What is a sealed blister?

A sealed blister consists of a transparent blister cover and a printed blister card. After filling, the cover is machine-sealed to the card. The result is sturdy, tamper-evident retail packaging that displays the product clearly and protects it reliably.

The blister cover can be individually adapted to the product shape, security requirements and presentation goals. This makes sealed blister packaging particularly suitable for products that need to look premium at the point of sale while being packed in a theft-resistant way.

Sealed blisters as a secure packaging solution that sells

Stand out visually

Transparent blister covers make the product visible and support a strong presentation right on the shelf.

Secure with sealed blisters

The permanently sealed bond between blister cover and blister card provides a very high level of theft protection in retail.

Customised sealed blisters

Shape, contour and blister card can be tailored to your product - from the standard rectangular cover to a precisely fitting custom shape.

Design options

Printed blister cards offer space for your brand, product information and premium effects such as embossing, gloss or metallic elements.

Slide blisters: a flexible alternative

Slide blisters are a flexible alternative when no sealing process and no machine effort are wanted. A blister card is slid into a flanged plastic cover. The packaging can be closed by hand and assembled on your own premises.

Slide blisters are particularly suitable for in-house packing, small series and medium-sized series. They look premium and offer good product visibility, but are less tamper-evident than permanently sealed blisters.

Materials for sealed blisters

Blister covers are usually made of transparent PET. Depending on the requirements, A-PET or G-PET is used. The blister cards are mostly made of recycled cardboard and are coated with water-based blister varnish so that the card and cover bond securely during the sealing process.

Production and co-packing

On request, Bittner takes care of the blister cover, the blister card, filling, sealing and complete assembly as contract packing or co-packing. Your product is machine-sealed onto the card in-house and delivered as finished packaging.
