How to Seal a Candwich (Canned Sandwich) Cardboard Box

Sealing a candwich (canned sandwich) cardboard box properly ensures freshness, hygiene, and secure transportation. Here’s a step-by-step guide:

1. Choose the Right Sealing Method

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.

2. Steps to Seal a Candwich Cardboard Box

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.

Additional Tips

✔ 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.
