*Please note, due to manufacturing changes, these bags are now made from 100% recycled paper, and the inner bubble material is made from between 30-50% recycled content - the outer colour may appear darker, and the inner lining is now white* Our Size 7 Bubble Lined Bags™ are the perfect choice when sending A3 sized products. Measuring 350 x 470mm internally and 370 x 480mm externally, these A3 size padded envelopes are made from 92gsm laminated paper in a traditional gold colour and have heat welded edges for all round protection with enhanced burst resistance. The bubble wrap interior has a high-slip coating for snag-free, easy packing and a peel and seal closure makes your packing process quick and hassle-free. Manufactured carbon neutrally, and made from sustainably sourced materials, these eco-friendly bubble lined bags are also recyclable. Simply separate the paper outer from the bubble interior, and then either reuse the bubble bag or recycle the components responsibly, ensuring they are disposed of through the correct waste stream. Our Size 7 Bubble Lined Bags™ are a great value alternative to Featherpost Size K bags, Size 7 Jiffy Bags, K-7 Mail Lite Envelopes and Arofol Size 10 envelopes.
