What Is a Trapped Blister?

With a trapped blister, a thermoformed plastic hood is slid over a cardboard backing and secured by lateral cuts or edge folds — hence the name. This clamping connection holds the product securely without adhesive or heat sealing. At the same time, the cardboard backing enables high-quality full-surface printing.

The trapped blister combines two worlds: the transparent plastic hood presents the product optimally, while the cardboard backing serves as a full-surface advertising space. Brand logos, product descriptions, barcodes, security features and regulatory information all fit on the reverse. The combination of plastic and cardboard also reduces material usage compared to all-plastic solutions.

Trapped blisters are widely used in chemists, supermarkets, DIY stores and specialist shops: razors, stationery, small tools, household goods, garden articles and toy accessories are frequently presented in this packaging format. The solution is ideal for products where marketing and visibility are equally important.

We manufacture the blister cover from PET, PETG or PVC — depending on the desired rigidity. The cardboard is matched to your print specifications. Cut-outs, perforations and Euro slots for hanging are milled to your requirements. Available from 5,000 units.
