Expandable Envelopes

When sending via Royal Mail using Pricing in Proportion, if you can send via Large Letter rather than Small Parcel, then you can make significant savings on your postal costs, and those small savings can ultimately add up to a big difference for your business. For retailers that are selling reasonably flat items like t-shirts, costume jewelry, and even some hardware items, using a cardboard expandable envelope can make much more sense than using a larger PiP box, and offers more protection than a recycled plastic mailbag.

Having the best expandable envelopes means that those documents can all be sent together with confidence. The strength that the corrugated cardboard provides, alongside the tamper-resistant peel and seal lid flap with superior adhesive means that the chances of the envelope being damaged are greatly minimised.

Expandable envelopes are also a practical option for getting orders out quickly – and when time is of the essence, the faster your team can dispatch, the better. Unlike PiP boxes, there isn’t any assembly required with expandable envelopes, and the easy-peel & seal closure strip eliminates the need for additional products such as tape, speeding up dispatch further.

Of course, expandable envelopes are also a great option for the planet – particularly when, like order, they are made from 100% recycled Kraft paper. Cardboard is easily recycled with most household waste, and once the glue strip is removed, the envelopes are both biodegradable and compostable – meaning that should the envelope inadvertently end up in landfill, it will have a minimal environmental impact.

      What is a standard mailing bag?

      Our standard polythene bags are our best value mailing sacks, available in a large selection of sizes to suit a variety of products and purposes. The 55 micron thick grey material grants a reasonable degree of strength while remaining very lightweight to minimise postal costs. Your postage and packing outgoings can be accurately calculated thanks to the sizing table which corresponds with Royal Mail’s PiP guidelines. Intuitive practicality is embedded into the design with the 40mm lip that includes a peel-&-seal strip. This feature eliminates the need for tape, simplifying the whole packing process for increased efficiency and ease. These qualities are indispensable within a busy dispatch operation, promoting the fast functioning of an ecommerce business. Moreover, tape dispensers or cutting tools can be removed from a pack station, aiding organisation. To display delivery information, these standard mailing bags are commonly purchased with items from our comprehensive range of multi-purpose labels. Are the polythene bags eco-friendly? The grey polythene is made from recycled materials, making it a low-cost and environmentally friendly option. The extremely light weight further promotes the protection of our planet as it means that more parcels can be loaded onto a single vehicle, hence economising that space and reducing the overall carbon footprint of the process. It is worth noting that, as a result of the recycled content, the shade of grey may vary slightly from the images. Can you reuse a mailing bag? These plastic mailing bags are made with a minimum amount of recycled material to suit their single-use purpose and hence, are not designed for reuse. However, there is nothing stopping a customer from reusing a grey mailing bag if it retains its high quality condition. What are grey mailing bags used for? Thanks to the wide range of sizes supplied by Kite, the standard postal pouches can carry a broad selection of products, making them suitable for various industries. The large letter sizes are perfect for sending out clothing, literature or textiles while the larger parcels are typically used for bulky or boxed items. The opaque exterior renders the envelopes suitable for sending out confidential materials too. A polythene mailing sack is a great universal product with a variety of uses, making it an ideal versatile resource for companies sending out a range of different items. The flat-pack and ultra-thin arrival aids this end by conserving warehouse space. recycling code 4 Click here for our recycling guide
