Envelopes de envio MAILmedia I19 branco 56 g, tamanho 320×455 mm

MAILmedia I19 White poly mailer, weight 56 g and dimensions 320×455 mm, is a lightweight mailing bag designed to protect textile goods and similar soft items during shipment. The smooth opaque white exterior conceals contents for privacy, while the water-resistant plastic material reduces the risk of moisture and dirt reaching the parcel. A self-sealing adhesive strip simplifies closure and speeds up packing workflows for e‑commerce and retail returns.

Advantages

These poly mailer envelopes combine low weight with tear-resistant construction to keep postage costs down while offering reliable basic protection. The self-seal closure eliminates the need for tape and accelerates packing. Opaque white finish provides discreet presentation and easy labelling. The flexible design adapts to irregularly shaped soft items without adding bulk.

Suitable for

• Shipping clothing items such as t-shirts, underwear and lightweight knitwear
• Sending soft accessories like scarves, gloves and hats
• Returns and exchanges for online retail
• Mail-order shipments and marketplace sales

How to use

Place the packed item into the mailer so it lies flat without overfilling; fold excess film if necessary to keep the parcel compact. Remove the protective liner from the adhesive strip and press firmly along the closure to seal. For extra security or heavy items, reinforce the closure with tape. Affix shipping labels or print directly on the mailer surface in the designated area.

Recommendations

For best results, select the mailer size that allows a snug fit without stretching the film. Avoid sharp objects that can puncture the envelope and consider an internal protective layer for fragile items. Store mailers flat in a dry environment away from direct sunlight to preserve adhesive performance and material integrity.
