Embodiment Construction

[0016] The production process of medical sterilization three-dimensional roll bag includes the following steps:

[0017] a. Glue preparation: Weigh the polyurethane adhesive and ethyl ester with a platform scale, and mix it with the blue pigment weighed by the balance at a ratio of 2:3:0.1, and put it into the glue mixing bucket and stir evenly;

[0018] b. Dry compounding: According to the requirements of the production process sheet, receive polyester rolls, polypropylene rolls and glue, put the polyester rolls on the unwinding frame in the middle of the dry compound machine, and fix the polypropylene rolls on the unwinding machine in front of the machine On the bracket, use the version roller to evenly coat the glue on the corona surface inside the polyester roll, heat it in the oven to bond with the polypropylene sheet, squeeze and dry through the extrusion roll, and wind up to form a blue Film roll;

[0019] c. Curing: Send the dried blue film roll to the curing room and...

Abstract

The invention discloses a production technology of medical sterilization three-dimensional roll bags. The production technology includes the steps of glue solution preparation, dry lamination, curing, slitting, curing, printing, bag manufacturing, finished product inspection, warehousing and the like. The production technology has the advantages of being simple in preparation technology and simple and convenient to operate; in the glue solution preparation process, a glue solution is clear and free of sundry, and therefore convenience is brought to the next printing step. The rolled and sealed edges of the roll bags manufactured through the technology are free of opening, free of split, easy to tear and free of paper scrapes after being torn. After sterilization is conducted on the packaging bags, adhering between articles contained in the packaging bags and the packaging bags can be avoided.
