Several Types of Drug Packaging Tests (Part 2)

      Pharmaceutical packaging testing organizations for Pharmaceutical Packaging Inspection , detection methods typically vary depending on the type of packaging. So, do you know Pharmaceutical Packaging Inspection What are the different forms available? In the pharmaceutical industry, common packaging formats include blister packs, strip packaging, bag packaging, double-aluminum packaging, plastic packaging for water-based injectables, and soft-bottle packaging, among others.

Summarizing China's and international relevant standards and specifications, for Pharmaceutical Packaging Inspection The key indicators for material testing and control include barrier performance, mechanical properties, smoothness, thickness, solvent residues, sealing performance, cap torque, headspace gas analysis, and print quality, among others. Pharmaceutical Packaging Inspection This primarily refers to performing barrier property tests on pharmaceutical packaging materials using testing instruments—such as gas permeability testing and water vapor transmission rate testing.

"When taking medication, it's common for people to peel off that "tin foil"-like material—some even find it surprisingly relaxing and comforting. But have you ever wondered what exactly this "tin foil" is made of, and why it’s used in the first place?"

This type of pharmaceutical packaging is called blister packaging. The main materials used in blister packaging are medicinal PTP aluminum foil, rigid plastic sheets (polyvinyl chloride PVC), and adhesives. Today, Xiaomin will take you to learn more about it. Medicinal aluminum foil.

• Leachable substances

The right material can minimize the impact of leachable components on the quality and safety of pharmaceutical products.

Xiaomin on Testing: Certain leachables may affect the drug’s components, potency, or even medical diagnostic tests. Additionally, the accumulation of some leachables could alter the drug’s spectral properties, such as UV absorption or color changes. They may also lead to increased impurity levels or the formation of particulate matter.

• Fluorescent agent

Aluminum foil may be coated with a protective layer or adhesive, primarily to check whether the adhesive contains fluorescent agents.

Xiaomin on Testing: This test can determine whether aluminum foil contains fluorescent substances, which are mildly toxic. If a leak occurs accidentally and the substance is mistakenly inhaled or comes into contact with skin, it could lead to health issues such as nausea, dizziness, paralysis, or even loss of consciousness.

• Volatiles

Under standard conditions, the mass reduction of aluminum foil after being heated to extremely high temperatures in an air-tight container—minus any water content—represents the volatile substances it contains.

Xiaomin on Testing: The aluminum foil production process may involve coating with silicone oil, and impurities in the silicone oil could contain other volatile substances.

• Microorganisms

To examine the types, quantities, and characteristics of microorganisms in aluminum foil, as well as their potential impact on human health, in order to determine compliance with quality standards.

Xiaomin on Testing: Primarily focuses on monitoring the environment and personnel health during aluminum foil production to ensure no contamination occurs in the final product.

• Abnormal toxicity

Abnormal toxicity differs from the inherent toxicological characteristics of the drug itself; instead, it refers to toxicity introduced during the manufacturing process or caused by other factors.

Xiaomin on Testing: Improper selection of packaging materials during abnormal toxicity studies led to drug contamination, ultimately affecting biological and physiological outcomes.

• Dimensions and Tolerances

Dimensional deviations—such as length, width, thickness, and heat-seal width—must all remain within the specified tolerance ranges.

Xiaomin on Testing: This is an important technical indicator for determining whether aluminum foil affects the overall aesthetics and functionality of packaging materials—and in recent years, it has also become A test that customers place great importance on.
