What to look for in an Induction Seal:

• After starting the induction sealing process, a satisfactory seal is achieved. For best results, manufacturers strongly advise waiting at least 24 hours for the optimum result.
• Heat Excess: Watch out for any symptoms of burning or melting within the cap.
• Underrated If the foil sealing coat did not melt and connect with the whole rim of the bottle or jar top neck surface.
• Proper heating: It is determined by whether the foil seals around the rim of the product and secondary cap lining materials, as well as if the bottleneck and cap are not overheated.
• A proficient operator will understand how hot a bottle lid should be before it begins to cool.
• A trained operator may see symmetric heat patterns in induction foil and foam backing material beneath some induction foils.

Proper Induction Sealing is attained if:

• Without the cap, the seal can naturally withstand and protect the content inside the container.
• The seal on easy-peel seals can be removed without leaving any trace of foil ring behind.
• No leaks were detected after being dropped.

How to achieve a perfect induction Seal?

The container, cap closure, liner material, and induction seal should all be perfectly matched to attain a consistent product seal. It will be better to check your cap closure with the Induction Cap Sealing Machine supplier to discover the best combination.

Container

Most induction-sealed containers are made of PET & HDPE, while glass Jars can also be induction sealed. The container type is preferred depending on product suitability, marketing, and logistical concerns.

Cap Closure

The cap closure must have a flat interior part to accommodate an induction liner. Screw-on caps provide a more comprehensive selection of hard and soft cap liner materials. Snap-on caps are better for more delicate cap lining materials.

Lining Materials

The following aspects influence the selection of an acceptable induction seal material:

• The container design
• Content of product
• Duration of use
• Any Cap Tolerance (e.g., Screw-on or Snap-on caps)
• Process for inserting the lining material into the cap

Induction Sealer

Selecting the best machine for your needs is a crucial process. When choosing a provider, consider the following points:
The provider can offer technical guidance on the induction sealing method and, if required, engage in the closure and container development procedure

• The provider provides only certified equipment since high electric currents, and electromagnetic fields are used in induction sealing equipment.
