Introduction to the appearance and characteristics of the plastic transparent cosmetic packaging material hose of the cosmetic packaging company

The appearance and characteristics of the transparent cosmetic packaging material hose: the rigidity is also high, and the oval cosmetic packaging material hose. However, the manufacturing cost of the mold is relatively high. Therefore, in order to ensure the rigidity of the cosmetic packaging material hose, in addition to selecting materials with high rigidity, the appearance design of the cosmetic packaging material hose must be used to enhance the rigidity and load resistance of the cosmetic packaging material hose.


To show good advantages and functions, the cosmetic packaging material hose should have sufficient rigidity and beautiful appearance. Be able to demonstrate its role in different industries. The common shapes of cosmetic packaging material hoses are round, square, oval and so on. From the perspective of use, each has its own advantages and disadvantages. The round cosmetic packaging material hose has high rigidity, but its appearance is not beautiful. The square cosmetic packaging material hose is beautiful in appearance, but it is not easy to control the uniform wall thickness of the cosmetic packaging material hose during forming. Cosmetic packaging material hoses can not only have a good appearance, but also have good product performance and advantages, ensuring that they can make important contributions in use.


It should be noted that the shape of the cosmetic packaging material hose should be symmetrical. Minimize the stretch points and parts of the mongoose. All transitions adopt circular arc transitions.


1 In order to make the wall thickness of the cosmetic packaging material tube uniform.


The place where consumers' attention is concentrated. The printed surface should be smooth and continuous; if the liquid cosmetic packaging material hose contains handles, grooves, ribs and other structures,


2 The printing surface of the cosmetic packaging tube. Care should be taken not to cause inconvenience to the printing operation when designing.


The label surface should be flat. A “frame” can be designed on the outer surface of the cosmetic packaging material hose to accurately position the label,


3 When labels are used on the outer surface of the cosmetic packaging material hose. No movement occurs.


For example, the middle part of the cosmetic packaging material hose is relatively thinner,


4 Change the outer shape of the cosmetic packaging material hose. Increasing the circumferential grooves or ribs on the outer surface of the cosmetic packaging material hose can improve the rigidity and bending resistance of the cosmetic packaging material hose. The longitudinal grooves or ribs can eliminate the deviation, sagging or deformation of the cosmetic packaging material hose under temporary load.


If the material is high-density polyethylene or polypropylene,


5 When designing squeeze type cosmetic packaging material hose. The cross-section of the cosmetic packaging material hose should be rectangular or oval. For the material of low-melt polyethylene or other flexible cosmetic packaging material hoses, the cross-section should be round. This makes it easy for the contents to be squeezed out of the cosmetic packaging tube.


The first contact part of the parison inflated,


6 When blow molding. Always tend to harden first. Therefore, the wall thickness of this part is also larger. The edge and corner part, the part where the parison touches after the parison is inflated, has a smaller wall thickness. Therefore, the edges and corners of the cosmetic packaging material hose should be designed with rounded corners.
