The pattern on the packaging bag of sauce products always darkens and fades, and it is easy to compound delamination and packaging broken bags. Are these problems driving you crazy? This article will be from the sauce, sauce products packaging bag fading reasons, why broken bags, how to avoid these two aspects for your advice.
The reasons for the fading of the bags of sauce and sauce products make the design of the sauce and sauce products dark and faded. There are two main reasons: the ink color of the pattern is darkened through the darkening of the sauce, or the ink on the packaging film is discoloring by the salt and spicy substances of the sauce, the sauce products, and the reasons for the delamination of the composite film of the sauce and sauce products are mostly due to the packaging. The oil and salt permeate through the inner membrane and erode the adhesive.
Why are bags broken and how to avoid them? Most of the broken bags of plastic composite packaging of sauce and sauce products are due to the paste and other products stuck on the sealing part of the packaging bag, without heat sealing. Therefore, special attention should be paid to the plastic composite packaging of sauce and sauce products: 1. If the background color of sauce and sauce product packaging cannot cover the color of sauce and sauce product, the color of packaging pattern will become dark. Therefore, in the design of packaging patterns, the color of the contents should be estimated, and the background color should be deepened or the covering power should be strengthened. The color of sauce and sauce products should not pass through or less through the background color of the design. 2, the compound inner membrane of sauce and sauce products should be selected with oil resistant, gas resistant, salt resistant and strong corrosive films. Do not use single component adhesive which does not solidify glue film to prevent the oil, salt and spicy substances from sauce and sauce products from penetrating the inner film and compound film, so that the printing ink will not be eroded. It won't fade because of erosion. 3. In addition to the inner film with strong impermeability and leakage, the two-component polyurethane adhesive should be used for the packaging of sauce and sauce products. Properly increasing the amount of glue and prolonging the curing time of the composite film make it difficult for the oil, salt and pungent substances in sauce and sauce products to penetrate into the inner membrane. But causes the curing compound adhesive layer to stick back, or penetrates the adhesive film and corrodes the ink layer. This will greatly reduce because of the composite adhesive and deinking, resulting in composite packaging film delamination phenomenon. 4. By improving the tools for filling and filling sauce products and avoiding polluting the sealing part of the packaging bag, the failure of heat sealing can be reduced, and the damage rate of the packaging bag can be reduced.
