At present, there are two types of multi-chamber large volume IV bags, one is liquid-liquid multi-chamber bags, the other is powder-liquid multi-chamber bags: it refers to that different IV drugs are packed in the same package in the production process, storage and transportation process, separated in different chambers by sealing, the seal is opened by [...]
Rubber is widely used in aerospace, weaponry and equipment, automobiles, ship, delicate machinery, petrochemical industry, electricity and many other fields. It is easily damaged by light, heat, rain, snow, oxidization, physical stresses and chemical corrosion and other environmental and external forces. Rubber is prone to aging, which means its chemical structure is damaged, its appearance [...]
Common food sterilization processes include high-temperature sterilization, low-temperature sterilization, high-pressure sterilization, irradiation sterilization, microwave sterilization, UV sterilization and etc. Generally, the sterilization is carried out after the completion of food packaging, which means the materials used for packaging is also sterilized. This requires that when choosing sterilization process or selecting packaging materials, not only the [...]
For packaging materials with the same material structure, the thickness of materials is an important factor affecting their barrier performance. With the increase of material thickness, the gas permeation path in packaging material is prolonged, and the time of gas permeating from one side to the other side of the sample is increased, the amount [...]
Gas barrier performance is an important research field of thin film materials. According to different applications, gas barrier performance of thin film materials can be divided into barrier or preservation ability of oxygen, nitrogen, carbon dioxide, helium, water vapor, sulfur hexafluoride and other gases, due to the molecular diameter of gases, critical temperature, gas molecules [...]
Instant noodles are a precooked and usually dried noodle block, sold with flavoring powder and/or seasoning oil, usually in a separate packet.

Dairy drinks are very common consumer products in people’s daily life. Peanut milk, walnut milk and many other beverage containing milk are very popular. Dairy milk is mainly made of fresh milk, which contains a large amount of protein, vitamin and fat. Those nutrients are liable to be oxidized, which should be kept away from [...]
The basic principle of warm paste’s mechanism is to convert chemical energy into heat through the oxidation-reduction reaction participated by oxygen. The amount of oxygen is an important factor affecting the rate of the reaction. A large amount of oxygen will result in strong reactions and release a large amount of heat in a short [...]
Some instant foods are usually made by deep frying. They have a high content of grease and a low moisture. Therefore, in order to prevent the oxidation and deterioration of oil, the generation of harmful substances, stale flavor due to contact with oxygen or light during the storage of instant foods, or the appearance of [...]
