Pharmaceutical Aluminium Foil Printing Ink — Chemi HR AL Series | Bangladesh

Machine Specification

Why pharma foil ink is a specialty product

Aluminium foil for pharma blister-packs is not a standard printing substrate. The blister-sealing process applies temperatures of 150–180°C to bond the foil onto the plastic blister; the ink has to survive this heat without smudging, discolouring or losing adhesion. Standard inks fail at this temperature — either the ink discolours (yellows or darkens) or it smears as the foil deforms under the sealing head.

Chemi HR AL is heat-resistant to well above blister-sealing temperatures, holds colour without discolouration, and adheres to the aluminium foil surface reliably through the full production and shelf-life cycle. It also meets pharma-grade migration compliance — critical because the printed foil is in direct contact with the tablet inside the blister pocket.

Applications

The primary customers are pharmaceutical companies packaging blister-pack tablets and capsules (Bangladesh’s pharma sector is one of the country’s fastest-growing categories — Beximco, Square, Renata, Incepta, ACI, Aristopharma, plus contract packaging for international brands). Secondary applications include pharma sachet packaging (single-dose powders, ORS packets), specialty pharma pouches (multi-tablet daily packs), and pharma foil laminated packaging.

For pharma converters or in-house pharma packaging lines, Chemi HR AL Foil is one of the standard specification inks — buyer compliance and regulatory documentation are already in place, cutting the approval time compared to generic foil inks that would need custom compliance testing.

Frequently Asked Questions

What sealing temperatures can the ink withstand?

Chemi HR AL is heat-resistant well beyond typical blister-pack sealing temperatures (150–180°C). No discolouration, smudging or adhesion failure under standard sealing conditions used in Bangladesh’s pharma industry.

Is it compliant for direct-contact pharma packaging?

Yes — Chemi HR AL meets pharma-grade migration compliance for direct contact with tablets in blister packs. Compliance and regulatory documentation is available on request for your quality control team.

What printing method does it use?

Roto-gravure is standard for pharma foil printing in Bangladesh — Chemi HR AL is formulated for this method. Flexographic can work for some applications but roto-gravure gives the sharp text reproduction that pharma packaging (tablet names, batch numbers) requires.

What colour options are available?

Standard pharma text colours (black, blue, red for warnings), plus full colour range for brand-name and packaging graphics. Matched brand-specification colours available on order.

Does the printed foil survive the full tablet shelf-life?

Yes — colour, text sharpness and adhesion all remain stable through typical pharma shelf-life periods (24–36 months depending on the drug category). This is one of the standard ink test criteria for pharma foil qualification.

What is the delivery time in Bangladesh?

Standard colours ship within 3–7 days from Dhaka stock. Custom brand-specification colours or specialty pharma formulations from Chemicoat take 30–45 days lead time.
