Powder milk, which contains high content of oil and protein, should be packed in the packages with high barrier property. Aluminum plastic package is one of the main packages used for milk powder, which will be elaborated in this article. Generally, the above-mentioned aluminum plastic packages come in MAP (Modified Atmosphere Packaging) form, where the [...]

Fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), precursors of certain eicosanoids that are known to reduce inflammation in the body and have other health benefits. EPA and DHA contained in the fish oil are unsaturated fatty [...]

Instant noodles are a precooked and usually dried noodle block, sold with flavoring powder and/or seasoning oil, usually in a separate packet. In the early days, plastic composite package and aluminum plastic package are the main packaging forms for the instant noodle. Today cup noodles have become very popular because of its edible convenience especially [...]

There is a variety of facial masks on the market. The main materials used for facial mask include non-woven fabrics, cotton, paper pulp, bio-fiber and silk, etc. As the facial mask is applied directly on the skin, it must have a very good air permeability to allow the breathing of the skin. Such skin problems [...]

Artificial skin is a product which can be used for temporary or permanent replacement of damaged skin. Classically, doctors use synthetic skin on burn victims. There are a number of different types of artificial skin, ranging from sheets of human skin grown from the patient’s own cells to entirely synthetic products which are designed to [...]

Liquid milk is an important part of many people’s diet. Since a large amount of fat and protein are contained in milk, it is easily oxidized and, as a result, the quality of the milk can be compromised within its shelf life. A main cause of oxidation is potentially thepoor oxygen barrier property of the [...]

Basically, the amount of permeability, diffusivity and solubility of O2 and CO2 through polymers were affected by temperature, pressure and film thickness. the amount of permeability and solubility were decreased by increasing film thickness but diffusivity was increased. However, by increasing temperature, permeability, solubility, and diffusivity were increased. What about the specific and accurate data [...]

The air resistance of paper may be used as an indirect indicator of Z-directional fluid permeance, as well as other variables such as: degree of refining, absorbency (penetration of oil, water, etc.), apparent specific gravity, and filtering efficiency for liquids or gases. Air resistance is influenced by the internal structure and also the surface finish [...]

In Equal-pressure method gas permeability test standard ASTM D3985, it is specified that calibrations should use referential material provided by NIST. However, many standard executors do not fully understand the material of such referential medium and the method to obtain its standard value. This article presents a detailed introduction to the traceability of referential material [...]

GTR, gas transmission rate, is the rate at which a specified gas permeates through a stated area of a specimen under certain time period, pressure and temperature condition.  OTR, oxygen transmission rate is the rate at which oxygen transmits through a stated area of a specimen under certain time period. The above mentioned transmission can [...]
