Eyelets are usually used to close bags of pasta and biscuits using mechanical or pneumatic eyelets.

The 9mm diameter, 7mm diameter and Type 051 eyelets are certified eyelets for eyelet machines, chosen after years of experience in repairing eyelet machines.
This type of eyelet is specific for mechanical pedal and pneumatic pedal eyelets.

It is recommended to use only quality eyelets with a diameter of 9mm, a diameter of 7mm and Type 051.
Poor quality eyelets, imported and with manufacturing defects, can have material residues that scratch, wear and damage the punches and rivets of the machines, causing damage to machine downtime.
Machines that are used with unsuitable materials, in addition to being subject to breakage, could lose the warranty.
The same eyelets can also be used for manual use.

The flat head of the 9mm diameter and 7mm diameter eyelets does not cut into the sealed material, a very important detail for use on soft or limited thickness products.

The most commonly used standard eyelet on food packaging such as pasta and biscuits is the 9mm diameter (with guarantee writing).
Also available are eyelets with a 7mm diameter and Type 051 (9.5mm head – 5.5mm internal diameter).
