A header card is a small structure as well as a branding panel. Once folded around a bag, it has a front, a back, a crease and an attachment zone. Designing it as one uninterrupted rectangle can leave a logo upside down or put supporting copy under a staple. Start with a filled bag and the card supplier’s construction drawing, then assign each visible panel a clear job.
01
Distinguish a fold-over card from an insertable header
A conventional bag topper folds over the bag opening. Header Card Packaging describes a scored cardstock construction attached with staples, while also offering other production options. An insertable-header bag has a dedicated place for a separate card; ClearBags lists that format independently. Their artwork sizes and assembly routes should not be treated as interchangeable.
Ask for a bag model, card drawing and proposed attachment method on the same quote. Use the supplier’s specifications for the actual contents. A printed card is not proof that the bag is appropriate for food contact, product weight or storage conditions. Those decisions belong to the complete packaging specification.
02
Draw the flat card and the finished panels
Mark the fold across a paper rectangle and label its two sides FRONT and BACK before adding graphics. Fold it around an empty bag, then around a representative filled one. Check which panel faces the buyer and how the back is oriented after the fold rather than relying on your screen’s top and bottom.
For an illustrative 100 mm-wide bag, a proposed 100 mm-wide card folded to a 35 mm visible height would begin as a 100 by 70 mm flat concept before supplier allowances. Those are example planning dimensions, not a production template. The printer must confirm the crease, finished size and any hole, bleed or attachment requirements.
| Feature | Layout role |
|---|---|
| Front face | Product identity and variant |
| Back face | Approved supporting wording |
| Fold and fastening | Keep essential text clear |
| Hang opening, if present | Use supplier-defined exclusion |
03
Proof the card with the filled bag
Fill a sample to its intended presentation and position the card using the approved attachment approach. Look at how the bag gathers beneath it. A card that seems neat on an empty flat bag can sit unevenly when a bulky product pushes outward or the product settles below the header.
If the pack will hang, ask the converter to approve its attachment and load-bearing construction. Then inspect the displayed sample from the shopper’s normal viewing direction. Record any twist, covered wording or contact with neighboring packs. Do not infer safe hanging performance simply because the hole and card look substantial.
04
Keep artwork and assembly instructions paired
Name the approved files with the bag model and card version, not only the product name. Include a photograph showing which side faces forward and where the approved fastening lands. This gives a packer a clear reference when two similar cards have different supporting information or variant names.
Use coordinated editable artwork to carry a recognizable brand from the label to the header, while checking which formats your chosen template actually provides. Physical cards, bag stock, creasing and fastening are separate production decisions. Reproof the assembled pack when changing any of those components rather than stretching the old art to a newly guessed size.
BEFORE YOUR NEXT STEP
Your practical checklist
- Identify fold-over versus insertable construction.
- Confirm flat size and folded orientation.
- Reserve fold, hole and attachment space.
- Approve the filled pack and assembly reference.
Questions & answers
Can I design both header panels the same way up?+
Follow the supplier’s fold map. Mark a paper dummy and fold it around the bag to establish the correct orientation before preparing the final artwork.
Can the card alone make any bag suitable for hanging?+
No. The bag, attachment, card and product load work together. Ask the packaging supplier to approve that construction for the intended use.
