Фармацевтическая упаковка Цвет Жесткая ПВХ пленка

Pharmaceutical packing color rigid PVC film is a packaging material that combines the performance of traditional PVC rigid films with color printing technology. It is widely used in aluminum-plastic packaging of solid preparations (such as capsules and tablets).

Specification of colored rigid PVC film for pharmaceutical packaging:

– материал: Поливинил хлорид (ПВХ) is used as the base material, and color effects are achieved by adding pigments or dyes while maintaining the physical and chemical properties of PVC.

– Common thickness: 0.2мм, 0.3мм, 0.4мм, 0.5мм. The thickness selection will affect the strength, molding performance and sealing of the blister.

– Width and length: Generally provided in the form of rolls or sheets, the width is usually between 200mm and 1200mm, and the length can be customized according to customer needs.

– цвет:

Colored rigid PVC films can provide a variety of colors, the most common ones are transparent, синий, зеленый, красный, желтый, и т.д. The color can be customized according to customer needs.

Performance characteristics of pharmaceutical packing color rigid PVC film:

– Transparency and color performance:

Colored rigid PVC film can achieve rich colors (such as red, синий, зеленый, и т.п.) through printing or co-extrusion process, which improves the recognition and aesthetics of pharmaceutical packaging.

– Барьерная собственность:

Good moisture and dustproof performance, protecting drugs from external environment.

– Температурная стойкость:

Stable within the common temperature range of drug packaging (such as room temperature to 60℃).

– Механическая сила:

High tensile strength and impact resistance, suitable for automated packaging equipment.

Quality standards and technical requirements

Colored PVC rigid films must meet the following requirements:

– вид: No defects such as cracks, perforations, бугорки, морщины, oil stains, и т.д.

– The number of impurities such as crystal points and black spots is strictly limited (such as no more than 3 crystal points per 100cm²).

– The color layer must be uniform and consistent, without color difference or fading.

Физические свойства:

– Thickness and width: meet the allowable difference of specifications (such as width ±1mm, thickness ±allowable range).

– Предел прочности: longitudinal and transverse average values ≥44MPa.

– Heat sealing strength: strength after heat sealing with aluminum foil ≥15mm.

– Water vapor permeability: ≤ specified value (specific values must be based on pharmacopoeia or enterprise standards).

Chemical and microbiological requirements:

– Vinyl chloride monomer content: ≤ 1 part per million.

– Microbiological limits: Total bacteria ≤ 1000/100cm², mold ≤ 100/100cm², Escherichia coli and live mites shall not be detected.

– Dissolution test: Must meet indicators such as clarity and heavy metals (such as n-hexane non-volatile matter ≤ specified value).

Application scenarios

Pharmaceutical packaging field:

Solid preparation aluminum-plastic blister packaging: Colored PVC rigid films are compounded with aluminum foil and used to encapsulate tablets, капсулы, и т.п., which are both protective and aesthetic.

Advantages of Фармацевтическая упаковка Цвет Жесткая ПВХ пленка:

– High recognition: Color design helps consumers quickly identify the type of medicine (such as different colors corresponding to different doses or specifications).

– Cost-effectiveness: Compared with other high-performance packaging materials (such as PET/PE composite films), colored PVC rigid films are relatively low in cost and suitable for large-scale production.

– Защита окружающей среды: Some companies have developed recyclable or biodegradable colored PVC films.
