The national quality inspection standards for condoms are divided into length, width, burst capacity and burst pressure, storage period, pinhole test, packaging and marking. But for the average consumer, it is a practical and feasible way to identify the quality of a condom from the condom packaging mark.
Good condom packaging will not use very explicit patterns, and the patterns and fonts printed on the condom packaging film are also very clear and beautiful. Good condom packaging is marked as recommended by the China Family Planning Commission.
The size of the condom package is written, probably in the middle of the back of the box. You can pay attention to it.
Condoms are generally available in four sizes: large, medium, small, and extra small. The width of a large condom is 54 ± 2 mm ( diameter 35 mm ) , and the width of a medium condom is 52 ± 2 mm ( diameter 33 mm ). The width of the small condom is 50 ± 2mm ( diameter 31 mm ) , the extra small condom is 48 ± 2mm ( diameter 29 mm ) .
Another point is to pay attention to the shelf life of condoms. Some people think that the freshest the condom is like food, the better, but it is not. The condom just produced is kept in a sealed package by adding lubricant. At this time, the chemical properties of the latex determine its poor elasticity and texture. Generally, after half a year to one year of storage , the chemical bond of the latex is partially broken , and there is a certain degree of physical or chemical reaction with the lubricant . At this time, the sleeve reaches the best state in terms of texture or elasticity.
The material of condom packaging film is generally PET / AL / PE . Aluminum foil is used. Has good barrier properties and easy tearing.
