Vacuum, blister and skin-pack packaging dies
Vacuum cutting dies:
blister and PVC card form
In vacuum and blister packaging a die does more than cut the outline; the card's blister seating area, the hang hole, the double-blister edge and how the PVC/PET separates without cracking decide the result. The rule plan is built around that behavior.
Where this die fits
Vacuum cutting dies are used for blister cards, skin-pack packaging, vacuum tray flanges and hang-hole cards. On thin transparent materials such as PVC and PET, the hang-hole center and corner radius directly affect how cleanly the part releases.
The outer card shape, the blister seating area, the hang hole and the double-blister edge are planned in one file; dimensions are confirmed together from a sample or a technical drawing.
- Blister card and double-blister edge
- Skin-pack and hang-hole cards
- Vacuum tray flange cutting
- PVC, PET transparent form
What we check before production
On a blister job a few tenths of a millimetre of drift can keep the blister lid from seating on the card. So the seating line, the hang hole and the corner form are read together.
- Blister seating line and card size
- Euro (hang) hole center and form
- Corner radius and edge cleanliness
- PVC/PET thickness, cracking and kiss-cut allowance
Quote information
Material type and thickness are the main quote inputs. If no technical drawing exists, a good blister-card sample can be redrawn.
- Technical drawing or measured sample
- Material type and thickness
- Blister/card size and hang-hole type
- Quantity, sheet size and deadline
Common questions
1What is the difference between a vacuum die and an RF die?
An RF (radio-frequency) die welds and forms with high frequency, while a vacuum-blister cutting die cuts the card and the blister edge. The two are used together on most blister jobs and can be planned from the same file.
2Can a euro (hang) hole be cut into the die?
Yes. The euro/hang hole, the blister seating area and the outer card shape are drawn in one die; the hole center and corner radius are checked before production.
3Can PVC and PET be cut without cracking?
Material thickness, corner radius and rule form are tuned together. On thin transparent material the right radius and base are chosen to reduce the risk of cracking.
