There at least two reasons that will make aluminum foil smell bad. Firstly, it is about oil contamination on its own. The oil contamination can be called the extra oil on surface of the aluminum foil which appears after rolling procession. These oils are dirty with complex components. They were thrown from the roll neck or the opening position of the machine, splashed and dripped on the foil surface. The harm of the oils which are on the surface of the aluminum foil is bigger than the other rolled materials. There are two reasons for this. On the one hand, most of the finalized aluminum foil must be with a cleaning surface as decorative and packaging material. On the other hand, it is of thin thickness on its own, which is easy to have bubbles when it is annealed. And oils will be formed into too much remains. Secondly, it is about the printing. For examples, when we used aluminum foil as chocolate wrapper. Most customers ask for customized printing. To produce the one without any odor, we not only need to choose aluminum foil with high quality, but ask our factory to buy brand machine with high quality. One thing we can sure, as the vendor of Disney, our aluminum foil for chocolate wrapper is without odor, and can maintain the original flavor of food.

Different styles of products, the relative production processes, production processes and labor costs will be different. The production process is simple, easy to shape plastic bags, the price will be relatively cheap; The bags be produced through the machine in large quantities, the price will be relatively low, if the bags request be manually or semi-manual production, the price is relatively high.3. Size specifications: The size of the plastic bag determines the amount of raw materials required for the production. Usually, the larger size, the higher price. Then, the printing area(size) also will affect the price too(As point 5).4. Material thickness: The different thickness of the material, the price is different too. The same size specifications of the plastic bags, the thickness be thicker, the more raw materials be consumed, so that the price will be higher.5.

Chocolate is fermented and roasted with cocoa beans, and added to milk powder, sugar, stirring and coagulation after the cocoa butter is squeezed. Compared with other vegetable oils, cocoa butter is more likely to absorb odor. The remaining portion of chocolate which is stored in the refrigerator without being re-wrapped will be contaminated by other things. But the aluminum foil will prevent odor. Meanwhile, aluminum foil also has thermal insulation to prevent melting and deterioration. Sometimes the surface of chocolate will be covered with a layer of white frost, which is a phenomenon caused by the frosting effect of lipids. When the cocoa butter is under the situation of above 28 degrees Celsius, it tends to precipitate out of the interior and rest on the surface of the chocolate, but it is harmless to the human body and does not affect the taste of chocolate. The aluminum foil from Kolysen Packaging not only has no odor, but it can maintain the original flavor of food, and also have the ability to enhance customers’ appetite, with 100 % news raw material and brand new machine for printing.
