The future development prospects of hand sanitizer cosmetic packaging material hoses are promising

It is understood that we usually use various cosmetic packaging material hoses to make hand sanitizer bottles. Although the appearance and use are different, the same is that they are all spray-type cosmetic packaging material hoses, and some have unique appearance bottles. They are placed indoors as decorations, and these bottles can be reused after a single use. There are several types of hand sanitizer cosmetic packaging material hoses: foam cosmetic packaging material hose, push-on cosmetic packaging material hose, squeeze or cosmetic packaging material hose.
Most people add other things directly after using the water or cosmetics inside. In fact, it is best to clean them after use, because some sediment in the water will be If it accumulates at the bottom of the bottle, if it is not cleaned up, it will affect the newly injected water and will form some difficult-to-clean dirt in the long run.
In addition, the quality of these cosmetic packaging hoses is also dependent on the quality. Try to choose cosmetic packaging hoses that are free of odor, black spots, cracks, etc., and cooked plastic (also known as Soft plastic) is better. These materials have good toughness and plasticity, and they are not easy to break, and the use time is relatively long. Raw plastics, also known as hard plastics, are brittle and easy to break, especially in direct sunlight. Under the condition, it will easily fade and become more brittle, and cannot accept heavy pressure. Therefore, when choosing, we should try our best to choose those soft plastics. After use, they must be cleaned before they can be used again to avoid contamination.
Main problem
(1) When designing an extruded cosmetic packaging material hose, if the material is high-density polyethylene or polypropylene, the cross-section of the cosmetic packaging material hose should be rectangular or oval. Ethylene or other flexible cosmetic packaging material hose, the cross section is preferably round. This makes it easier for the contents to be squeezed out of the cosmetic packaging tube. The plastic parts used in conjunction with the hose mouth of cosmetic packaging materials are mainly bottle caps and sealers. The design of the cosmetic packaging material hose mouth should be focused on; consider how to make the cosmetic packaging material hose mouth better match the lid and sealer. The bottom of the cosmetic packaging material hose is the weak part of the mechanical properties of the cosmetic packaging material hose. . Therefore, the bottom of the cosmetic packaging material hose is generally designed to be concave; the corners and the inner recesses of the cosmetic packaging material hose are all made larger arcs. In order to facilitate the stacking of cosmetic packaging material hoses and increase the stacking stability of the cosmetic packaging material hoses, the bottom of the cosmetic packaging material hose should be designed with an inner groove.
(2) When labels are used on the surface of the cosmetic packaging material hose, the label surface should be flat. A 'frame' can be designed on the surface of the cosmetic packaging material hose, so that the label can be positioned accurately without movement. In blow molding, the first part of the parison that is blown into contact always tends to harden first. Therefore, the wall thickness of this part is also larger. The edge and corner part is the last contact part of the parison inflated, and the wall thickness of this part is small. Therefore, the edges and corners of the cosmetic packaging material hose should be designed with rounded corners. Change the surface shape of the cosmetic packaging material hose. For example, the middle part of the cosmetic packaging material hose is relatively thinner, and increasing the circumferential grooves or ribs on the 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 hose under long-term load.
(3) The printing surface of the cosmetic packaging material hose is the most concentrated part of consumers. The printing surface should be smooth and continuous; if the cosmetic packaging material hose contains handles, grooves, ribs and other structures, the design should be careful not to cause inconvenience to the printing operation. The oval-shaped cosmetic packaging material hose has higher rigidity, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the cosmetic packaging material hose, in addition to selecting high-rigidity materials, the shape design of the cosmetic packaging material hose must also be used to enhance the rigidity and load resistance of the cosmetic packaging material hose.
(4) Since most plastics have notch sensitivity, cosmetic packaging material hoses are prone to cracks and cracks at sharp corners, roots of mouth threads, necks, etc., so these parts should be designed as Rounded corners. For the transfer point of the rectangular cosmetic packaging material hose, it is necessary to support most of the load of the cosmetic packaging material hose. Therefore, locally increasing the wall thickness at this point is also beneficial to improve the rigidity and load resistance of the cosmetic packaging material hose.
