This is how manufacturers ensure functional label solutions for demanding applications, for example in automotive, medical technology and chemicals.  &lt;\/p&gt;\n&lt;p&gt;To classify materials, the surface tension is divided into three areas:&lt;\/p&gt;\n&lt;p&gt;&nbsp;&lt;\/p&gt;\n&lt;p&gt;&lt;strong&gt;LSE (Low Surface Energy, 18\u201335 mN\/m)&lt;\/strong&gt;&lt;\/p&gt;\n&lt;p&gt;Materials with low surface energy make adhesion more difficult and require specially developed adhesives. Typical examples are: &lt;\/p&gt;\n&lt;ul&gt;\n&lt;li&gt;PTFE (Polytetrafluoroethylene \/ Teflon)&lt;\/li&gt;\n&lt;li&gt;Silicone (SI)&lt;\/li&gt;\n&lt;li&gt;Polypropylene (PP)&lt;\/li&gt;\n&lt;li&gt;Polyethylene (PE) including HDPE (High Density) and LDPE (Low Density) &lt;\/li&gt;\n&lt;li&gt;PMMA (Polymethyl methacrylate)&lt;\/li&gt;\n&lt;li&gt;Epoxy resin (EP)&lt;\/li&gt;\n&lt;li&gt;Polystyrene (PS)&lt;\/li&gt;\n&lt;li&gt;Polycarbonate (PC)&lt;\/li&gt;\n&lt;li&gt;Polyamide (PA)&lt;\/li&gt;\n&lt;li&gt;Polyurethane (PUR\/PU)&lt;\/li&gt;\n&lt;\/ul&gt;\n&lt;p&gt;&nbsp;&lt;\/p&gt;\n&lt;p&gt;&lt;strong&gt;MSE (Medium Surface Energy, 37\u201370 mN\/m)&lt;\/strong&gt;&lt;\/p&gt;\n&lt;p&gt;This includes materials with medium surface energy, where adhesion is more successful, but adapted adhesives are still required:&lt;\/p&gt;\n&lt;ul&gt;\n&lt;li&gt;TPU (Thermoplastic Polyurethane)&lt;\/li&gt;\n&lt;li&gt;PVC (Polyvinyl chloride)&lt;\/li&gt;\n&lt;li&gt;PVB (Polyvinyl butyral)&lt;\/li&gt;\n&lt;li&gt;PET (Polyester)&lt;\/li&gt;\n&lt;li&gt;PPE (Polyphenylene ether)&lt;\/li&gt;\n&lt;li&gt;PES (Polyethersulfone)&lt;\/li&gt;\n&lt;li&gt;PI (Polyimide)&lt;\/li&gt;\n&lt;li&gt;GPK (Glass, Porcelain, Ceramics)&lt;\/li&gt;\n&lt;\/ul&gt;\n&lt;p&gt;&nbsp;&lt;\/p&gt;\n&lt;p&gt;&lt;strong&gt;HSE (High Surface Energy, 290\u20132000 mN\/m)&lt;\/strong&gt;&lt;\/p&gt;\n&lt;p&gt;Materials with high surface energy generally offer very good conditions for adhesion:&lt;\/p&gt;\n&lt;ul&gt;\n&lt;li&gt;Glass&lt;\/li&gt;\n&lt;li&gt;Lead (PB)&lt;\/li&gt;\n&lt;li&gt;Aluminum (AI)&lt;\/li&gt;\n&lt;li&gt;Copper (CU)&lt;\/li&gt;\n&lt;li&gt;Iron (FE)&lt;\/li&gt;\n&lt;li&gt;Steel \/ Stainless steel (VA, Niro, Inox)&lt;\/li&gt;\n&lt;\/ul&gt;\n&lt;\/div&gt;\" href=\"https:\/\/folit.de\/en\/lexikon\/surface-tension\/\" >Surface Tension<\/a><\/li><\/ul><\/div><div class=\"wpg-list-block wpg-filter-t mix\" data-filter-base=\"t\"><h3 class=\"wpg-list-block-heading\">T<\/h3><ul class=\"wpg-list-items\"><li class=\"wpg-list-item\"><a class=\"wpg-list-item-title wpg-tooltip\" title=\"&lt;h3 class=&quot;wpg-tooltip-title&quot;&gt;&lt;span class=&quot;wpg-tooltip-term-title&quot;&gt;Thermal Transfer Printing&lt;\/span&gt;&lt;\/h3&gt;&lt;div class=&quot;wpg-tooltip-content&quot;&gt;&lt;p&gt;&lt;strong&gt;Thermal transfer printing&lt;\/strong&gt; is a widely used printing process for highly resistant and durable labels, particularly in the industrial, logistics, medical technology, and automotive sectors. It involves transferring a &lt;strong&gt;colored coating (wax, wax-resin, or resin)&lt;\/strong&gt; from a ribbon (thermal transfer film) onto the label material using heat. Depending on the application, different ribbon qualities are used: wax for paper labels, wax-resin for more durable prints, and resin for extreme resistance to chemicals, abrasion, and high temperatures. Thermal transfer printing is suitable for &lt;strong&gt;paper, &lt;a href=&quot;https:\/\/folit.de\/lexikon\/polyester\/&quot;&gt;polyester&lt;\/a&gt;, &lt;a href=&quot;https:\/\/folit.de\/en\/lexikon\/polyimide\/&quot;&gt;polyimide&lt;\/a&gt;, or vinyl labels&lt;\/strong&gt; and offers high print quality with precise barcodes, serial numbers, and logos. Compared to direct thermal printing, it is more durable because the material does not need to be heat-sensitive. The correct choice of print head, ribbon, and label material ensures optimum durability and legibility of the marking.     &lt;\/p&gt;&lt;\/div&gt;\" href=\"https:\/\/folit.de\/en\/lexikon\/thermal-transfer-printing\/\" >Thermal Transfer Printing<\/a><\/li><li class=\"wpg-list-item\"><a class=\"wpg-list-item-title wpg-tooltip\" title=\"&lt;h3 class=&quot;wpg-tooltip-title&quot;&gt;&lt;span class=&quot;wpg-tooltip-term-title&quot;&gt;Thickness Range&lt;\/span&gt;&lt;\/h3&gt;&lt;div class=&quot;wpg-tooltip-content&quot;&gt;&lt;p&gt;The &lt;strong&gt;thickness range&lt;\/strong&gt; with regard to labeling foil in the printing industry refers to the variation in thickness that is tolerated within a batch of foil material. It is an important quality characteristic, because a uniform thickness across the entire width and length of the foil is crucial for consistent printing results and the processability of the foil in printing machines. &lt;\/p&gt;\n&lt;p&gt;An excessive thickness range can lead to problems in the printing application, such as uneven ink distribution, irregular adhesion to substrates, and difficulties in performing cutting and finishing processes. Manufacturers of labeling foil therefore strive for the smallest possible thickness range in order to ensure the high quality and reliability of their products. &lt;\/p&gt;\n&lt;\/div&gt;\" href=\"https:\/\/folit.de\/en\/lexikon\/thickness-range\/\" >Thickness Range<\/a><\/li><li class=\"wpg-list-item\"><a class=\"wpg-list-item-title wpg-tooltip\" title=\"&lt;h3 class=&quot;wpg-tooltip-title&quot;&gt;&lt;span class=&quot;wpg-tooltip-term-title&quot;&gt;Transfer tapes&lt;\/span&gt;&lt;\/h3&gt;&lt;div class=&quot;wpg-tooltip-content&quot;&gt;&lt;p&gt;&lt;strong&gt;Transfer tapes&lt;\/strong&gt; are thin, adhesive-coated materials without their own carrier, used for permanent or temporary bonds in industry, electronics, medical technology, and labeling technology. They consist of high-performance acrylate or rubber adhesives, applied to a &lt;a href=&quot;https:\/\/folit.de\/lexikon\/abdeckpapier\/&quot;&gt;release liner&lt;\/a&gt; or a carrier film, and leave behind only a pure adhesive layer after application.
