Measuring 190x250mm and featuring a 50-micron thickness, these opaque poly mailers offer a balance of durability and lightweight construction, ensuring your shipments remain protected during transit while keeping postage costs efficient.

Advantages

These mailing bags are constructed from high-quality, moisture-resistant material that shields contents from rain, dust, and dirt during the delivery process. The opaque finish ensures complete privacy for the items inside, preventing visibility of the contents. The strong adhesive strip provides a permanent seal, offering tamper-evident security that gives both the sender and the recipient peace of mind. Their lightweight design helps minimize shipping weight, which is particularly beneficial for high-volume e-commerce operations.

These bags may not be suitable for shipping fragile, sharp, or heavy items that require rigid protection, such as glass, electronics, or bulky hardware. They are designed for flexible items and are not intended to provide impact resistance for delicate goods.

How to use

To use the BSTech PollyMailers, simply place your item inside the bag, ensuring it does not exceed the dimensions or weight capacity. Remove the protective strip from the adhesive flap, fold the flap over, and press firmly across the entire width to create a secure, airtight seal. Ensure the surface is clean before applying the label to guarantee it adheres properly.

What to consider before purchase

• Verify that your items fit within the 190x250mm dimensions
• Ensure the items are not sharp enough to puncture the 50-micron material
• Consider the weight of your items to ensure they are appropriate for flexible packaging

Usage recommendations

For optimal results, avoid overstuffing the bags, as this can stress the seams and compromise the integrity of the seal. Always ensure the shipping label is applied to a flat, smooth area of the bag for better readability by scanning equipment.
