Caps with Liners

Caps and Closures

As we deal with so many cap manufacturers we are able to source and supply you with the cap and cap lining material combination you are looking for without the need to separately supply you with cap lining material. The caps are supplied from cap manufacturers for whom we have an established trading relationship.

These cap manufacturers will almost always sell through third parties and we have qualified with many cap manufacturers to be that third party. We insure the pricing we supply is equal to or better than if you had gone to other third parties or EVEN the cap manufacturer themselves.

Our knowledge and involvement in the supply of Cap Lining Material, Lining Inserting equipment for the cap manufacturers and induction sealing equipment for the end user means we can help source “get-it right first time” combinations of caps with cap lining material and supply at very competitive pricing.

Induction Material Liner

Material Liner is what we call that piece (or pieces) of what looks like paper inside product caps. It is also referred to as induction foil, induction sealing material, foil seals and induction seals among others. Many people are unaware of the purpose they serve to the product aside from being a protection seal or a tamper proof seal.

Material Liner Purpose

Material liner within caps can be one piece or two pieces depending on the expected purpose of the lining material.

Single piece cap linersSingle piece cap liners are often present in smaller sized containers in which the product is likely to be consumed after opening. Its packaging is regarded as being one time use packaging.  In this instance, the liner functions as protection until the product is opened. No other material is left inside the cap.



Two Piece Material LinerLarger packs or bottled items are not likely to be completely consumed right after opening. The consumer is more anticipated to reclose the container and store the product. The caps used on these conditions have demands for caps that reseals effectively. Upon close examination, the caps used on these kinds of merchandise have laminated foam within. This lamination enables the cap to reseal the container upon closing to maintain product freshness.  The laminations within the cap as well as the removed tamper evident seal on the product are referred to as two-piece cap liners.

Deciding on the best components and structure of your foil seal is essential to guarantee the proper amount of protection for your merchandise. We can help you in selecting the type of material as well as the construction suitable to your application.

We have induction sealing materials available in many variants to fulfil almost any standard or individualized product packaging requirement which are safe and meet the strict specifications set by the Food and Drugs Authority.

Effective for products that must be kept free from contamination, oxidation and moisture, tamper evident hermetic seals are best suited for use in the following production:

  1. Food & Beverage
  2. Drugs
  3. Alkalies
  4. Acids
  5. Oils
  6. Organic solvents and products
  7. Flammables,
  8. Powders
  9. Pellets
  10. Other products

Induction foils are generally supplied to the closure manufacturers. Developed over 35 years ago, induction sealing, in the beginning, was designed to eliminate leakage of chemicals from plastic bottle caps. At present, this method works extremely well with most style container and closure.

Induction Sealing Process

The caps are supplied with an induction foil waiting to load into the capper. The container is then filled and capped, using the caps that are pre-lined with the induction foils.

The capped container is then transported down the conveyor line and travels underneath the induction sealing head. The electromagnetic field generated by the sealing head penetrates the cap and the aluminum foil layer. When the field permeates the foil, it causes an electrical current which melts the liner’s sealing film. The foil cools down as it leaves the induction field causing the heat seal film bond to the container. Once the cap is removed, the aluminum foil remains bonded to the lip of the container.
