Wholesale PT Lids

The PT cap achieves a sealing effect by having the thickened PT material inside bite the bottle mouth thread. This design can effectively prevent the infiltration of air, moisture and microorganisms, thereby better maintaining the quality and freshness of the product. Compared with ordinary tinplate lids, PT lids will not be tightened a second time after opening, which is safer and more convenient for your brand to maintain quality control. It is very suitable for some high-end edible health products, such as ready-to-eat bird's nest, oats and other nutritional products. The PT cap is heat-resistant, chemically resistant and not prone to rust. In contrast, some ordinary bottle caps (such as tinplate caps) may rust due to coating issues, affecting product quality.
