Sealing and Labelling your Shipping Box

Packing away your contents in a shipping box is important but making you seal and label them correctly, is also vital. In this blog, we look at sealing and labelling your shipping box in order for it to retain its shape and protect the contents within during its journey. It is important to choose the right sealing type and how you seal the shipping box too is as important.

The tape you choose and the way you seal your shipping box makes a great difference in the way your shipping box behaves whilst in transit. We recommend the use of pressure sensitive tape, as they are known for its strength and durability. The types of adhesive tapes that you should use when sealing your shipping box would be the following.

Brown Plastic (Polypropylene) Tape

Electrical (Vinyl adhesive) Tape

Duct (Fiber-reinforced paper) Tape


You should avoid using tapes such as kraft paper tapes, cellophane tapes, masking tapes and string/ropes. Once you have the tape sorted, you need to ensure that you tape it the right way. The way you go about sealing your shipping box will also ensure the intergrity of the box and protect the contents within. Transco Cargo recommends the use of the H-taping sealing method for your shipping boxes so that all seams are closed up and the edges are also protected as depicted below


Instructions for H-Tape Sealing your Shipping Box

  1. Place one strip of tape along the centre seam of the shipping box
  2. Place two strips of tape across both of the edge seams
  3. If you are including heavier contents, apply more tape over the H-taping
  4. Repeat the same for the bottom, to ensure a proper seal all around

We do not recommend the use of strapping as it will damage the shipping box for those that are less than 30kg.


When it comes to labelling your shipping box, especially if you require the shipping box to maintain a certain orientation during transit, or if they are fragile, ensuring that you have the right shipping labels will allow shipping handlers to make conscious efforts to handle them based on your requirements.
