How to choose the bag is not heavy

The school bags on the market are full of beautiful things and powerful functions, but the functions of many school bags do not fully match the needs of students, and the design, structure, material and function of many school bags are unqualified, which brings a lot of troubles to thousands of parents of primary and middle school students in choosing school bags.


It is the norm for primary school students in China that little teenagers carry large schoolbags. As a parent, it is inevitable to have this worry: how can the child be exhausted by the heavy schoolbag? Indeed, too many books, poor bag design and the wrong way to carry the bag can easily lead to unnecessary injury to the child's spine.

Therefore, it is necessary to choose a high-quality and suitable school bag.

How do you choose a bag? Next, the designer of the student bag with light travel summarized the key points of the 9 election bags for everyone's reference.

01, the backplane and bottom of the bag should be hard

Some backplane, bottom plate texture of soft school bags, easy to produce a large deformation of weight when loading items, resulting in frequent changes in the center of gravity of the school bag, affecting the stability of the child's body center of gravity. A good quality school bag needs a hard backplane and bottom plate to ensure that it is not easy to deform when loading heavy objects, the center of gravity is stable, and the spine is not unnecessarily damaged.

02, the side of the bag should be thin enough

The bag purchased for the child cannot be too thick, and needs to be relatively thin. Thin bag limits the scope of the items in the bag to be swung back and forth, can make the position of the items in the bag relatively fixed, so that the center of gravity is maintained in a relatively stable state, reducing the burden of the spine caused by frequent changes in the center of gravity.


03, the bag internal center of gravity front

When placing books in the bag, try to put the weight close to the side of the body, so that the center of gravity of the bag is as close as possible to the center of gravity of the body, so that the torso can bear only one downward force as far as possible. If there is more after the center of gravity, there will be a force pulling back on the torso, resulting in the corresponding state of chest and hunchback.

04, the book placed on both sides of the same weight

When placing items in the bag, pay attention to keeping the weight on the left and right sides basically balanced. If the left and right sides are light and heavy, it is easy to cause the stress on the left and right shoulders to be unbalanced, and eventually let the child form high and low shoulders.

05, the content can be fixed, do not shake

When placing books in the bag, try to put the inside of the things stable, do not let him shake, if conditions can choose to buy internal with a fixed bag.

The purpose of doing so is to maintain the stability of the center of gravity, so that the spine is in a relatively balanced upright state, reduce the change of the center of gravity in the process of walking activities, avoid the resulting spinal fatigue, and then maintain the stability of the spine.

06, C shape stick back

The design of the C-shaped back can better fit the physiological curvature of our back, so that our thoracic vertebrae are better stressed. If it is flat on the back, in addition to the downward gravity of the bag, it will also form a forward force on the back, which is not conducive to the overall balance of the spine. In addition, the back of the bag is designed to fit the C-shape of the back, and the comfort is also higher.

07, back breathable

The back design of the bag should take into account the permeability of the bag, maintain the air flow, accelerate the evaporation of sweat, avoid sweating caused by the back heat in hot weather, and reduce the risk of cervical spondylosis caused by sudden cold after taking off the bag.

08, no pungent odor

When purchasing school bags, pay attention to observe whether there is a pungent smell inside the school bag. The Hygienic requirements for school bags of primary and secondary school students stipulate that the formaldehyde content should not exceed 300 mg/kg, and the maximum safe limit for lead is 90 mg/kg. If the bag has a severe pungent smell, it may be an unqualified product and may pose a threat to the child's health.

09, beautiful reflective

Of course, when buying school bags, we should also pay attention to the beauty of the appearance, choose a child's favorite school bag, TA will be happier on the way to school! Of course, in addition to the basic beauty, if this bag can reflect, it is most appropriate, because reflective bags, can make children travel to work safer, parents will be more assured.
