Product Information

Full details

The YUNJU 50-piece mixed size mailing bag set is designed for small business owners and frequent shippers who require a versatile, opaque, and durable solution for sending parcels. These bags provide a professional shipping experience with high-performance 55mu thickness and secure self-seal strips, though the lack of interior cushioning means they are better suited for soft goods or items that do not require shock protection.

FAQs

Are these bags padded?

No, these are standard mailing bags and do not feature bubble wrap or foam padding.

Can I use these for international shipping?

Yes, their durable design is suitable for standard postal services, provided the items inside are not fragile.

Will the ink from shipping labels rub off?

The surface is compatible with standard adhesive shipping labels; it is recommended to apply labels to a flat area on the bag.

How many bags are in the pack?

This set includes a total of 50 bags across the three provided sizes.

Are the bags waterproof?

The material is water-resistant and will protect contents from splashes and light rain, but it is not intended for submersion.

Troubleshooting

Adhesive strip is not sticking properly

Ensure the bag surface is free from dust or lint before peeling the adhesive cover and pressing firmly along the seal line.

Bag punctured during shipping

Use protective wrapping or cardboard stiffeners inside the bag for items that have corners or edges to prevent the contents from piercing the plastic.

Pros and Cons

Pros

  • Variety of sizes in a single pack
  • Strong, reliable adhesive strip
  • Completely opaque material keeps contents private
  • Durable 55mu thickness resists tearing
  • Lightweight design helps reduce postage costs

Cons

  • No bubble lining for fragile items
  • Plastic material is not suitable for sharp or heavy rigid objects
  • Limited to three specific size increments

Setup, Compatibility & Care

Using these mailing bags is straightforward. Simply insert your item into the appropriately sized bag, peel the protective strip off the adhesive flap, and fold the flap down firmly to seal the edge. Ensure that the bag is not overstuffed, as this can put unnecessary stress on the seals. For storage, keep the bags in a cool, dry place away from direct sunlight to maintain the integrity of the adhesive strip. These bags are compatible with all major shipping labels; ensure the surface is clean and dry before applying adhesive labels for the best adhesion.
