In the context of rising prices of cosmetic bottle packaging raw materials, the direct way to reduce the cost of cosmetic bottle packaging* is to 'reductionFor soft cosmetic bottle packaging, it is not difficult to appropriately reduce the size and thickness; for hard cosmetic bottle packaging, it is not difficult to appropriately reduce the weight, but it is a challenge to technological innovation to reduce it to a certain extent. When cosmetic bottle packaging materials are used to package things in cosmetic bottles, their volume properties are used, but their price is determined by the surface area properties. For example, a cylindrical cosmetic bottle packaging bottle/box/can, the same volume, under what circumstances, what is the ratio of the length to width of a turnover box and how to design the turnover box for the same volume? The utilization rate of the container is the issue that a cosmetic bottle packaging engineer must consider. These differences can significantly reduce the cost. Its design principle is to use the contraction force of the spring and prevent air from entering the bottle. , Resulting in a vacuum state, and using atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the spring force and atmospheric pressure cannot give enough force, the piston cannot fit too tightly with the bottle wall, otherwise the piston will not be able to move forward due to excessive resistance; on the contrary, if the piston is to be moved forward easily and the material leakage is prone to occur, Therefore, airless bottles have very high requirements for manufacturers. The structure development of packaging materials does not mean that the more complex the better, on the contrary, the simpler the structure is, the better it can meet the various functional requirements. The structure is simple, the mold is simple, the assembly is simple, and there are fewer problems. Simplify the mold structure. The development of the packaging material structure must be designed under the conditions that can meet the mold opening. It is very important to understand the mold structure and the molding method. Don't design for a long time, and the mold cannot be opened, then it will be embarrassing. The mold can be opened, and the mold structure must be simplified. Simplify the principle, minimize undercuts, and control the cost of packaging materials. This is also the core part of the package. The level of cost determines the company's profit, which is for pure plastic packaging material factories. Choose low-priced materials as much as possible for the selection of materials, on the basis of meeting the same conditions. To meet the appearance requirements, reduce the number of accessories, simplify the product structure, and make every structure useful. This also saves the cost of the mold. Choose reasonable matching methods for packaging materials. According to the appearance requirements, select reasonable, high suburban, low-cost surface treatment methods. If the fruit can be directly processed on the mold surface, there must be a set of standard controls on the development progress of new packaging materials to prevent Unnecessary mistakes, so as not to cause delays in delivery. Under permitted conditions, try to use mature products that are commercially available for cooperative development. For example, the use of general-purpose tooth mouth products and preform products on the market is a great help in reducing the cost of the package material product and advancing the development schedule.
