How to Choose the Right Blister Packaging Thickness – Let’s Get Technical
Hey there, this is River👋 from Plarmor, and after 10+ years of wrestling with blister packs (the good kind of wrestling), I'm here to spill the secrets on picking the perfect thickness--not perfect actually but roundly correct :).
Tiny & Mighty? Keep It Thin (0.25mm–0.35mm)
Got erasers, pens, or batteries? For carded blisters (the ones with a snazzy paper back), 0.25mm–0.35mm is your golden zone. Why? These little guys don't need much muscle, and too much plastic = awkward stretching during thermoforming. Nobody wants a lopsided blister.
Bigger Stuff? Beef It Up (0.5mm)
Now, imagine packing two baseballs. A flimsy 0.35mm blister might go "pop!" mid-mold. 0.5mm saves the day—it stretches just enough to hug those curves without tearing. Trust me, I've seen the "Oops, my blister exploded" face. Not cute.
Heavy-Duty Heroes? Clamshell to the Rescue (0.5mm–0.6mm x 2)
Enter the clamshell blister—the MVP for chunky items. Two 0.5mm–0.6mm shells snap together like a stylish plastic taco, and guess what? Many even fold into a stand (no pegs needed). Retailers love this trick.
