Induction cap sealing machine best suitable for Bottle, Jar and Jerry cans

Induction cap sealing machine 

Over the years, induction sealing has been of great importance to the packaging industry where containers need to be ensured of being leak-proof. Every other product packed in plastic containers such as pharmaceuticals, food, agrochemicals, lubricants, etc. Are now being induction sealed. It is a fast and easy way to ensure that your product is safe from contamination and duplication. Earlier conventional bore seals were used to seal containers but the doubt remains whether this kind of seal protects the product that we use.

Cases of spillage and contamination of the product led to finding an alternative and hence the induction seal concept popularized. Being a fast and secure method of heat sealing an aluminium foil laminated with a compatible polymer, this concept is ever growing in the packaging market as an advanced and safe sealing method.

Automatic induction cap sealing machine creates a hermetic seal useful in preventing leaks, preserving freshness and preserving the shelf life of products very effectively. The induction cap sealer is efficient with enhanced sealing capacity that has minimal waste and maintains the aesthetic appeal of the package. The calibration and set up of the machine is easy and user friendly thus enabling management of different types and sizes of labels repeatedly.  It is also equipped with internal counters and process monitoring that detects errors and faults and stops early enough to prevent further damage from happening.

Induction cap sealing basics process

  • Induction sealing is a non-contact heating process that welds a foil laminate (called an inner-seal) to the lip of jars and bottles. The sealing process takes place after the filling and capping operation. Capped containers pass under an induction cap sealer mounted over a conveyor. The fad recognizes induction sealing as an effective means of tamper evidence.
  • The standard system has two main components, the power supply, and the sealing head. The power supply is an electrical generator operating at medium to high frequencies. The sealing head is a plastic case that houses a conductor formed into an (inductive) coil.
  • When energized by the power supply, the head produces an electromagnetic current, called an eddy current. When capped the bottles enter this electromagnetic current, the foil of the inner-seal generates electrical resistance, heating the foil.
  • The hot foil in turn melts the polymer coating on the inner-seal. The heat, coupled with the pressure of the cap, causes the inner-seal to bond to the lip of the container. The result is a hermetic seal.
  • The strength of the power supply depends on the size of the closure and the speed of the production line, while the design of the sealing head depends on the application. The two most common shapes are the flat head and tunnel head.
  • The inner-seal you choose also depends on the application, and there are several combinations of inner-seal materials, including foam-backed and paper-backed foil laminates.
  • When necessary, the inner-seals are very tenacious, forcing you to destroy them to reach the container’s contents. In other cases the seals are easily peeled.
  • Plastic containers with screw-on plastic caps are easiest to seal. Other applications may take a little more work. It is also possible to seal glass containers and to seal with metal caps, but both applications pose challenges. Glass containers may need to be treated before the lip of the container will accept a seal. And while it’s technically feasible, induction sealing with a metal cap requires further consideration.
  • The sealing equipment will heat both the inner-seal foil and the metal cap, and the metal cap will stay hot for a while – presenting a possible safety problem. Hot metal caps could also melt the plastic threads of a container.

Induction cap sealer  available in different models – 1000 model, 2000 model, 3000 model, and 4000 model are although there are a wide range of closures available, the conventional bore sealing has, to date, been the most widely used method of sealing containers .bore seals are inexpensive to manufacture and are relatively easy to fit. However, bore seals do not form hermetic, flexible or even reliable seals- they leak. There are three types of closures available, which are either inserted into the neck of or form a combination of two. The effectiveness of this seal can be affected by temperature, natural relaxation & mechanical properties, all of which will cause the seal to leak, especially in transit.

Using the induction cap sealing technology, it’s now possible to create an alternative, alright, hermetic seals on the necks of containers. The process can produce significant cost savings. The seal is strong, flexible & yet easy to remove, and protects against cross contamination and an effective tamper-evident layer.

Advantages of induction cap sealing machine

  • Tamper proof: it is not possible, from production to the consumer that the content of the product is manipulated without being noticed.
  • Product freshness: the taste and aroma of the product remain intact due to the hermetic seal.
  • Protection against leakage: there is no spillage or loss of contents of the product.
  • Sales promotion: the foil on the inside can be used for advertising or promotional purposes.
  • Maximum filling speeds: the sealing takes place without any direct contact which allows the full potential of the filling plant to be utilized. Minimum effort: the wad is put in the cap by the manufacturers. Thus the filling line requires only the induction cap sealing equipment to be installed.
  • Indirect heating: induction heating allows heat sensitive products such as creams, petroleum product, pesticides etc. To be sealed faster and safer than direct heating which would normally spoil or catch fire.
  • Igbt technology: igbt’s are more reliable and efficient at higher line speeds.

The process of induction cap sealing is based on the principle that a conductive material i.e. Al foil heats up on exposure to high frequency magnetic field generated by an induction unit. This is a non-contact process without direct heat transfer. Due to this, the sealable closure liner can be placed in the cap by the manufacturer. The wad consists of a board packing material, a wax layer, aluminium foil and a sealable film. The screw cap combination passes through the induction unit after the closure of the container. When the container is under the induction head, heat is developed into the aluminium layer.

The wax layer starts to melt and penetrates the board layer. The sealing layer also melts & forms a tight seal against the lip of the container. The necessary pressure is provided by the liner/screw cap combination. On opening the container, the board remains inside the cap and serves as a seal on further use, whereas the aluminium foil is permanently sealed on the rim of the mouth of the container.
