Non-sealing effect of beverage threaded cap and potential safety hazard

Did you know that the sealing structure of plastic beverage bottles does not protect the threaded part of the bottle mouth from hygiene, the threaded structure only has the tightening effect, not the sealing effect? Why can't beverage manufacturers pay attention to such a serious problem? Senior people said that this is because consumers do not know, manufacturers are reluctant to change the bottle mold in order to reduce costs.

Most bottled drinks are ready to drink. As you may have imagined, the threaded structure only has a tightening effect, not a sealing effect, and the bottle mouth is equivalent to exposed. At present, there are serious health and safety risks in the market of spiral-capped plastic bottle beverages, so it is not suitable to drink directly from the mouth to the mouth of the bottle.

For the plastic thread cap of beverage bottle, it may not only bring convenience to consumers. From the point of view of secondary contamination of food in transportation, storage and other links, because its thread structure and beverage bottle mouth are not sealed, it has become a weak link in food safety.

The first Financial Daily reporter found that the sealing structure of plastic beverage bottles in Shilong Town, Dongguan, can not protect the sanitation of the thread part of the bottle mouth. The threaded structure only has the tightening effect, not the sealing effect, which is almost an open secret in the packaging industry.

In the current food packaging standards, although there is no uniform standard requiring the spiral parts of beverage bottles to be sealed, and in the food packaging standards, the sealing and hygienic standards of the spiral parts of beverage bottle mouth are also in a blank state, for food safety, the secondary contamination of bottled beverages can not be underestimated.
