Bottle Cap Closure

February 1, 2023

What seal can I use to avoid leakage of my bottle?

Product manufacturers in chemicals, cosmetics, medicines, and the food and beverage industry focus more on addressing customer's evolving demands and standards. They have to ensure that their items reach their consumers in perfect condition. Shoddy merchandising, such as leaky and damaged containers, and rotten or contaminated items, are serious issues that endanger safety.

The capability to attain a flawless seal every time is now possible thanks to sophisticated production procedures. When used appropriately, the induction sealing system may enhance the value of a product. Making the container airtight creates a tamper-proof seal that solves all the aforementioned problems while maintaining an overall professional appearance. The induction cap sealing technology is also great for extending the shelf life of a product and maintaining freshness, which increases consumer confidence.

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.
