Abstract: Due to the unqualified oxygen permeability of PET bottle itself, the quality problems of fruit juice and tea drinks, including brown oxidation, poor tastes and excessive flora, etc., have attracted more and more attention. Relevant manufacturers must control the oxygen transmission of the beverage PET bottles. Key words: oxygen permeability Tester, PET bottle, equal [...]
Yogurt is a food produced by bacterial fermentation of fresh milk. A large amount of protein, fat, vitamin and various beneficial bacteria are contained in the yogurt, which are easy to be digested and absorbed by the human body. Since the yogurt has a very short shelf life, the packaging material used for the yogurt [...]
Powdered milk or dried milk is a manufactured dairy product made by evaporating milk to dryness. One purpose of drying milk is to preserve it; milk powder has a far longer shelf life than liquid milk and does not need to be refrigerated, due to its low moisture content. In order to guarantee the quality [...]

Caramel treats is a kind of common pastry. It is made of flour, egg, sugar and nuts by deep frying. It is rich in nutrition and high in oil. It is easy to breed microorganisms and oxidize. In addition to strictly controlling the production process (such as adopting dynamic disinfection technology in its storage, transportation [...]
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 [...]
