Why sellers choose iSOUL blue parcel bags
- Strong 60 micron film: thick enough to resist tearing in transit, yet light to keep postage costs down.
- Permanent self-seal strip: peel and press – no tape needed. Once sealed the parcel bag can't be opened without tearing, so parcels are tamper-evident.
- Fully opaque: blue outside, black inner lining, so nobody can see what's inside.
- Water and dirt resistant: protects items from rain and grime during delivery.
- Perfect parcel bags for clothes: ideal for posting clothing, accessories and other soft goods that don't need a box.
- Professional look: a clean, neutral blue that suits menswear, kidswear, tech accessories and business orders, and stands out more than plain grey.
- Works with all couriers: Royal Mail, Evri, DPD, Yodel, InPost and Vinted drop-off points.
Frequently asked questions
What's the difference between mailing bags and parcel bags?
None – they're the same thing. Mailing bags, parcel bags, postage bags, postal bags and poly mailers are all names for self-seal plastic bags used to post items.
What size parcel bag do I need for Vinted?
Most Vinted sellers use 10 x 14" for everyday clothing like dresses and jeans, 9 x 12" for T-shirts and tops, and 12 x 16" or larger for jumpers and coats.
Can I send these as a Royal Mail Large Letter?
The 6 x 9" and 9 x 12" bags can be, as long as the packed parcel stays within Royal Mail's Large Letter limits (353 x 250 x 25 mm, up to 750 g). Please check Royal Mail's current size rules before posting.
Are the bags see-through?
No. They're fully opaque with a black inner layer, so contents stay private.
Can I reopen and reseal them?
No. The seal is permanent for security, which keeps your parcel tamper-evident.
Are they waterproof?
They're water resistant and protect contents from rain and dirt in transit.
Can I write on them or use labels?
Yes. Shipping labels stick well and you can write on them with a permanent marker.
Is delivery free?
Yes, UK delivery is free on all orders, with no minimum spend.
