On some campaigns we may send out small plastic boxes A6 in size when the cards need extra protection during transit. For example if we are doing a note only campaign where the cards won't have envelopes.
The plastic tubs have the bottom base and the lid which covers over the box, this allows you to put your cards inside the box (the amount that fit in the box will vary depending on card thickness and if they have envelopes, on larger jobs we will include more boxes if needed). The box can then be secured with an elastic band once closed and sent to our print warehouse in the original box it arrived to you in or we will include a postal bag for it to go into. This may include some bubble wrap for extra protection in transit.
When sealing the jiffy bag, please ensure the box is securely inside, you may need to add some sellotape if the jiffy bag is larger and you are only sending on box to help compress the envelope and wrap it around the box.
We usually also include a small sticky label for you to write your job number and name on and add to the outside of your parcel (not the plastic box as we reuse those to send out on other jobs). If this is missing, it's very helpful to add your job number to the envelope in pen so that the warehouse team can easily identity which job or campaign it is for.
