Blank Kraft Boxes Sized for 5ml, 6ml, 7ml, and 9ml Glass Jars

A blank box transforms loose jars into finished retail products. These flat-pack boxes fold easily and provide both protection during shipment and professional presentation at the moment of unboxing.

What's Included

• Flat-pack kraft or white boxes (quantity varies by variant)
• Pre-cut and scored for easy folding
• No assembly glue required (slot-lock design)
• Ready for immediate printing or decoration

Key Features

• Custom-printable surface: Blank white or kraft exterior accepts digital printing, screen printing, offset printing, or hand-applied labels without any pre-design barriers.
• Right-size fit: Each variant is sized to snugly hold the corresponding jar diameter. Not oversized, not cramped. Contents stay centered and protected during handling.
• Sturdy cardboard: Kraft or white chipboard construction protects jars from impact, moisture, and light exposure during storage and shipment.
• Flat-pack efficiency: Arrives flat, folds quickly without tools. Saves warehouse space and shipping cost until assembly.
• Slot-lock design: No glue, tabs, or adhesive required. Fold the side flaps and insert them into reinforced slots on the bottom and top panels.
• Unbranded canvas: Your design philosophy here. Add your logo, tagline, QR code, batch number, or promotional message without reprinting costs or minimum order hassles.

Applications

• Retail branding: Small-batch producers and e-commerce sellers who want professional unboxing moments without expensive custom print orders.
• Sample curation: Gift sets, discovery boxes, or selected collections benefit from protective presentation packaging that feels intentional.
• Bulk and B2B: Resellers and distributors appreciate durable kraft boxes that ship safely and arrive ready for shelving or resale.
• Custom printing workshops: Brands that do in-house screen printing, vinyl decal application, or hand-illustrated designs start with blank boxes for maximum creative control.
• Subscription boxes: Monthly or seasonal subscriptions gain brand presence and unboxing appeal with custom-printed blank boxes.
• Promotional packaging: Special edition runs, holiday collections, or limited releases benefit from rapid turnaround, blank boxes arrive fast and can be customized immediately.
• Event or pop-up merchandise: Pop-up shops, farmers markets, and trade shows need packaging fast. Blank boxes printed on-demand via local providers keep costs low and turnaround short.

How to Use (Step-by-Step)

1. Remove one flat-pack box from the packaging and lay it flat on a clean surface, printed side (if applicable) facing up.
2. Fold up the four side walls along the scored creases. They should stand upright naturally.
3. Insert the bottom flaps into the reinforced slot at the base of the box. They lock in place without adhesive.
4. Place the jar inside the box, ensuring it sits centered and doesn't tip toward any wall.
5. Fold the top flaps and insert them into the slot on the inside of the top panel to close the box securely.
6. Seal the top with packing tape, sticker seals, or heat-shrink wrap if additional security is needed for shipment.
7. Label the outside with addressing, barcodes, or promotional stickers if required.
8. Ship or display. Unopened, the box protects the jar from light, dust, and minor impacts.

Compared to Alternatives

Pre-printed boxes force you to commit to a design and pay for large minimum orders (often 500+ units). Plastic clamshells are transparent and offer no privacy or brand messaging. Tissue paper or bubble mailers are cheap but feel temporary, they don't convey care or quality. Blank boxes give you the speed of ready-made construction with the flexibility of unlimited custom design, all without bulk printing costs or lead times.

Frequently Asked Questions

Do I need glue or tape to assemble these boxes?

No. The slot-lock design means you fold the flaps into reinforced slots on the box panels. They lock without adhesive. Packing tape for final sealing during shipment is optional.

What printing method works best on these blank boxes?

All methods work: digital printing (from local print shops). Screen printing (for bold graphics), offset printing (for high-volume runs), or hand-applied labels and decals. Test a sample with your chosen method first if in doubt.

Can I print on kraft boxes the same way as white boxes?

Yes, both accept printing. Kraft is more absorbent, so inks may spread slightly more. White offers sharper detail and brighter colors. Consider a test batch if color-critical work is involved.

How much does it cost to print these boxes?

Printing costs depend on your method. Digital printing (local print shops) runs $0.10, $0.50 per box for single-color or full-color small runs. Screen printing is cheaper per unit ($0.05, $0.20) but requires setup fees ($50, $150). Offset printing is most economical at scale (500+ units). We'd recommend getting quotes from 2, 3 local print partners.

Are these boxes food-safe for direct food contact?

Kraft and white boxes meet general food-contact standards. Most jurisdictions when used as secondary packaging (packaging around a jar, not in direct contact with food). Confirm local regulations if direct food contact is needed.

Can I reuse or recycle these boxes?

Absolutely. They're 100% recyclable cardboard. Many customers reuse them for storage, gifts, or mailing. End users typically recycle them after unboxing.

Care & Storage

Store flat-pack boxes in a cool, dry place away from high humidity, which can soften cardboard and weaken the slot-lock mechanism. Humidity above 65% isn't ideal. If you're storing printed boxes, avoid direct sunlight to prevent ink fading. Assembled empty boxes can be stacked, but avoid stacking more than 20 units high to prevent compression. Before use, inspect the slot-lock areas for any damage from shipping or handling.
