How to determine the merits of plaster cloth

Introduction: Plaster cloth is used more and more widely. From the original self-control to the current mechanized production, a small industry has slowly been formed. What is the quality of the plaster cloth and how to choose it? Let's take a look at the staff of the Jining St. Co., Ltd. Medical Materials Co., Ltd. today!

The first is the base cloth, the most commonly used are non-woven fabrics, spunlace fabrics, and cotton cloth and PU film, because the use of non-woven spunlaced cloth is convenient and the price is low. The difference between non-woven fabric and spunlace fabric is one of the different ways to form a net, different from cotton, the biggest difference is that the non-woven fabric is not elastic, the spunlace fabric is somewhat elastic compared to the non-woven fabric, and the skin-friendly property is better. Is a slightly higher price, regardless of what kind of cloth after the application of lint, can not afford the ball, is the new material.

Followed by the bottom paper is also called release paper, release paper is the most important is the degree of stripping is better, and then the thickness problem, according to demand can give manufacturers the thickness of the paper, the bottom of the thick paper to make the plaster cloth is quite, repeated Turnaround also sells. According to the permeability of the ointment itself, the degree of imperviousness of the release paper is selected, such as that of the glassine paper is not as good as that of the liner paper.

The most important thing is the stickiness and sensitization of the plaster cloth. Sticky and firm sticking can play the role of the plaster. Now the most widely used is the hot melt adhesive (also called medical pressure sensitive adhesive) plaster cloth, and the medical pressure of the first-line brand. Sensitive adhesives have good adhesiveness and stable quality. Some sticky cloths have good adhesiveness when they are in good or bad condition (small factory's pressure sensitive adhesives have unstable quality and low price), and the temperature control in the production process is Production technology is not in place. As for the allergy rate, none of the glue factories dare to guarantee that 100% is not allergic. As long as it is a regular manufacturer, the plastic allergy rate is very low.

The biggest shortcoming of hot melt adhesive plaster cloth is that when it is sweaty in summer, the adhesiveness is not good, and it is easy to fall off. This problem, some big glue factories are trying their best to believe that in the near future, everyone will be able to use a satisfactory plaster cloth. PU film plaster cloth is widely used in the summer, it is unique in waterproof and sweat-proof, according to their plaster application time we can choose non-woven or PU film. There are also cotton cloth plaster cloths, which are mainly used for hand-made traditional black plasters. They are neatly shaved, adding a lot of brilliance to the sales of plasters, and also save the man-hours of the slurry plaster cloth, and are deeply loved by everyone.
