Different packaging film thickness calculation method is not the same

although packaging film is a little layer of film, but it is also has a thickness, so how to clear our packaging film thickness. Different packaging film thickness calculation methods are different, we need according to the actual packaging film when calculating the thickness of the product for the calculation of thickness, generally has the following several ways:

1, according to the unit volume or surface area the number of microorganisms is clear, the method is mainly suitable for products of microbial keen anti-mold packaging, its key is clear product microbial species and their reproduction growth rule, etc.

2, according to the water absorbing capacity of the packaging product or products to take off the water clear, this method is mainly used moistureproof packaging design of products, the key is to calculate the permeability coefficient of packaging film.

3, according to the specific oxygen uptake of the packaging products, the method is suitable for main products partition of oxygen sensitive products packaging, the key is to calculate the air coefficient of packaging film.

4, according to the packaging film allows the amount of carbon dioxide and oxygen permeability is clear, the method is mainly for product packaging, inflatable insurance with statement activity products both need oxygen insurance or keep bright-coloured colour and lustre, high concentrations of carbon dioxide and needed to control the growth of microorganisms, the key is calculation of packaging film oxygen transmission coefficient and the carbon dioxide permeability coefficient.

that's several methods of packaging film thickness, but there is a simple method is directly related to manufacturers, let the manufacturer tell us the answer, so that you don't have to calculate itself!
