Carton and carton should not be used as adhesive

Production of wine boxes, food boxes, gift boxes generally have to go through surface paper offset printing, bronzing, lamination, corrugated lamination, steel wire die-cutting and many other processes. The correct selection of the binder in the box-type package binding process will play a decisive role in improving the quality of the cartridge package in terms of hardness, adhesive fastness, and drying properties.
High-grade wine boxes and gift boxes require that the products that are pasted out are not mildewed, smooth and firm, have good drying properties, and are wide in angularity, and the physical and chemical properties of the adhesive are appropriate and stable.
Under normal circumstances, the adhesives used for the manufacture of cartridges are usually made of white latex, polyvinyl alcohol, vegetable starch, dextrin, and scouring alkali. When selecting the adhesive, the physical and chemical properties of the adhesive should be taken into consideration in the influence of the adhesive on the paper, ink, galvanized aluminum foil and film used, and the production of the adhesive should be reasonably arranged according to its properties and chemical properties, otherwise it will affect Quality of products.
Once, due to negligence in our work, in the production of an upscale wine box for a brewery, the use of scoroders as binders for corrugated paper and other papers resulted in the loss of the original foil on the paper. The luster, the color becomes pale yellow, and the adhesion drop accident. The customer demanded a return, causing the company to suffer greater economic losses.
Afterwards, after a few days of sampling and research, we discovered that it was a problem with the selected binder, beryl alkaloid, and that Cautuanjing had a detailed physical and chemical analysis of scopolamine. The chemical name of scorodin was sodium silicate. It is a colorless crystal or white powder that is made of quartz sand and sodium carbonate, and is soluble in water. Its transparent slurry solution is called “water glass”. Its physical properties vary with the ratio of sodium oxide and silica in the finished product. It is decomposed by acid, precipitates silicic acid colloidal precipitates, and is used as a filler in industries such as soap and papermaking. Can also be used as an adhesive.
Since the pH value of the paper is 7 and it is a neutral substance, babbling alkali is weakly alkaline. Using it as an adhesive for high-grade wine boxes will make the paper slightly alkaline. Alkaline substances will have a certain influence on galvanized aluminum foils, inks, powders, and silver powders. They will also cause certain chemical reactions, especially chemical reactions with the metal powders in aluminum foils, which will cause the loss of bright and bright flashes of electro-aluminum foil. The original luster, the color completely turned pale yellow. Over time, it can also tarnish the ink layer on prints. Therefore, in the carton, carton paste box absolutely not use scocholine as a binder. As for what kind of adhesive, we must first analyze the physical and chemical properties of the adhesive, as well as its acid, alkali on the paper, ink, electrochemical foil, gold powder, silver powder and coating and other plugging. White latex, corn starch, polyvinyl alcohol, dextrin, and other types of binders are generally preferred. At present, babuloic acid has been listed as an internationally prohibited adhesive for use in cartons and cartons.
