Jiffy bubble mailers – options at a glance

Jiffy Airkraft (Gold & White)

Lightweight paper-faced mailers with internal bubble lining for impact absorption. The gold kraft exterior hides scuffs; white provides a crisp, branded look.

  • Ideal for: small electronics, components, cosmetics, accessories.
  • Benefits: low weight, good cushioning, neat presentation.
  • Tip: pair with address labels for fast bench processing.

Jiffy Ocean Green & Padded Bags

Ocean Green utilises recycled content for a lower-impact alternative. Traditional Jiffy padded bags use macerated paper padding for robust cushioning and durability.

  • Ideal for: books, spares, boxed items that need extra crush resistance.
  • Benefits: proven protection, eco-forward options, wide size range.
  • Tip: add documents enclosed for customs/invoices.

Workflow & presentation

Standardise a small family of sizes, stage them at the bench, and pre-apply labels where possible. Use tape or built-in peel-and-seal. Include documents enclosed wallets for invoices/returns and encourage reuse by advising customers to open with the tear strip.

Complete your mailing setup

For fragile kits add tissue or paper bubble wrap. For catalogues and flats see cardboard envelopes. For larger consignments move to cardboard boxes or postal tubes.

Mailing Bags – Frequently Asked Questions

Bubble mailers provide the highest protection in the mailing bag family thanks to their cushioned liners. For very delicate goods, wrap items in extra bubble or honeycomb wrap inside the mailer.

Choose plastic mailing bags for wet-weather routes, returns logistics or heavier soft goods. Paper mailers suit brand presentation and simple kerbside recycling in dry chains.

Jiffy Hexpand expands to fit product height, cutting void, padding and DIM charges while maintaining a neat, fully paper exterior.

Ranges differ. Paper-faced bubble mailers combine paper and PE bubble; check local recycling guidance. Consider paper mailers or Ocean Green options if you prefer higher recycled content.

Right-size the mailer, minimise void with expandable Hexpand, and swap boxes for mailers when protection needs allow. Keep labels flat and avoid unnecessary inserts.

For online retailers shipping a wide variety of products, poly mailing bags remain one of the most cost-effective, space-saving, and protective packaging solutions. Whether you're shipping tech accessories, health & beauty products, or handmade items, plastic mailing bags offer lightweight durability and reduce postage costs. These mailing bags are tamper-proof, waterproof, and come with peel-and-seal strips for fast, secure fulfilment perfect for growing eCommerce operations that need to move quickly and efficiently.

Clothing & Apparel

If you're shipping garments, you'll love our selection of mailing bags for clothes. Lightweight yet strong, our apparel shipping bags and grey mailing bags offer the perfect balance of cost-efficiency and style. Choose from sleek polymailers or branded plastic shipping bags to reflect your business identity while keeping postage costs low.



Sustainable Brands

If sustainability is a priority for your business, consider switching to paper mailing bags or mailing paper bags. These eco-friendly alternatives are made from recycled or FSC-certified paper and offer strong protection for lighter goods while being fully recyclable and biodegradable. Many of our eco mailing bags are also compostable, giving your customers a packaging experience that aligns with your brand values—without compromising performance or professionalism.

Books & Smaller Items

When it comes to shipping books, documents, small electronics, or accessories, lightweight plastic postage bags and smaller parcel bags offer the perfect solution. These compact bags are tough enough to withstand handling, yet thin and lightweight enough to minimise your shipping costs. Whether you're sending notebooks, DVDs, or mobile accessories, small postage bags help reduce excess packaging and improve the unboxing experience for your customers.



Bulky or Padded Products

Shipping products with irregular shapes or fragile contents? Our bubble wrap mailing envelopes and large parcel bags provide that extra layer of shock absorption and security. Lined with protective bubble wrap, these bags are ideal for cosmetics, electrical items, gifts, and other items prone to breakage. Choose padded mailing bags to ensure your goods arrive in perfect condition—especially for high-value or delicate orders that need more than just surface protection.

Extra-Large Orders

Need something bigger? Our extra large mailing bags and big postage bags are made for bulkier shipments. These heavy-duty plastic parcel bags are commonly used by wholesalers, fashion retailers, and fulfilment centres shipping jackets, multiple items, or boxed goods. With widths over 700mm and robust tear resistance, these extra large postage bags offer the size and strength needed for reliable shipping on a larger scale.
