Blister Packaging

The blister is sealed to the blister card by heat and pressure. The card has a heat activated coating. Sealing requires a blister sealing unit.

We also provide blisters for cold seal format which is a recent trend in blister packs these days. Cold sealing is used as a tamper proof packing for specialty industries and specific products which are heat sensitive.

Cold seal blister packaging is a pressure sensitive packing using a blister card and a transparent blister. This blister is trapped in between two pieces of board which gets bonded under pressure without the use of heat. Only pressure is required to make a perfect board to board bond. We can also use materials such as Mearl, Holographic & other laminated boards for sealing solutions. Cold seal is used for packing by different industries which include : agriculture products , food & pharma packing, electronic spare parts, stationary, automotive parts, domestic appliances, batteries, promotional packs, greeting cards, to name a few. This kind of packing is being largely used in the Gold, Diamond & gems trade in a big way where the product has to be seen but also needs to be tamper proof with an certificate with specific numbers.

This is an interesting new development. The blister is placed between two pieces of cardboard sealed together. Both two single blisters and a folding blister can be used.

This form of blister pack can be reclosed after opening. The edges of the blister are folded on two, three of four sides. The blister card is inserted under the folded blister edges.

Warp-around blister are perfect for packaging fragile products. The blister has hinged parts which are wrapped around the contents. In this way the blister fully encloses the product for the best possible protection. Warp – around blisters can be closed without special equipment.

The two blister halves are joined by high- frequency welding. The resulting joint can only be broken with a knife or scissors. Hence, HF welded blister are perfect for heavy products. An HF generator is required for closing these blisters.

Thermoforming can be used to produce attractive box inserts and interiors. The insert can be tailored to the shape of the product to be packed. This ensures a perfect presentation and protection of the product. These inserts can be made from flock film for a velvet-like appearance.
