How does the handle design of a disposable plastic bag improve its load-bearing capacity?

Publish Time: 2024-11-05
The handle design of a disposable plastic bag is crucial to improving its load-bearing capacity, which involves multiple considerations.

First, the width of the handle is a key factor. A wider handle can distribute the weight of the item being carried more evenly on the user's hand. When we carry heavier items, a wide handle can reduce pressure and avoid the handle from being strangled or broken due to concentrated pressure. For example, a handle with a design width of 3-5 cm can significantly improve comfort and load-bearing limits compared to a narrow handle.

The thickness of the handle should not be ignored either. Increasing the thickness of the handle can enhance its own strength. The thickness of the handle can be increased by using a multi-layer plastic composite method, or thicker plastic raw materials can be used in the manufacturing process of the handle. Thick handles are not easily stretched and deformed when bearing heavy objects, and can better maintain their shape and structure, thereby ensuring safety and reliability under heavy weight.

The connection method between the handle and the bag body is equally important. Use strong heat-sealing technology or enhanced bonding technology to form a solid connection between the handle and the bag body. For example, add additional plastic reinforcement sheets at the connection, or design special connection structures, such as nested or embedded connections, so that the connection between the handle and the bag body can withstand greater tension and prevent the handle from falling off the bag body during load-bearing.

In addition, the shape of the handle can also be optimized. It can be designed into an arc or a certain angle shape, which conforms to the principle of ergonomics. When we carry heavy objects, the arc handle can better fit the hand, make the force distribution more reasonable, reduce local pressure, and at the same time enhance the load-bearing capacity of the handle to a certain extent, so that the disposable plastic bag can still be used conveniently and safely when loaded with more items.
