In our daily life, although the rubber cap is inconspicuous, but it has many important features and plays an unignorable role.
First of all, the rubber cap has excellent sealing. It is like a loyal guard, tightly guard the mouth of the container, the outside world of air, moisture and dust, etc. to keep out. Whether it is a precious wine, an important medicine or a delicate cosmetic, the cap ensures that its contents are not contaminated and that the quality remains stable. For volatile liquids, rubber caps can effectively prevent them from evaporating, so that the value of the product can be preserved for a long time.

Plastic bottle stoppers are bottle stoppers made of plastic materials (such as polyethylene or polypropylene) and are widely used in the packaging of various beverages, foods and medicines. Compared with traditional wooden stoppers, plastic bottle stoppers have many unique advantages.
Plastic bottle stoppers are widely used in:
Non-alcoholic beverages such as carbonated beverages and juices
Foods such as edible oils and condiments
Daily products such as medicines and cosmetics
In short, plastic bottle stoppers have become an indispensable part of modern packaging due to their excellent performance and economy.

Polymer cork is a sealing device made of polymer materials such as polyethylene, polypropylene, or polyvinyl chloride, widely used in bottled beverages, pharmaceuticals, cosmetics, and other fields. Compared with traditional natural stoppers, polymer stoppers have better sealing, corrosion resistance, and consistency, which can effectively prevent the infiltration of oxygen and moisture and extend the shelf life of products.
The production process of polymer cork is flexible, and its physical and chemical properties can be adjusted according to different needs. In addition, they usually have good mechanical strength and temperature resistance, adapting to various environmental conditions.
In terms of environmental protection, many polymer cork materials can be recycled and reused, which meets the requirements of sustainable development. With the development of technology and advances in materials science, the application areas and properties of polymer stoppers are constantly expandi

The T-cork is a specially designed bottle stopper that is shaped like the letter "T" and is mainly used for bottled beverages, especially certain types of alcohol. Its design makes it more stable when plugged into the bottle mouth, which helps to enhance the seal and prevent leakage.

With the popularity of fast-paced lifestyles, consumers have an increasing demand for food packaging that is easy to carry and use. This demand has prompted manufacturers to explore more practical packaging forms.
Advances in material science and packaging technology have made the production of self-supporting food bags possible. The use of lighter and stronger composite materials allows the bags to be self-supporting and effectively protect the food inside.
Self-supporting food bags are usually equipped with switch designs such as zippers, tear or press mouths, which are convenient for consumers to open and close, increasing the reusability of the product.
Many self-supporting food bags use recyclable or degradable materials, which meet the requirements of today's society for environmental protection and attract more consumers who focus on sustainable consumption.
Self-supporting food bags are widely used in snacks, dried fruits, coffee, condiments and other fields. Due to their good
