Pharmaceutical polyethylene film bag heat sealing strength tester

Heat sealing strength, in simple terms, refers to the tensile strength that the sealing part of a medicinal polyethylene film bag can withstand after heat sealing, usually measured in N/15mm. This value may seem abstract, but it directly reflects the firmness and sealing performance of the film bag seal. Imagine that the medicinal polyethylene film bag is like a "sealed compartment" guarding the medicine, and the heat sealing strength is the "sturdy lock buckle" of the compartment door. When the heat sealing strength meets the standard, the "lock buckle" is tightly engaged, and "unwelcome guests" such as air, moisture, and microorganisms from the outside cannot enter the "sealed chamber". The drug can maintain its quality and efficacy in a stable environment.

During the storage and transportation of drugs, packaging is subjected to various external forces such as compression, collision, friction, etc. If the heat sealing strength is insufficient, the sealing part may crack or detach under the influence of these external forces, just like the lock buckle is not secure and the cabin door is easily opened. Once the packaging is damaged, the drug will be exposed to the external environment and face many risks. For example, oxygen in the air can oxidize drugs, leading to the decomposition of active ingredients and reducing their efficacy; Moisture can cause drugs to become damp, leading to reactions such as mold growth and hydrolysis; The invasion of microorganisms may cause drug contamination and lead to serious health problems.
