Square bottom plastic bags are widely used in logistics transportation, but if appropriate measures are not taken, their contents are prone to dumping or leaking, which will not only cause cargo loss, but may also affect the transportation environment and other goods. Therefore, it is crucial to take effective protective measures.
Choose a square bottom plastic bag of appropriate size and sufficient strength according to the volume, weight and characteristics of the items to be packed. For heavier or leak-prone items, thick-walled, high-strength plastic bags should be selected, such as bags made of high-density polyethylene (HDPE), which have good toughness and puncture resistance, can withstand heavy weight and are not easy to break.
Before putting items into square bottom plastic bags, pre-treat and package the items reasonably. For liquid items, ensure that the container is well sealed and there is no risk of leakage. You can wrap a layer of cushioning material such as bubble film or sponge outside the container to reduce collision and friction during transportation. For irregularly shaped items, you can fix them with paper boxes or foam boxes, and then put them in plastic bags to prevent the items from shaking in the bag and causing the bag to break.
When putting items into square bottom plastic bags, do not overfill them. Leave some space to prevent the bags from bursting due to squeezing during transportation. At the same time, make sure the bags are firmly sealed. Heat sealing, tying or clip zipper can be used to seal the bags. Heat sealing is a more common method that can form a firm seal to prevent leakage of the contents. For some bags that need to be opened and closed multiple times, clip zipper sealing is more suitable, but check whether the clip zipper is intact to ensure the sealing effect.
When placing the square bottom plastic bag with items in the transport package, use cushioning materials to fill and fix it. Foam boards, air cushions or waste paper can be placed around the bag to cushion the impact during transportation. If multiple bags are transported together, they can be neatly arranged and fixed together with tape or ropes to reduce the relative movement between bags.
Choose the appropriate transportation method according to the nature of the items and the transportation distance. For fragile or leaky items, try to choose a stable transportation method, such as express truck or air transportation. At the same time, put the square bottom plastic bag into a suitable outer packaging container, such as a carton, plastic box, etc. The carton should have sufficient strength and hardness to protect the bag from external squeezing and collision.
Make clear signs and warnings on the transport packaging, indicate the nature of the items in the bag, fragility or easy leakage, and remind the transport personnel to be careful during handling and loading and unloading. This can avoid the contents from being dumped or leaked due to human negligence.
In logistics transportation, square bottom plastic bags need to prevent the contents from being dumped or leaked from multiple aspects, including choosing suitable bags, packaging items reasonably, sealing correctly, using buffering and fixing measures, choosing suitable transportation methods and packaging containers, and making good signs and warnings. Through the implementation of these comprehensive measures, the risk of contents being dumped or leaked can be effectively reduced, ensuring the safety and integrity of the goods during transportation.
