    Abstract: Laminate film structures including an adhesive layer having gas and moisture barrier properties are disclosed. The disclosed laminate film structures comprise films bonded together with an adhesive composition, the adhesive composition having barrier properties, e.g., controlling oxygen and/or water vapor transmission rates. The disclosed laminate film structures comprise films made from polymers and/or metallized polymers whereby the weight, thickness, and/or number of film layers has been reduced by using a barrier adhesive in place of a standard adhesive while still achieving similar barrier properties. Methods for forming laminate structures having a desired barrier performance are also disclosed, the methods comprising determining the desired barrier performance of the laminate structure, selecting a barrier adhesive, selecting two or more film layers, including at least a first film layer and a second film layer, applying the barrier adhesive on a surface of the first film layer, and bringing a surface of the second film layer into contact with the barrier adhesive applied on the surface of the first film layer, thereby forming the laminate structure having a desired barrier performance.

    Abstract: The present disclosure relates to a multilayer stretch film comprising at least a first layer, wherein said first layer comprises a polyolefin resin. The film of this aspect of the disclosure further include at least a second layer, and a mechanochromic dye which may be in any or all layers of the film. Another aspect of the disclosure is a method of promoting optimal stretching of stretch film during a wrapping operation, which method comprises at least the following steps. A polyolefin resin is selected that has a given density. Selecting a mechanochromic dye based on its ability to agglomerate in an unstretched film made from the polyolefin resin having the given density, such that when the dye is included in the film, the unstretched film will exhibit a first color. Admixing the mechanochromic dye into a melt of the polyolefin resin. Forming a film from the admixture of the previous step. Wrapping an object using the film of the previous step, while stretching the film to a level where a change from the first color to a second color can be observed.

    Abstract translation: 本公开涉及包含至少第一层的多层拉伸膜，其中所述第一层包含聚烯烃树脂。 本公开内容的该方面的膜进一步包括至少第二层和可以在膜的任何或全部层中的机械变色染料。 本公开的另一方面是促进包裹操作期间拉伸膜的最佳拉伸的方法，该方法至少包括以下步骤。 选择具有给定密度的聚烯烃树脂。 基于其在由具有给定密度的聚烯烃树脂制成的未拉伸膜中聚集的能力选择机械变色染料，使得当包含染料时，未拉伸膜将呈现第一颜色。 将机械变色染料混入聚烯烃树脂的熔体中。 由前一步骤的混合物形成薄膜。 使用上一步的胶片包装物体，同时将胶片拉伸到可以观察到从第一种颜色变为第二种颜色的水平。
