Protective Poly Mailer Bags LEANToys Folia Kurierska Foliopak 100 pcs 250×350 mm

Poly mailer bags LEANToys Folia Kurierska Foliopak 100 pcs 250×350 mm are lightweight polyethylene envelopes designed for secure shipment and protection of soft, non-fragile items. Each envelope measures 250×350 mm and features a self-seal adhesive strip for fast closure. The pack contains 100 units suitable for regular e-commerce parcels, returns and document shipping where low weight and moisture resistance are priorities.

Advantages

These mailer bags combine low weight with tear-resistant film to reduce postage costs while maintaining protection against dirt and light moisture. The self-adhesive closure provides consistent sealing without tape, speeding up packing operations. Their smooth surface supports clear labelling and barcode scanning, and the opaque material helps preserve privacy of contents during transit.

Suitable for

• Clothing and textile items such as T-shirts, scarves and underwear
• Lightweight accessories and soft goods like hats, gloves and wallets
• Printed materials and documents that do not require rigid protection
• Small e-commerce orders and returns where reduced parcel weight is desired

How to use

Insert the item into the mailer bag so it lies flat and centered to avoid pressure points. Remove the protective strip from the adhesive and press the flap firmly to seal the envelope. Affix shipping labels or print directly on the surface in the designated area. For fragile or breakable contents, use padded or rigid packaging instead — these mailers are intended for soft, non-fragile items.

Usage recommendations

Store the mailer bags in a cool, dry place away from direct sunlight to preserve the adhesive strip and film strength. For secure transit, avoid overfilling; leave sufficient room to allow the seal to adhere evenly. When shipping valuable items, combine with internal padding or use a secondary protective layer to ensure adequate protection.
