Many people have already got some knowledge about our disposable plastic cover wholesalers, Hebei, Shijiazhuang, Tianjin, etc., and also introduced the disposable plastic cover to you. Today's editor will introduce to you "the performance characteristics of plastic cover plastic cover distinguish good from bad", hoping to help you
The performance characteristics of plastic cover: 1. The top and inner wall of general plastic cover are provided with a ring-shaped leak proof ring; there are also general plastic barrel covers that need to be matched with the inner cover, so there is no need to design the leak proof ring;
2. The lower end of the plastic cover is connected with an anti-theft ring through a tensile reinforcement;
3. At the same time, several pieces of gyrotron wings are evenly distributed on the inner wall of the guard ring;
The plastic lid designed in this way has the advantages of firm sealing, good leakproof and anti-theft performance, safe and convenient use, and can effectively prevent the liquid in the container from being polluted by the outside. The performance characteristics of the plastic lid can ensure that the packaging of various liquid products meet the national security standards.
Plastic caps can be identified by smell. In general, the original plastic has fragrance, while the recycled plastic has an unpleasant smell. The recycled plastic is toxic and pollutes the environment. The plastic caps of the same size are generally made of light new plastic, and the waste plastic will be heavier because of the quality of the magazines. Generally, the plastic products of large supermarkets and regular shopping malls are relatively reliable, and the roadside is small Shops and booths in the small commodity market with very low prices should be careful when purchasing; the color of the new plastic is pure and high purity, while the old plastic is mostly dark and the color is not correct. In short, the raw material is generally transparent. The recycled material can't be transparent. Many colors are mixed together, with black as the main color. The raw material has good toughness, the chair made of it has good bearing capacity, and the basin made of it is resistant to falling, while the recycled material has poor toughness, is brittle and easy to break. Especially the waste plastics whose properties are identified by plastic cover and recycled for many times are easier to be aged. Through these methods, we can judge the quality of plastic cap.
