Our Size 7 Bubble Lined Bags™ are the largest size in our White range and are perfect when sending A3 products. Measuring 350 x 470mm internally and 370 x 480mm externally, these A3 size Bubble Lined Bags™ are made with a strong and presentable 92gsm white laminated paper outer and have heat welded edges for all round protection and burst resistance. The bubble wrap interior has a high-slip coating for easy packing and a peel and seal closure makes for speedy despatch. Boasting eco credentials such as, carbon neutral, sustainably sourced and FSC approved, our bubble lined bags are also recyclable. To recycle responsibly, please separate the paper outer from the bubble interior and dispose of them in 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.   Please note: Print colour and design on bags may vary, and due to manufacturing tolerances, bag dimensions may vary slightly.
