Problems solved by technology

[0003] Nowadays, it is advocated to use degradable materials to prepare packaging bags. Many of them use polylactic acid and other ingredients. Although they have a degradable effect, the cost is relatively high.
At the same time, in the field of food and other packaging, materials are required to have a good antibacterial effect, and silver ions and oth

Example Embodiment

[0033] Example 1:

[0034] like figure 1 , figure 2 and image 3 As shown, a method for making a packaging bag includes the following steps:

[0035] Step 1, making a gravure plate: according to the standard version of the pattern to be printed, place the pattern of the same color on the same gravure plate, and the depth of the gravure plate groove is preferably 10 μm;

[0036] Step 2, modulate the ink: according to the standard version of the pattern to be printed, modulate the ink of the corresponding color according to the color sample in the pattern;

[0037] Step 3, installation equipment: install the gravure produced in step 1 on the printing device, place the ink of the corresponding color of the gravure in the ink cartridge of the printing device, and place the packaging film to be printed at the starting position;

[0038] Step 4, printing: The unwinding traction mechanism starts to pull the packaging film at a preset speed, and the real-time tension of the packa...

Abstract

The invention discloses a packaging bag manufacturing method. The packaging bag manufacturing method comprises the ten steps of gravure manufacturing, ink preparing, equipment installing, printing, energy-saving drying treatment, printing pattern detection, composite working procedures, drying and curing, slitting and bag making, wherein an energy-saving drying heat pump set is used in the step ofenergy-saving drying treatment; according to the step of printing pattern detection, a stroboflash lamp irradiates a packaging film to obtain synchronous static patterns; and a solvent-free compounding mode and specially-made glue are adopted in the step of composite working procedures. Printing equipment is stable in operation process, consistent in speed, uniform in printing and good in printing effect. The energy-saving drying heat pump set is used, so that lost heat is recovered, and the energy is saved. The solvent-free compounding mode is adopted, so that solvents are prevented from volatilizing and polluting the environment. The curing condition is changed, so that a packaging bag has a high-temperature-resistant effect, the performance of the packaging bag is improved, and the application range of the packaging bag is enlarged.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a method for making a packaging bag. Background technique [0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. Widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are finally transported to landfill areas for disposal like general garbage, and only 7% of plastics are recycled. [0003] Nowadays, it is advocated to use degradable materials to prepare packaging bags. Many of them use polylactic acid and other components. Although they have a degradable effect, the cost is relatively high. At the same time, in the field of food and other packaging, materials are required to have a good antibacterial effect, and silver ions and other substances with a bactericidal effect are often added, and heavy metals will be prec...
