Seal blisters and seal hoods are permanently bonded to cardboard through heat sealing — providing verifiable tamper evidence, manipulation protection and a convincing appearance at the point of sale.
A seal blister is a thermoformed plastic hood that is permanently bonded to a cardboard backing through thermal heat sealing. The seal rim between hood and cardboard cannot be opened without damage after sealing — guaranteeing full tamper evidence and visible manipulation indication.
Seal blisters are the preferred packaging format when originality sealing, tamper evidence and product protection are the highest priority. In pharmaceuticals, medical technology and premium consumer goods, the sealed blister cover has been an established standard for decades. The seal is permanent and can only be opened by damaging the cardboard — a clear identification mark for consumers and regulatory authorities.
Medicines, batteries, contact lenses, food supplements, small electronics and cosmetic products use seal blisters as their preferred packaging solution. Retailers value the clear proof of originality and completeness. In regulated markets such as pharmaceuticals, heat sealing is often mandatory.
We manufacture seal hoods from PET, PETG, PVC and PVDC coex, depending on barrier property and sealing temperature requirements. The cardboard backing is supplied with a sealable coating and sealed with the hood in our facility. Available from 5,000 units — with in-house tooling.
Heat-sealed seam guarantees tamper evidence — the seal can only be opened with visible damage.
