Double Adhesive Self-Sealing Courier Bags – Waterproof Poly Mailers for E-commerce Shipping

Advantages of double - adhesive - strip express bags

1. Repeated opening and secondary sealing are possible

If the bag needs to be opened again after the first sealing (for example, the seller sent the wrong goods and needs to adjust the contents, the buyer needs to take out the goods for return, or for customs inspection, etc.), just carefully tear off the first adhesive strip on the outside (without damaging the bag itself). After taking out or putting in the goods, directly use the second adhesive strip on the inside for re - sealing.

2. Enhanced sealing and safety

Anti - theft and anti - tampering: If the outer adhesive strip is torn, it will leave obvious marks, and the recipient can easily find that the package may have been opened midway, improving safety. The inner adhesive strip ensures the safety of the contents after secondary sealing.
Double - layer sealing: The two adhesive strips provide double - layer protection, which is more effective in preventing accidental opening during transportation than a single - adhesive - strip or ordinary tape sealing.

3. Convenient and efficient operation

Easy to open: Recipients usually only need to tear along the indication of the outer adhesive strip to easily take out the goods, providing a better experience.
No additional tools required: Whether it is the first sealing or the secondary sealing, no additional tape or tools are needed. Just tear off the protective film and stick it directly.

4. Improved moisture - proof and dust - proof performance

The tight fit of the two adhesive strips usually makes the sealing at the bag mouth better than that of a single - tape sealing. It can better block outside moisture and dust from entering the bag, providing better protection for the contents (especially for items that require a certain degree of moisture - proof).

5. Neat and professional appearance

The double - adhesive - strip design itself is relatively regular. After sealing, the appearance is flat and beautiful, making it look more professional and reliable. After secondary sealing, the inner adhesive strip can also maintain a relatively neat appearance (unlike repeated pasting with ordinary tape, which is messy).
