What are the indicators for testing pharmaceutical composite packaging film bags? Pharmaceutical composite packaging films have strict requirements for the production environment, and there are also certain national standards for the testing of finished products. In 2015, the State Food and Drug Administration issued YBB0013202-2015 "General Rules for Pharmaceutical Composite Films and Bags", which has multiple testing standards for pharmaceutical packaging materials such as three side sealing bags, pharmaceutical middle sealing bags, self-supporting bags, and pharmaceutical composite packaging bags.
Peel strength: Peel strength is the most basic performance test for pharmaceutical composite packaging films, mainly detecting the adhesion between each layer of substrate, without any adverse phenomena such as layering, bubbles, and easy tearing under certain external conditions. It mainly includes longitudinal and transverse strength tests between layers.
Heat sealing strength: Heat sealing is also known as heat sealing. This test aims to test the tightness of the inner layer of the pharmaceutical composite packaging film after heat sealing when it is packaged into a finished product, and whether there is any difficulty in sealing or tearing at a certain heat sealing temperature. Residual amount of harmful substances: not detectable
Barrier performance: Different contents have different barrier performance required for packaging. This mainly uses precision instruments to detect accurate values for their barrier performance such as water resistance, oxygen resistance, and gas resistance.
Pressure resistance: An indicator of the resistance of pharmaceutical composite packaging film bags to external pressure during transportation, packaging, and storage.
