2020-01-14 16:43

How much thickness should we choose when choosing a stretched film? Can the thickness of a stretched film be selected? How should the thickness of a stretched film be selected? Generally speaking, the thickness of a stretched film is generally used and standardized by the market To decide, regarding the choice of the thickness of the stretched film, let's listen to the sharing of the technical staff of Qianghui's stretched film manufacturers!

1. The thickness of the stretched film can be based on the maximum number of microorganisms allowed per unit volume or unit surface area. This method is considered to be the first mold-resistant packaging product that is very sensitive to microorganisms. The key is to determine the types of microorganisms in the product and their reproduction and Growth pattern.

2. The thickness of the stretched film can be selected according to the maximum allowable water absorption of the packaged product or the maximum allowable dehydration of the product. It is concluded that this method is mainly applicable to the product's moisture-proof packaging planning. The key is to calculate the moisture permeability coefficient of the stretched film.

3. The thickness of the stretched film can be selected based on the maximum allowable oxygen absorption of the packaging product. This method is considered to be the first product suitable for oxygen-sensitive product barrier packaging. The key is to calculate the oxygen permeability coefficient of the stretched film.

4. The thickness of the stretched film can be selected according to the maximum carbon dioxide or oxygen permeability promised by the stretched film. It is concluded that this method is mainly for aeration and safe packaging of the product. The declared active product requires both stable oxygen and Need bright colors. The key is to calculate the oxygen permeability coefficient and carbon dioxide permeability coefficient of the stretched film to inhibit the growth and reproduction of microorganisms with high concentration of carbon dioxide.

How to choose the thickness of the stretched film is mainly determined by the packaging intention and the shelf life of the stretched film, and the thickness of the stretched film is determined by the packaging intention and the shelf life of the product.
