Size 4 Bubble Lined Bags™ measure 225 x 330mm internally and 250 x 350mm externally making them perfect for sending A4 size items. We use a high slip coating on the bubble wrap inside the bags so packing is easy and hassle-free, and the peel and seal closure ensures your items are secure in transit. The edges of the bag are heat welded for enhanced burst resistance and the strong 92gsm white laminated paper outer gives a professional finish. Made climate neutrally and from sustainably sourced materials, these bubble lined bags can also be recycled. Simply separate the paper from the inner bubble material by tearing along the edge, and then either reuse the bubble bag, or recycle both paper and bubble interior in their correct waste streams.  Our white Size 4 Bubble Lined Bags™ are a low-cost alternative to Size 4 Jiffy Bags, G-4 Mail Lite Envelopes, Featherpost Size G and Arofol Size 7 bags.   Please note: Print colour and design on bags may vary, and due to manufacturing tolerances, bag dimensions may vary slightly.
