Why Proper Packaging Matters for Mondial Relay Shipments

Sending a parcel via Mondial Relay means your package will pass through automated sorting systems and be handled multiple times before reaching its destination. Good packaging protects your items, prevents delays, and ensures the parcel is accepted into the network without issue. This guide covers everything you need to know before you seal that box.

Size and Weight Limits

Mondial Relay operates within defined size and weight parameters. Parcels that exceed these limits will not be accepted into the relay network.

Parameter Standard Limit
Maximum weight 30 kg per parcel
Maximum length 150 cm on the longest side
Maximum girth Length + 2×(width + height) ≤ 300 cm
Minimum size 15 cm × 10 cm × 1 cm

Note: Always verify the latest figures on the official Mondial Relay website, as limits can be updated or vary by service type.

Choosing the Right Box or Packaging

The container you choose makes a significant difference:

  • Corrugated cardboard boxes are the gold standard. They absorb shocks and stack well in transit.
  • Padded envelopes (mailers) work well for soft, flat items like clothing or documents.
  • Plastic postal bags are suitable for non-fragile items that won't be damaged by compression.
  • Avoid reusing damaged boxes — crushed corners or weak seams can cause the parcel to open mid-transit.

How to Pack Your Items Safely

  1. Wrap fragile items individually in bubble wrap, foam sheets, or several layers of paper.
  2. Fill empty space inside the box with packing peanuts, crumpled paper, or air pillows to prevent items shifting during transit.
  3. Place the heavier items at the bottom of the box and lighter items on top.
  4. Seal every seam with strong packing tape — apply tape along all edges and the centre seam.
  5. Remove or cover any old labels from reused packaging so scanners don't misread barcodes.

Labelling Your Parcel Correctly

Your Mondial Relay shipping label is generated when you create the shipment online. Once printed:

  • Attach it flat on the largest face of the parcel.
  • Ensure the barcode is fully visible and not creased or folded.
  • Do not cover the label with tape, as this can cause reflections that confuse barcode scanners.
  • If shipping internationally, ensure the customs declaration form (CN22 or CN23) is securely attached where required.

Prohibited and Restricted Items

Mondial Relay does not accept all types of goods. Items that are generally prohibited include:

  • Dangerous goods, flammable liquids, and aerosols
  • Perishable food items
  • Live animals
  • Illegal substances
  • Cash, credit cards, and negotiable financial instruments
  • Firearms and weapons
  • Lithium batteries exceeding regulatory thresholds (when shipped alone)

For a full and up-to-date list of prohibited items, always consult Mondial Relay's official terms and conditions before shipping.

Packaging Tips for Specific Item Types

Clothing and Textiles

Use a sealed plastic bag inside the outer packaging to protect against moisture, then place in a postal bag or box.

Electronics

Wrap in anti-static bubble wrap, box individually, and surround with at least 5 cm of padding on all sides.

Books and Flat Items

Use a sturdy cardboard book mailer or wrap tightly in corrugated cardboard with rigid backing boards.

Summary

Good packaging is the single most effective way to ensure your Mondial Relay shipment arrives safely. Choose an appropriate container, pack items securely, label clearly, and always check that your parcel falls within size and weight limits. A few extra minutes spent packing well can prevent costly damage claims.
