Problems solved by technology

[0006] Ordinary coating process can't prepare release paper with imitation watermark pattern, but usually to prepare release paper with imitation watermark pattern, generally use the bottom paper with watermark effect itself, but this kind of bottom paper is better than ordinary greaseproof paper The price is more expensive, and for different imitation watermark patterns, it is necessary to prepare the base paper with the corresponding watermark pattern first, which will greatly increase the production cost

Abstract

The invention discloses a preparation method of release paper with a simulated watermark pattern, which comprises the following steps of: firstly, manufacturing a printing roller; secondly, preparing a release agent: the release agent comprises 1 part by weight of silicone oil, 8 / 1000 parts by weight of catalyst, 3-6 parts by weight of food special organic solvent, the catalyst is a noble metal catalyst, and the food special organic solvent is No. 6 solvent oil or edible aromatic hydrocarbon; thirdly, printing the watermark pattern: installing the manufactured printing roller on a printing press, taking the release agent as printing ink and printing the watermark pattern on greaseproof paper; and fourthly, drying: drying the printed release paper in a drying tunnel, ensuring that the temperature of the drying tunnel is 80-120 DEG C, the air quantity in the drying tunnel is 7000-9000 m3 / h, and the drying time is 15-30s and obtaining the release paper with the simulated watermark pattern. The preparation method has simple process and lower cost; and the prepared release paper with the simulated watermark pattern can fully satisfy the demands of food packaging.

Description

technical field [0001] The invention relates to the fields of food packaging and release paper, in particular to a method for preparing release paper with imitation watermark patterns. Background technique [0002] At present, the commonly used release paper in food packaging is made by coating an anti-adhesive substance on the bottom paper, the bottom paper is generally oil-proof paper, and the anti-adhesive substance is generally silicone oil. [0003] Grease-proof paper itself has many fiber bonding points, low porosity and high transparency, which can prevent oil penetration and absorption, and is widely used in food packaging and processing fields such as food liners, steaming, microwave, and freezing. However, if the food is packaged with oil-proof paper alone, the food is easy to stick to the oil-proof paper, so it is necessary to apply anti-sticking substances such as silicone oil on the oil-proof paper. [0004] Silicone oil is often used to coat the surface of foo...
