This creation is about a flavor stacking structure. A flavored laminated structure, which comprises a barrier layer and a printed layer; on the other hand, the original laminated structure is used in the manufacturing method of containing water, beverage and vegetable juice or fruit. [Prior art]

“Polymers usually have a kind of taste and unpleasant taste” and become sensory characteristics. This is why plastic tastes and smells like plastic. This inherent characteristic of polymers is that low molecular weight polymers are oxidized when they are heated, and the degree is different in various polymers. Therefore, polyethylene ^ C poryethyl ene ^ PS is polyethylene terepthalate (PET). And polypropylene (PP) comes high. Generally, when the temperature rises above the ambient temperature, the sensory characteristics are enhanced. Processing conditions, such as machine temperature and pressure, often trigger the sensory characteristics of polymers. Therefore, when the finished film or laminated sheet is processed and formed, the packaging container formed will usually incorporate the taste and odor of plastic, especially in Sealing layer usually made of polyethylene film. In food packaging containers made of film or laminated sheet, the taste and aroma contained in the food are already present before packaging. Because the odor and taste generated in polymer films or laminated sheets (such as PE film) are inherent ’, food contamination will inevitably occur when used in food packaging, making

M260539-Case No. Luzhou 5214 Date: 4th, Creation Instructions (2) After a period of time, the taste of the food will be different from that before packaging. According to the observation, the 'food', especially the liquid in the dilute solution, will show a taste change, which indicates that the taste of the food is different from that in the past due to the packaging. This is because the oxidized polymer is diluted into the liquid food. For liquid products with strong taste, such as grapes, or concentrated foods, such as fruit drink powders, the taste of the polymer can be masked, but in the case of a diluted solution, the taste of the polymer becomes very obvious. U.S. Patent No. 4,988,546 issued on January 29, 1991, discloses a multi-layered structure 'including a load-bearing layer, made of a sheet of material that increases the rigidity of the laminated sheet, with a low density on each side The improvement of polyethylene is to add a buried layer made of low density polyethylene polymer and polymer flavor / aroma concentrate, and a layer made of low density polyethylene polymer. Product contact layer. This upper layer can be thermally welded to the outer layer of low-density polyethylene to increase the aroma of the product in the range of 2 to "ρ-500 ° F." U.S. Patent No. 4,35,876, issued on September 28, 1982, generally discloses laminated films and sheets. In particular, these laminated films and sheets each have a layer of polyethylene resin. Such a polyethylene resin layer has both Heat resistance and thermal stability. U.S. Patent No. 5,863,964, issued on January 26, 999, discloses a lining composition for sealing elements of potable fluid containers, which composition includes an inorganic sulfite, such as sodium sulfite, and / or tocopherol compounds , Such as (Π-(tocopherol, vitamin E), used to prevent odor caused by aldehydes in the fluid.
