Computer backpacks are used to protect and equip laptops. Since laptops are relatively fragile, they may be broken if you are not careful later. Therefore, when choosing a computer backpack, you must pay attention to quality issues, so as not to buy it when the time comes. To a backpack of poor quality, and then break the computer. Today, Leimande luggage customization manufacturers will tell you that you must pay attention to the two accessories of computer backpacks.

　　1. Handle

　　The handle is one of the places where the computer backpack is tested by gravity, and it is often the most fatal detail here. There are two types of computer backpack handles, one is an aluminum handle, and the other is a nylon handle.

　　The aluminum alloy handle depends on whether the aluminum alloy does not fade. Knock the surface with your hand to see if there is a hollow sound. If so, it means that the aluminum alloy is not penetrated into the webbing, which is not enough for reinforcement. The second is to look at the grip. If the handle is full, it can fit the human body handle system; the third is to pull, pull it once to three times, and test whether the webbing in the handle is tight with the top of the bag to be used for a long time.

　　Let's look at the nylon handle. Nylon handles are used in traditional computer backpack styles. Nylon with higher density is durable and has guaranteed quality. In addition to its own quality, nylon handles should be selected with larger handles so that they are not easy to be strangled when picking them up; let’s look at them again. It is the tightness of the nylon handle and the top of the bag. It is more important to check whether the seam has secondary reinforcement.

　　2. Zipper slider

　　The zippers of computer backpacks are generally used for business models to show rigor and fashion, so computer backpacks basically use No. 5 zippers, which are exquisite and tight. of. Next is the water resistance of zippers. Waterproof nylon zippers are commonly used, because nylon itself does not absorb water, and it is developed using nylon materials. The main test method is the degree of compression.

　　If you choose a plastic slider for the slider of the computer backpack, check its firmness; if you choose a metal slider, check its metal density; and the silicone slider needs to check its toughness. The slider is actually one of the design features of the backpack. Its design is to use a double slider design. The opening of the backpack can be opened and closed from both sides, which is convenient to use, thus reducing the long-term damage of the slider and lengthening shorten the life of the zipper.
