Step-by-Step Guide to Matching Blister Size with Cardboard Size
When creating packaging that incorporates a blister and a backing card, it's essential to ensure that the blister size correlates accurately with the size of the backing card. Follow these steps for a proper fit:
1. Measure the Backing Card
Before you choose or create a blister pack, start by measuring the dimensions of the backing card accurately. You need to note the length and width (and height, if applicable) of the card.
2. Decide on Blister Dimensions
Based on the dimensions of the backing card, determine the size of the blister. The blister should match the size of the backing card or be a maximum of 1 mm larger in either dimension.
- Example: If your backing card measures 100mm x 150mm, your blister can be a maximum of 101mm x 151mm.
3. Check Fit and Movement
Once you have determined the blister dimensions, make sure that the backing card fits snugly inside the blister without any excess movement. The card should slide in easily, but it should not dangle inside the blister. This prevents any hazards or damage during transport.
4. Test with a Prototype
It's best practice to create a prototype by cutting out a sample of your blister and inserting your backing card. Make adjustments as necessary until you achieve the desired fit.
5. Final Adjustments
After testing the prototype, you may need to make final adjustments based on any discrepancies noticed. Remember, the main goal is to have a snug fit with minimal movement while ensuring ease of insertion and removal.
Conclusion
By following these steps, you can ensure that your blister size corresponds perfectly with your cardboard backing, maximizing the effectiveness of your packaging design.
