Mailing Bags

Mailing Bags and Polythene Envelopes for Irish Businesses

Polythene mailing bags are the standard postal packaging choice for Irish businesses dispatching clothing, soft goods, catalogues, documents, and any items that require a waterproof, tear-resistant outer envelope. Unlike paper envelopes, polythene mailing bags protect contents from rain, moisture, and rough postal handling throughout delivery. HuntOffice stocks mailing bags and protective envelopes from GoSecure, HuntOffice, MailLite, White Box, 5 Star, Ampac, PostSafe, Tyvek, and Premail, in extra strong, lightweight, tamper evident, bubble lined, and padded lined formats across a wide range of sizes and pack sizes from 20 to 500. Over 43 products carry an eco-friendly designation. Fast nationwide delivery is available across all of Ireland on every order.

Extra Strong Polythene Mailing Bags

Extra strong polythene mailing bags are made from a heavier gauge polythene than standard lightweight bags - providing greater resistance to tearing, puncturing, and bursting under the weight of heavier contents. GoSecure extra strong polythene envelopes are available in white across a range of non-standard sizes from 165x240mm through to 610x700mm, in packs of 25 and 100, and are among the most popular products in this category. 5 Star Elite DX bags in white self-seal waterproof formats are available in 455x330mm and 475x440mm in packs of 100, and 5 Star Elite extra strong waterproof peel and seal opaque envelopes at 600x430mm (pack of 100) are also available for larger item dispatch. White Box and HuntOffice strong polythene mailing bags in white opaque formats from 235x320mm to 595x430mm are available in packs of 100 - a cost-effective option for high-volume e-commerce and fulfilment operations.

Lightweight Polythene Mailing Bags

Lightweight polythene mailing bags are thinner gauge than extra strong bags and are suited to lighter, less fragile items where postage weight is a consideration. GoSecure lightweight opaque polythene envelopes in white and grey are available in C4, C5, and a range of non-standard sizes in packs of 100 - the C5 white opaque lightweight (pack of 100) and the C4 lightweight (pack of 100) in both white and clear are popular choices for document and catalogue mailing. The Ampac C5 clear lightweight polythene envelope (165x230mm, pack of 100) features a clear window panel that allows the contents to show through - a professional presentation option for catalogues, brochures, and promotional materials.

Grey Polythene Mailing Bags

Grey polythene mailing bags are the standard finish for e-commerce and online retail dispatch across Ireland and the UK - the opaque grey colour conceals the contents, and the neutral tone is widely associated with consumer parcel delivery. HuntOffice and PostSafe grey polythene mailing bags are available in sizes from 170x230mm through to 715x585mm in packs of 100, 250, and 500, making them well suited to medium and high-volume e-commerce operations. Grey polythene mailing bags with a 50mm flap are available in sizes from 170x230mm to 600x900mm in packs of 100 and 500 - the longer flap provides extra security and a neater seal on softer, bulkier items such as clothing and textiles.

Tamper Evident Mailing Bags

Tamper evident mailing bags display a visible warning message if the seal has been broken after dispatch - making them the correct choice for sending confidential documents, sensitive data, cash, payroll details, legal papers, and high-value items where evidence of tampering in transit is important. Ampac tamper evident protective envelopes are available in C5+ white opaque (pack of 20), C3+ opaque (pack of 20), and 220x305mm white opaque (pack of 20) formats with a double peel and seal closure. These are widely used by Irish legal firms, financial services organisations, healthcare providers, and public bodies sending sensitive documents by post or internal courier.

Tyvek Envelopes

Tyvek envelopes are made from a synthetic material - not paper, not polythene - that is tear-resistant, waterproof, and significantly lighter than paper envelopes of equivalent strength. The Tyvek C5 pocket envelope (229x162mm, 100gsm, peel and seal, white, pack of 100) is the only Tyvek format stocked in this range and is the specialist choice for Irish organisations sending documents that require a combination of light weight, high durability, and moisture resistance - commonly used in engineering, construction, and healthcare for sending plans, forms, and records that must survive outdoor handling or long transit times.

Bubble Lined and Padded Mailing Bags

Bubble lined and padded mailing bags combine the waterproof, tear-resistant outer shell of a polythene mailing bag with internal cushioning - making them suited to fragile, delicate, or irregularly shaped items that require impact protection as well as waterproofing. MailLite Plus oyster white bubble lined postal bags are available in sizes C/0 (150x210mm) through to K/7 (350x470mm) in packs of 50 and 100 and are one of the top-selling formats in this category for Irish e-commerce sellers dispatching small products. For a broader range of bubble lined and padded envelope options, including the full Jiffy bag range, see the Jiffy Bags and Padded Envelopes category.

•There are two maind types of Jiffy Bags - Bubble Lined and Padded Lined

 

We have a choice of protective envelope seal types which include: 

• Peel & seal – This is the most common way of sealing envelopes. The flap of the envelope has a strip of glue which is protected with a strip of plastic. Remove the plastic strip from the flap and press against the envelope to seal. Peel & seal envelopes are ideal if you like to buy in bulk because with the plastic strip protecting the glue, even after months of being kept in storage, the glue won’t dry out. 
• Zip closure is the most secure way of sealing protective envelopes. It provides not only tamper proof protection for important documents but also keeps an air tight seal against moisture and dust. 
• On self-seal protective envelopes both the envelope and the flap have strips of adhesive. These are pressed together to form a strong bond.

Frequently Asked Questions

1 - What types of protective envelopes does HuntOffice carry?

HuntOffice carries a wide range of protective envelopes including padded bubble envelopes, board-backed envelopes for protecting flat items such as photographs and documents, jiffy bags, and poly mailing bags. These are suited to e-commerce despatch, internal post, and any situation where items need protection during transit. Our customer service team can help identify the most appropriate type and size for your specific items and despatch volumes.

2 - What is the difference between a bubble envelope and a board-backed envelope?

A bubble envelope - also called a jiffy bag or padded mailer - has an inner lining of bubble wrap that provides cushioning to protect fragile or delicate items during postal transit. A board-backed envelope contains a rigid card insert that prevents the contents from bending or creasing during handling - these are used for photographs, certificates, artwork, and flat items that must arrive undamaged. HuntOffice carries both types in a range of sizes. Our customer service team can advise on the most suitable option for your items.

3 - What sizes of protective envelopes are available?

Protective envelopes are available from HuntOffice in a range of standard sizes to accommodate different item dimensions. Padded bubble envelopes are available in sizes from small (suited to jewellery, USB drives, and small accessories) up to large formats for books, tablets, and A4 documents. Board-backed envelopes are typically available in A5, A4, and A3 sizes. Our customer service team can advise on the right size for the items you are sending.

4 - Are your protective envelopes suitable for Royal Mail and An Post postal services?

Protective envelopes available from HuntOffice are suitable for use with An Post postal services and standard courier services operating in Ireland. Ensuring the envelope dimensions and weight fall within your carrier's size and weight limits for the relevant service level is the sender's responsibility. Our customer service team can advise on the dimensions of specific envelope sizes to help you confirm postal eligibility.
