Embodiment 1

[0013] The production process of the plastic frame three-dimensional bag includes the following steps:

[0014] a. Glue preparation: according to the process requirements, weigh 3 kg of vinyl acetate, 1.5 kg of crystalline paraffin, and 3 kg of gasoline with a platform scale, put them into the sol bucket and mix them, put the sol bucket into the sol water furnace to heat and dissolve, The dissolution temperature is 80°C. After dissolving for 40 minutes, use a measuring cup to measure 80 ml of silicone oil and pour it into the sol barrel and stir evenly to obtain a glue solution. Check whether the glue solution is clear and free of impurities, whether the vinyl acetate and crystal paraffin are completely dissolved, and pass the inspection. On the tracking card, enter the next process;

[0015] b. Printing frame glue: According to the requirements of the process sheet, get the dialysis paper and the glue in step a, put the dialysis paper on the unwinding rack of the printing mac...

Embodiment 2

[0020] The production process of the plastic frame three-dimensional bag includes the following steps:

[0021] a. Glue preparation: according to the process requirements, weigh 3.5 kg of vinyl acetate, 1.6 kg of crystalline paraffin, and 3.5 kg of gasoline with a platform scale, put them into the sol bucket and mix them, put the sol bucket into the sol water furnace to heat and dissolve, The dissolution temperature is 85°C. After 41 minutes of dissolution, measure 85 ml of silicone oil with a measuring cup and pour it into a sol bucket to stir evenly to obtain a glue solution. Check whether the glue solution is clear and free of impurities, whether the vinyl acetate and crystalline paraffin are completely dissolved, and pass the inspection. On the tracking card, enter the next process;

[0022] b. Printing frame glue: According to the requirements of the process sheet, get the dialysis paper and the glue in step a, put the dialysis paper on the unwinding rack of the printing ...

Embodiment 3

[0027] The production process of the plastic frame three-dimensional bag includes the following steps:

[0028] a, Glue preparation: According to process requirements, weigh 4 kg of vinyl acetate, 1.7 kg of crystalline paraffin, and 4 kg of gasoline with a platform scale, put them into the sol barrel and mix them, put the sol barrel into the sol water furnace to heat and dissolve, The dissolving temperature is 90°C. After dissolving for 42 minutes, measure 90 ml of silicone oil with a measuring cup and pour it into the sol barrel and stir evenly to obtain the glue. Check whether the glue is clear and free of impurities, whether the vinyl acetate and crystalline paraffin are completely dissolved, and pass the inspection. On the tracking card, enter the next process;

[0029] b. Printing frame glue: According to the requirements of the process sheet, get the dialysis paper and the glue in step a, put the dialysis paper on the unwinding rack of the printing machine, put the glue ...

Abstract

The invention discloses a technology producing dimensional bags with frame adhesive. The technology comprises the following steps: a, formulating adhesive liquid, that is, weighing 3 to 5 parts of vinyl acetate by weight, 1.5 to 2 parts of crystal paraffin by weight, 3 to 5 parts of gasoline by weight with a platform balance, placing the vinyl acetate, the crystal paraffin and the gasoline into an adhesive dissolving tank, mixing the vinyl acetate, the crystal paraffin and the gasoline, placing the adhesive dissolving tank into an adhesive dissolving water furnace, heating the adhesive dissolving water furnace to dissolve the adhesive dissolving tank; b, printing the frame adhesive, that is, placing dialyzing paper on an unwinding rack of a printing press, filling the adhesive liquid obtained through the step into an adhesive plate, pouring printing ink mixed in a qualified manner into an ink fountain, adjusting the tension of a winding and unwinding roll to a preset value, starting operation, printing the front side of dialyzing paper due to traction, coating the adhesive liquid on the back side of the dialyzing paper through an offset plate, stoving with 190 DEG C to 230 DEG C high-temperature, winding and forming to obtain a frame adhesive printing roll; c, producing bags; d, inspecting bag products; and e, placing the bag products into a warehouse. The invention has the advantages that the preparation technology is simple; packing bags prepared by adopting the technology have high air permeability; no paper scrap is formed when the packing bags are torn; and after sterilization, the packing bags cannot be bonded with objects in the packing bags.

Description

technical field [0001] The invention relates to a production process of a plastic frame three-dimensional bag, and belongs to the field of flexible packaging production of medical devices. Background technique [0002] At present, the packaging bags in the medical device flexible packaging market have the following disadvantages: the packaging bags are not breathable; the packaging bags cannot be torn, and there are paper scraps after tearing; The production process of this kind of packaging bag, due to the different glue preparation process, the dissolution is not complete, the temperature is not well controlled, and other processes are affected, resulting in the quality of the produced packaging bag. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a production process of a three-dimensional plastic bag with simple operation. The three-dimensio...
