What are the production requirements of medical breathable tape

Summary: The production of medical tape mainly uses two parts, the substrate and medical pressure-sensitive adhesive, through the adhesive groove, squeegee and fabric rollers will be through the substrate coated with medical pressure-sensitive adhesive, and then into the oven pre-drying, and then the use of high-pressure air to make the medical tape to form a small breathable holes, and then completely dry, after drying by the reeling device can be rolled up. When producing medical tape, attention should be paid to meet the production requirements of safety, functionality and comfort. Below to learn about the production of medical tape step by step process. First, the medical tape production step process

Medical tape is a medical pressure sensitive adhesive coated in non-woven fabric, PE material and other substrates to produce a tape, the specific production steps are as follows:

1, the substrate from the fabric unwinding device.

2. The substrate passes through an adhesive groove, a squeegee and a fabric roller, and the solvent-based medical pressure-sensitive adhesive in the adhesive groove is squeegeed and coated on the front side of the substrate.

3, the substrate scraped with solvent-based medical pressure-sensitive adhesive into the pre-heated oven for pre-drying.

4, relying on the control of the front and rear pressure rollers, the tape treated in step 3 is tensioned on the hollow metal device, high-pressure air is blown out from the microporous holes on the hollow metal device, and high-pressure air is blown out from the back side of the substrate, and before the solvent-type medical pressure-sensitive adhesive is completely dried, the high-pressure air is blown out from the back side of the substrate, so that the front side of the substrate forms a densely distributed tiny ventilation holes of the medical pressure-sensitive adhesive.

5, and then into the oven drying, so that the medical pressure-sensitive adhesive in the solvent completely evaporated.

6, finally, by the winding device for the dried medical tape winding.

Second, what are the production requirements of medical breathable tape

Medical breathable tape is used in the medical field, so it has high production requirements, the production requirements of medical tape are:

1, safety

Safety is crucial for medical products, especially those in direct or indirect contact with the human body, its safety is mainly reflected in the environmental protection, biocompatibility, biocompatibility, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety, safety. Its safety is mainly reflected in the environmental protection, biocompatibility, production process stability and traceability and other aspects. For key process parameters, it is usually required that the process capability index (CPK) is >1.33, and can be traced back to any batch of raw materials used in any batch of product batch, operators, equipment parameters and other related information through the LOT number, so as to carry out the investigation of the problem and improvement.

2, functionality

Medical tape functionality, simply put, is to stick well, for medical breathable tape, the main performance in 3 points:

(1) whether the adhesion of the material is sufficient: when the tape needs to stick the material and the skin phase (such as for surgical towel), the tape should be able to firmly adhere to the skin surface.

(2) Appropriate adhesion to skin: Since most medical tapes need to be applied to the skin, they should have appropriate adhesion, not the stronger the better.

(3) Whether it can adapt to the appropriate sterilization method: different sterilization methods have different effects on product performance, the selection of materials suitable for product sterilization method is an important part of product design.

3, comfort

The comfort of medical products, with the improvement of medical level, more and more attention by health care workers and patients. For the use of medical tape for medical products, tear down whether the pain, whether there will be residual adhesive, compliance and elasticity of how to stick with the patient's intuitive feeling of boredom, etc., are the specific embodiment of the comfort of the medical tape. How to transform these items into quantifiable, testable indicators, is the important task of medical tape manufacturers.
