If you want to customize a backpack, you need to spend more time on choosing a manufacturer of custom schoolbags for primary school students. A good custom manufacturer of schoolbags for primary school students can not only provide you with goods, but also provide you with some co-ordinated services. Here, Hunan Dandan Leather Co., Ltd. introduces some knowledge to us, so that you can avoid some detours in the customization process. Below, let us talk about the factors that affect the quality of custom backpacks, and hope to help us.
1. Backpack body
The backpack body is mainly composed of main materials, ingredients, front panel (front panel), back panel (back panel), inner pocket, outer pocket, cap and other main parts. The fabric of the bag body is the biggest problem, and it is also the main component of the customized backpack. The product function of the backpack is mainly reflected in the fabric. After all, it is directly displayed. Abstractly speaking, backpacks are usually made of Oxford fabric, nylon fabric, or cotton fabric. For example, if you choose Oxford fabrics from the density, you can find hundreds of different markings and colors. If a backpack is made to work well, it shows that the manufacturer has already made a lot of effort in selecting the fabric.
2. Backpack shoulder strap
The shoulder strap of the backpack is a very important part. It not only gathers the items that you usually carry with you, but also can carry the weight. With the progress of production technology, most of the shoulder straps now have the functions of breathability, lightening, and beauty, and even some plans also have the function of storage and linking. The materials used for the shoulder straps are mostly Oxford cloth, mesh cloth, high-quality sponge, edging belt, webbing or leather, and some plastic or hardware accessories. If the shoulder straps are too short, the buckle part of the backpack will rush to the chest when it is back. It is a very uncomfortable feeling, which will seriously affect the beauty and the experience of the double back. In order to prevent the occurrence of this problem, the shoulder straps are generally not shorter than the height of the backpack or even slightly longer in the manufacturing process. Some backpacks need to plan the long shoulder straps into a curved shape, so as to increase the length without affecting the beauty.
3. Backpack zipper
The zipper of the backpack is composed of three parts, the zipper, the slider and the card. The two sides of the zipper are generally made of nylon raw materials. The zipper teeth in the middle are mainly divided into two types: rubber teeth and metal teeth. Distinguish the quality of a zipper, see if the teeth of the zipper fall off, pull the slider several times and feel whether the connection between the slider and the zipper is smooth. Twist a part of the zipper forcefully, and check for cracks in the zigzag part. Look at the connection gap between the pull card and the slider. If the gap is large, the pull card and the slider will simply break apart. Poor quality zippers are very simple to have problems, such as teething, concealing, and emptying. Therefore, a good backpack will never be used, it is a disregard and ruin of the package body and process.
4. Backpack hardware
Backpack hardware is generally divided into two types of “iron wire” and “alloy” according to the raw material. The detailed distinction can be distinguished by a magnet. The iron wire can be tightly attracted, and the alloy is not tightly attracted. The hardware of alloy raw materials is more delicate than the hardware of iron wire from the perspective of process effect. The iron wire appears rougher, and the alloy is a bit more expensive than the iron wire. The hardware of some backpacks rusted before long time, and the outer skin layer began to fall off, which directly affected the appearance of the backpack. This is the reason why no oil is added during hardware manufacturing. The hardware without sealing oil is easily oxidized and rusted, and the surface material of the hardware after sealing with oil is not simply oxidized with air. Hardware plays a finishing touch, and a good-quality backpack will not be equipped with poor hardware.
