First of all, it can be distinguished from the appearance. The surface of a high-quality Non-Woven Vest Bag is smooth, without obvious wrinkles, damage or stains. The fabric has a uniform texture and a natural and soft color, without uneven color or fading. However, a low-quality Non-Woven Vest Bag may have a rough surface, obvious flaws, and the color may be too bright or dull, or even easy to fade during use.
Secondly, the material is an important basis for judgment. High-quality non-woven fabrics are usually made of polymer materials such as polypropylene, which have good flexibility and strength. Gently pull it with your hands, and the high-quality bag is not easy to deform or break, and you can feel a certain toughness and elasticity. However, the low-quality non-woven fabric may be thinner and more brittle, and it is easy to break if you pull it a little harder. At the same time, high-quality non-woven fabrics feel softer and more comfortable, while low-quality ones may feel rough and prickly.
In addition, check the workmanship details. High-quality Non-Woven Vest Bags are finely sewn, with even and neat stitches, without problems such as unthreading and skipping. The edges of the bag are also smooth, without burrs or unevenness. The workmanship of inferior products is often rough, the stitches may be of different sizes, and the edges may be handled carelessly.
You can also distinguish by smelling. High-quality Non-Woven Vest Bags generally have no irritating odor because they use environmentally friendly materials and production processes. Inferior bags may have a pungent chemical odor, which may be due to the use of inferior materials or the addition of too many chemical additives.
In addition, consider the load-bearing capacity of the bag. High-quality Non-Woven Vest Bags usually have good load-bearing performance and can withstand a certain weight of items without breaking or deforming. You can do a simple test when buying, put in an appropriate amount of items to observe the performance of the bag.
Finally, check the product's logo and certification. Regular high-quality Non-Woven Vest Bags usually have clear information such as the manufacturer, material description, environmental protection logo, and may also pass some relevant quality certifications. Inferior products often lack these standardized logos.
In short, by observing the appearance, checking the material, paying attention to the workmanship details, smelling the odor, testing the load-bearing capacity and checking the logo certification, you can more accurately distinguish between high-quality Non-Woven Vest Bags and inferior products, so as to choose more environmentally friendly and durable packaging products.
