Semi-automatic thermal induction sealing machine for sealing lids

This thermal induction sealing machine works on non-metallic bottles, which must be plastic or glass, as well as cup-shaped containers. It is an upgrade for the popular airtight sealing method. Thermal induction sealing improves product quality, prevents natural moisture absorption, prolongs shelf life, adds security against counterfeiting. Nowadays, sealing installation has become essential and is widely used in the chemical, pharmaceutical, cosmetic, beverage and food industries, among others.

What is induction packaging sealing?

Induction container sealers are based on a clean, contactless container sealing system through which an aluminium lid or 'disc' is glued to the perimeter of the mouth of a container.

First of all, to seal a container by induction, it is essential to have a screw-on lid, and this cannot be metal. The induction disc/cap must already be placed inside the lid.

​

Regarding the body of the container, it is always recommended to use any plastic polymer (PP, PET, PE, etc.). For glass containers, we recommend using the conduction sealing system, also known as: thermo-sealing.

​

A cap suitable for induction sealing can be composed of the following elements (layers):

​

Internal "burr-free" plug, suitable for incorporation of aluminium disc / operculum

Cardboard: This element has a double function, since it is not only necessary to incorporate and center the seal on the cap, but it will also guarantee that the seal has adequate contact with the mouth of the container once the cap is closed and before induction sealing.

Adhesive layers

Aluminium foil/lid. Without a doubt, this is the most important element of all, as without it, it would be impossible to seal the container. Nowadays, there are different types of lids, the choice of which will depend on the type of product you want to seal.
