Lähetyspussi MAILmedia B4 itseliimautuva valkoinen 100 g/m²

MAILmedia B4 self-adhesive white 100 g/m² mailing bag is a paper envelope sized for B4 documents and flat items. Constructed from 100 g/m² white paper, the bag provides light protection while keeping weight low for economical postage. A peel-and-seal adhesive strip secures the closure quickly without additional tape or glue, making the product suitable for routine office dispatches, e-commerce shipments and general correspondence.

Advantages

The mailing bag combines a B4 format that fits common document sizes with 100 g/m² paper that balances rigidity and flexibility. The peel-and-seal adhesive strip speeds up packing and ensures a consistent, tamper-evident closure. The white paper surface is suitable for writing, labeling or applying address labels and printing directly with compatible printing systems. Its lightweight construction reduces shipping costs compared with heavier alternatives.

Suitable for

• Dispatching B4-format documents, brochures and certificates
• E-commerce shipments of flat goods such as calendars, prints or thin catalogs
• Office correspondence where a quick, secure closure is required
• Mailings that prioritize low postage weight and straightforward handling

How to use

Insert the document or flat item into the bag so it lies flat and centered. Remove the protective liner from the peel-and-seal adhesive strip, press the flap firmly along the sealing edge to engage the adhesive and ensure a secure closure. For added protection, use an address label or write the recipient details on the paper surface. Store unused bags in a dry, flat place to prevent creasing or moisture damage.

Recommendations

For best results, avoid overfilling the bag beyond the dimensions of B4 items and the capacity of the flap; excessive thickness can prevent full contact of the adhesive strip. When sending through automated sorting or printing systems, verify compatibility with your printer or feeder and use appropriate labeling to ensure clear addressing.
