Adhesive Properties of Silicone-Coated Release Liner Paper Enhanced by Atmospheric Pressure Plasma Pre- and Post-Treatment

For release-liner preparation, coating stabilization of the silicone layer on base paper often requires pre- and post-treatment. In this study, we used atmospheric pressure diffuse coplanar surface barrier discharge in roll-to-roll configuration. The results of prepared coating showed that the A4 size clay-coated paper sprayed with silicone oil (0.25–0.50 mL) gradually decreased the tape peeling force (180°) with prolonged and repeated air plasma post-treatment. Best results showing increased hydrophobicity and significantly enhanced release factor of the coating were obtained after the plasma treatment in a nitrogen atmosphere. The silicone coating on the clay-coated paper reduced the reference release force from 5.5 N/cm to less than 1.5 N/cm after the repeated silicone spraying and short nitrogen plasma post-treatment. The results of X-ray photoelectron spectroscopy and scanning electron microscopy indicate silicone curing by plasma post-treatment and pore-closing of base paper without changes of the bulk material. The aging test lasting 3 months revealed the stability of the prepared coating.

Effect of pulper consistency on stickies size distribution

Pulper consistency affects production capacity, defibering efficiency, and particle size distribution of contaminants, and in particular, stickies and inks. The effect of pulper consistency on stickies size distribution, though important, has not been studied in detail. In this project, pressure-sensitive adhesive (PSA)-containing furnish was pulped in a laboratory at 5%, 10% and 15% consistency. Results show that 15% consistency pulp produced many more small-sized stickies compared to pulps produced at 5% and 10% consistency. This is contrary to the generally accepted hypothesis and needs further investigation. Calcium carbonate, usually present in varying proportions in many recovered paper grades, is known to have some pacifying effect on stickies. A new pacifying agent prepared from silicone release liner, called desiliconized pulp (DSP), behaves like bleached virgin hardwood kraft pulp. DSP seems to have a pacifying effect similar to that of calcium carbonate. Thus, DSP may potentially replace a small amount of bleached virgin hardwood kraft pulp, with a bonus stickies-pacifying effect.

FORMULATION ANDEVALUATION OF TRANSDERMAL DRUG DELIVERY OF TORASEMIDE

A skin patch uses a special membrane to control the rate at which the liquid drug contained in the reservoir within the patch can pass through the skin and into the bloodstream. The basic components of any transdermal delivery system include the drug(s) dissolved or dispersed in a reservoir or inert polymer matrix; an outer backing film of paper, plastic, or foil; and a pressure-sensitive adhesive that anchors the patch to the skin. The adhesive is covered by a release liner, which needs to be peeled off before applying the patch to the skin. Drugs administered via skin patches include scopolamine, nicotine, estrogen, nitroglycerin, and lidocaine. Non-medicated patch markets include thermal and cold patches, nutrient patches, skin care patches (a category that consists of two major sub-categories-therapeutic and cosmetic), aroma patches, weight loss patches and patches that measure sunlight exposure.

ANALISIS KUALITAS PADA PRODUKSI LABELSTOCK KERTAS HVS DI PT “X”

PT. "X" one of the manufacturing industry engaged in the manufacture of paper labels,release liner and packaging tape, and while also receiving another product label orders. Theprocess of coating on this company using wet glue placed on release paper is then dried using adryer, so that the glue dries quickly, and then combined with certain items. In order toguarantee the quality of products, the company implemented a control chart X and R are used tomeasure the uniformity of the thickness of the glue on all sides, and the cause and effectdiagram is used to infer the cause of the difference in the thickness of the glue on labelstockproduction.With the above method, the obtained results that the Lower Control Limit 20 LimitControl Over 22, and the target of 21. Cp value of 0.19 (Cp < 1) means that the process is notcapable. While the resulting Cpk value of 0.05 (Cpk< 1), we conclude that the thickness of theglue is not capable or not of accuracy and precision. The cause of differences in the thickness ofthe glue is supposedly 5 factors, namely human factors, raw materials, machines, methods andenvironment.

A review of TTS – development, types and preparations

Transdermal Therapeutic Systems (TTS) are elastic multi-layer patches applied to the skin in order to deliver active substances into the bloodstream. One advantage of a transdermal drug delivery route over other types of medication delivery is that the patch provides a noninvasive therapy, longer duration of drug activity, and improves most of bioavailability. TTS consist of a backing layer, a drug, an adhesive, and a release liner. TTS can be divided into five basic types of systems: reservoir, matrix, microreservoir, single-layer drug in adhesive, and multi-layer drug in adhesive. In order to improve the penetration of drugs through the skin, passive and active methods are used. The researchers are constantly developing new methods of improving the delivery of drugs applied by transdermal route.
