Embodiment 1

[0046] A production method of medical sterilization packaging comprises the steps:

[0047] a. Dry compounding of polyester film and polyethylene film to obtain a composite film;

[0048] B, curing the composite membrane and carrying out the performance test on the composite membrane after the curing according to the test standard of the composite membrane in the YBB standard, "Chinese Pharmacopoeia" and the SCHL standard;

[0049] c. Print ordinary ink and sterilization indicator ink on dialysis paper respectively;

[0050] d. Cut the composite membrane obtained by dry compounding and the dialysis paper printed with the sterilization indicator ink into a size suitable for the finished roll bag;

[0051] e. The cut composite membrane and dialysis paper are made into roll bags by means of heat sealing, such as figure 1 , figure 2 , image 3As shown, the hot knife used during heat sealing includes at least three disc-shaped knife edges 1, and there is a gap 2 between two ad...

Embodiment 2

[0055] This embodiment is further optimized on the basis of the above-mentioned embodiment, and further to better realize the present invention, the steps of implementation are as follows:

[0056] a-1. Selection and preparation of glue raw materials: main agent LH-5751A and curing agent LH-5751B are selected from Jiangsu Lihe Adhesive Co., Ltd.’s plastic-plastic retort-resistant adhesive, and ethyl acetate is selected with a purity of more than 99.70%, The LH-5751A, LH-5751B and ethyl acetate used in the glue are prepared according to the weight ratio of 5:1:6.75. When preparing the glue, the raw materials are put into the glue mixing bucket and stirred evenly;

[0057] a-2. Dry compounding of polyethylene film and polyester film: put 40μm polyethylene film and 12μm polyester film on the designated unwinding reel, the glue enters the gluing tank, and the coating roller will The glue is evenly coated on the polyester film, the pressure of the coating roller is set to 0.24MP-0....

Embodiment 3

[0059] This embodiment is further optimized on the basis of the above-mentioned embodiment, and further to better realize the present invention, the steps of implementation are as follows:

[0060] b-1. Maturation of the composite membrane: place the dry composite membrane in a drying chamber with a temperature of 40°C for 36 hours to 48 hours;

[0061] b-2. Test the composite film according to the verification index of the composite film in the medical industry: according to YBB00132002, YBB00102003, YBB00312004, Chinese Pharmacopoeia Appendix VIIIH, Chinese Pharmacopoeia Appendix XIJ, Chinese Pharmacopoeia Appendix XIC, SCHL2012007, the appearance, peeling strength and solvent of the composite film were tested respectively. Residues, heavy metals, microbial limits, abnormal toxicity, and non-volatile matter are determined. If all qualified, the next procedure will be entered, and the unqualified will be quarantined in time. specific test

Abstract

The invention discloses a production method for a medical sterile package. The method comprises the following steps that a polyester film and a polyethylene film are combined in a dry manner, and a composite film is manufactured; the composite film is cured, and the performance test is conducted on the cured composite film according to the YBB standard, Chinese Pharmacopoeia and SCHL; ordinary printing ink and sterile indication printing ink are printed on dialyzing paper; the composite film and the dialyzing paper to which the sterilization indication printing ink is printed are cut into the size matched with a finished roll bag; the roll bag is manufactured through the cut composite film and the cut dialyzing paper through a heat seal method; and the performance test is conducted on the manufactured roll bag according to related standards of ISO11607:2006, EN868 and GB / T19633. The defects that a plastic composite film of a current paper-plastic bag is prone to being layered, paper scraps can occur after the package is torn off and damaged, a sterilization indication card needs to be independently used, and the roll bag is likely to open due to insufficient heat seal strength of a sealed edge of the roll bag are overcome.

Description

technical field [0001] The invention relates to a production process of medical packaging, in particular to a production method of medical sterilization packaging Background technique [0002] It has been more than 10 years since sterilization packaging was introduced to China. Many types of sterilization packaging have appeared in the market one after another. One of the most widely used is dialysis paper / plastic composite film packaging, but there are still many problems: The plastic composite film is prone to delamination, there are paper scraps after the package is torn and damaged, the sterilization indicator card needs to be used separately, and the heat sealing strength of the edge of the roll bag is not enough to cause problems such as easy opening. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a production method of medical sterilization packaging to solve the problems of easy opening of the edge of the roll bag and the use o...
