[IMG: Durable Cards using Melinex polyester film]

[H1] Cards

We offer a unique range of biaxially orientated PET films designed specifically for the durable laminated cards market.  The combination of durability, cost effectiveness and simplicity of implementation has made Melinex® polyester film the number one choice in a wide range of National ID applications with over 20% of the world’s population keeping their identity secure with a card based on our products.  Other common applications for Melinex® PET card films are e-Health cards, drivers licences, mass transit ticketing, automotive key cards and many other long life applications worldwide with over 2.5 billion cards issued using Melinex® PET films in the past eight years.
[H2] What is Melinex® PET?
Melinex® is sometimes referred to as BOPET, PET or PETF. It is a biaxially oriented crystalline material with polymer chains locked together in a specific lattice structure. This means it is a much higher performing material than PVC or PETG. The structure gives it enhanced durability and excellent temperature resistance.

[H2] Melinex® PET –  a more sustainable choice for the cards industry
When it comes to product sustainability, we believe that this should be assessed holistically across the life cycle of our products and taking into account the impact on the wider value chains we operate in.   Across the life time of a card, Melinex® PET films deliver significant sustainability benefits compared to PETG, PV and PC in card laminate structures.
Melinex® has a significantly lower environmental impact during it’s production, with a low carbon foot print, low water usage and with zero hazardous materials used or produced as by products during the manufacturing process.  Melinex® card products are available with high levels of recycled content or 30% bio content further reducing the environmental impact at the start of life.
PET is the most widely recycled plastic globally, and we are actively researching ways of increasing the recycling rates of post industrial and even post consumer waste generated by the cards industry.  As Melinex® PET films are halogen free, they reduce the risk and cost of end of life options such as incineration when compared to other plastic materials often used in cards applications.
However, it is during the course of the product’s life time that Melinex® PET films deliver the biggest sustainability benefit.  Using relatively small percentages of Melinex® PET films in the final laminate structure significantly increases product life time, ultimately leading to the reduction of plastic use by the cards industry.

[H2] Melinex® PET range for cards and typical applications
[H3] Melinex® PET CORE range
The Melinex® CORE polyester film range comprises white films for the card body containing unique toughening agents to offer excellent resistance to flexure and impact.
Not only does Melinex® CORE polyester film offer class leading durability and temperature stability, it can be combined with PVC or PETG using standard lamination equipment without the need for special inks or off-line adhesives.  This flexibility to tailor the amount of Melinex® PET film in the card structure to give the optimum balance between performance and cost effectiveness is one of the key benefits when compared to alternative substrates such as Polycarbonate.
Melinex® CORE1 polyester film has one surface optimised for printing with UV curable and solvent based inks (full bleed printing possible) whilst maintaining good adhesion to overlay grade PVC and PETG.
Melinex® CORE2 polyester film is optimised to be used in conjunction with the Melinex® PROTECT overlay range and UV curable / solvent based inks (requires guilloche printing with > 40% of the card body unprinted). This combination gives the benefit of tamper evidence in the final structure as the two surfaces fuse together and cannot be separated by solvents or temperature.
[H3] Melinex® PET PROTECT range
Melinex® CORE polyester film is complemented by a range of clear, overlay films offering tamper evident credentials and a wide range of personalisation techniques.
SPO – Secure Personalisable Overlay. Suitable for personalisation via direct Dye Diffusion Thermal Transfer (D2T2) printing techniques
SRO – Secure Retransfer Overlay. Outer surface optimised to give excellent adhesion to D2T2 Retransfer printing techniques
LEO – Laser Engravable Overlay. Under development contact us for details.  In the meantime we have a range of structures offering laser engravability in PET composite cards – contact us for details.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Industrial, Manufacturing & Engineering BS: Mylar Specialty Films (mylar.com)

https://mylar.com 📍 Industry: Industrial, Manufacturing & Engineering
34 BS / 100

Mylar Specialty Films is a high-substance industrial entity that delivers genuine technical value but cloaks it in standard corporate opacity. It avoids the typical marketing ‘hot air’ of its industry but fails to provide the transparent proof paths (external links and named experts) required for a minimal BS score.

First, replace generic testimonial counts with verified links to third-party review platforms or detailed, named case studies. Second, include specific ISO 9001 or IATF 16949 certificate numbers and link directly to the Ecovadis results page. Third, add a leadership or technical team section with Person schema to bridge the authority gap. Finally, provide direct download links for the UL 969 test results mentioned in the durability claims.
