How to distinguish the quality of glass wine bottles with the naked eye? What are the standards for distinguishing qualified glass wine bottles? The editor of QLT Glass Products Co., Ltd. will tell you about several main factors that affect the quality of glass wine bottles.
First of all, to distinguish the quality of a glass wine bottle, of course, a series of tests such as temperature difference testing and internal stress testing are required. When we get a glass wine bottle with a smooth and bright body without color difference, no broken threads or blown-out mouth on the bottle mouth, and a uniform thickness on the bottom of the bottle, and there are no significant defects on the whole body of the glass liquor bottle, then it can be considered a qualified glass wine bottle.
When looking at a glass wine bottle under bright light, if there are small bubbles of more than 3mm on the body of the bottle, the direct cause of this situation is that the internal stress of the glass wine bottle is not good, which is mainly caused by insufficient condensation pool temperature, resulting in insufficient condensation of glass materials. This is a serious product quality problem. If the mold has not been used for a long time, the surface may be oxidized or not cleaned before use, which will cause some impurities to adhere to the surface of the mold, making the produced glass wine bottle slightly uneven. Although this does not actually affect the quality, it severely affects the appearance.
In recent years, e-commerce has been booming, and many glass bottle manufacturers have also participated, including QLT Glass Products Co., Ltd., which is a professional enterprise specializing in the production of food-grade glass bottles. Before the pandemic, we mainly obtained customers through international exhibitions and local visits. Since the pandemic began, we have started to move online. Through more convenient communication with customers via the Internet, this has reduced travel frequency and at the same time improved communication efficiency. From 2019 to 2022, our order volume has increased significantly, and our high-quality glass bottles and jars have been certified by LFGB, SGS, and other quality certifications, and exported to Europe and America.
