small ‘A1’ size Amazon style rigid cardboard envelopes. These are equivalent to size ‘D/JL1’ in the bubble envelope range. The size of each envelope is 235mm x 180mm – they are 100% rigid and recyclable with peel & seel strips for easy application, and are 400gsm in thickness. These capacity envelopes are made from fluted corrugated board, and have up to 40mm capacity / depth when expanded at the bottom (meaning that both flat items or items up to 40mm deep can be sent in these capacity mailers). They also contain an easy-open tear strip for your customer, to be used once they receive the item. Perfect for sending CD’s and alike in the post.

The A1 kraft envelope is proven to be the most operationally cost-effective method of mailing a DVD through the Royal Mail Large Letter Size Tariff. Further benefits as below:

• Proven to be up to 60% faster to pack (60% faster than a book wrap and 15% faster than a bubble envelopes):
• Reduces returns significantly – research conducted suggests these reduce return rates by 63% on average for on-line CD sellers
• Minimised Postage Cost: 18-23mm thick DVD boxes sets & books packaged in a standard 8mm thick bubble envelope would be too thick for the 25mm restriction of royal mail ‘large letter’ and would cost twice as much to mail as a ‘packet’ rate. A cardboard rigid envelope is just 1.6mm thick.
