What are the problems in the production of cosmetic plastic tubes?

2021-10-24

The use of cosmetic plastic tube is very common in life. It is the habitat of many cosmetics and skin care products, and it is convenient to use and easy to carry. It has been recognized by customers, but plastic cosmetic tube manufacturer will have a lot problems to deal with during bulk cosmetic tubes production. Some problems will affect our work, so what problems will cosmetic tube suppliers encounter in production?

First of all, when using labels on the surface of the cosmetic plastic tube, the label surface should be flat. A "frame" can be designed on the surface of the cosmetic plastic tube, 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 part where the parison is in contact with inflation, and the wall thickness of this part is small. Therefore, the edges and corners of the cosmetic plastic tube should be designed with rounded corners. Changing the surface shape of the cosmetic plastic tube, for example, the middle part of the cosmetic plastic tube is relatively thinner, and increasing the circumferential grooves or ribs on the surface of the cosmetic plastic tube can improve the rigidity and bending resistance of the cosmetic plastic tube. The longitudinal grooves or ribs can eliminate the deviation, sagging or deformation of the cosmetic plastic tube under long-term load.

Second, when it comes to designing an extruded cosmetic plastic tube, if the material is high-density polyethylene or polypropylene, the cross-section of the cosmetic plastic tube should be rectangular or oval, and for the material it is low-density polyethylene or other flexible cosmetic plastics. Tube, its cross-section is preferably round. This makes it easy for the contents to be squeezed out of the cosmetic plastic tube. The plastic parts used in conjunction with the cosmetic plastic tube mouth are mainly bottle caps and sealers. The design of the cosmetic plastic tube port should focus on how to make the cosmetic plastic tube port better match the lid and sealer. The bottom of the cosmetic plastic tube is the weak part of the mechanical properties of the cosmetic plastic tube. Therefore, the bottom of the cosmetic plastic tube is generally designed to be concave; the corners of the cosmetic plastic tube and the concave part are all made with larger arcs. In order to facilitate the stacking of cosmetic plastic tubes and increase the stacking stability of the cosmetic plastic tubes, the bottom of the cosmetic plastic tubes should be designed with internal grooves.

The third point is that the printing surface of the cosmetic plastic tube is where consumers' attention is focused. The printing surface should be smooth and continuous; if the cosmetic plastic tube contains handles, grooves, reinforcing ribs and other structures, the design should be careful not to cause inconvenience to the printing operation. The oval cosmetic plastic tube has higher rigidity, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the cosmetic plastic tube, in addition to selecting high-rigidity materials, the shape design of the cosmetic plastic tube must be used to enhance the rigidity and load-bearing strength of the cosmetic plastic tube.

Fourth, since most plastics have notch sensitivity, cosmetic plastic tubes are prone to cracks and cracks at sharp corners, roots of mouth threads, necks and other parts, so these parts should be designed with rounded corners. For the transfer place of the rectangular cosmetic plastic tube, it is necessary to support most of the load of the cosmetic plastic tube. Therefore, locally increasing the wall thickness at this place is also beneficial to improve the rigidity and load-bearing strength of the cosmetic plastic tube.

How to choose cosmetic tube for wholesale plastic packaging? What issues need to be paid attention to? All creative inspirations and design strategies come from the front line of the consumer market. Packaging cosmetic tube customization manufacturers have formulated a general design strategy for packaging cosmetic tubes through a series of studies on related companies, industries, products and consumers. Cosmetic packaging suppliers deeply analyze competing brands, avoid product confusion, and adopt four visual areas: main color, composition, image, and craftsmanship. The aesthetics, quality and affinity of wholesale plastic packaging cosmetic tube and the inherent quality of the product are reasonable in value to set off the high-end performance of the product, and bring additional benefits and psychological satisfaction to consumers.

Modern wholesale plastic packaging cosmetic tube is no longer just a product packaging with simple words or patterns. We choose bold and beautiful brand fonts, which have aesthetics and affinity for the main image, which constitute the main body of the content and highlight the sales proposition of the product. According to consumers' visual process habits, the main image, brand name, category name and general information are connected in series to make consumers see clearly. The plastic packaging cosmetic tube is constantly reviewed and improved to promote development and maturity. In the later stages of creation, subtraction is used to remove some flashy decorations, and use elements that can better express the product to tell consumers what product is in the packaged cosmetic tube.

Whether the cosmetics plastic tube packaging is important for appearance or function, both the industry and consumers are very concerned. Regarding the appearance of cosmetic plastic tubes, in the current fierce competition in various markets, the appearance of cosmetic plastic tube packaging is naturally valued by buyers. Of course, the production technology of cosmetic plastic tube packaging is constantly improving. From the shape of the cosmetic plastic tube to the label of the cosmetic plastic tube, the color and the bottle cap are constantly improving.

Let's talk about the functionality of cosmetic plastic tube packaging. In recent years, many cosmetic plastic tube packaging have been continuously enhanced in terms of functionality and humanized design. However, for the humanized design of cosmetic plastic tube packaging, the plastic cosmetic tube manufacturer must be closer to consumers, and improve according to consumers' habits and use scenarios.
