*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* Gold Size 4 Bubble Lined Bags™ are the perfect choice for sending A4 sized items. Measuring 225 x 330mm internally and 250 x 350mm externally, these A4 bubble lined bags are made from 92gsm paper and have heat welded edges for enhanced burst protection. The quality bubble wrap interior has a high-slip coating to allow for snag-free packing and a peel and seal closure makes your packing process fast and easy. As well as being an efficient, cost-effective packing solution, our standard bubble lined bags are eco-friendly too. Made from sustainably sourced materials and manufactured climate neutral, these bubble lined bags are recyclable as well. Simply tear the paper from the opening edge to separate from the bubble interior, then either re-use the bubble bag, or recycle the paper and the bubble material in the correct waste streams. Our Size 4 Bubble Lined Bags™ are a great value alternative to Featherpost Size G bags, Size 4 Jiffy Bags, G-4 Mail Lite Envelopes and Arofol Size 7 envelopes.
