Medical Packaging Materials Test
The basic functions of modern packaging include protection, convenience, and promotion. Before the packaged product reaches the hands of consumers, it must go through the process of loading and unloading, transportation, storage, display, etc., and there are many factors that can damage its content in each link, and the protective function of the same. packaged product proves that the packaging can prevent damage to the product Quantitative and qualitative damage. Convenience functions refer to filling, conveying, loading and unloading, stacking, opening, etc., which have certain requirements on the performance of packaging materials. For example, mechanical properties of materials are required to facilitate their opening and consumption. The promotion function of the packaging is mainly realized through the design of the decoration and the design of the shape. The color, pattern and style are reasonable and pleasing to the eye. This largely depends on the shape, color, texture, transparency, gloss, print compatibility, etc.
For pharmaceutical packaging, especially flexible packaging, plastic films must also have certain physical and chemical properties under the premise of having the above functions. Physical properties generally include mechanical properties, thermal properties, optical properties, and barrier properties. If barrier properties are excluded, they may be called conventional physical properties. The following focuses on physical mechanical testing of pharmaceutical packaging materials.
The mechanical property of drug pharmaceutical packaging material plays an important role during processing, transportation and shelf life and its quality directly influence the safety of drug. It includes several items as follows:
- Tensile resistance and elongation ratio
- Peel resistance between layers of complex film
- Heat seal strength
- Tearing resistance
- Impact resistance performance
- Airproof performance
- Hot shrinkage performance
- Abrasion resistance of printing works
The surface smoothness ability is a routine test item of packaging materials and we can judge the smoothness ability of packaging materials, the opening performance of the packaging bag, the speed of the packaging machine, etc., by testing the static and kinetic coefficient of friction of the surface of the packaging material.
In the field of packaging, thickness testing is one of the most familiar testing items. Through thickness measurement, the water consumption rate can be reduced to achieve the purpose of cost saving.
The tightening and opening torque of the bottle cap is one of the important process parameters for offline or online quality control. Whether this torque is appropriate has a great impact on the middle of product shipment and final consumption.
