Use Of Pre-Opened Plastic Mailing Bags
Choose the right mailing bag
Choose the right size and type of mailing bag, depending on the size, weight and nature of the items you are mailing. Mailing bags come in different materials, thicknesses and features, such as waterproof, tear-proof or tamper-proof. Make sure the bag is strong enough to protect the items in the package.
Place the items in the mailing bag
Place the items to be sent neatly in the mailing bag. If they are fragile or sensitive items, you can add a layer of protective material such as foam or bubble wrap to the outside of the items to increase cushioning and protection. Make sure that the items will not be damaged by transportation bumps after being placed in the bag.
Check the bag opening
Make sure the items are completely placed in the bag and the bag has no tears or gaps. If the mailing bag has additional inner pockets or compartments, confirm that all items have been placed in the correct position.
Seal the bag opening
Most mailing bags come with self-sealing tape or sealing strips. Tear off the protective layer of tape and press the bag opening tightly to ensure a good seal. Once sealed, courier bags usually cannot be reopened, which helps prevent tampering.
Attach the recipient information
Clearly mark the details of the recipient and sender on the front of the mailing bag. You can write directly on the bag, or attach the address label or courier slip to the surface of the bag. If the bag is made of smooth material, use a suitable label or courier slip to ensure that it will not fall off or blur during transportation.
Attach the courier slip or label
Usually, the courier company will provide a courier slip, which you need to attach to the mailing bag. If there is a special transparent bag or area on the mailing bag to place the courier slip, you can insert the courier slip into it.
Submit to the courier company
After packaging, hand over the mailing bag to the courier company or logistics service point. Most courier companies also provide door-to-door pickup services, and you can make an appointment for the courier to pick up the package at your door.
Track the package
After mailing, keep the tracking number on the courier slip. You can track the progress of the package at any time through the online system provided by the courier company to ensure the safe delivery of the package.
Tips for Use Of Pre-Opened Plastic Mailing Bags
Heavy items
If the items you are mailing are heavy, choose a thicker mailing bag to prevent the bag from breaking during transportation.
Document mailing
When sending documents, you can choose a mailing bag with a special document compartment to prevent the documents from bending or being damaged.
Waterproof protection
Although most mailing bags are waterproof, for valuable or important items, you can wrap the items in a waterproof bag or plastic bag for additional protection.
