The cost reduction direction of the Cosmetic tubes

Cosmetic tubes are made of multi-layer composite materials (typically plastic/aluminum foil/plastic + ink + coating), involving multiple processes such as co-extrusion, printing, and pipe manufacturing. The potential for cost reduction lies in multiple links. Let's analyze what the core cost reduction technology directions for cosmetic tubes are.

Under the premise of ensuring core quality attributes such as barrier properties (preventing deterioration of contents and loss of aroma), mechanical strength (compressive resistance, bending resistance, and drop resistance), sealing performance, printing effect, and user experience , waste is eliminated and efficiency is improved through design optimization, material innovation, process upgrading, and standardization. The following is a detailed explanation of the cost reduction measures, implementation paths and key points to note for hose packaging materials from the perspective of product technology:

1. Structural Optimization and lightweight

Pipe wall thinning: It is necessary to ensure that after thinning, the pipe body has sufficient stiffness to prevent collapse and deformation during transportation and shelf life. Optimize the layer thickness distribution, thinning in non-critical areas and maintaining or slightly increasing the thickness in critical areas.

Pipe size optimization: Simplify the design of pipe shoulders/pipe heads: Avoid overly complex or heavy pipe shoulder transition designs. Under the premise of meeting the matching, sealing and aesthetic requirements of the cap, optimize the shape of the pipe shoulder and the distribution of wall thickness.

Tail optimization: Evaluate more economical tail sealing methods. Under the premise of meeting the sealing requirements, choosing a simpler tail sealing method may reduce costs.

2.Material Innovation and Substitution

High cost-performance base material selection: Evaluation of different grades/grades of resins: Under the premise of meeting performance requirements (such as melt index, density, chemical resistance), cooperate with suppliers to evaluate PE and PP grades with higher cost performance.

Ink and coating Optimization: Evaluating ink systems with better cost performance: Under the premise of meeting the requirements of wear resistance, migration resistance, content resistance, and color, compare the comprehensive costs of different brands/types of inks.

Increase the proportion of recycled material (PCR) usage: PCR material is typically used in non-contact layers (middle layer or outer layer). The inner layer in contact with the contents still needs to use food/cosmetic grade virgin materials to ensure safety. Dark tubes may accept a higher proportion of PCR.

High-barrier and lightweight alternatives: Aluminum-coated film (VMCPP/VMPET) replacing aluminum foil: Aluminum-coated film is thinner, lighter, more flexible than pure aluminum foil, usually has a lower cost, and has certain barrier properties.

3.Manufacturing Process and Efficiency Improvement:

Enhancing printing and laminating efficiency: High-speed printing/laminating: Utilizing more advanced printing machines and laminating machines to increase production speed and reduce unit costs. Regular maintenance: Ensure that the mold is in the best condition.

Mold optimization and maintenance: Increase pipe-making speed: Upgrade pipe-making equipment to enhance output per unit time. Reduce the rate of poor sealing at the end: Optimize the parameters of heat sealing temperature, pressure and time, enhance online detection, and reduce the waste pipes caused by loose sealing, missed sealing and deformation at the end. Reduce pipe head/tail waste: Optimize the pipe cutting process. The above are several aspects that need to be considered to reduce the cost of cosmetic tubes.

Next time, let's continue to seek measures steps to cut the cost of cosmetic tubes.
