Poštové tašky MAILmedia H18 biela 39 g veľkosť 290×370 mm

MAILmedia H18 White mailer bags are lightweight polyethylene poly mailers with an external size of 290×370 mm and a product weight of 39 g. The white surface provides a clean, uniform appearance for shipping documents, apparel and other light goods. The mailers feature a water-resistant exterior and a self-seal closure to simplify packing and protect contents during transit.

Advantages

These mailer bags combine low weight with a durable polyethylene film that resists moisture and punctures in normal postal handling. The self-adhesive strip enables fast sealing without tape, while the smooth white finish accepts printed labels or direct writing for easy addressing. Their compact dimensions and light mass help reduce postage costs for small parcels.

Suitable for

• Shipping lightweight clothing and textiles
• Mailing documents, catalogs and brochures
• Sending small e-commerce orders and returns
• Protecting non-fragile items from moisture and dirt

Key specifications

• Material: polyethylene film
• Color: white
• External dimensions: 290 × 370 mm
• Weight per bag: 39 g
• Closure type: self-seal adhesive strip
• Surface: smooth, writable/label-friendly
• Protection: water-resistant

How to use

Place the item inside the mailer, ensuring it lies flat and does not overfill the bag. Remove the protective liner from the adhesive strip and press the flap firmly onto the body of the bag to create a secure seal. Affix a shipping label or write the recipient address directly on the surface using a permanent marker or label. For heavier or fragile contents, use additional internal padding or choose a more protective packaging solution.

Recommendations

Store the mailers flat in a dry environment away from direct sunlight. Do not reuse damaged bags for shipping; inspect each mailer before sealing. When shipping items that require tamper evidence, consider adding a numbered label or using tamper-evident tape in addition to the self-seal closure.
