How to choose courier envelopes
Polyethylene courier envelopes (mailing bags) are used for items that do not break: clothes, textiles, documents, accessories, small parts packed individually. They are light, water resistant and close with a self-adhesive strip. To choose correctly, check the usable size, thickness, opacity and closure type.
Usable size and flap
The size of an envelope is usually written as width × length + flap, for example 25 × 35 + 4 cm:
- the width is the side with the opening;
- the usable length is the distance from the bottom to the closing line, meaning the space the product goes into;
- the flap is the part with the adhesive strip that folds over the opening; it adds no space for the product.
Some manufacturers give the total length, including the flap. If the product page shows a single length value, check whether it is the usable or the total length. In our shop, the usable size and the flap are stated separately.

How to choose courier envelopes
- Size: 13 formats, from 180x255mm up to 800x1000mm, with a 50mm adhesive flap
- Thickness: between 45 and 70 microns — pick the thicker option for heavier or bulkier parcels
- Material: opaque, co-extruded white/black LDPE, keeping the contents private
- Closure: permanent adhesive tape, for quick and secure sealing
Courier envelopes suit parcel shipping through courier companies, online shops and warehouses sending out daily orders, whether for clothing and textiles or for smaller items and documents that don't need rigid protection. The per-piece price drops noticeably at larger volumes, starting from a minimum of 100 pieces, and the permanent adhesive flap seals the parcel quickly without extra tape.
