Types of polythene mailers:

Polythene mailing bags come in all shapes and sizes. They have some common features - such as their easy-to-use self-seal strip - but cater for a huge variety of postage needs with a wide range of products. Here are a few of the most popular:

Clear polythene mailers

Clear polythene mailers are lightweight and so help to reduce postage costs. They are also waterproof and tear-resistant, which makes them the ideal mailer for posting catalogues and brochures.

Blue opaque mailers

Blue opaque mailing bags are also waterproof and strong, as well as being 100% recyclable. They offer more security than a clear mailing envelope, whilst their professional appearance makes them popular with mail order or online delivery companies.

High security mailers

Tamper-evident sealing strips, thick black bags and ‘VOID’ labels to place across seals all feature in a range of high security mailing bags, which provide extra security and confidentiality for your mail.

Heavy duty mailers

Heavy duty mailing bags are made from a extra tough polythene - a strong co-extruded material that means you can post with confidence that your mail can withstand some rough handling in transit.

Superlight bubble mailers

If you need to post any valuable or delicate items, superlight bubble mailing bags can provide the all-important protection that they require. Lined with bubble wrap, these handy mailers are waterproof, strong and light.

Metallic mailers

Give your mail some extra va-va-voom with this range of premium quality metallic mailing bags. Available in a selection of glossy metallic colours, these snazzy envelopes are guaranteed to make an impact.

Coloured mailers

Another great way to get your mail noticed is to use a coloured mailing bag. Featuring colours such as baby pink, eco green, baby purple and glossy blue, this range of vivid coloured mailers will brighten up any delivery.

Biodegradable mailers

Look out for the environment while you send your mail with this range of biodegradable mailers. These strong mailing bags do the same great job as regular mailers, but they also biodegrade as compost once disposed of.

Mailing bags with handles

Mailing bags with a difference - with a seal at one end and a handle at the other, these bags are designed for easy handling.  They are also multi-use bags, as an integral double seal allows for easy returns, making them popular with online retailers.
