Problems solved by technology

The high printing temperature not only causes a higher probability of the soft bag being punctured during the production process, but also leads to a high scrap rate, and at the same time, the energy cost is also high
In addition, some products with low-temperature printing function have problems such as not being resistant to high-temperature sterilization (121°C), sterilization and decolorization, etc.

Embodiment 1

[0020]

[0021] The method for preparing the above-mentioned hot stamping foil with low-temperature printing and high-temperature sterilization performance includes the following steps:

[0022] a. Heat and melt the connecting material of the nano protective layer at 140~150°C, add additives in proportion, mix evenly to form a protective layer ink, coat it on the surface of the other side of the tape base, and heat it at a temperature of 30°C Dry to form a nano-protective layer, which requires a thickness of 1 µm, and enter the next process;

[0023] b. First, mix methyl ethyl ketone and butyl ester in a weight ratio to obtain a mixed solvent, use the mixed solvent of methyl ethyl ketone and butyl ester to dissolve the link material of the color layer (temperature 60°C), then add fillers and pigments in proportion, and grind to make For color layer inks, the pigments are required to be dispersed evenly and the fineness is less than 5 μm, coated on the surface of the nano-pr...

Embodiment 2

[0025]

[0026] Preparation process: in step a, the drying temperature is 31°C, the thickness of the nano protective layer is 2µm; in step b, the melting temperature is 59°C, the drying temperature is 78°C, and the thickness of the color layer is 2µm; the others are the same as in Example 1, and the obtained product has low temperature The total thickness of the hot stamping foil for printing and autoclavability is 16 µm.

Embodiment 3

[0028]

[0029] Preparation process: in step a, the drying temperature is 30°C, the thickness of the nano protective layer is 1.5µm; in step b, the dissolution temperature is 60°C, the drying temperature is 80°C, and the thickness of the color layer is 1.5µm; the others are the same as in Example 1, and the obtained The total thickness of hot stamping foils with low temperature printing and high temperature sterilization properties is 15µm.

Abstract

The invention belongs to the technical field of hot stamping materials, and particularly discloses hot stamping foil with the low-temperature printing and high-temperature sterilizing properties. The hot stamping foil is composed of a tape base and a thermal transfer printing layer applied to the surface of the other side of the tape base, and the thermal transfer printing layer is composed of a nanometer protection layer and a color layer which are sequentially applied to the surface of the tape base; the nanometer protection layer is prepared from, by weight, 80%-90% of bonding material and 10%-20% of auxiliary. According to the hot stamping foil, the nanometer protection layer is designed, content is printed through a hot stamping machine, and the surface of the color layer is covered with the protection layer after printing. The hot stamping foil has the advantages that printing can be conducted at the low temperature lower than 120 DEG C, and the printed content can resist 121-DEG C high-temperature sterilizing and is widely applied to printing of information such as character and pattern identifiers, drug safety codes, production dates and batch numbers on the surfaces of various medical infusion soft bags.

Description

technical field [0001] The invention belongs to the technical field of hot stamping materials, and in particular relates to a hot stamping foil with low-temperature printing and high-temperature sterilization properties and a preparation method thereof, which can be used for label printing of infusion soft bags. Background technique [0002] At present, most of the logo printing of domestic infusion soft bags adopts hot stamping technology, but the defect of high printing temperature (150°C~180°C) is common. The high printing temperature not only results in a higher probability of the soft bag being punctured during the production process, but also has a high scrap rate, and the energy cost is also high. In addition, some products with low-temperature printing function have problems such as not being resistant to high-temperature sterilization (121°C), sterilization and decolorization. Contents of the invention [0003] In order to overcome the deficiencies of the prior a...
