Improving the wettability of aluminum foil with oxygen plasma treatments. Apr 2, 2012 The wettability of aluminum foil is an important concern in many industrial converting processes. X-ray photoelectron spectroscopy (XPS or A PROCESS FOR PRODUCING HIGHLY WETTABLE ALUMINUM However, the wettability of the aluminum as measured.
The wettability of aluminum foil is an important concern in many industrial converting processes. X-ray photoelectron spectroscopy (XPS or ESCA) and water contact angle results indicated that relatively mild (i.e. 250 W, 15 s) oxygen plasma treatments efficiently removed residual carbon contamination from cold-rolled foil surfaces.
Cited by: 22Aluminum foil production involves cold rolling strip in subsequent rolling steps to reduce the thickness by almost half in each step. The strip for cold rolling can originate from continuously cast ingots that have been hot rolled to a thin strip or from continuously cast strip in a thickness of approximately 2-4 mm.
Aluminium foil quality: surface analysis. It can detect the presence of hydrocarbon products on the surface and the state of hydration of the outermost oxide layer. The nature of the oxide layer has a strong impact on coating adhesion. Any changes to it during processing, transportation and storage can
4. Wettability The foil must have a wettability A or A-B, whereas the surface of the fully annealed foil is assessed according to its ability to be wetted by liquids, applied under clearly defined conditions. The wettability index is shown by the shape of the trace given on the surface taken from the worst area of the foil.
Apr 23, 2014· Aluminum Foil Inspection and Quality Control Tests: The wettability test is performed when you need to determine the dryness of the aluminum foil. During this test various ethyl alcohol / water solutions are poured onto the aluminum foil surface. If no droplets form on the piece of aluminum foil, the wettability will be classified as zero.
Where aluminium foil is utalized Look around and you will find aluminium foil packaging in so many products, innerliner for cigarette packets ( aluminium foil with paper), aluminium tops for sealing yoghurt or butter cups, caps for milk bottles, beer bottle labels, medical packaging for push-out pills ( blister packaging ) or sachets for powder, aluminium foil in the kitchen for cooking or for the
The foil shall conform to the chemical composition requirements prescribed for aluminum, silicon and iron, copper, manganese, magnesium, zinc, vanadium, and titanium, and shall meet the specified requirements for tensile breaking load, direct current electrical resistance, and area per unit weight.
In these applications, the general requirements of the aluminum foil surface to be printed or composite, so the surface wetting tension value is the aluminum foil, especially the H18 state of aluminum foil (such as foil, battery foil) is a very important technical indicators
Aluminum foil (very thin sheeting of thickness from 0.00017 inch–4 µ to 0.0059 inch–150 µ) became a commercial reality in the early twentieth century as it replaced the stiffer tin foil used previously as a barrier wrapper for cigarettes. Use as a wrapper for food (chocolate and tea) followed shortly after that [1]. The material is unique in providing essentially complete barrier to light, oxygen, or water vapor
In the form of a coil, most hard aluminum foil undergoes annealing to re-crystallize the grain structure and remove the rolling oil. In addition to these tasks, the main purpose of annealing is to generate a surface that has even wettability with high chemical resistance and provides consistent adhesion properties.
Aluminium Foil is supplied completely sterile thanks to the metal annealing process during manufacture. It is non-hazardous to health, contains no plasticizers and is environmentally friendly. Coupled with flexibility and formability, the ease with which aluminium foil can be coated, printed, laminated, slit, cold-formed and embossed qualifies it as an extremely versatile tool for the pack designer.
Water contact angles have been used to estimate surface cleanliness before and after cleaning operations, ease of wettability of surfaces by waterborne coatings and the effectiveness of rinsing processes. 5.6 An organic liquid such as a solvent also can

Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. The degree of wetting (wettability) is determined by a force balance between adhesive and cohesive forces.Wetting deals with the three phases of materials: gas, liquid, and solid.
materials are its outstanding wettability and robust bonding to a wide range of lacquers, adhesives, films and coatings.
