In industrial converting, material selection is a critical engineering decision. A die-cut or laminated part performs very differently depending on whether it is built on a polyimide film, an acrylic foam, or an HDPE non-woven<\/strong>. Each substrate carries specific physical, thermal, chemical, and mechanical properties \u2014 and the major brands in the space, DuPont, 3M, Rogers Corporation, Sekisui, have established their product names as the default references in industrial specifications worldwide.<\/p>\n

It is available as thin films (from a few microns to several hundred), adhesive tapes, and custom die-cut parts.<\/p>\n

Technical Properties<\/h3>\n

 <\/p>\n

Kapton\u00ae operates continuously from \u2212269 \u00b0C to +400 \u00b0C without significant loss of mechanical performance \u2014 a range that puts it in a class of its own. It resists solvents, ionizing radiation, moisture, and chemical agents. Its high dielectric strength makes it a first-choice electrical insulator even in very thin layers.<\/p>\n\n\n\n\n\n

Mylar\u00ae \u2014 The High-Performance Biaxially Oriented PET Film by DuPont<\/h2>\n

What is Mylar ?<\/h3>\n

 <\/p>\n

Mylar\u00ae is DuPont’s registered brand name for its biaxially oriented polyethylene terephthalate (PET)<\/a> films<\/strong> : a plastic film that has been stretched in both directions (machine direction and cross direction) to optimize its mechanical properties. It is one of the most versatile plastic films available in industrial markets. The same material is also sold under the Melinex\u00ae brand (ICI\/Teijin) for certain medical and display applications.<\/strong><\/p>\n

Technical Properties<\/h3>\n

Mylar\u00ae stands out for its high dimensional stability, low elongation, good tear resistance, and excellent printability. It handles moderate temperatures (up to around 150 \u00b0C) and resists humidity well. Available in transparent, metalized, or adhesive-backed versions, it forms the backbone of many multi-layer laminates. It is often compared directly to Kapton\u00ae or to standard polyester films depending on the application context.<\/p>\n\n\n\n\n\n

 <\/p>\n

Tedlar\u00ae is a polyvinyl fluoride<\/a> (PVF)<\/strong> film developed by DuPont in the 1960s. Its smooth, non-porous surface makes it difficult to contaminate and easy to clean \u2014 two properties that are highly valued in demanding industrial environments.<\/p>\n

Technical Properties<\/h3>\n

 <\/p>\n

Tedlar\u00ae delivers exceptional resistance to UV, weathering, and chemical agents, along with very low gas permeability<\/strong>. It retains its mechanical and optical properties after years of outdoor exposure, making it one of the most durable films on the market. Due to its premium characteristics, Tedlar\u00ae commands a significantly higher price<\/strong> than conventional films but the trade-off is substantially longer service life.<\/p>\n\n\n\n\n\n

What is Teflon\u00a0 \/ PTFE?<\/h3>\n

 <\/p>\n

Teflon\u00ae is DuPont’s registered brand for its polytetrafluoroethylene (PTFE)<\/a> products<\/strong>. PTFE is one of the most chemically inert synthetic materials in existence, available as thin films, tapes, coated fabrics, or machined parts. Its composition, entirely fluorine-bonded,\u00a0 makes it extreme across virtually all properties, and an ideal choice for any application involving aggressive chemicals or sensitive products.<\/strong><\/p>\n

Technical Properties<\/h3>\n

 <\/p>\n

PTFE combines exceptional characteristics: maximum non-stick surface, near-total chemical resistance (acids, bases, solvents), thermal stability from \u2212200 \u00b0C to +260 \u00b0C.<\/strong> Its coefficient of friction is among the lowest of any known solid. It is also biocompatible and approved for food contact. PTFE’s surface is essentially non-adhesive, which makes it a challenging substrate to bond \u2014 surface treatment (such as corona treatment) is typically required before lamination.<\/p>\n\n\n\n\n\n

