized anti-counterfeiting packaging paper, which uses polyester film as the intermediate carrier, is processed on the intermediate carrier to form the required holographic pattern, and then transferred to the paper after aluminized, so that the required holographic pattern is transferred to the packaging paper. Let the wrapping paper achieve the effect of beauty and anti-counterfeiting. This kind of paper is mainly used in the fields of tobacco, alcohol, medicine, cosmetics, luxury goods, daily chemical products and other products. The film used for aluminized anti-counterfeiting packaging paper is usually called laser transfer film. The existing laser transfer film has defects such as poor transferability, relatively poor temperature resistance, and poor reusability of polyester film (ie intermediate carri...
