Can i put something thick in a flat plastic mailer

The eternal question!

In general, it's not recommended to put thick or heavy items in flat plastic mailers, as they may not provide sufficient protection or support for the item. Here's why:

  1. Bulge risk: If the item is too thick or heavy, it may cause the plastic mailer to bulge or even tear, which can lead to damage to the item or the mailer itself.
  2. Insufficient protection: Flat plastic mailers are designed to protect lightweight items, such as papers, documents, or small packages. They may not provide adequate protection for thicker or heavier items, which could be damaged during transit.
  3. Difficulty in sealing: If the item is too thick or heavy, it may be challenging to seal the plastic mailer properly, which can compromise the integrity of the package.

That being said, if you still want to use a flat plastic mailer for a thicker or heavier item, here are some tips to consider:

  1. Choose a thicker mailer: Look for flat plastic mailers specifically designed for heavier or thicker items. These mailers are usually made of thicker plastic and may have additional reinforcement, such as corrugated cardboard inserts.
  2. Use additional support: Consider adding extra support, such as bubble wrap, foam inserts, or cardboard inserts, to help keep the item stable and prevent damage during transit.
  3. Check the weight limit: Make sure to check the weight limit of the mailer, as specified by the manufacturer. If the item exceeds the weight limit, you may need to use a different type of packaging material.
  4. Consider alternative packaging: If the item is too thick or heavy for a flat plastic mailer, consider using a different type of packaging material, such as a box, envelope, or specialty packaging solution.

Remember, it's always better to err on the side of caution when shipping items. If you're unsure about the suitability of a flat plastic mailer for your item, consult with a packaging expert or the shipping carrier for guidance.
