Papel de aluminio PTP para embalaje de tabletas

El papel de aluminio PTP es un material central para los envases tipo blíster farmacéuticos., favorecido por sus altas propiedades de barrera, facilidad de procesamiento y seguridad, lo que la convierte en la solución preferida para envases de tabletas sellados individualmente. PTP aluminum foil for tablet packaging uses plain aluminum foil as the base material, procesado a través de la impresión de gráficos, revestimiento con una capa protectora OP, y aplicando adhesivo VC. Its typical structure is OP/AL/VC, namely protective layer/aluminum foil/heat-seal layer, with a thickness generally around 0.024mm.

Tablet packaging PTP aluminum foil employs a five-layer composite structure, with each layer having a clear function:

– Protective Layer (OP):

Located on the outermost layer, it enhances the aluminum foil’s abrasion resistance and stain resistance, ensuring clear and durable printed patterns.

– Outer Printed Layer:

This layer prints drug information (such as name, dosificación, and production date) using an electro-engraved or laser-printed plate. Some products utilize invisible fluorescent anti-counterfeiting technology, displaying anti-counterfeiting marks under ultraviolet light to prevent counterfeiting.

– Aluminum Foil Base Material (Alabama):

 Primarily made of 8011-H18 aluminum alloy, con un espesor de 0,016-0,04 mm, combining mechanical strength and flexibility. Its dense metallic crystal structure effectively blocks oxygen, vapor de agua, y ligero. Oxygen transmission rate is ≤0.1cm³/(m² · 24H · 0.1MPA), and water vapor transmission rate is ≤0.5g/(m² · 24h), ensuring drug stability.

– Inner Printed Layer:

In direct contact with the drug, it must meet food-grade safety standards to prevent contamination.

– Heat-Sealing Layer (VC):

Utilizes a modified polyethylene coating with a heat-sealing temperature of 100-120℃. After bonding with PVC, PVDC, and other plastic rigid sheets, the peel force remains stable at 6-10N/15mm, achieving a strong seal and easy removal.

Core performance advantages of Papel de aluminio PTP for tablet packaging:

– Propiedades de alta barrera:

The aluminum foil layer completely isolates light, oxígeno, and water vapor, preventing drug oxidation, moisture absorption, or photodegradation, extender la vida útil de la plataforma 3 años.

– Mechanical stability:

los 8011 aluminum alloy substrate is heat-resistant, low-temperature resistant, and corrosion-resistant, suitable for high-speed automated packaging lines (speeds up to hundreds of blister packs per minute), and is not easily damaged during transportation.

– Processability:

Supports precision cutting (width ±0.2mm, length ±0.3mm), and custom-designed grooves can be used to secure micro-tablets or pellets, preventing breakage from impacts.

– Excellent printability:

Can be printed on one or both sides as needed, with rich colors and clear patterns. Capable of printing 1-12 colores, facilitating the display of drug information and corporate promotion.

– Seguridad:

Production must be completed in a 100,000-300,000 class GMP cleanroom, complying with YBB national standards and FDA and CFDA certifications. No tóxico e inodoro, ensuring no contamination of the drugs.

PTP aluminum foil is primarily used for blister packaging of tablets, cápsulas, supositorios, píldoras, etcétera, and also for blister packaging of small granular foods such as chocolate beans and candies. además, its application in health products, productos cosméticos, and disposable medical devices is gradually expanding.

Papel de aluminio PTP, with its high barrier properties, estabilidad mecanica, procesabilidad, and safety, has become the mainstream choice for tablet packaging. En la industria farmacéutica, PTP aluminum foil is widely used in the packaging of various tablets, cápsulas, and other solid drugs, and is one of the key materials for ensuring drug safety and efficacy.
