Sealing a candwich (canned sandwich) cardboard box properly ensures freshness, hygiene, and secure transportation. Here’s a step-by-step guide:
Depending on the type of cardboard box, you can seal it using one of the following methods:
✅ Self-locking tabs – Some sandwich boxes come with built-in folding tabs that lock into place.
✅ Adhesive stickers or labels – Great for branding and ensuring the box stays closed.
✅ Tamper-evident seals/Heat Sealing – Ideal for commercial packaging to show the box hasn’t been opened.
✅ Glue or double-sided tape – Provides extra security for bulk transport.
Step 1: Fold the Flaps Properly
Ensure the sandwich and any packaging (wax paper, foil, or plastic wrap) are neatly inside.
Fold down the top flap first, then tuck in the side flaps securely.
Step 2: Use a Sticker or Label (for takeaway or retail packaging)
Place a branded label or tamper-proof sticker over the box closure.
This adds security and makes it easy for customers to identify the product.
Step 3: Apply a Tamper-Evident Seal (for commercial products)
Use a pre-cut security seal to ensure the box hasn’t been opened before purchase.
This is useful for delivery, retail, and food service industries.
Step 4: Use Heat Sealing (If Required)
Some packaging lines heat-seal plastic film around the box to maintain hygiene.
This method is common in factory production and large-scale food packaging.
Step 5: Stack and Store Properly
Once sealed, stack the boxes carefully to avoid crushing.
Keep in a cool, dry place to maintain freshness.
✔ Use food-grade adhesive labels if sealing with stickers.
✔ Ensure ventilation if packaging warm sandwiches to prevent condensation.
✔ For bulk shipments, consider shrink-wrapping multiple boxes together.
