Send Every Order Securely with 100 Self-Seal Mailing Bags

These 100 white poly mailing bags are made from polyethylene — a lightweight, water-resistant material that protects contents during transit. Each bag features a high-tack self-adhesive strip, letting you seal packages quickly without the need for extra tape or equipment. The opaque white exterior keeps contents hidden from view, which matters for customer privacy and presentation alike. Lightweight enough not to add significantly to your postage weight, the bags are suited to clothing, printed materials, and non-fragile products. Their flexible construction means they adapt to irregular shapes without tearing, and the seal holds firm even under pressure. A practical, no-fuss solution for regular online sellers, market traders, or anyone managing a steady flow of outgoing parcels.

  • Self-Adhesive Seal: High-tack strip closes each bag in seconds with no tape needed, cutting packaging time on large dispatch runs.
  • Water-Resistant PE Material: Polyethylene construction repels moisture, keeping contents dry during transit regardless of weather conditions.
  • Opaque White Exterior: Contents are fully hidden from view, protecting customer privacy and maintaining a clean, professional presentation.
  • Lightweight Construction: Minimal weight added to each parcel keeps postage costs from creeping up across high-volume sending.
  • Pack of 100: Bulk quantity means fewer reorders and a consistent supply on hand for steady e-commerce or small-business operations.

Practical Mailing Bags for Regular Senders

Built for E-Commerce and Small Business Use

What's in the Pack

What is included

These 100 white poly mailing bags are manufactured from polyethylene (PE) — a material chosen for its low weight and reliable moisture resistance. Each bag seals with a high-tack self-adhesive strip, removing the need for tape and keeping packaging time to a minimum.

The opaque white exterior conceals contents from view, which is useful for customer privacy and presenting a consistent, professional look. Flexible enough to accommodate irregular shapes, the bags suit clothing, printed materials, and small non-fragile goods. Lightweight construction means minimal impact on postage costs, making this pack well suited to sellers dispatching regular volumes.

Each pack contains 100 individual white self-seal mailing bags. No additional adhesive or equipment is required to seal them. The seal is single-use — once closed, the bag must be cut or torn to open, which provides a basic tamper-evident function useful for e-commerce dispatch.

Description and experienceShow

Running an e-commerce operation or small business means packaging time adds up quickly. These 100 white poly mailing bags address that directly: the high-tack self-adhesive strip seals each bag in a single press without reaching for tape, scissors, or a heat gun. The polyethylene material is lightweight enough to avoid adding meaningful weight to your postage costs, yet resistant to moisture so contents arrive dry even in poor weather. The opaque white exterior keeps product contents private — an important consideration for clothing sellers and gift retailers where the element of surprise matters. Flexible by nature, the bags accommodate non-standard shapes and thicker folded items without straining at the seams. For anyone managing a regular flow of outgoing orders, 100 bags in a single pack means fewer purchasing decisions and a consistent supply on hand. A dependable, straightforward packaging tool for the day-to-day reality of selling and dispatching online.

Guarantees, usage and supportShow

Technical review and performance

The bags use a single-layer polyethylene (PE) construction — a lightweight thermoplastic that provides reliable moisture resistance without significant weight addition. The high-tack adhesive strip is bonded along the interior of the sealing flap, creating a tamper-evident closure once pressed shut. PE is inherently flexible at ambient temperatures, allowing the bag to conform to irregular item shapes.

Expert take

What stands out with these mailing bags is the straightforward self-adhesive strip — it holds securely on first contact and doesn't require the kind of firm pressing that some cheaper alternatives demand. The PE construction is noticeably flexible without being flimsy; the material stretches slightly around awkward items without splitting at the seams. The white finish stays clean during storage, unlike grey or silver variants that show handling marks more readily. These bags are best suited to sellers dispatching clothing, accessories, or printed matter. They're not reinforced for particularly heavy or sharp items, so anything with rigid edges worth protecting is better served by a padded option. For everyday e-commerce dispatch — particularly clothing and soft goods — this pack covers a solid run of orders without fuss.

Highlighted features

  • Pack of 100 Mailers
  • Self-Adhesive Peel-and-Seal Strip
  • Water-Resistant PE Material
  • Lightweight Postal Packaging
  • Opaque White Exterior

Key benefits

  • Seal parcels in seconds without reaching for tape or additional tools
  • Protect contents from rain, splashes, and surface moisture in transit
  • Present every order professionally with a clean, opaque white exterior
  • Manage dispatch volume efficiently with 100 bags per pack

Usage recommendations

  • Load the item first, then peel the adhesive strip in a single smooth motion — a continuous peel is faster and reduces the chance of partial activation.
  • Use adhesive address labels rather than markers on high-volume dispatches — labels apply quicker and scan more reliably at couriers.
  • Flatten bags before storing to maximise space efficiency and keep the peel strip from making contact with other bags.

What's included

  • 100 x White Self-Seal Poly Mailing Bags

Materials and composition

  • Polyethylene (bag body and seal flap)

Care recommendations

  • Store unused bags flat in a dry location to prevent the adhesive strip from activating prematurely during storage.
  • Keep bags away from direct sunlight during long-term storage to maintain adhesive seal integrity.
  • Check the adhesive strip is fully peeled before sealing each bag to ensure a complete, even closure.

Frequently asked questions

Can the bags be reused once sealed?
No. The self-adhesive strip is a single-use peel-and-seal design. Once closed, the bag must be cut or torn to open.
Are the bags waterproof or water-resistant?
Water-resistant. PE poly mailers repel surface moisture and light rain effectively, but they are not designed for full immersion.
Can I write or print addresses directly on the bags?
Yes — the white PE surface accepts standard marker pens and adhesive address labels cleanly without smearing.
Are the bags recyclable?
PE mailing bags are recyclable at facilities that accept soft plastics. Check local council guidance, as kerbside collection for soft plastics varies by area.
What items are these bags best suited for?
Clothing, accessories, folded printed materials, and other flat or flexible non-fragile goods. Sharp, rigid, or particularly heavy items are better served by padded or rigid mailers.
