BSTech PollyMailers B4 Mailing Bags 260x350mm 50 Microns 50 Pieces

BSTech PollyMailers B4 mailing bags are professional-grade shipping envelopes engineered to provide reliable protection for your parcels during transit. Measuring 260x350mm with a robust 50-micron thickness, these bags are constructed from high-quality, moisture-resistant plastic that ensures your contents remain safe from environmental factors such as rain, dust, and dirt. The opaque material guarantees privacy for the items inside, making them a standard choice for secure shipping operations.

Advantages

These mailing bags offer exceptional durability and tear resistance, ensuring that your shipments arrive in pristine condition. Their lightweight design helps minimize shipping costs by adding negligible weight to your packages, while the moisture-resistant surface provides an essential barrier against the elements. The opaque finish ensures complete confidentiality, and the user-friendly design allows for quick and efficient packing, which is vital for high-volume shipping environments.

Suitable for

• Shipping documents and catalogs
• Sending clothing and soft goods
• E-commerce order fulfillment
• Logistics and courier services
• Small retail item distribution

These bags may not be suitable for shipping fragile, sharp, or heavy items that require rigid protection, such as glass, electronics, or metal components. They are designed for flexible items and are not intended to prevent crushing or impact damage.

Key specifications

• Dimensions: 260x350mm
• Thickness: 50 microns
• Material: Moisture-resistant opaque plastic
• Quantity: 50 pieces per pack
• Closure type: Self-sealing adhesive strip

To use these mailing bags, simply place your item inside the envelope, peel off the protective strip from the adhesive flap, and press firmly to seal the bag. Ensure that the flap is completely adhered to the surface to maintain a secure closure. For best results, avoid overstuffing the bag to ensure the adhesive seal remains intact during transit.

What to consider before purchase

• Verify that the dimensions are appropriate for your specific items
• Ensure the 50-micron thickness meets your durability requirements
• Check if the items being shipped require additional padding

For optimal security, ensure the shipping label is applied to a flat, clean surface of the bag and that the adhesive seal is pressed firmly across the entire width of the flap before handing the package to the courier.
