The components of the multi-layer composite stand-up pouch are mainly polyethylene (PE), nylon (NY), aluminum (AL), cast polypropylene film (CPP film), and the use of PE raw materials can make the printing effect good and not fade, using NY material. The oxygen permeability of the package can be minimized. The use of AL aluminum metal is mainly to block the light and heat effects. The innermost one is cpp film, cooking grade CPP (Retort CPP, RCPP for short), and LLDPE, LDPE, HDPE, PET, Compared to other films such as PVG, the cost is lower and the output is higher. It is stiffer than PE film. Excellent moisture and odor barrier properties. Versatile, can be used as a base film for composite materials. Metallization can be performed. As a food and commodity packaging and packaging, it has excellent demonstration properties, so that the product is still clearly visible under the packaging. These different materials are combined in scientific proportions to achieve safe packaging and standing requirements.
