Recently, DuPont introduced the Cool2Go film, which is mainly used for beer can packaging and aims to keep the beer at a lower temperature for a longer period of time. Although this insulating and winding film has only a thin layer, it can isolate the heat transmitted from the outside, such as: the temperature of the hand and the temperature of the environment. This stretch film laminates a high-tech polymer insulation between Duijin's Teijin filmsTM and Melinex's two-layer film, so the process produces a film that locks in the cold, which is what beer drinkers expect. .
