Capless Sealing Wads are used when the container is not meant for reuse and the screwable cap is made redundant. The function of the cap seal is limited to providing an airtight and spill-proof seal to the contents of the container which are meant for single use only. The aluminum foil laminate is supplied either pre-cut in container neck shape or in reel form. Where it is supplied in a reel, it is die cut online and placed onto the container neck. It is then pressed down by the seal head, the induction cycle is activated and the seal is bonded to the container.
There are many benefits of Induction Sealing Wads :
Tamper evidence
The seal on the mouth of the container cannot be removed and reinstated without leaving evident sign of tampering. This also helps in differentiating real products from spurious similar looking products.
Leak prevention/protection
Installation of induction sealing wads is widely used in the food and beverage industry to prevent leakage and also to extend shelf life. It is sometimes mandatory to seal liquid chemical products before shipping to prevent them from spilling over other shipments.
Freshness
Induction sealing wads prevent contaminants present in the environment to mix with food products, and sometimes even increase the shelf life of products.
Pilferage protectionÂ
Induction sealing wads cannot be reinstated upon removal without leaving a trace of the original wad on the mouth of the container. This helps in identifying if any pilferage has happened. Infact, Pharma companies want to purchase wads that purposely leave film or foil remnants on containers as a deliberate safeguard against tampering or counterfeiting.
SustainabilityÂ
In some applications, introduction of induction sealing wads actually reduces the container weight as the presence of seal ensures enough security so as to prevent the need for a robust neck / closure.