 <\/p>\n

Sector Applications<\/h3>\n

 <\/p>\n

VHB\u00ae \u2014 3M’s High-Bond Acrylic Foam Tape<\/h2>\n

What is VHB ?<\/h3>\n

 <\/p>\n

VHB\u00ae (Very High Bond) is 3M’s range of high-performance double-sided acrylic foam tapes<\/strong>. More than a simple adhesive, VHB\u00ae is a viscoelastic acrylic foam capable of replacing mechanical fasteners \u2014 screws, rivets, welds \u2014 in assemblies subject to high stress.<\/p>\n

VHB\u00ae vs. Standard Double-Sided Tape<\/h3>\n

 <\/p>\n

A standard double-sided tape transfers stress directly between the two bonded surfaces<\/strong>. VHB\u00ae, thanks to its viscoelastic acrylic foam core, absorbs and redistributes stresses \u2014 vibrations, impacts, differential thermal expansion \u2014 while maintaining the assembly. This absorption capacity is what allows it to replace mechanical fasteners in structural applications.<\/p>\n

Technical Properties<\/h3>\n

 <\/p>\n

Used in industrial filtration, hygiene, non-food packaging, and agriculture (crop protection covers). Spunbond PP is the base for many lightweight medical packaging applications.<\/strong><\/p>\n

SMS (Spunbond-Meltblown-Spunbond)<\/h3>\n

 <\/p>\n

A tri-layer structure combining two spunbond layers around a meltblown core of ultrafine fibers. The central layer provides a bacterial and aerosol barrier that single-layer spunbond cannot achieve. The reference structure for sterilizable medical packaging and protective PPE (masks, surgical gowns).<\/strong><\/p>\n

Sontara\u00ae (DuPont)<\/h3>\n

 <\/p>\n

A hydroentangled non-woven based on polyester and\/or cellulose fibers. Its binder-free manufacturing process delivers high mechanical strength, exceptional softness, and very low particle emission \u2014 three essential qualities for medical, pharmaceutical, and cleanroom environments. Used in technical wipers, examination sheets, and surgical drapes.<\/strong><\/p>\n\n\n\n\n\n

Metal Substrates & Technical Papers<\/h2>\n

Aluminium & Copper Films<\/h3>\n

 <\/p>\n

Metal films, primarily aluminium and copper, form a distinct material family in converting. As thin adhesive foils or composite films, they serve two main functions: electromagnetic shielding and thermal management.<\/strong><\/p>\n

Adhesive Aluminium Film<\/h3>\n

 <\/p>\n

Used for lightweight EMI shielding, reflective thermal insulation, and protection of sensitive components<\/strong>. In automotive applications, it shields wiring harnesses, electronic control unit housings, and underhood heat screens. Its ease of processing and moderate cost make it the most common choice for first-level shielding.<\/p>\n

Adhesive Copper Film<\/h3>\n

 <\/p>\n

More conductive than aluminium, copper film is preferred for high-performance RF shielding, grounding connections, and certain power electronics applications. Also used in PCB design for ground planes and electrostatic discharge (ESD) protection. Its higher cost limits it to applications where maximum conductivity is required.<\/p>\n\n\n\n\n\n

Implementation at ATE<\/h4>\n

Rotary die-cutting and lamination of adhesive aluminium and copper films for EMI shielding, thermal protection, and electrical connections in the automotive and electronics sectors.<\/p>\n

Technical & Kraft Papers<\/h2>\n

Technical papers cover a broad spectrum in industrial converting. Unlike standard printing papers, they are engineered to meet specific requirements in terms of strength, barrier properties, or compatibility with industrial processes.<\/p>\n

Kraft Paper<\/h3>\n

 <\/p>\n

Kraft paper (unbleached or bleached) is one of the most common substrates in converting. Strong in tear and tensile strength, it is used as a protective interleaf between metal parts, as a silicone-coated liner for labels and pressure-sensitive adhesives, and as industrial protective packaging for machined parts and components.<\/p>\n

Specialty Papers<\/h3>\n
